Problems solved by technology

[0004] The function of the sewage sedimentation tank is mainly to separate mud and water, and the conventional methods are free sedimentation, flocculation sedimentation, group sedimentation and compression sedimentation, but each sedimentation method has its own shortcomings, or the sedimentation time is too long, or mud water separation Incomplete, poor sedimentation

Abstract

The invention discloses an integrated sewage treatment system and an application method thereof. The integrated sewage treatment system comprises a water inlet, a pre-denitration pond, an anaerobic pond, an anoxic pond, an aerobic pond, a settling pond and a water outlet. According to the application method, firstly, a container is opened to make immobilized microorganism balls flow into the system, then the immobilized microorganism balls long in use time are collected, and lastly the collected immobilized microorganism balls are remade. The immobilized microorganism balls used in the integrated sewage treatment system and the application method of the integrated sewage treatment system not only can keep the activity of microorganisms and purify water but also can separate mud and water and is good in settling performance; the diameter of the immobilized microorganism balls is selected properly, and the immobilized microorganism balls can be suspended without a large magnetic field; under the action of the magnetic field, the immobilized microorganism balls can be in a suspended state, and the activity of the microorganisms can also be improved; the immobilized microorganism balls can be recycled, and therefore the microorganisms in the immobilized microorganism balls are always in a high-activity state.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an integrated 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 sedimentation 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 balls...
