Abstract

The invention discloses a preparation method and applications of an aquatic product sewage treatment agent. The preparation method comprises following steps: mussel shell is treated with a diluted acid solution, and then is subjected to high temperature treatment and grinding so as to obtain mussel shell powder; an organic modifying agent and aluminium chloride are dissolved with deionized water,roasted bentonite is added, and stirring, reaction, and grinding are carried out so as to obtain modified bentonite; the mussel shell powder, sodium alginate, polyferric chloride, polymeric aluminium,the modified bentonite, polyacrylamide, vegetable fiber, and ethylene glycol-bis-(2-aminoethylether)-N,N, N', N'-tetraacetic acid (EGTA) are uniformly mixed, are subjected to pelletizing moulding ina pelletizer, and are dried so as to obtain the aquatic product sewage treatment agent. The beneficial effects are that: the advantages of the ingredients are achieved, synergetic effects are achieved, nitrogen, phosphor, and organic pollutants can be removed effectively, the aquatic product sewage treatment agent can be recycled, and can be used for aquatic product sewage treatment, the treatmenttechnology is simple, the operationality is high, efficiency is high, and no side effect on operation personnel is caused .

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to the preparation and application of an aquatic product sewage treatment agent. Background technique [0002] The aquatic product processing industry is an important part of my country's current food industry. With the rapid development of my country's economy and the continuous improvement of people's living standards, and the impact of international market demand, the demand for aquatic products is increasing day by day, and aquatic product processing enterprises are also following A large number of them have emerged, and the output of various processed aquatic products has been increasing year by year. However, due to the limitations of my country's current aquatic product processing and production technology level, the pollution problems in this industry are relatively serious, and the water pollution problem is the most prominent. Aquatic product processing wa...
