Smart integrated MBR sewage purifying device

Abstract

The embodiment of invention provides a smart integrated MBR sewage purifying device. The device comprises an oxygen deficit pool, an aerobic pool, a membrane pool, a clear water pool and an equipmentroom. The oxygen deficit pool is communicated with the bottom of the aerobic pool, the aerobic pool is communicated with the top of the membrane pool, the clear water pool and the membrane pool are not communicated in the same pool, and the equipment room is next to the clear water pool and comprises a phosphorous removal system, a back flush system, a sterilizing system and an electric control cabinet; the oxygen deficit pool primarily filters sewage, a denitrification reaction occurs, the sewage has the denitrification reaction through the aerobic pool to generate nitration liquid, the membrane pool performs deep-layer filtering through an MBR membrane device and is connected with the phosphorous removal system to remote phosphorous in the sewage, and the clear water pool is connected with the sterilizing system to sterilize produced water by the membrane pool, so that clear water is obtained. By the adoption of the modularized design, the production period is controllable, quality is good, the structure is compact, the size is small, transportation and installation are simple, full-automatic operation can be realized, remote monitoring can be realized, and the demand for treating the sewage in villages and small towns can be met.

Description

technical field [0001] The invention relates to the technical field of sewage purification, in particular to an intelligent integrated MBR sewage purification device. Background technique [0002] With the continuous improvement of my country's urbanization level, residents' demand for sewage treatment is increasing day by day. However, more than 95% of villages and more than 90% of small market towns in China do not have perfect sewage collection and treatment facilities, and domestic sewage and some industrial wastewater produced , almost directly discharged into villages and towns without any treatment (rivers, ponds, groundwater, etc.), causing serious water pollution in villages and towns, not only destroying the overall environment and landscape of villages and towns, but also studies have shown that the occurrence of many diseases is related to the water environment Water pollution can promote the occurrence of some malignant diseases. [0003] Villages and towns are s...

Problems solved by technology

The effect of MBR sewage treatment is good, but the operation of the system involves water treatment, machinery, electrical automatic control, and even software, so the professional technical ability of maintenance and management personnel is also required.

Patent CN105731735A discloses a rural sewage treatment device, which adopts an automatic membrane cleaning device, that is, installs an ultrasonic vibrating plate on the wall of the membrane bioreactor tank and electrically connects the ultrasonic generator. However, during the operation of the device, due to mechanical equipment Fluctuations in operation and water level easily interfere with the detection of membrane fouling by the automatic membrane cleaning device, and in actual use, special personnel are still required to judge the cleaning requirements of the membrane on site, and then perform automatic cleaning operations, so the inconvenience of operation and maintenance has not been fundamentally solved The problem

Patent CN104843945A discloses a complete set of MBR sewage treatment equipment, which has a long process flow, large equipment volume, and not a fully integrated structure, which is not conducive to transportation and installation, and also causes inconvenience to operation and debugging
