Problems solved by technology

[0004] In the process of membrane process wastewater treatment, sludge often adheres to the membrane modules, causing the membrane pores of the membrane modules to be blocked by sludge, resulting in a decrease in water purification efficiency. Therefore, enterprises need to spend a lot of time and money on membrane pollution every year. cleaning

Abstract

The invention discloses a suspended microbial sewage treatment system and its operation method, comprising a water inlet, a pre-denitration tank, an anaerobic tank, an anoxic tank, an aerobic tank, a membrane tank and a water outlet; the operation method is as follows: first open the container, Make the immobilized microbial balls flow into the system, then collect the immobilized microbial balls that have been used for a long time, and finally remake the collected immobilized microbial balls; Immobilized microbial balls can not only maintain the activity of microorganisms, purify water quality, but also separate mud and water without blocking the membrane pores and reduce membrane pollution; the diameter of the immobilized microbial balls is just right; the effect of the magnetic field can make the immobilized microbial balls in Suspended state can also improve microbial activity; immobilized microbial balls can be recycled, so that the microorganisms in the immobilized microbial balls are always in a high activity state.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a suspended microbial sewage treatment system. Background technique [0002] my country is a country with extremely unbalanced distribution of water resources. The water resources in various places are very uneven. It is generally a water-scarce country. 70% of the cities in the country are in a state of water shortage. At the same time, my country is also a country with serious water pollution. , The loss caused by water pollution accounts for about 2% of GDP every year, and the water pollution situation continues to aggravate, making the sewage treatment and regeneration industry receive unprecedented attention. [0003] A part of the immobilized microbial balls in the pre-denitrification tank is returned from the membrane tank. The pre-denitrative tank is used to remove the nitrate carried in the immobilized microbial balls, so that the efficiency of the immobilized microbial ba...
