AO and facultative MBR membrane integrated sewage treatment equipment

Abstract

The invention relates to AO and facultative MBR membrane integrated sewage treatment equipment which comprises a grating, a regulating reservoir, a single chip microcomputer and an MBR, the grating is connected with a water inlet of the regulating reservoir through a sewage pipeline, and a water outlet of the regulating reservoir is connected with the MBR through a sewage pipeline. Two steel plates are arranged in the MBR and divide the MBR into an anoxic tank, a facultative MBR aerobic zone and a clean water tank which communicate with one another in sequence, an electric flocculation device communicating with the anoxic tank is arranged above the anoxic tank, the electric flocculation device is connected with a water collecting tank through a water inlet pipe, and a lifting pump connected with the water inlet pipe is arranged in the regulating reservoir. A fixed suspension type flexible biological filler is arranged in the anoxic tank, a microfiltration membrane assembly is arranged in the facultative MBR aerobic zone, and a drainage pump module is arranged between the microfiltration membrane assembly and the clean water tank. Pollution of sewage to nearby water environment can be reduced, body health of people is protected, and environmental sanitation conditions of human beings are improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to AO + facultative MBR membrane integrated sewage treatment equipment. Background technique [0002] The results of the first national survey of pollution sources showed that the discharge of agricultural pollutants COD accounted for 43.7% of the total discharge, of which total nitrogen and total phosphorus accounted for 57.2% and 67.4% of the total discharge respectively. Agricultural sources basically account for more than 50% of the country's pollution, but most of the rural areas in my country do not have any sewage collection and treatment facilities. [0003] The wanton discharge of untreated domestic sewage seriously pollutes the rural ecological environment and directly threatens the health of farmers and the economic development of rural areas. On the one hand, untreated domestic sewage flows into low-lying rivers, lakes, ponds and other surface water bodies, ser...

Problems solved by technology

However, due to the wide and scattered distribution of the rural population in my country, large-scale pipeline network construction and centralized treatment in cities are not suitable for rural areas; at the same time, farmers' economic affordability is poor and their technical management level is low. Therefore, the operation is difficult, investment and Sewage treatment technologies with high operating costs are also difficult to promote
