A method of treatment of industrial wastewater, coagulating sedimentation method coagulating sedimentation method using coagulant A method for purification of industrial waste water, waste water treatment coagulant added mainly by some special chemical constitution enables sewage harmful substances through a series of action and to purify. By this method, it can be used for treatment of drinking water, industrial water, mine drainage, oil field waste water, domestic water, water treatment and dyeing wastewater. Second, the biological degradation in the current industrial wastewater emissions, printing and papermaking wastewater discharge are the two main reason causing environmental pollution. Since many printing of fuel is composed of some aromatic compounds, the structure is more complex, difficult to degrade by chemical methods. The slightest mistake, may also lead to poisoning of water quality, which is why this type of discharge of sewage, industrial waste water process, the method is a better biodegradable. Third, the adsorption adsorption method is the use of adsorbents for wastewater treatment. Application of the industry is now more adsorbents magnesium hydroxide, activated carbon and new adsorbent cellulose - chitosan and its derivatives. By this method, it can be used to handle paper and printing and dyeing wastewater, urban sewage, wastewater, fluorine-containing wastewater. Fourth, the ion exchange resin ion exchange resin is a polymer material containing a synthetic functional reactive groups, in particular through the exchange of substances with sewage purification reached with switching, selection, adsorption and catalytic functions. Mainly used for industrial wastewater heavy metals and precious metals recovery, purification of toxic substances, pesticides industrial wastewater treatment works to remove the organic wastewater organic acidic or alkaline substances, industrial waste water treatment programs, such as phenol, acids and amines. Fifth, the membrane separation technology of membrane separation technology for oil by ultrafiltration membrane wastewater treatment, the grease removal rate of 97% -100%, mainly used in industrial production of various oily waste water treatment, waste water can handle catering, medicine chemical waste, dyes and wastewater. Guangzhou-Zhanjiang foreign students environmentally green sugar Wastewater: With the rapid development of industry, type and quantity of waste of the rapid increase in water pollution are becoming increasingly widespread and serious threat to human health and safety. Environmental experts believe that the protection of the environment, it is more important than industrial wastewater treatment of urban sewage treatment. Although industrial wastewater treatment has already begun in the 19th century, and in the subsequent half century a lot of experimental research and production practice, but because many industrial wastewater are complicated, changeable nature, there are still some technical issues not fully resolved . This technology has matured and urban sewage treatment is different. Composition and properties of complex industrial wastewater, treatment is difficult, big cost, comprehensive prevention and control measures must be used. The most fundamental measure is to replace toxic materials with non-toxic materials, in order to eliminate the production of toxic waste. In the use of toxic materials in the production process, using a reasonable process and equipment, eliminating escape, in order to reduce consumption and Loss toxic materials. Heavy metal waste, radioactive waste, waste water and inorganic toxicants poorly biodegradable organic poisons wastewater, Putian industrial waste, and other waste diversion as far as possible, on the spot alone, and to maximize the use of closed-loop system, or in the factory proper pretreatment, and then discharged into the sewer to meet emission standards. Relatively clean water, such as cooling water, preferably recycled to the plant after simple treatment, in order to save water resources, sewerage and sewage treatment plants to reduce the load. Properties similar to urban wastewater effluent can be discharged into the sewer, we focus on the sewage treatment plant. Some biodegradable toxic waste such as phenol, cyanide wastewater discharge standards can be discharged into the city sewer and urban sewage mixing process.
