摘要
对煤制气厂原有污水处理系统的生产工艺和改进后污水处理系统的生产工艺进行比较 ,原设计工艺系统年投入资金为 2 1 .4 71万元 ,改进后年投入资金为 8.651万元 ,每年节约运行费用 1 2 .82万元 ,且改进后的生产工艺基本杜绝了工业废水外排对环境造成的污染 .
It has introduced the former sewage treatment systematic technique and the improved sewage treatment systematic technique of the Gas Plant.By the improved technique,it has basically stop the drainage of the industrial waste water which polluted the envivnoment.Thus,it can save about 128,500 yuan of the cost anually.
