Abstract

This invention belongs to flocculating agent field. It is especially used to process flocculating agent of spray painting waste water and its application. Flocculating agent of spray painting waste water, of which characteristic is: it is made up of DZ-11 flocculating agent and DZ-12 polycoagulant. Wherein, DZ-11 has strong charge neutralization function. It can quickly neutralize oil paint particle electric charge, and remove glutinosity; DZ-12 polycoagulant has strong condensation, which can gather oil paint particle that lose glutinosity; proportion by weight of DZ-11 flocculating agent and DZ-12 polycoagulant is between 0.5-2:1. Spray painting waste water method, of which characteristic is: independently deposit above DZ-11 flocculating agent and DZ-12 polycoagulant, dissolve respectively, and utilize at then same time; adjust waste water PH to 8.5-10.5, add DZ-11 flocculating agent which is 5-8% of paint content of waste water at circulating water pump entrance; decrease glutinosity of circulating water that contains paint by using spray painting flocculating agent, add DZ-12 polycoagulant which is 6-10% of paint content of waste water at circulating water pump exit.

Description

technical field [0001] The invention belongs to the field of flocculants, in particular to a flocculant for treating spray paint wastewater and its application. Background technique [0002] The spray paint wastewater treatment agent is used to treat the waste paint produced in the wet spray paint wastewater of industries such as automobiles, mobile phones and furniture. The current spray paint wastewater treatment agent uses a single flocculant component, which has poor recovery effect of waste paint. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a new two-component spray paint wastewater treatment agent and its application. [0004] The spray paint wastewater treatment agent is characterized in that: it is composed of DZ-11 flocculant and DZ-12 flocculant, wherein, DZ-11 has strong charge neutrality, can quickly neutralize the charge of paint particles, and eliminate stickiness; DZ- ...
