The basic way to control industrial wastewater sources: (1) reduce the amount of waste water discharge: wastewater diversion; water conservation; reform the production process; avoid intermittent discharge of industrial wastewater. (2) reduce the concentration of pollutants in waste water: reform the production process, to maximize the use of technology does not produce pollutants; improve the structure and performance of the device; wastewater diversion; both wastewater and; recovery of useful substances; discharge control system. (Wastewater concentration exceeds the stop) after wastewater treatment wastewater discharge standard three to go: into the water, re-use, irrigation. (1) National Standard: "Integrated Wastewater Discharge Standard; GB8978-1996 Scope: for environmental impact assessment of water pollutant discharge management of existing units, as well as construction projects, the construction project completion and acceptance of environmental protection facilities design and put into operation emissions management. In accordance with the national emission standards and national emission standards for the industry but also the implementation of the principle of non-cross-industrial wastewater treatment technology, in addition to the following industrial water outside the electroplating wastewater treatment, other water pollutants are the implementation of this standard. New national industry water pollutant discharge standard industry, according to the scope of the implementation of the relevant national industry standards for water pollutants, no implementation of this standard. Guangzhou, Dongguan, southern environmentally rich students papermaking wastewater projects: the development trend of industrial waste water treatment works in the growing shortage of water and other resources and environmental pollution increasingly urgent situation of industrial wastewater, industrial wastewater treatment development trends are: water and pollutants as a useful resources and implementation of closed loop recycling. It can be divided into water and contaminants combined cycle reuse. Water and contaminants each individual loop recycling. Industrial waste water treatment works in heavy metal wastewater treatment works mainly from heavy metal wastewater mining, smelting, electrolysis, electroplating, pesticides, pharmaceuticals, paints, pigments and other businesses discharge wastewater. Without heavy metal wastewater treatment, will seriously pollute the environment. Heavy metals in waste water treatment type, content and speciation varies with different manufacturers. In addition to heavy metals in wastewater treatment is very important. Because heavy metals can not break down the destruction, but their presence can only transfer the position and change their physical and chemical form, purpose except heavy metal. For example, the wastewater treatment process industrial wastewater treatment and reuse, after chemical precipitation treatment, wastewater from the dissolved ions of heavy metals into the insoluble form of sets of objects and settle down, transferred from the water to the sludge; by ion exchange treatment After the heavy metal ions in wastewater transferred to the ion exchange resin, and then from the regenerated ion exchange regeneration waste liquid is transferred to the resin.
