[0030] The present invention is further described below by way of examples.
[0031] Taking the waste water reuse treatment of a refrigerator compressor manufacturer in Jiaxing as an example, the process flow is as follows figure 1 shown. Wastewater generated during the manufacturing process of refrigerator compressors is collected through two collection pools: tank liquid, emulsion collection pool and cleaning waste water pool, and is collected in two categories: the emulsion and phosphorus used for machine tool cutting with small water volume, high concentration and complex composition are collected respectively. The bath wastewater produced in chemical, degreasing and anti-rust processing workshops, referred to as emulsification and bath wastewater, is collected in the bath and emulsion collection pools; the other is produced by steel pickling, surface cleaning, and cleaning after phosphating and degreasing. Wastewater with large water volume, low concentration and simple ...
