Many netizens in consulting about sewage treatment facilities in sichuan today small make up this site on the Internet to find four article about sichuan about the sewage treatment equipment related information, 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 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, to ensure the water color sichuan sewage treatment equipment, 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)
Biological contact oxidation, design calculation is designed according to the general sewage water quality, water quality by the BOD5 an average of 200 mg/L, the effluent BOD5 was 200 mg/L design consulting industry sewage into the equipment on Settings - 15063679196 weeks
Adjust pool, to adjust the sewage water quality, water quantity, effective retention time is commonly 4 to adjust the pool
8 hours, adjusting pool inlet grille area, large particles which in sewage of elam sundry to ensure normal operation of the pump (
Automatic grille: adjustment in the pool water from the pump to grid, grid is used to block in sewage wastewater treatment equipment in xinjiang small floater and suspended particles, block load down the dirt with the grille harrow automatically into the sewage pool, sewage into the subsequent process, the grating as equipment imported from Japan, has good separation effect,
Grid gap 5 mm to 10 mm)
In addition to dirt, difficult to jam, automatically the advantages of long service life,
Anaerobic pool, anoxic setting for denitrification process, after grille separation of sewage flow into the anaerobic pool and touch the reflow nitrifying liquid mixture, place NZP - lack of oxygen in the pool
11 type packing as A carrier of denitrifying bacteria, packing of nitrogen, phosphorus and sulphur whereabouts effect is good, stay for 2 hours with the combination of sludge in the process of renewal of pool forming method of A/O process, so as to achieve the aim of dephosphorization and denitrification,
