The agricultural wastewater has large water volume and wide influence range, and mainly comprises a physical treatment method, a chemical treatment method and a biological treatment method when the agricultural breeding wastewater with large concentration is treated. The chemical treatment method is a wastewater treatment method for separating and removing pollutants in a dissolved and colloidal state in wastewater or converting the pollutants into harmless substances through chemical reaction and mass transfer. In the chemical treatment method, the treatment units based on chemical reaction generated by adding medicaments are as follows: coagulation, neutralization, redox, and the like. Compared with other physical and chemical methods, the coagulating sedimentation process has the advantages of good effluent quality, stable and reliable process operation, economy, practicality, simple and convenient operation and the like. The principle of coagulating sedimentation is that by adding some medicaments (generally called coagulant and coagulant aid) into water, particles which are difficult to precipitate in the water can be polymerized with each other to form colloid, and then the colloid is combined with impurities in a water body to form larger floccule. The flocculating constituent has strong adsorption capacity, can adsorb suspended matters, and can adsorb partial bacteria and soluble substances. The flocs sink through adsorption and volume increase

At present, when the aquaculture wastewater is treated, the procedures of precipitation, transportation, coagulation, precipitation, neutralization, oxidation reduction and the like need to be carried out, the treatment process is relatively complex, the treatment speed is relatively slow, and particularly, the raw water needs to be precipitated for a long time, so that the wastewater treatment efficiency is low, and the precipitated sludge and excrement residues are in a fluid state and are difficult to transport for deep processing treatment.
