Cover and deodorize sewage treatment

Covering the sewage tank not only achieves environmentally friendly production for enterprises, but also avoids pollution and damage to the local environment during the production process. Especially in sewage treatment plants, industrial wastewater stations, etc., the foul odor gases discharged during the wastewater treatment process seriously pollute the local ecological environment and have a serious impact on the lives of surrounding enterprises and people. If not treated, environmental pollution will become uncontrollable. Therefore, it is a wise choice to cover areas with severe pollution of waste gas and wastewater, such as sewage tanks.

Cover and deodorize sewage treatmentThere are many types of cover materials for sewage tanks, and lightweight cover materials that are more suitable for closed sewage tanks include polycarbonate sheets with steel frames, fiberglass reinforced plastic with steel frames, membrane materials, all PP materials, and all fiberglass reinforced plastic materials. From the above diagram, it can be seen that for urban sewage treatment plants with high investment and large pool span, it is better to use new anti-corrosion film materials, while industrial enterprises use full PP or full fiberglass, which is more suitable. When using other materials, the steel frame support part is inevitably placed inside the top cover. Due to the addition of a cover on the top of the pool, the concentration of corrosive gases inside increases exponentially, and the temperature is high under sunlight radiation. The internal steel structure is highly susceptible to corrosion, with a general lifespan of 2-3 years

Cover and deodorize sewage treatmentMainly generated in the sewage treatment process, including sewage pumping stations, inlet grilles, aeration sedimentation tanks, sludge treatment facilities, and sludge concentration, dewatering and drying, transportation, thermal drying, composting, etc. Different treatment facilities and processes can produce various types of odorous gases.
