Abstract:
The coagulation - CAF air flotation - V filter process has been applied to the treatment and reuse of wastewater from steel works. The number and size of the main constructs and the parameters, such as the number,specification, etc. of the main equipment are listed. The economic benefit analysis indicates that $19 209 600 is economized every year. The actual running result indicates that the effects of the removal rates of CODCr, SS and oil are obvious. The discharged water quality absolutely meet the requirements of the Second Grade of Shanghai Comprehensive Effluent Discharge Standard, and the requirements of reuse standard in enterprises.
