Abstract

The invention discloses a sewage treatment device, comprising a fan, a water pump and a tank body. The upper part of the tank body is provided with a sewage inlet and an exhaust port; a Z shape separator is fixed inside the tank below the sewage inlet; the Z shape separator comprises an upper baffle plate, a vertical baffle plate, a lower baffle plate, and divides the tank body into four regions; the upper baffle plate is provided with a plurality of reflux holes, the reflux holes are equipped with anti-reflux nozzles for preventing the water above the upper baffle plate from flowing to the lower position; a membrane module is fixed below the upper baffle plate, and a hanging membrane packing assembly is fixed above the lower baffle plate; a left aeration device is fixed below the membrane assembly, and is connected with a fan outside the tank body through a gas supply pipeline; a water inlet of the water pump outside the tank body is connected with a membrane assembly water outlet duct through a water pipes; and the gas supply pipeline and the water pipe are equipped with installation valves. The device integrates two sewage treatment technology and equipment of biological membrane method and a membrane bioreactor, and has the advantages of small land occupation, and low investment and operating cost.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a sewage treatment device using a membrane. Background technique [0002] Due to the increasingly serious problem of eutrophication in water bodies, the requirements for nitrogen and phosphorus indicators in discharged sewage have become more and more stringent. In the GB18918-2002 "Pollutant Discharge Standards for Urban Sewage Treatment Plants" issued by my country in 2002, the A standard of the first-level standard requires TP to be less than 0.5mg / l, ammonia nitrogen to be less than 5mg / l, and total nitrogen to be less than 15mg / l. Therefore, in the process of sewage treatment, special attention should be paid to the removal of nutrients such as nitrogen and phosphorus. [0003] The current typical sewage treatment process generally includes a combination of aerobic, anoxic, anaerobic, sedimentation and sludge treatment units. Different microorganisms in activated sludge can ad...
