Abstract

The invention discloses a microbial coagulant for municipal wastewater, and relates to the technical field of wastewater treatment. The microbial coagulant is prepared from 15-25 parts of polymerization ferric chloride, 10-20 parts of sodium aluminate, 6-8 parts of sodium carboxymethyl starch, 3-6 parts of sodium silicate, 20-30 parts of nano-montmorillonite, 2-6 parts of activated carbon, 15-25 parts of iron residues, 12-24 parts of bentonite, 12-24 parts of sepiolite powder, 6-8 parts of sodium gluconate, 15-25 parts of potato starch, 10-20 parts of cellulose, 6-8 parts of protease, 3-5 parts of amino acid and 100-120 parts of deionized water. The microbial coagulant for the municipal wastewater and a preparation method thereof have the advantages that the technological process is simple, the raw material ratio is reasonable, and the raw materials are low in cost and easy to obtain; microorganisms are added, a large number of organic elements and inorganic elements are matched, therefore, the microbial coagulant is applied to domestication of microorganism in the domestic wastewater and adjustment of microorganism death caused by insufficient nutrition components or the imbalanced ratio, and the microbial coagulant is low in cost, easy to obtain, free of pollution and rich in nutrition components.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a microbial coagulant for urban sewage and a preparation method thereof. Background technique [0002] In recent years, the number and population of cities and towns in my country have grown rapidly. Due to the lagging development of environmental planning and environmental protection in many central towns or small market towns, water pollution and eutrophication in surrounding areas have become increasingly prominent. Small towns in many regions discharge untreated sewage arbitrarily, which not only pollutes large areas of water, but also reduces the use value of water. Since the sewage discharge points in small towns are scattered and difficult to be treated in a centralized manner, a combination of centralized treatment and decentralized treatment is mainly used. In addition, due to economic reasons, small towns can only adopt process technologies and devices that have lo...
