Problems solved by technology

Inorganic flocculants are cheap and economical, but compared with organic polymer flocculants, they are inferior in polymerization degree and flocculation effect
Organic polymer flocculants have the advantages of less dosage, fast flocculation speed, and little influence on pH value and temperature, but they are more expensive

preparation example Construction

[0046] The preparation method of medicament of the present invention:

[0047] Add water first, and then add the medicament in proportion (there is no sequence for adding the medicament), and stir the whole process.

[0048] The flocculation of inorganic salt flocculants is closely related to the hydrolysis process after addition. When the inorganic salt flocculant is added into the water, the metal ions in it will undergo a series of complex hydrolysis reactions, and the intermediate products produced during the hydrolysis process can form polymers with different anions and negative electrosols in the water, that is, polymer flocculation. eventually settled down.

[0049] Compared with existing medicaments, the present invention has the following advantages and effects:

[0050] The composite flocculant is composed of a water-soluble polymer flocculant and an inorganic salt flocculant. It uses the high positive charge density of the inorganic flocculant and the bridging eff...

Abstract

The invention provides a composite type desulfurized waste water flocculant. The flocculant is a compound of water soluble polymeric compound flocculant and inorganic salt flocculant. The flocculant mainly comprises polyacrylamide, polyamine salt, polyaluminum iron, surfactant and water. The flocculant can effectively remove the indexes such as suspended substance and COD in the waste water, and can be widely applied in the industrial sectors such as water treatment, paper making, petroleum, coal, metallurgy, geology, textile and building. Moreover, the flocculant is also suitable to the fields such as special industrial waste water and coal floating sludge washing and dewatering. The agent is a light yellow liquid free of odor, taste, toxicity and color, the pH value (1% aqueous solution) is no lower than 3.0, the density (20 DEG C) is no lower than 1.01g / cm3, and the limited content is no smaller than 1.0%.

Description

technical field [0001] The invention relates to a desulfurization wastewater treatment agent, in particular to a composite desulfurization wastewater flocculant. Background technique [0002] In general desulfurization wastewater, suspended solids and COD are the main removal objects. The conventional chemical method that can effectively remove suspended solids and COD is flocculation and sedimentation. This method uses the interaction of suspended colloids and dispersed particles to generate flocs under the interaction of molecular forces after adding flocculants, and collides and coagulates with each other during the settling process. , and eventually settle down to achieve the purpose of removing suspended matter and COD. [0003] Flocculants are mainly divided into two categories: inorganic flocculants and organic flocculants. As a kind of inorganic flocculants, inorganic salt flocculants can use the intermediate products produced in the process of hydrolysis to form ...
