Abstract

The invention discloses a domestic sewage treatment agent and a preparation method thereof, belonging to the field of sewage treatment. The method includes the following steps: (1) drying and dehydrating the activated sludge; (2) mixing the dried and dehydrated activated sludge, boronite calcium carbonate, and sodium bentonite, putting them into a low-temperature pulverizer for pulverization, and 150 (3) Soak chitin-modified plant fiber and cellulase in bamboo vinegar solution for 1-2 hours, freeze-dry to constant weight, and set aside; (4) Mix the mixed powder, polysilicic acid Add aluminum, calcium chloride, calcium lignosulfonate, aluminum chloride, ferric chloride, sodium acetate, acetyl lanolin, glyceryl monostearate, and potato powder into water and mix well; (5) add sodium alginate , Dry at 130-150°C, grind again, and cool. Each component in the domestic sewage treatment agent of the invention interacts and cooperates with each other, so that the effect of sewage treatment is greatly improved.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a domestic sewage treatment agent and a preparation method thereof. Background technique [0002] In order to discharge or reuse wastewater after treatment, a variety of chemicals need to be used in the treatment process. Depending on the purpose, these agents can be divided into the following categories: [0003] ⑴Flocculant: Sometimes also called coagulant, it can be used as a means to strengthen solid-liquid separation, used in primary settling tank, secondary settling tank, flotation tank, tertiary treatment or advanced treatment and other process links. [0004] ⑵ Coagulant: Auxiliary flocculant plays a role to enhance the coagulation effect. [0005] (3) Conditioning agent: also known as dehydrating agent, used to condition the excess sludge before dehydration, and its varieties include some of the above-mentioned flocculants and coagulants. [0006] (4) Demulsifier: So...
