[0027] like figure 1 As shown, the latex processing wastewater of Hainan Sinochem Rubber No. 2 Plant was taken as the research object for advanced treatment:
[0028] (1) Lime milk coagulation treatment of latex processing wastewater: the latex processing wastewater of Hainan Sinochem Rubber No. 2 Plant enters the coagulation treatment unit, and a coagulant is added to the treatment unit. The coagulant is lime milk or lime milk and polyaluminum , stirring at 150r / min for 30-60s quickly, then stirring at 75r / min for 15-20min at a slow speed, free sedimentation for 30-50min, and taking CODcr, TP, and sediment amount as test indicators for the treated wastewater to screen the coagulant type and Consumption amount (referring to Table 1), wherein, the addition amount of milk of lime is to make the pH value of wastewater to be treated reach 7-8, and milk of lime is the emulsion that mass volume ratio is 10%. The water quality in the latex processing wastewater of Hainan Sinochem Ru...
