Abstract

The invention relates to a wastewater biochemical treatment activated sludge conditioner and a preparation method thereof. The wastewater biochemical treatment activated sludge conditioner is prepared from the following raw materials: molasses, a nitrogen source, ammonium sulphate, magnesium sulfate heptahydrate, saccharomycete fluid, glucanase, protease, poly-ferric aluminium sulphate and water. The preparation method of the wastewater biochemical treatment activated sludge conditioner comprises the following steps: firstly fermenting by utilizing the nutrient substances, culturing saccharomycetes in the saccharomycete fluid, then digesting by virtue of the glucanase and protease, and adding poly-ferric aluminium sulphate, so that the wastewater biochemical treatment activated sludge conditioner is obtained. The prepared wastewater biochemical treatment activated sludge conditioner has the advantages that proliferation of microorganisms in activated sludge can be quickly stimulated, and activated sludge treatment efficiency is improved; an impacted or filamentously expanded biochemical system can restore 7-15 earlier if the conditioner is used, effluent parameters are obviously better than those of a biochemical system without the conditioner, and usage amount of the conditioner is low, cost is low, and microorganism growth can be obviously promoted.

Description

technical field [0001] The invention relates to an activated sludge conditioner for wastewater biochemical treatment and a preparation method thereof, belonging to the technical field of wastewater biological treatment. Background technique [0002] The activated sludge method is currently the most widely used treatment method in the field of wastewater biochemical treatment. It uses activated sludge as the main body to treat wastewater. Aerobic microorganisms reproduce in large numbers after the air is introduced, and the produced extracellular enzymes aggregate to form bacterial micelles, and a large number of bacterial micelles combine to form activated sludge. The microorganisms in the bacterial micelles can transfer pollutants in wastewater, Transformation and purification, so as to achieve the purpose of biochemical treatment of wastewater. Compared with other methods, the activated sludge method has the advantages of wide application range, low investment, low operat...
