The invention provides a brownification copper waste liquid treatment process based on secondary ultraviolet light catlaysis. The process includes the steps of: S1) regulating the pH value of the brownification copper waste liquid, and performing primary filtration to the brownification copper waste liquid; S2) under ultraviolet light catlaysis condition, performing initial oxidization; S3) performing secondary oxidization under the ultraviolet light catlaysis condition; S4) regulating the pH value of the brownification copper waste liquid treated in the step S3), and performing secondary filtration to the brownification copper waste liquid; S5) performing third oxidization; S6) neutralizing the brownification copper waste liquid treated in the step S5), and performing third filtration tothe neutralized brownification copper waste liquid; S7) performing flocculating settlement to the brownification copper waste liquid treated in the step S6), and discharging supernatant. The method can achieve harmless treatment to the brownification copper waste liquid, reduces environmental pollution and has excellent environment benefit. In addition, the method is low in cost and saves cost, and has great economic benefit.
Description
technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to a process for treating brown copper waste liquid based on secondary ultraviolet light catalysis. Background technique [0002] Brown copper waste liquid is a kind of industrial wastewater, which contains a lot of organic matter, and direct discharge will cause environmental pollution. Therefore, it is necessary to treat the brown copper waste liquid before discharge. Due to the high concentration and complex composition of organic matter in the brown copper waste liquid, potassium permanganate oxidation method can be used to oxidize the organic matter. However, potassium permanganate oxidation method potassium permanganate is expensive, and the cost is relatively high, so it is not suitable for the actual demand of industrial production. Therefore, in view of the above problems, it is necessary to propose a further solution. Contents of the invention ...
