Ammonia nitrogen remover
Ammonia nitrogen removal agent is white or gray powder granular solid with strong pungent smell. It is a high-tech product composed of a variety of inorganic compounds, chelating agents and additives. It is a new high-tech water treatment agent without secondary pollution.
In the process of treatment, it can give full play to the coordination functions of catalytic oxidation, flocculation, adsorption and co sedimentation to strengthen the treatment of sewage. This agent has a better effect on ammonia nitrogen treatment, and the production sludge is easier to be dehydrated, which can avoid or reduce sludge thickening, adjust the use of flocculant and reduce the cost of sewage sludge treatment.
Total phosphorus removal agent
Black powder is mainly used to remove total phosphorus in water such as inorganic phosphorus and solve eutrophication of water body. It is used in electroplating, circuit board, chemical industry, domestic sewage and other wastewater treatment. It has adsorption, bridging, coagulation, coprecipitation, network capture, replacement, ion exchange and other mechanisms, and has obvious advantages in the removal of heavy metal ions, COD, ammonia nitrogen, chroma, suspended solids and other aspects.
COD removal agent
This product has a variety of inorganic chemicals and a variety of additives made of high-tech products with strong oxidant, the appearance of white slightly yellow powder. It can not only break the coordination bond of chelating agent to metal ions, but also break the C-C, c-0, C-N and C-S bonds of the molecule itself, as well as cyanide. The agent is added into the sewage to generate CO2 and H20, which will not cause secondary pollution to the environment, so it belongs to the environmental protection water treatment agent. The dosage of reagent is less and the reaction speed is fast. The effect is good and the treatment cost is low.
Biochemical growth promoting agent
The growth promoting agent is a kind of product for biochemical system developed by Veolia company after many years of sewage treatment experience, combined with the actual environment, environmental protection requirements, and in the understanding of biotechnology. It uses rare earth mineral materials to strengthen microorganisms and water purification materials to develop a product for biochemical system.
It can improve the biomass of bacteria, strengthen the flora, coagulate the substances to be treated in the water, make the flora work quickly, and increase the treatment rate by times. It can make the system work at full load and overload without reducing the treatment effect.
Heavy metal capture agent
Heavy metal trappers, It can chelate with heavy metal ions, so it can react with Cu2 +, Cd2 +, Hg2 +, Pb2 +, Mn2 +, Ni2 +, Zn2 +, Cr3 + and other heavy metal ions in wastewater at room temperature and wide pH value range, and rapidly generate insoluble, low water content, easy to filter and remove flocculent precipitation in a short time, so as to achieve the purpose of removing heavy metal ions from water.
Gray solid. It is especially suitable for the treatment of wastewater containing heavy metal pollution produced by electroplating processing, circuit board manufacturing, hardware mechanical processing, electronic manufacturing and assembly industries.
This product is a cationic polymer which can decolorize, flocculate and degrade cod. This kind of molecular structure is conducive to the combination of acid dyes and direct dyes, which makes them unstable and settle down. Therefore, the decolorant has a good effect on decolorization and COD reduction of high concentration and high chroma dye wastewater. The cod removal rate is 50 ~ 90%, and the chroma removal rate is more than 95%.
Colorless transparent viscous liquid or white solid is mainly used for decolorization of high chroma wastewater from printing and dyeing plants, especially for acid and direct dye wastewater treatment, as well as for textile, pigment, ink, papermaking black liquor, oilfield drilling and other high chroma industrial wastewater.
Anionic polyacrylamide yx-302
Anionic polyacrylamide series products are water-soluble linear polymers synthesized with high degree of polymerization. They are soluble in water, almost insoluble in benzene, ether, lipids, acetone and other general solvents. The treatment effect is ideal for suspended particles, high concentration, positive charge, neutral or alkaline pH, electroplating wastewater, printing and dyeing wastewater, leather wastewater and so on.
Using anionic polyacrylamide as flocculant, it is better to combine cationic polyacrylamide with polluted river water.
Cationic polyacrylamide yx-303
Cationic polyacrylamide series products are linear polymer copolymerized by cationic monomer and polyacrylamide. It has good water solubility, can be dissolved in water in any proportion and insoluble in solvent. The pH value ranges from 1 to 14, showing the characteristics of high polymer electrolyte, which is suitable for negative charge and wastewater treatment.
For sludge dewatering:
According to the properties of sludge, the corresponding brand of the product can be selected. Before the sludge enters the pressure filtration, the sludge can be dewatered. During the dewatering, the flocs will be large, and the filter cloth will not stick. During the pressure filtration, the sludge cake will be thicker and the dehydration efficiency will be high. The moisture content of the sludge cake will be less than 80%.
For domestic sewage and wastewater treatment:
This product shows positive electricity in acid or alkaline medium, so that the suspended particles in the sewage with negative charge of the sewage flocculation sedimentation, clarification. For example, papermaking wastewater, municipal wastewater treatment plant wastewater, monosodium glutamate factory wastewater, sugar making wastewater, textile printing and dyeing wastewater are treated with cationic polyacrylamide, which generally carries negative charge.
It is used for the treatment of tap water with river water as water source
It has the advantages of less dosage, good effect and low cost, especially the composite use effect with inorganic flocculant is better.
Coagulation refers to the aggregation process of colloidal particles and micro suspended solids in water. The material that can flocculate and coagulate in the coagulation process is called coagulant. Coagulants are mainly used for the purification of drinking water and industrial wastewater, and the treatment of special water quality (such as oily wastewater, printing and dyeing wastewater, smelting wastewater, radioactive characteristics, toxic heavy metals such as Pb, Cr, and F-containing wastewater).
