连续辊压中密度纤维板废水处理系统工艺设计

摘要

Coagulation-anaerobic oxidation-bio-contact oxidation combinated process was used to treat the wastewater char-acteristics Heilongjiang Xinglong medium density fiberboard Co.,Ltd. of annual output 50,000 m3 of continuous roll medium density fiberboard production line. The result shows that,the wastewater treatment system runs steadily with good efficiency. Effluent quality index can reach Ⅱ-class criteria specified in Integrated Wastewater Discharge Standard(GB 8978-2002), purified water can not only be recycled in the factory,and the activated sludge produced by-products can also be sold as a business. This process has a good environment and economy benefits.%针对黑龙江兴隆中密度纤维板有限公司年产5万m3连续辊压中密度纤维板生产线废水的水质特点，采用混凝-厌氧-好氧相结合的废水处理工艺。运行结果表明，该废水处理系统运行稳定，最终出水指标达到了GB 8978-2002《污水综合排放标准》中的二级标准，净化后的水不仅能在厂内循环利用，而且产生的活性污泥还可以作为企业副产品销售，具有良好的环境效益和经济效益。
