Abstract

The invention discloses an efficient sewage treatment agent. The sewage treatment agent comprises, by weight, the following raw materials: 10-20 parts of polyaluminum chloride, 2-4 parts of an enzyme agent, 6-12 parts of humus, 3-5 parts of a demulsifier, 2-3 parts of a growth stimulant, 3-5 parts of a flotation agent, 4-7 parts of a biological nutrient, 1-2 parts of a bactericide, 3-6 parts of a corrosion and scale inhibitor, 0.5-1 part of soybean oligopeptide powder, 0.8-1.4 parts of sodium carboxymethyl cellulose, 1.2-1.8 parts of dodecyl methacrylate, 0.3 to 0.5 part of polyether modified polydimethylsiloxane, and 50 to 80 parts of water. The efficient sewage treatment agent is prepared by the steps of preparing a culture solution, mixing a plurality of raw materials and the like. The efficient sewage treatment agent has the advantages of being non-toxic, safe, environmentally friendly and the like, and the heavy metal ion removal rate can be effectively increased when the efficient sewage treatment agent is used for treating sewage.

Description

【Technical field】 [0001] The invention relates to the technical field of preparation of sewage treatment agents, in particular to an efficient sewage treatment agent and a preparation method thereof. 【Background technique】 [0002] Livestock and poultry manure is not only a valuable organic fertilizer resource, but also a serious source of pollution. If it is discharged into the environment without proper treatment, it will cause serious pollution to surface water, groundwater, soil and air, and endanger the health of livestock and poultry itself and human beings. There are also relatively high concentrations of oxytetracycline and sulfadiazine in the aquaculture wastewater. Studies have shown that long-term high-concentration antibiotic drug discharge may lead to the accumulation of such drug residues in environmental receptors such as water and soil around the farm, thereby affecting the ecological environment. Potential harm to the environment and human health. Effective ...
