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 an oxidation ditch sewage treatment system and a using method thereof. The system comprises a thick grating, a thin grating, an oxidation ditch and a membrane pool. The using method of the system comprises the steps that firstly, a container is opened, and immobilized microorganism balls flow into the system; then, the immobilized microorganism balls which are used for a long time are collected; finally, the collected immobilized microorganism balls are re-manufactured. The adopted immobilized microorganism balls in the oxidation ditch sewage treatment system and the using method thereof can maintain activity of microorganisms and separate mud from water, membrane holes cannot be blocked, and membrane pollution is lowered. Selection of diameters of the immobilized microorganism balls is just perfect, the immobilized microorganism balls can suspend without a large magnetic field, and sewage can make contact with the microorganisms in the immobilized microorganism balls. By means of the action of the magnetic field, the immobilized microorganism balls can be in a suspending state, and the activity of the microorganisms can be improved. The immobilized microorganism balls can be recycled, and therefore the microorganisms in the immobilized microorganism balls can be in a high-activity state all the time.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an oxidation ditch sewage treatment system and a use method thereof. 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] The oxidation ditch uses a continuous loop reaction tank as a biological reaction tank, and the mixed solution is continuously circulated in a closed aeration channel in the reaction tank. The oxidation ditch is usually used under the condit...
