Sewage treatment Jiangxi humic acid sodium humic acid sodium humate suppliers

Sewage sodium humic acid sodium humate a main ingredient, heavy metal ions in wastewater heavy metal ions from wastewater is a great harm to the ecological environment of the industrial waste, heavy metals into the environment involved in the food chain a direct threat to human health, brought about serious consequences. Currently containing heavy metal ions Pb2 +, Cu2 +, Cr3 +, Cd2 + and other wastewater treatment methods are mainly divided into two categories: one is the solution of the metal ions into insoluble substances, such as chemical precipitation, electrolytic reduction process; the other is not condensation under the separation of metal ions change the chemical form of the condition, such as ion exchange and exchange fiber method. Higher costs for treating wastewater. The low price of humic acid, which contains hydroxyl, carboxyl, quinone group and other active groups, ion exchange occurs with heavy metals in water, and surface complexation adsorption of heavy metal ions with good removal rates were 97 % or more, and has a strong anti-Ca2 +, Mg2 + interference. After the adsorption of heavy metal ions, through the analysis desorption regeneration process can be recycled. Cadmium-containing waste water removal rate was 99.8%, reaching the national emission standards; and chromium waste water removal rate of 96.6%. Second, the process of dyeing wastewater decolorization of dye wastewater treatment is a problem. Humic acid as a cationic dye bleaching agent for treatment of cationic dyeing wastewater, regardless of how high chroma, bleaching agents filtered through peat layer, can achieve colorless and transparent, the bleaching effluent treatment can be recycled. Humic acid adsorbent can also dye the wastewater toxic cationic retarding agent (1227) and Sophie VS and other agents to remove more than 97%.陈仙利 of dyeing wastewater treatment with sodium humic acid research, experimental results show that high pollutant removal efficiency of dye, and low cost of the process, with a high purifying effect. Third, scale and corrosion inhibitor for some natural humic acid is mainly an aromatic hydroxy acids, the molecular weight of large, ion exchange, adsorption and complexation properties of good permeability and dispersion, and can effectively disperse metal oxides, metal surface chemically stable protective film, showing good scale, cleaning and corrosion resistance. The use of sodium humic acid and sulfonic acid group-containing copolymer for raw materials HA / P blend of water and CaCO3, Ca3 (PO4) 2 inhibition rate, Fe2O3 dispersion and corrosion resistance study found that this total blend with high scale, decentralized and corrosion performance and to avoid adverse effects due to the lack of phosphorus water treatment agent brought, with high practical value. Fourth, to deal with other industrial waste sewage Dephenol test Kapucin free formulation containing 45.22% humic acid, when added to water such preparations, humic into humic acid salt, can absorb water in the phenol. Saturated with phenolic precipitates in the form of humic acid salt is separated from the waste water out. Studies conducted in Japan is 2 ~ 3 mm of SiO2 and then coated with a phenolic resin-coated humic acid made oil sorbent for treatment of oily waste water, to the oil effect is very satisfactory. 5: 100 ratio containing humic acid and microbial soil pellets into slaughterhouses Wastewater (including BOD 14300mg / L, suspended solids 18900 mg / L and E. coli 24000mg / L), in three consecutive aeration tank The reaction, finally form a free E. coli, BOD and suspended solids is very low (respectively 65 and 19 mg / L) of the supernatant
