Sewage treatment equipment and sewage treatment method applying the same

Abstract

The invention relates to sewage treatment equipment and a sewage treatment method applying the same, and belongs to the technical field of sewage treatment. An anoxic area, an aerobic area, a membranepool area and an equipment area are sequentially arranged in the equipment, wherein a denitrification system is arranged between the anoxic area and the aerobic area; an MBR (membrane bioreactor)module is arranged in the membrane pool area; a phosphorus removal system, an aeration pipeline system, a suction disinfection system and a cleaning system are arranged in the equipment area. The sewage treatment method comprises the steps as follows: driving the phosphorus removal system, the aeration pipeline system and the suction disinfection system to work; removing AN, TN and TP pollutants fromthe sewage, treating the sewage with an MBR process, and disinfecting and discharging the sewage; controlling the cleaning system to work according to outflow pressure difference of the sewage. The sewage treatment equipment and the sewage treatment method have the beneficial effects that the sewage treatment equipment has reasonable and attractive structural design and is convenient to transport,and the sewage treatment method applying the equipment has the advantages that effluent quality is higher and more stable, energy is saved, consumption is reduced, secondary pollution is greatly reduced, automatic monitoring and operation efficiency is high, and integration of resource utilization is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment equipment and a sewage treatment method using the equipment. Background technique [0002] According to relevant statistics, my country currently has more than 600,000 administrative villages and more than 2.5 million natural villages, where more than 200 million peasant households and nearly 800 million people live. At present, more than 600 million people in rural areas across the country have basically achieved safe drinking water, but the drainage situation in rural areas is not optimistic. About 96% of the villages do not have drainage channels and sewage treatment systems. Sewers flow into rivers, etc. Due to factors such as the level of economic development and living habits in rural areas, the pollution factors in sewage, especially plant nutrients such as nitrogen and phosphorus, are relatively high, which is likely to cause eutrophication of ...
