Problems solved by technology

[0004] Polymer flocculants, such as basic polymeric alumina, polyaluminum sulfate, and polyferric sulfate, overcome the disadvantages of low-molecular-weight flocculants, but their cost is high, and the treatment effect is poor at low temperature and low turbidity
Organic flocculants are generally high molecular polymers, such as polyamine flocculants, quaternary ammonium starch-based flocculants and polyacrylamide flocculants, among which polyacrylamide has the advantages of less dosage, strong ability to clarify water quality, fast flocculation speed, It is not easily affected by the pH value of the water, and the amount of generated sludge is small, which has been widely used.

Abstract

The invention belongs to the technical field of flocculants, and particularly relates to an industrial wastewater flocculant and a preparation method thereof. The flocculant is prepared from the following components in parts by mass: 25 to 30 parts of sodium polyacrylate, 7 to 12 parts of activated silicic acid, 15 to 20 parts of polysilicate aluminum ferric sulfate, 7 to 12 parts of aluminum sulfate, 3 to 5 parts of dodecyl dimethyl benzyl ammonium chloride, 10 to 13 parts of sodium carboxymethyl cellulose, 2 to 4 parts of tetravinyl pentylamine, 6 to 10 parts of sodium pyrosulfite, 10 to 12 parts of sodium diethyldithiocarbamate trihydrate and 2 to 3 parts of polyvinyl alcohol. The industrial wastewater flocculant disclosed by the invention is short in settling time, wide in application range, good in stability and capable of effectively degrading heavy metal ions and organic matters in industrial wastewater, the particle size of a flocculating constituent is increased while fine flocculating particles are connected, the flocculating constituent is more completely settled, and the water absorption rate of the agglomerated flocculating constituent can be reduced.

Description

Technical field [0001] The present invention belongs to the field of flocculant, and in particular, there is an industrial wastewater flocculant and a preparation method thereof. Background technique [0002] Flocculation is one of the most common key links in industrial wastewater treatment processes. It has largely influences the operating conditions of subsequent processes, and finally the quality and cost fees, thus become important science and technology research and development in environmental engineering. The efficient flocculating technology system should be composed of excellent flocculants, reactors, and self-controlled drugs, and the flocculant starts. The key to flocculation technology is to select a suitable flocculant. [0003] The flocculant can be divided into inorganic flocculant and organic flocculant in accordance with its chemical composition. The inorganic flocculant further includes an inorganic coagulant and an inorganic polymer flocculation agent; an orga...
