摘要
针对气化污水硬度高易结垢的水质特点,采用高密度沉淀池作为提标改造工艺,对其进行预处理。结果表明,硬度去除率达到72%,浊度去除率达到77%,一定程度缓解了装置结垢问题。但处理效果波动较大,主要原因是受来水分散剂影响。
In view of high hardness and easy fouling of the gasification sewage,the high density sedimentationtank was used for pretreatment as the transformation process. The results showed that the removal rate of the hardness could reach 72%,and the turbidity removal rate could reach 77%,it remits the device fouling problems ata certain extent. But the treatment effect fluctuate too much,which mainly effected water-reducing dispersant.
