Autotrophic denitrification filter sewage treatment equipment

Abstract

The invention discloses autotrophic denitrification filter sewage treatment equipment which comprises a device main body, a water inlet is formed in one side of the device main body, a clear water outlet is formed in the other side of the device main body, a movable bin cover is arranged at the top end of the device main body, and a sewage pretreatment tank is arranged on the inner side of the device main body. A denitrification filter tank is arranged on one side of the sewage pretreatment tank, a clean water tank is arranged on one side of the denitrification filter tank, a cleaning device is arranged on the inner side of the denitrification filter tank, a filtering device is arranged on one side of the cleaning device, and a backwashing device is arranged at the bottom end of the filtering device; according to the sewage treatment equipment for the autotrophic denitrification filter tank, the backwashing device, the filter device, the cleaning device and the sewage pretreatment tank are arranged, so that the backwashing cleaning effect of the device can be effectively improved, and the sewage treatment effect of the device is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an autotrophic denitrification filter tank sewage treatment equipment. Background technique [0002] In recent years, the way of aquaculture has changed from extensive culture and semi-intensive culture to intensive culture. However, due to the one-sided pursuit of economic benefits, the breeding density is too high, the breeding species is single, the balance of the natural ecological system in the breeding water body is broken, and the self-pollution serious. In addition, with the increase of aquaculture time, the aquaculture water will contain higher concentrations of organic pollutants such as nitrogen and phosphorus. If these water bodies are continuously discharged into the environment without corresponding purification treatment, it will cause eutrophication of the water body. , seriously affect the water quality of the environment and cause certain secondary pol...

AI Technical Summary

Problems solved by technology

[0002] In recent years, the aquaculture method has transitioned from the previous extensive and semi-intensive farming to intensive farming. However, due to the one-sided pursuit of economic benefits, the breeding density is too high, the breeding species is single, the balance of the natural ecological system in the breeding water is broken, and self-pollution serious

In addition, as the breeding time increases, the breeding water will contain higher concentrations of organic pollutants such as nitrogen and phosphorus. If these waters are continuously discharged into the environment without corresponding purification treatment, it will cause eutrophication of the water. , which seriously affects the water quality of the environmental water body and causes certain secondary pollution to the environment.

Moreover, with population growth and rapid economic development, the demand for water resources has also increased significantly. As an important source of water supply, lakes and reservoirs account for about 25% of the water supply. If the nitrate content of such water exceeds the standard, long-term Drinking will lead to methemoglobinemia, and also has the risk of cancer, which will seriously endanger human health
