针对各股废水水质特点,先采用气浮工艺和铁碳微电解-fenton氧化工艺分别预处理甲苯和真空泵废水,预处理后的两股废水再与其他废水混合进行生物处理. 运行结果表明:在高甲苯废水、真空泵废水及其他废水进水水质分别为COD:3 500, 3 210 mg·L-1和424 mg·L-1;SS:250,280 mg·L-1和278 mg·L-1;NH3-N:0,0,2.72 mg·L-1;TP:0,0,0.34 mg·L-1;甲苯:288,0 mg·L-1和0.53 mg·L-1;乙酸:2 600,13.6 mg·L-1和32.5 mg·L-1的条件下,综合废水最终出水COD、SS、NH3-N、TP、甲苯、和乙酸分别为209,236,1,0.14,0.07 mg·L-1和2 mg·L-1,出水的各项指标均低于化工园区内集中污水处理厂的接管标准,此工程的实施可为化工园区的污水治理提供借鉴.

The wastewater treatment project of the solvent chemical plant is designed on a scale of 15 200 m3·a-1. As a kind of refractory chemical wastewater, the wastewater from the solvent chemical plant has a high level of Methylbenzene and acetic acid. According to the wastewater quality, the methylbenzene and the vacuum pumps wastewater were first treated by flotation and micro-electrolysis/Fenton oxidation respectively, then they were retreated by biological process when mixed with other wastewater. Results of the treatment project showed that the COD, SS, NH3-N, TP, methylbenzene, acetic acid of the final effluent were 209, 236, 1, 0.14, 0.07, 2 mg·L-1 respectively when the influent COD was 3 500, 3 210 mg·L-1 and 424 mg·L-1 respectively, the influent SS was 250, 280 mg·L -1 and 278 mg·L -1 respectively, the influent NH3-N was 0, 0 mg·L -1 and 2.72 mg·L -1, respectively, the influent TP was 0, 0, and 0.34 mg·L-1 respectively, the influent methylbenzene was 288, 0 and 0.53 mg·L-1 respectively, and the influent acetic acid was 2 600, 13.6 mg·L-1 and 32.5 mg·L-1 respectively for the methylbenzene, vacuum pumps and other wastewater. The effluent indexes were lower than the influent standard of the sewage treatment plants in the chemical industry park. The implementation of the project can provide reference for the wastewater treatment of chemical industrial parks.
