摘要: 松香深加工废水中有机污染物成分复杂、浓度高、浓度变化大、分子质量大、难降解、废水排放量波动大等特点。用传统的物化处理、生化处理等处理工艺,废水较难保持稳定达标排放。本研究在传统的物化加生化处理工艺上进行改进和完善,有效解决了松香深加工废水处理难的问题。首先利用浓缩处理办法处理松香深加工过程中产生的高浓度有机废水,再利用物化加生化相结合的综合处理方法处理COD浓度相对较低的混合废水,使处理后废水保持稳定,达到国家一级排放标准(GB 8978-1996),并可作为厂区绿化用水、冷却水系统补充水、水循环真空泵用水等循环使用。

Abstract: Organic pollutants in rosin processing wastewater have the characteristics complex of composition, high concentration, high molecular weight, being hard to be degraded, great changes on the concentration. Discharge of wastewater hiyhly fluctuates. It is hard to keep the wastewater discharge up to the standard stably using the traditional physical-chemical treatment and bio-chemical treatments. The treatment method in this paper is to make improvement on the traditional physical-chemical-biochemical treatment method, and efficiently solve the difficulties of rosin processing wastewater treatment. Firstly, the inspissation treatment is used to deal with the high concentration organic wastewater yielded from the rosin deep-processing production. Secondly, physical-chemical-biochemical synthetic treatment method was used to deal with the mixed wastewater with low COD concentration. Then the wastewater discharge can reach primary discharge standard specified in GB 8978-1996, and can be recycled for landscaping, water cooling system, and water ring vacuum pump, etc.

Key words: concentration treatment, physical-chemical treatment, bio-chemical treatment, discharge up to standard, recycle use
