Application of rice husk-derived natural coagulant in drinking water treatment

doi:10.19965/j.cnki.iwt.2022-0962

Abstract

Abstract:

A rice husk-derived natural coagulant was prepared，and its structure and element composition were characterized. The purification efficiency of rice husk-derived coagulant was investigated through coagulation experiment，and the removal of organics with different hydrophobicity and molecular weight was further explored. The results showed that the rice husk-derived coagulant prepared could effectively remove macromolecular and hydrophobic organics，and the removal of small molecular and hydrophilic organics could also reach up to 40%. Compared with polyaluminum chloride，rice husk-derived coagulant could effectively control the formation of disinfection by-products in subsequent disinfection，and had certain advantages in the removal of trace antibiotics.

Key words: drinking water treatment, natural coagulant, separation of organic components, disinfection by-products, antibiotics

摘要：

以谷壳为原材料制备了一种天然混凝剂，并对其结构与元素组成进行了表征。通过混凝实验考察了谷壳混凝剂的净水效果，并进一步探究了不同亲疏水性、不同分子质量有机物的去除情况。结果表明，制备的谷壳混凝剂能够有效去除大分子、疏水性有机物，对小分子、亲水性有机物的去除率也可达40%。与聚合氯化铝相比，谷壳混凝剂可更有效地控制后续消毒中消毒副产物的生成，在痕量抗生素的去除能力方面也具有一定优势。
