Butadiene styrene latex wastewater treatment recycling system and treatment process thereof

Abstract

The invention discloses a butadiene styrene latex wastewater treatment recycling system and a treatment process thereof. The system comprises a preheating unit, an evaporation unit and a concentratedsolution recovery unit connected with one another, wherein a butadiene styrene latex wastewater stock solution is connected with an input end of the preheating unit by virtue of a stock solution delivery pipe; an output end of the preheating unit is connected with an input end of the evaporation unit by virtue of a preheated solution delivery pipe; an output end of the evaporation unit is connected with the input end of the concentrated solution recovery unit by virtue of a concentrated solution delivery pipe; condensate water discharged by the evaporation unit is discharged by a condensate water delivery pipe; a preheating unit and a condensate water pretreatment unit are connected in series onto the condensate water delivery pipe. The treatment process comprises the steps: performing evaporation and concentration treatment on the solution by an evaporation technology, evaporating and condensing water, and collecting the condensate water into a condensate water tank. The analytical result of the concentrated solution shows that the condensate water can completely meet the reclaimed water reuse standard, and the concentrated solution produced after evaporation can be used as a rawmaterial of a production device.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment and recycling of raw materials in wastewater, in particular to a styrene-butadiene latex wastewater treatment and recycling system and its treatment process. Background technique [0002] Industrial wastewater contains toxic substances that inhibit the growth of aerobic microorganisms. It is a biologically refractory organic wastewater. With the rapid development of science and technology and the continuous improvement of people's living standards, the problem of environmental pollution is getting worse, and water resources are also facing serious pollution. Problems, a large amount of industrial wastewater is not up to standard and discharged, most domestic sewage is discharged directly without treatment, and agricultural chemicals such as fertilizers and pesticides are used unreasonably in rural areas, which has an increasingly serious impact on surface water. Freshwater r...
