Abstract

The invention discloses a two-stage sewage treatment system and a use method thereof, comprising a water inlet, an aeration tank a, a sedimentation tank a, an aeration tank b, a sedimentation tank b and a water outlet; the use method is as follows: firstly, the sewage Enter the described two-stage sewage treatment system through the water inlet, then open the container, let the immobilized microbial balls flow into the required sewage treatment system, and finally collect the immobilized microbial balls and remake them; The immobilized microbial balls used in the segmental sewage treatment system and its use method can not only maintain the activity of microorganisms, purify water quality, but also separate mud and water, and have good settling properties; the diameter of the immobilized microbial balls is just right; the effect of the magnetic field can Making the immobilized microbial balls in a suspended state can also improve the microbial activity; the 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 two-stage sewage treatment system and its use method. 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 two-stage sewage treatment system is divided into two sections. The first section is the adsorption section, which is mainly based on bioflocculation adsorption, and incomplete oxidation reaction occurs at the same time. The second section is the bio...
