When industrial wastewater discharge may both urban drainage channels, there may direct discharge of water, a decision should be compared through the program, in general, is often more desirable is a comprehensive program that processed and sent to the city treatment plant combined. Some waste can be recycled materials or production byproducts, when some wastewater treatment technology alone is simple, low cost, then the recovery or disposal in the factory or workshop, or even organize the production process to be reasonable. The reduction in printing and dyeing wastewater oxygen consumption of industrial wastewater treatment, industrial wastewater and domestic sewage to make the combined treatment is generally more economical. Meanwhile, moderate focus easier than widely distributed processing management, easy to ensure the treatment effect. As for the toxic and hazardous substances, heavy metals removal and biological degradation of harmful organic substances is not easy, and only in the production of industrial waste site immediately resolved, let them waste factory, is a reliable way to prevent environmental pollution. 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, the development trend of industrial wastewater treatment are: water and pollutants as a useful resource recovery the use and implementation of closed loop. 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 technology to treat industrial wastewater, 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.
