Problems solved by technology

[0003] In the process of sewage treatment by membrane technology, 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, companies need to spend a lot of time and money on membrane pollution every year. cleaning

Abstract

The invention discloses a method for preparing and recovering immobilized microbial balls used in water treatment of membrane modules. The immobilized microbial balls include magnetic media and activated sludge; the preparation and recovery methods are as follows: the activated sludge is placed on the plate In the round hole, put the magnetic medium in the activated sludge in the round hole. After air-drying, the immobilized microbial balls can be obtained. The immobilized microbial balls are used in the water treatment of the membrane module and recovered after a period of use. The magnetic medium is recovered by soaking, rolling, and centrifugation; then the magnetic medium and activated sludge are remade into immobilized microbial balls; immobilized microbial balls can not only maintain the activity of microorganisms, purify water quality, but also separate mud and water , to reduce membrane fouling; the selection of the diameter of the immobilized microbial balls is just right; the action of the magnetic field can make the immobilized microbial balls in a suspended state; the immobilized microbial balls can be recycled, so that the microorganisms in the immobilized microbial balls are always in a highly active state.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a method for preparing and recovering immobilized microbial balls used in water treatment with membrane modules. 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] In the process of sewage treatment by membrane technology, sludge often adheres to the membrane modules, causing the membrane pores of the membrane modules to be blocked by sludge, resulting in a d...
