The invention discloses a preparation method of printing and dyeing wastewater treatment agent, which belongs to the field of sewage treatment. The invention uses sodium hydride to deprotonation of the shell, the slag will remove the stratum corneum, during the milling and the addition of surfactant and full contact, reduce the surface tension of shell powder, and the coupling agent was modified, a significant increase in the specific surface area, the existence of unsaturated surface valence bond the large number of oxygen-containing groups, which has strong adsorption ability of dye, on the other hand can be deposited in the wastewater of dye molecules cross-linked, thereby reducing the COD and chroma of wastewater, and the microbial activity can change the heavy metals, heavy metals into non-toxic compounds, both play a coordinating role in dealing with the good effect of printing and dyeing wastewater, will not have two pollution on the environment. The invention solves the problem that the components in the current treatment agent make the treated water contain trace toxic substances, which may cause the two pollution of the water body for a long time.

一种印染废水处理剂的制备方法
本专利技术属于污水治理领域,具体涉及一种印染废水处理剂的制备方法。
技术介绍
印染废水是加工棉、麻、化学纤维及其混纺产品为主的印染厂排出的废水。印染废水水量较大,每印染加工1吨纺织品耗水100~200吨,其中80~90%成为废水。纺织印染废水具有水量大、有机污染物含量高、碱性大、水质变化大等特点。在工业各行业中,纺织印染业的COD排放量位居第四位,全国纺织印染废水每天排放量为3×106~4×106m3,占工业废水总排放量的35%,属难处理的工业废水之一。可见印染行业的污水排放急需治理,印染厂排放的污水中主要包括漂炼废水、印花、染色废水和退浆水,染料虽不像农药那样具有很强的急性毒害作用,但人们已经在偶氮染料、蒽醌染料、三苯甲烷染料中发现具致突变性和致癌作用的品种,染料的降解产物也多为联苯胺等一些致癌的芳香类化合物。染料作为一类结构稳定的有机化合物,具有抗酸、抗碱、抗光、抗微生物等特性,在环境中有较长的滞留期,水体中极低浓度的染料,也会影响受纳水体的正常功能,对水生微生物和鱼类也有毒害作用使整个水生生态系统的多样性下降。因此染料对环境的负 ...
