Novel semi-ecological sewage treatment process

Abstract

The invention discloses a new process for semi-ecological sewage treatment, which comprises a sewage treatment tank, a sewage storage room is arranged at the lower part of the sewage treatment tank, a support layer is set above the sewage storage room, a filter material layer is provided above the support layer, and a filter material layer is arranged above the support layer. The material layer includes a filter layer and an organism ecological treatment layer. An aeration pipe is provided at the bottom of the sewage holding room. The bottom of the sewage holding room is also connected to a water inlet pipe. The other end of the water inlet pipe is connected to a sewage separator. The sewage separator includes a separation device and Circulating water treatment device. By combining physical purification and biological purification, the present invention avoids the problem of long purification time in the simple ecological treatment of sewage, and at the same time avoids the excessive pollution of sewage entering the ecological sewage treatment pool, which will cause the microorganisms to be in the sewage The environment is harsh, which leads to low sewage treatment efficiency, poor water quality after treatment, and the phenomenon that the water cannot be completely up to standard, which can ensure that the sewage can be completely purified.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a new semi-ecological sewage treatment process. Background technique [0002] Sewage usually refers to some polluted discharge water from domestic and production. With the acceleration of urbanization in our country, at present, the sewage discharge of small and medium-sized cities (towns) accounts for more than half of the total sewage discharge in the country. With the rapid development of urban construction in the next 50 years, the discharge of domestic sewage and industrial wastewater It will increase several times, even more than ten times, which will certainly aggravate the deterioration of the water environment. The deterioration of the water environment will affect industry, agriculture, and various fields of people's life and work. Therefore, considering the current status of sewage discharge in my country, it is imminent to treat sewage with high quality and ...

AI Technical Summary

Problems solved by technology

However, due to the harsh sewage environment where the microorganisms are located, the sewage treatment efficiency is low, the treated water quality is not good, and the standard cannot be completely met, and the equipment needs to be maintained frequently, and the sludge cleaning cycle is short, resulting in increased management costs and relatively high costs. high
