Abstract

The invention relates to the field of sewage treatment, in particular to an MBR (Membrane Bioreactor) sewage treatment system which comprises a regulating tank, an anoxic tank and an MBR membrane tank which are arranged in sequence, the sewage conveying pump can supply water to the adjusting tank; a grating, an aeration stirring device and a liquid level control device are arranged in the adjusting tank; the regulating tank is connected with the anoxic tank through a sewage lifting pump, a filler frame and a first aeration device are arranged in the anoxic tank, and filler is arranged on the filler frame; the anoxic tank and the MBR membrane tank are connected through a water inlet pump, a membrane assembly and a second aeration device are arranged in the MBR membrane tank, and the water outlet end of the membrane assembly is connected with a clean water pump. The method has the advantage that the defect that production sewage and domestic wastewater generated in the construction period of a power plant project pollute the environment and cause waste of water resources can be effectively overcome.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an MBR sewage treatment system. Background technique [0002] During the construction period of the power plant project, the discharge of wastewater is relatively large. According to the characteristics of the power plant project, the sources of wastewater during the construction period are divided into production sewage and domestic wastewater. Construction and production wastewater mainly comes from excavation of construction sites, wastewater from sand and gravel processing systems, washing of construction machinery and equipment, vehicle maintenance, oily wastewater from machine repairs, and concrete maintenance. The main pollutants of production wastewater are suspended solids and petroleum substances, and the main pollutants of site excavation drainage are sediment. Construction domestic sewage includes construction worker feces, shower sewage, washing sewage and kitchen oi...
