Many Internet users in the advice about the problem of textile wastewater treatment equipment today small make up this site on the Internet to find an article about the relevant materials of textile wastewater treatment equipment, please follow look small make up for textile printing and dyeing wastewater treatment and reuse of generally includes three processes: the first step is to use common physicochemical and biochemical treatment process meet the discharging standard wastewater treatment, the second step is to meet the requirements of discharge wastewater deep treatment, 2) Biochemical treatment: use the carrier after domestication, hanging film composite membrane mud flow bed reactor ( The CBR reaction pool) In primary air floatation processed wastewater aerobic organic matter decomposition (3) Post-processing: clear liquid water on the tank into the secondary air flotation pool, by adjusting the reflux ratio of secondary air flotation pool and the abattoir wastewater treatment equipment dissolved air pressure, further remove the impurities in the waste water and suspended particulate matter and to reduce the effluent SS, then introduces wastewater pool ozone oxidation, through the strong oxidizing ozone, will be difficult to degradation of organic matter in the process for biological treatment of further degradation, as well as the use of ozone bleaching performance, guarantee the shade of the water, finally introduces ozone pool water recycling pool, realize the waste water reuse 1) This process is the existing mature wastewater biological treatment and physical and chemical treatment process, through the optimization of the parameters and biological carrier composite membrane reactor through the mud microbial screening and domestication, able to handle high pollutants concentration, high colority textile printing and dyeing wastewater, water quality is not stable, low operating cost, good treatment effect, stable operation, the advantages of simple operation, 2) This technology can effectively solve the problem of textile printing and dyeing enterprises wastewater reuse treatment, water reuse water quality meets the demand of printing and dyeing enterprises of water, can solve the contradiction between the textile printing and dyeing enterprise development and pollution emissions, achieve the energy conservation and emissions reduction targets of the enterprise, enterprise running textile wastewater treatment equipment to reduce costs, improve enterprise's competitive advantage, textile printing and dyeing wastewater treatment process equipment technology process on the basis of quality characteristics of printing and dyeing wastewater treatment project, using A/O process with dominant fungi wastewater treatment technology, process flow is: at the beginning of heavy oil pool - Adjust the pool - Hydrolysis acidification - Biological contact oxidation - Tank - Clear water reserviors - Back to guangzhou sewage treatment equipment with water system special waste water at the beginning of air flotation equipment machinery grille dyeing wastewater pool sinking separation tank regulation pool and cooling tower 1 # pool of surplus sludge hydrolysis acidification pool 2 # 3 # hydrolysis acidification hydrolysis acidification pool pool 2 # 1 # biological contact oxidation pond sludge biological contact oxidation pool pool inclined tube thickener backflow sludge pool clear water reserviors falls between the excess sludge sand pool area discharging standard mud cake sinotrans textile wastewater treatment equipment, sludge dewatering sludge concentration pool is set between 1 # ~ 3 # hydrolysis acidification pool, each 2, 1 # 9 mx4 ChanChi hydrolysis acidification pool size. 19mx9. 1 m, 3 hydraulic retention time. 6 h2 # 9 mx2 ChanChi hydrolysis acidification pool size. 83 mx7。 1 m, hydraulic retention time 2. 46h1.

Level 1 emission standard
