Abstract

The invention provides a black and odorous water body treatment agent. The black and odorous water body treatment agent comprises an early-stage reaction reagent and a later-stage coagulant aid, and is characterized in that chemical components in the early-stage reaction reagent comprise calcium oxide, Fe powder (a mineral substance) and silica; the early-stage reaction reagent is prepared from the chemical components in parts by mass: 20 to 40 parts of the calcium oxide, 10 to 30 parts of the Fe powder (the mineral substance) and 5 to 25 parts of the silica; chemical components in the later-stage coagulant aid comprise SiO2, CaCO3 and PAM (Polyacrylamide); the later-stage coagulant aid is prepared from the chemical components in parts by mass: 5 to 25 parts of the SiO2, 15 to 35 parts ofthe CaCO3 and 0.5 to 2.5 parts of the PAM. Compared with an existing treatment method, after the reagent is added, pH regulation before treatment and the reagent are carried out at the same time; thetreatment method has the characteristics of shortened flow, convenience for operation, consumption reduction and the like and can be adaptive to treatment requirements of different black and odorous water bodies.

Description

technical field [0001] The present invention relates to black and odorous river bottom mud-water body restoration, microbial carrier construction, in-situ treatment, etc., specifically a method for realizing efficient black and odorous water redox potential enhancement, bottom mud volume reduction, and black and odorous water body and sludge treatment A comprehensive treatment agent, using microbial carriers to construct natural minerals for black and odorous water and sludge treatment. Background technique [0002] At present, the treatment of black and odorous sediment-water body adopts to adjust the pH value of black and odorous water first, and then add Fe 2+ , and finally add hydrogen peroxide to react, the pH value of the reaction condition is 3-3.5, and finally adjust the pH to meet the national standard discharge requirements. In the process of use, there are disadvantages such as long process flow, many control points, difficult control, large consumption of acid, ...
