Our research and development of water purifier has been switched on treated sewage farms, farm sewage, coal mine tunnel sewage, pig slaughterhouse wastewater, sorghum distillers brewery wastewater, textile wastewater, recycled paper mill wastewater and urban sewage suspended solids content of the sewage plant also successfully used in ceramics, ceramic tile plant effluent, marble polishing mill effluent, sewage washing, coal-fired boiler water wet dust, quartz sand sand sewage; and so contains a lot of organic pollutants in water and ammonia high water purification and reuse. Authority over the inspection department tested water purifiers related data influent and effluent. Test report card showed: ammonia removal can reach 85%, total nitrogen removal rate was 95%, organic nitrogen removal rate was 96%, BOD removal efficiency of up to 95% of sewage treatment, suspended solids removal efficiency is as high as 98.3 % ~ 99.6%, turbidity reached 300 degrees (3 mg / L) or less. This is the index of the water purification system in the context of low investment, low operating costs obtained. Sewage treatment nitrification and denitrification process factors: biological nitrogen removal in wastewater treatment, the denitrifying bacteria, denitrifying bacteria play an important role in the biodegradation process for these bacteria have certain environmental conditions: 1) DO: sewage hypoxia-treated structures, optimal DO denitrification of 0.5mg / L or less, in the aerobic structures in aerobic metabolism of organic matter, nitrification bacteria will NH4 + -N oxidized NHx - N, need oxygen Food plant waste water processing method, DO should be controlled at 2mg / L or more. DO change can significantly affect the system and the amount of denitrifying bacteria indicative of changes in the number of microorganisms. When a mixture of low DO concentration pharmacy wastewater treatment, indicative of microbial nitrification process of a small number of poor nitrification nitrogen; on the contrary in wastewater treatment, the more the number of indicator organisms, nitrification rate of nitrogen also increases. However, due to the high concentration of dissolved oxygen on nitrification bacteria have a certain extent, so DO control in general greater than 2mg / L conditions of low appropriate.
