Problems solved by technology

The distribution of rural areas in my country is relatively scattered. If most of the rural domestic sewage is collected centrally for unified treatment, the investment in the construction of the collection pipe network is quite large, and the problem of pipe network blockage must also be considered.

Abstract

The invention discloses an integrated membrane bioreactor. The integrated membrane bioreactor comprises an anaerobic zone provided with a lining anticorrosive coating layer, an anoxic zone provided with a lining anticorrosive coating layer, an aerobic zone provided with a lining anticorrosive coating layer, a filtering zone provided with a lining anticorrosive coating layer, a MBR subassembly arranged in the filtering zone, a reflux pump, a filter pump, and an air blower. The integrated membrane bioreactor possesses following advantages: (1) treatment efficiency is high, and discharged water can be recycled directly; (2) system operation is stable, flow is simple, equipment is less, and occupied land area is small; (3) sludge age is old, and excess sludge production is low; and (4) operation management is convenient, and automatic control is convenient to realize. According to the integrated membrane bioreactor, activated sludge can be completed intercepted in the integrated membrane bioreactor; hydraulic retention time (HRT) and sludge retention time (SRT) are completed separated in the integrated membrane bioreactor, so that flexible and stable controlling can be realized; at the same time, automatic control is convenient to realize, and automation level of wastewater processing is increased.

Description

technical field [0001] The invention relates to sewage treatment equipment, which is mainly aimed at equipment for treating domestic sewage in rural areas or domestic sewage in small cities. Background technique [0002] At present, the water pollution caused by urban and rural domestic sewage in our country is becoming more and more serious, which is an important factor of water eutrophication. At present, our country is increasing the treatment of urban and rural domestic sewage. The distribution of rural areas in my country is relatively scattered. If most of the rural domestic sewage is collected for unified treatment, the investment in the construction of the collection pipe network is quite large, and the problem of pipe network blockage must also be considered. If the rural domestic sewage is collected and treated separately, the construction cost of the collection pipe network can be greatly saved. Contents of the invention [0003] The purpose of the present inve...
