MBR double-membrane process sewage treatment integration apparatus

Abstract

The invention provides an MBR double-membrane process sewage treatment integration apparatus. The apparatus comprises a facultative zone, an anaerobic zone, an aerobic zone, an MBR membrane zone, a clear water tank, a nanofiltration membrane zone and a device room, and the device room comprises a blower, a first medicament storage chamber, a second medicament storage chamber and an electric control cabinet. Solid-liquid separation is effectively carried out through an MBR membrane to make the separation effect better than the separation effect of a traditional sedimentation tank, and the turbidity and the suspended matter content of effluent water are close to zero, and the biological deamination effect in the invention is better than a conventional biological deamination effect; the apparatus also includes the nanofiltration membrane zone, so soluble ion salts, parts of organic matters and the chroma in the sewage can be effectively filtered out, thereby the water quality is further improved; and the apparatus also has the advantages of easiness in integration, standard unification, quantified production, high degree of automation, no manual backwashing, less manual operation, reduction of the operating cost, short construction period, low construction cost, and easiness in installation of standard modular devices.

Description

technical field [0001] The invention relates to the technical field of sewage treatment and regeneration, in particular to an integrated sewage treatment equipment using MBR technology. Background technique [0002] At present, my country's urban sewage treatment plants have achieved considerable development in terms of both quantity and quality. The completion and operation of a large number of sewage treatment plants with high treatment requirements provides a strong guarantee for reducing environmental burdens, reducing pollutant discharge, and improving water environment. However, the construction of urban sewage treatment plants in my country still has a certain gap compared with developed countries, and the amount of sewage treatment still lags behind the amount of sewage discharge. Moreover, for a period of time, high energy consumption, high operating costs, and insufficient collection of sewage treatment fees have led to difficulties in the operation of some sewage ...
