Immobilized microorganisms for sewage treatment as well as preparation method and application of immobilized microorganisms

The present application discloses immobilized microorganisms for sewage treatment. The immobilized microorganisms include functional microorganisms and immobilized carrier chitosan, wherein the functional microorganisms are simultaneous nitrification and denitrification bacteria, and the immobilized carrier chitosan is a biopolymer obtained by deacetylation of chitin. The invention also disclosesa preparation method and application of the above immobilized microorganisms for sewage treatment. According to the method, the functional microorganisms and the immobilized carrier are mixed to formsolid microbial bacteria pellets, wherein the immobilized carrier chitosan can be used as an adsorbent to adsorb nitrogen, phosphorus and other elements in sewage, and the functional microorganisms has an excellent removal effect on nitrogen in the sewage. When the immobilized microorganisms are used, the immobilized microorganisms can be put into a sewage treatment facility, so that the operationis simple. 本申请公开了一种用于污水处理的
