More Information
Summary:The invention discloses an acid phase method chlorinated polyethylene production wastewater treatment process method and system. The acid phase method chlorinated polyethylene production wastewater treatment process method comprises the following steps: (1) neutralizing: adding NaOH into a neutralizing tank to neutralize acid wastewater to be neutral; (2) cross-flow filtration: removing suspended matters in the neutralized wastewater by adopting a cross-flow filter; and (3) membrane separation: treating the cross-flow filtered wastewater by adopting disc-tube type reverse osmosis equipment, enabling the wastewater to enter equipment of the disc-tube type reverse osmosis equipment, removing residual organic matters in the wastewater and soluble salt generated after neutralization reaction, discharging formed clear liquid from a purified water outlet of the disc-tube type reverse osmosis equipment, discharging a concentrated solution containing organic matters and salt from a concentrated solution outlet; and (
