The working principle of decolorization flocculants, the application range of decolorization floccul

The flocculation and precipitation method is to use inorganic flocculants (such as aluminum sulfate) and organic anionic flocculant polyacrylammonium (PAM) to prepare an aqueous solution and add it to the wastewater, which will produce a compressed electric double layer, so that the suspended particles in the wastewater lose stability, and the colloidal particles coagulate with each other to increase the particles and form flocs and alum flowers. After the floc grows to a certain volume, it will be separated from the aqueous phase and precipitated under the action of gravity, so as to remove a large amount of suspended solids in the wastewater, so as to achieve the effect of water treatment. In order to improve the separation effect, coagulants can be added in a timely and appropriate amount.

The treated sewage can basically meet the discharge standards in terms of color, chromium content, suspended solids content, etc., and can be discharged or used as reinjection water for artificial water injection and oil recovery.

High-efficiency decolorization flocculant is a new type of quaternary ammonium organic polymer flocculant that integrates decolorization, flocculation and COD removal, with the molecular formula (C4H8N5X) N. Its decolorization effect is significant (95% removal rate) and it also has a high removal rate for COD, SS, and BOD.

Efficient decolorization flocculant performance.

1. In water treatment, the high-efficiency decolorization flocculant has a wide range of application to the pH of the raw water, no suspended solids or sediment, will not block the dosing equipment and pipelines, and can be used for wastewater treatment to directly add the original solution, without secondary pollution.

2. The chromaticity, SS, COD and BOD removal rate of sewage is high, the floc density is large, soluble in water, and the sludge is less, and the treated wastewater can meet the national discharge standard.

How to use high-efficiency decolorizing flocculant.

1. The high-efficiency decolorization flocculant can be diluted by 10% to 50% with stock solution or water, and then directly added to the wastewater, and alum flowers appear after a few minutes of full stirring, and the colored substances in the colored wastewater are flocculated and precipitated from the water, and the separation is achieved with sedimentation or air flotation.

High-efficiency decolorization flocculant is mainly used for the decolorization treatment of high-color wastewater in dye factories, and is suitable for the treatment of soluble dye wastewater such as reactive, acidic and disperse dyes. It can also be used for decolorization treatment of textile, chemical, coking, papermaking, printing and dyeing, bleaching and dyeing, leather, municipal sewage, industrial sewage station and other wastewater. It can replace water, activated carbon, polyacrylamide and other agents.

1. Dilute 10% 50% with water, then add it directly to the wastewater, fully stir for a few minutes and then appear alum flowers, flocculate and precipitate the colored substances in the colored wastewater from the water skin loss, and combine them with sedimentation or air flotation to achieve separation.

2. When the color and COD of wastewater are high, this product can be used with inorganic flocculant to treat, but it can not be mixed, which can reduce the treatment cost. In this way, the cost of treatment can be reduced, and the order and proportion of the chemical input should be determined according to the actual combustion liquid.

3 The amount added is wastewater (depending on the concentration of wastewater).

Looking at the current situation of flocculants, it can be seen that there are many varieties of flocculants, from low molecular weight to high molecule, from single type to composite type, and the general trend is to develop in the direction of cheap, practical, non-toxic and efficient. Inorganic flocculants** are cheap, but can adversely affect human health and the ecological environment; Although the amount of organic polymer flocculant is small, the output of scum is small, the flocculation ability is strong, the floc is easy to separate, and the effect of oil removal and suspended solids is good, the residual monomer of this kind of polymer has the effect of "three causes" (causing sakiness, carcinogenesis, and mutagenicity), so its application scope is limited; Microbial flocculants are easy to use and have attractive application prospects due to the absence of secondary pollution. Microbial flocculants may replace or partially replace traditional inorganic and synthetic organic polymer flocculants in the future.

The development and application of microbial flocculants are in the ascendant, and their characteristics and advantages show a broad prospect for the development of water treatment technology.
