UNITANK工艺应对高浓度废水冲击操作的可行性研究

高浓度难降解有机废水对已经适应了城市污水处理的生化处理系统造成了巨大的冲击,严重影响了生化系统的处理效果,以及正常的生产操作,同时生化系统受冲击后的恢复显得异常缓慢、延续的时间也较长.针对生产的操作,论述了应对措施和生产操作的调整,保持稳定的污泥浓度和活性,避免系统中生物毒素的积累;日常规范运营管理,稳定微生物的生长环境和生物种群结构,积极应对,保证系统处理运营效果、COD减排量、以及系统的稳定运营.

Feasibility and Operation of High Concentration Waste Water Impact of UNITANK Process Biochemical System

Feed with high concentration and degration-resistant organic mater, produce enormous impact for the biochemical operation system which has acclimatized municipal sewage, have a strong impact on treatment effect of biochemical system, the work statement of biochemical flora, the effluent quality, the COD emission reductions and, the normal production operation, the biochemical system seems slowly to recover after impact and, to last a long time. With a view to the treatment process traits of waste water treatment plant, analyzed the effects that resulting from high concentration and degration-resistant organic waste wa-ter impact, and based on the theory of waste water treatment and, the test of leachate and municipal sewage synergy treatment and, the impact test of different COD charge, and the key technology of high concentration and degration-resistant waste water treatment. Analyzed the feasibility operation, and put forward reference projects. In the process of daily operation management in waste water treatment plant, with a view to solutions to adjust and operate production, ensure stable operation statement and stable sludge concentration and activity, avoid the accumulate of biotoxin in biological system. Standard operation management, ensure biological system operate in suitable work conditions, avoid resulting from feed water quality and improper operation cause the change of environment of microbes growing and the structure of biotic population, resulting from abnormal problems happen. Thus at the accident statements, positively respond to ensure the treatment and operation effect, and COD emission reduction quantity, and stable operation system.
