Continuous alternating MBBR sewage treatment method and equipment

Abstract

The invention provides a continuous alternating MBBR sewage treatment method and equipment. The treatment method comprises the following steps: suspended granular impurities in sewage are removed by pretreatment, quality and quantity equilibrium treatment is performed on the sewage, then anaerobic phosphorus release and synchronous denitrification and nitrification treatment are performed on the sewage by adopting anaerobic / anoxic / aerobic alternating operation, and pollutant matrix removal efficiency is improved. The treatment equipment comprises a homogenization chamber, a facultative chamber, a transition chamber, a pre-denitrification chamber, an aerobic tank, an efficient sedimentation tank and an equipment control chamber which are communicated through a water pipeline, wherein ultraviolet disinfection equipment, a pipeline booster pump, a full-automatic filtering tank, an aeration fan and a PLC control device are arranged in the equipment control chamber. The treatment equipmentis high in integration degree and functionality and simple and convenient to mount and operate, occupies small area and has high space utilization rate, long-term operation stability of the equipmentis enhanced, and treatment energy consumption and operation and maintenance cost of the whole sewage treatment equipment are reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a continuous alternating MBBR sewage treatment method and equipment. Background technique [0002] With the increasing pollution of water environment, the problem of water environment pollution has become a hot spot in the field of environmental protection at home and abroad. In view of the dispersion, extensiveness and uncertainty of water quality and quantity of sewage in small cities and towns in my country, the traditional sewage treatment process has been far away from the multi-functionality of pollutant removal, high efficiency and stability, convenient operation and economic rationality. Therefore, it is necessary to develop, research and apply new sewage treatment processes and technologies, and seek one or more advanced sewage treatment technologies with high efficiency, low consumption, convenient operation, low investment cost and low operation and maintenance...
