Why are these water treatment units covered?

Why are these water treatment units covered? During an inspection some time ago, we found that many companies’ sewage treatment plants have been equipped with covers and treatment systems. * * Are there any new requirements? Or have companies never done it? Is this technique difficult? Please give expert guidance! Thanks!
Environmental protection requirements have become higher, and we have also added them.
Environmental protection requires the management of organic volatiles. The organic volatiles in the sewage plant pool need to be closed and treated before being discharged.
Mainly to prevent odor. I'm thinking: Many rivers in the city have been equipped with jet aerators, which increase the oxygen in the rivers and purify the river water. But the air is also filled with the stench from the stinking ditches. This spreads the corrosion of water bodies into the atmosphere. Which impact on the environment is greater?
This is different. The problem of quantitative change should be relatively strong at the beginning, and it will get better after a while.
Regarding this issue, I once posted a post in the environmental protection section. You can refer to a way to solve the odor of sewage treatment-add a cover to the sewage tank. https://bbs.hcbbs.com/thread-1340218-1-1.html (Source: Haichuan Chemical Forum Network)
During biochemical treatment and aeration, odors will be produced and then covered and absorbed by air.
After reading the post on Super Edition, it seems that the capping process started gradually from that time on, and it has become more popular in the past few years.
What process is used for subsequent processing? Does it work well? We are also investigating.

I saw a feasibility study material and the proposed data requirements are as follows: Table 3-1 The maximum allowable concentration of tail gas emissions at the design plant boundary (edge of the protective belt) (unit: mg/m3) Serial number control item secondary standard 1 Ammonia 1.5 2 Hydrogen sulfide 0.06 3 Odor concentration (dimensionless) 20 4 Methane (maximum volume concentration in the plant area, %) 1 I wonder if it can meet the requirements after being capped and deodorized?
