Is it necessary to cover and deodorize the sewage tank?

The covering of the sewage tank not only enables the enterprise to achieve environmentally friendly production, but also avoids the pollution and damage to the local environment during the production process.

Especially in sewage treatment plants and industrial wastewater treatment stations, the foul odors emitted during the wastewater treatment process have seriously polluted the local environment, causing significant impacts on the lives of surrounding enterprises and the general public. If not properly addressed, the environmental pollution will become uncontrollable.

Therefore, it is a wise choice to cover up areas with severe pollution from waste water and waste gas. Moreover, by covering the sewage tanks, the surrounding environment is effectively protected and the goal of purifying the foul gases from the sewage tanks is achieved.

What are the methods for covering the sewage treatment facilities?

There are two methods for adding a cover: one is to add a high cover, and the other is to add a low cover. The specific method for adding a high cover is to add a large cover with a height of about 1 to 5 meters on the structure that needs to be covered, covering all the pool surfaces and equipment (the walkway boards can be not covered inside); the specific method for adding a low cover is to add a cover with a height of no more than 2 meters on the water surface of the structure, exposing all the walkways and equipment outside the cover, and only covering the sewage surface. Using a high cover for the pool body can reserve sufficient maintenance space for the internal equipment. For areas with many moving equipment and heavy maintenance tasks, a high cover form is recommended. Using a low cover to seal the pool body can reduce the amount of exhaust gas, save equipment investment, and save operating costs.

Waste water treatment cover material

There are many types of covering materials. Among them, the lightweight covering materials suitable for the sealing of sewage tanks include: solar panels + steel frame, fiberglass reinforced plastic + steel frame, membrane materials, fully polypropylene materials, and fully fiberglass reinforced plastic materials.

Polyethylene (low cover) of the sewage treatment station

For large-scale urban sewage treatment plants with large pool spans, it is better to use new anti-corrosion membrane materials. For industrial enterprises, using fully PP or fully fiberglass reinforced plastic is more appropriate. When using other materials, since the steel frame support part inevitably lies inside the top cover, after the pool top is covered, the concentration of corrosive gases inside the pool increases by several times. Under the influence of sunlight radiation, the temperature is very high, and the internal steel structure is prone to corrosion. Generally, its lifespan is 2 to 3 years, meaning that within a short period of time, the entire structure will face the need for secondary construction.
