| 摘 要： | 中密度纤维板生产废水的特点是高CODcr、高SS,针对这种废水的水质特点,确定采用混凝法进行预处理。混凝剂选用PAC、PAFC、PFS、FeCl_3,助凝剂选用PAM,通过试验,首先筛选出PAFC和PFS两种无机混凝剂单独投加时处理效果较好,CODcr去除率可达到55%左右,再将这两种混凝剂分别与PAM联合投加后,最终确定以1.0g/L的PFS和10mg/L的PAM联合处理时效果最好,CODcr去除率可达到75%,每t水预处理价格为1.8元。

| Abstract: | According to the characteristic of sewage from MDF plant-high CODcr and high SS,the coagulation process was chosen as pre-treatment method,and PAC,PAFC,PFS,FeCl3 were selected respectively as coagulant and PAM as the coagulant additive.The result showed the treatment effect of PAFC or PFS was better than that of other coagulants when adding inorganic coagulant only,and the removal rate was about 55%.Combined with PAM,PAFC or PFS had improved effect.The best treatment effect was obtained under the conditions of adding 1.0g/L of PFS combined with 10mg/L of PAM,and the removal rate could reach 75% with the cost of treatment being 1.8yuan per ton of wastewater. |
