Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

Công ty môi trường( TNX) Tư vẫn, thiết kế và xây dựng hệ thống nước thải Khách sạn - Nhà hàng
1. Tư vấn, thiết kế và xây dựng hệ thống
xử lý nước thải Khách sạn – Nhà Hàng
[Công Ty Môi Trường – TNX]
Xử lý nước thải khách sạn là điều cần thiết nhằm tránh ô nhiễm
nguồn nước đô thị, nước thải sinh hoạt hằng ngày chúng ta
thường xã thẳng ra sông, kênh, rạch vì vậy nguồn nước đang bị ô nhiễm nghiêm trọng
và đe dọa trực tiếp hoặc gián tiếp đến con người. Nước thải khách sạn có thành phần ô
nhiễm chủ yếu là chất ô nhiễm hữu cơ nên chúng tôi lựa chọn công nghệ sinh học thân
thiện môi trường là phù hợp.
Các công nghệ mới và hiện đại mà Thảo Nguyên Xanh đã áp dụng như công nghệ :
AAO, MBBR, SBR,… giảm được diện tích 1/2 so với công nghệ truyền thống, không sử
dụng hóa chất.
1. Sơ đồ công nghệ xử lý nước thải khách sạn
2. 2. Thuyết minh sơ đồ công nghệ xử lý nước thải khách sạn
- Nước thải từ các nguồn phát sinh theo mạng lưới thu gom nước thải chảy vào hố thu
của trạm xử lý. Tại đây, để bảo vệ thiết bị, hệ thống đường ống công nghệ, song chắn
rác thô được lắp đặt để loại bỏ các tạp chất có kích thước lớn ra khỏi nước thải. Sau đó
nước thải sẽ được bơm lên bể điều hòa.
- Tại bể điều hòa, máy khuấy trộn chìm sẽ hòa trộn đồng đều nước thải trên toàn diện
tích bể, ngăn ngừa hiện tượng lắng cặn ở bể sinh ra mùi khó chịu. Bể điều hòa có chức
năng điều hòa lưu lượng và nồng độ nước thải đầu vào trạm xử lý. Điều hòa lưu lượng
là phương pháp được áp dụng để khắc phục các vấn đề sinh ra do sự dao dộng của
lưu lượng, cải thiện hiệu quả hoạt động của các quá trình tiếp theo, giảm kích thước và
vốn đầu tư xây dựng các công trình tiếp theo. Các lợi ích của việc điều hòa lưu lượng
là: (1) quá trình xử lý sinh học được nâng cao do không bị hoặc giảm đến mức thấp
nhất “shock” tải trọng, các chất ảnh hưởng đến quá trình xử lý có thể được pha loãng,
pH có thể được trung hòa và ổn định; (2) chất lượng nước thải sau xử lý được cải thiện
do tải trọng chất thải lên các công trình ổn định. Bơm được lắp đặt trong bể điều hòa để
đưa nước lên các công trình tiếp theo.
- Nước thải sau khi đi qua bể điều hòa được bơm lên bể SBR cải tiến để xử lý triệt để
các chất ô nhiễm: BOD, COD, ni tơ, photpho, ….. Tại đây, hệ thống khuấy trộn chìm và
hệ thống phân phối khí được lắp đặt trong bể. Khi hệ thống khuấy trộn chìm hoạt động,
môi trường thiếu khí được hình thành, quá trình xử lý ni tơ, phospho và các chất ô
nhiễm trong nước thải diễn ra mạnh mẽ.
Với việc lựa chọn bể bùn hoạt tính xử lý kết hợp đan xen giữa quá trình xử lý thiếu khí,
hiếu khí sẽ tận dụng được lượng cacbon khi khử BOD, do đó không phải cấp thêm
lượng cacbon từ ngoài vào khi cần khử NO3-, tiết kiệm được 50% lượng oxy khi nitrat
hóa khử NH4+ do tận dụng được lượng oxy từ quá trình khử NO3-.
Nồng độ bùn hoạt tính trong bể dao động từ 1.000-3.000 mg MLSS/L. Nồng độ bùn
hoạt tính càng cao, tải trọng hữu cơ áp dụng của bể càng lớn. Oxy (không khí) được
cấp vào bể SBR cải tiến bằng các máy thổi khí (airblower) và hệ thống phân phối khí có
hiệu quả cao với kích thước bọt khí nhỏ hơn 10 µm. Lượng khí cung cấp vào bể với
mục đích: (1) cung cấp oxy cho vi sinh vật hiếu khí chuyển hóa chất hữu cơ hòa tan
thành nước và carbonic, nitơ hữu cơ và ammonia thành nitrat NO3-, (2) xáo trộn đều
nước thải và bùn hoạt tính tạo điều kiện để vi sinh vật tiếp xúc tốt với các cơ chất cần
xử lý, (3) giải phóng các khí ức chế quá trình sống của vi sinh vật, Các khí này sinh ra
trong quá trình vi sinh vật phân giải các chất ô nhiễm, (4) tác động tích cực đến quá
trình sinh sản của vi sinh vật. Tải trọng chất hữu cơ của bể trong giai đoạn xử lý
aerotank dao động từ 0,32-0,64 kg BOD/m3.ngày đêm.
3. Công nghệ SBR cải tiến được vận hành gián đoạn theo mẻ. Chế độ vận hành linh hoạt.
Bể phản ứng vừa có chức năng xử lý sinh học, vừa có chức năng lắng. Nguyên tắc
hoạt động của bể SBR bao gồm chuỗi chu trình xử lý liên tiếp với các giai đoạn, các
pha sau:
* Giai đoạn 1: Giai đoạn cấp nước – Pha 1 Cấp nước vào bể SBR
Trong giai đoạn nạp nước vào bể, khí được cấp vào bể trong suốt quá trình nạp nước
thải vào bể. Khí sẽ hòa trộn đồng đều nước thải đầu vào trên toàn diện tích bể, tạo môi
trường thuận lợi cho quá trình xử lý các chất ô nhiễm diễn ra trong bể.
* Giai đoạn 2 Giai đoạn phản ứng – Pha 2 Tạo phản ứng sinh hóa giữa nước thải và
bùn hoạt tính bằng sục khí
Giai đoạn này ứng dụng quá trình sinh trưởng của vi sinh vật lơ lửng hiếu khí, bao gồm
vi khuẩn hiếu khí, vi khuẩn hiếu khí tùy tiện, nấm, tảo, động vật nguyên sinh, …, khi
nước thải được đưa vào bể với lưu lượng, thể tích nhất định dưới tác động của oxy
được cung cấp từ các máy thổi khí, vi sinh thực hiện quá trình phân hủy các chất hữu
cơ, chuyển hóa chúng thành CO2, H2O, các sản phẩm vô cơ khác và các tế bào sinh
vật mới.
Trong giai đoạn này cần tiến hành thí nghiệm để kiểm soát các thông số đầu vào như:
DO, BOD, COD, N, P, cường độ sục khí, nhiệt độ, pH… để có thể tạo bông bùn hoạt
tính hiệu quả cho quá trình lắng.
* Giai đoạn 3: Giai đoạn lắng – Pha 3: Lắng
Sau quá trình làm thoáng, nước thải trong các bể SBR được để yên và quá trình lắng
tĩnh bắt đầu diễn ra. Sau thời gian lắng nhất định, ta có thể nhận thấy sự phân tách lớp
bùn và nước trong bể.
* Giai đoạn 4: Giai đoạn chắc nước – Pha 4: Xả nước và bơm xả lượng bùn dư
Trong giai đoạn này, phần nước trong phía trên trong bể SBR được đưa sang bể khử
trùng. Một phần lượng bùn hoạt tính lắng dưới đáy bể được đưa sang bể chứa bùn.
Khi giai đoạn xả nước, xả bùn (nếu có) hoàn tất, nước thải tiếp tục được nạp vào bể
SBR để tiếp tục chu kỳ mới. Bể SBR có chế độ vận hành linh hoạt tùy thuộc vào lưu
lượng và tính chất nước thải đầu vào.
- Nước sau thời gian xử lý tại bể SBR cải tiến được bơm qua cột khử trùng. Nước thải
được khử trùng tại cột khử trùng trước khi thải vào nguồn tiếp nhận. Quá trình khử
trùng không dùng chất khử trùng. Chất lượng nước đầu ra đáp ứng yêu cầu xả thải cho
phép theo quy định hiện hành của pháp luật.
4. - Bùn ở bể SBR cải tiến được bơm tới bể chứa bùn để lưu trữ trong khoảng thời gian
nhất định. Sau đó, bùn được các cơ quan chức năng thu gom và xử lý theo quy định.
Tại bể chứa bùn, không khí được cấp vào bể để tránh mùi hôi sinh ra do sự phân hủy
sinh học các chất hữu cơ!
