Abstract

This is a pilot-test study.It treats the secondary water of wastewater treatment plant in Shanghai Petrochemical Co.by using combinative technics of coagulation and sedimentation, sandflow filtration, micro-electrolysis bactericide, then carrying out the reuse treatment.The treated water can be used as circulating cooling water.The test shows wastewater reuse device can easily work continuously and provides good efficiency.CODCr can be reduced from an average of 70.18 mg/L to 39.88 mg/L, turbidity can be reduced from an average of 30.83 NTU to 1.58 NTU,SS can be reduced from an average of 27.67 mg/L to 1.61mg/L and the total number of bacteria can be reduced to less than that in the standard of reuse water(100 mL-1).Furthermore, the device has good impact resistance.
