摘要
利用污泥焚烧残渣制备得到的Y189药剂是一种酸性药剂,成分复杂,主要以铁盐为主,并含有多种能对混凝起辅助作用或微生物生长所需的金属离子,以及含量较低的有害元素。分析了该药剂对印染综合废水的处理效果以及循环使用的可能性,指出循环使用后有害元素不会对生化处理造成抑制作用和导致生化出水中有害元素超标,但会出现生化出水CODCr会超标和总磷在Y189药剂中累积的问题。提出了Y189药剂改性的途径和总磷回收利用的设想。
The Y189 addictive made by sludge incineration residue is a kind of acid and complicated addictive. It is composed of ferric salt mainly and also consists of metallic ion which could be coagulation assistant and important to microorganism physiology and some low content harmful elements. This paper analyzed the effects and the recycling possibilities of this addictive on dyeing wastewater treatment and demonstrated that on inhibitory on bio-treatment will come from these harmful elements in recycling and the harmful elements content meet the standards, but the effluent CODcr content will exceed standards and total phosphorous will accumulate in Y189. Finally, this paper brought the way to improve Y189 and plan for phosphorous reclaim.
