Embodiment Construction

[0024] Take the actual manufacturing process of preparing 180kg "composite high-efficiency flocculant" as an example

[0025] 1., at first, according to the mass fraction of batching component of the present invention, after fully considering influence factors such as raw material process consumption and evaporative drying dehydration, calculate the batching quantity of all group materials of producing 180kg " compound high-efficiency flocculant ".

[0026] The optimum mass parts of various components designed by the present invention are: 75 parts of polyacrylamide; 8 parts of acrylic acid; 6 parts of ethyl acrylate; 6 parts of hydroxyethyl cellulose; 3 parts of ferrous sulfate; 2 parts of aluminum sulfate. According to practical experience, the process loss of raw materials in the production process is about 5-6%. According to this, to produce 180kg of "composite high-efficiency flocculant", the total weight of various components that need to be mixed should be 190kg. Accor...

Abstract

The invention relates to a compound high-efficiency flocculating agent used for seriously polluted water. The flocculating agent takes water soluble polymer polyacrylamide as main materials, takes water soluble polymer acrylic acid, hydroxyethyl cellulose and ethyl acrylate as active coagulant aid, takes ferrous sulphate and aluminium sulphate of inorganic salts as catalyzing flocculating agent, uses the configured universal chemical industrial production equipment and adopts the technique processing technologies of metering blending, synthetic reaction, stabile concentration, vacuum hydrolysis and spray drying and the like; and a compound high-efficiency flocculating agent with high polymerization degree, high relative molecular quality, low use amount and simple use method is developed. Due to the unique molecular structure and chemical function, the compound high-efficiency flocculating agent has stronger absorption and flocculating effect to fine particles in seriously polluted water, can absorb the fine particles containing various inorganic substances and difficult degradable organic substances in the seriously polluted water and flocculate the fine particles into floccules, and can realize the purpose of improving and purifying the water quality after the flocculating groups are removed. The flocculating agent is especially applicable to the industrial wastewater treatment of seriously polluted enterprises of paper-making, printing and dyeing, leather-making, electroplating, food and chemical engineering and the like.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a compound high-efficiency flocculant which uses artificially synthesized polymers to absorb fine particles in flocculated sewage. Background technique [0002] With the rapid development of industrialization and urbanization in our country, especially the rapid growth of national economic construction for many years, the output of domestic sewage and industrial wastewater is also increasing. The sewage produced by these products contains a variety of toxic and harmful substances, polluting water quality, polluting the environment, and endangering human health; especially in papermaking, tanning, printing and dyeing, electroplating, food, chemical and other heavy polluting enterprises, the degree of harm of industrial wastewater discharged more serious. Smelting sewage and protecting the environment have become important responsibilities of governments at all levels. ...
