Embodiment Construction

[0020] A preparation method for degrading and purifying agent for livestock and poultry breeding wastewater, comprising the following steps:

[0021] (1) Mix and dissolve chitosan and cationic starch in 4% glacial acetic acid aqueous solution, heat up to 75°C, then add dimethyl diallyl ammonium chloride to it, react for 4 hours and cool to At room temperature, after washing with absolute ethanol for 3 times, suction filtration is dried to obtain modified grafted chitosan for subsequent use, wherein the mass ratio of chitosan, cationic starch, glacial acetic acid aqueous solution, and dimethyl diallyl ammonium chloride is 5 :2:42:0.2;

[0022] (2) Mix the modified grafted chitosan, polyacrylic acid and water in a mass ratio of 7:3:1 and place in a warm water bath at 28°C, and stop stirring after 5 hours to obtain an organic coating solution for use;

[0023] (3) Put the fly ash into the muffle furnace and calcinate at 800°C for 120 minutes, take it out, soak it in 4mol / L hydro...

Abstract

The invention discloses a preparation method of a wastewater degrading purifying agent for livestock and poultry farming. The purifying agent is prepared from chitosan, a soluble high polymer material, cationic starch, dimethyl diallyl ammonium chloride, pulverized fuel ash, chromic nitrate, cerous nitrate, aluminum oxide powder and other raw materials. A coating-type double-layer structure is adopted, on an outer layer, chitosan is combined with the water soluble high polymer material, adsorbing and degrading particles of an internal core need to be slowly released into a water body through organic layer pores in the outer layer, in this way, influences on the water body are small, and acting time is delayed; the pulverized fuel ash is used for being treated separately through acid and base and then serves as a substrate supported Cr-Ce compound oxidizing body, in this way, a degrading space is provided for organic pollution, and substances of types capable of being adsorbed and degraded by organic matter are substantially increased. The purifying agent as an effective degrading material is provided for kinds of large-quantity pollutants in the wastewater of livestock and poultryfarming, the method has the advantages of being easy to operate, high in degrading speed, long in maintenance period and others, remarkable social, economic and environmental benefits can be generated, and the purifying agent is widely applied to kinds of livestock and poultry farming enterprises.

Description

technical field [0001] The invention relates to the technical field of wastewater purification, in particular to a preparation method of a livestock and poultry breeding wastewater degradation and purification agent. Background technique [0002] With the development of economy and society, the livestock and poultry breeding industry has become the pillar industry of my country's agriculture and rural economy, and the pollution of livestock and poultry caused by it has become increasingly serious. Pollution from livestock and poultry farming has become the third largest source of pollution after industrial pollution and domestic pollution. Livestock and poultry breeding wastewater has the characteristics of high concentration of COD, SS, NH4+-N, TP and other pollutants, and low C / N. Wastewater with high COD and NH4+-N, direct aerobic treatment will greatly increase the cost of aeration, it is advisable to use anaerobic treatment first to reduce COD load, but the C / N of anae...
