Pickling phosphating wastewater treatment equipment


GFPW series of steel structure integration pickling phosphating wastewater treatment equipment used in pickling wastewater treatment equipment, pickling phosphating wastewater treatment equipment, aluminum oxide acid sewage wastewater treatment equipment, etc.
process description  
      Waste water first to adjust the adjustment of the water, the water quality in the pool for sewage into the equipment before the PH value is greater than 5, after adjusting ChiJunHe wastewater by improve pump into the integration of the processing equipment, lift pump liquid level controller, automatic control, start the high water level range, the water level limit stop. Each part of the host mixing system and sewage pump linkage.  
      Integrated device contains more than one processing area, after classifying dosing for processing in all areas. First of all, in the area of the first wastewater with NaOH, using pH meter automatic control the dosage of add, through mixing machine mixing reaction, the pH control between 8 to 10, then adding the flocculant PAC, PAC addition amount is controlled by a metering pump manually add, remove heavy metal ions. Heavy metal ion precipitation after completely open the discharge valve to the sludge to the sludge pool.
    Residual gravity flow into the second area sewage wastewater with NaOH, using a pH meter automatic control the dosage of add, through mixing machine mixing reaction, the pH adjustment between 10 to 11, adding the CaCl2, fully mixing after dosing PAC, PAM, precipitate completely back out of the sludge, the residual wastewater additive concentration of 10% dilute - H2SO4, using a pH meter automatic control the dosage of add, through mixing machine mixing reaction, control of pH 7-9, gravity flow into the reservoir.  
    Reservoir, the water is mainly used to buffer, to meet the follow-up for adsorption filtration system, the liquid level control system of automatic control. Tested qualified water back into the sewage pipe network in the industrial park.
sludge pond sludge using sludge pump to filter plate and frame filter press, the filtrate flow back to adjust the pool again processing, filter cake to qualified unit for processing.
within this process equipment operation is basically automatic state, pH meter with NaOH and chain - H2SO4 dosing pump, can be controlled by pH meter automatic dosing amount of acid and alkali, guarantee the pH meets the demand of reaction. After the rest of the reagent dosage according to water quantity calculation need to manually control the dosing dosing pump. Filtering adsorption system controlled by the liquid level control system automatically.  
filter backwash adsorption systems: sand filter and carbon filter manually, backwash cycle according to the condition of water production. General backwash cycle for 24 to 36 hours at a time. Reverse osmosis membrane backwash cycle time setting for automatic control, general backwash cycle for 20 to 30 minutes at a time, back flush time for 1 to 2 minutes.
