一种基于生物多糖的污水处理剂及其在污水处理工艺中的应用

A New Type of Biological Polysaccharide Based Wastewater Treatment Regent and Its Application in Wastewater Treatment Techniques

摘要: 随着我国经济和社会的快速发展，对资源的需求急剧增长。大量资源的使用给环境造成了严重的负担，每年产生大量的污水，这些污水的排放给人类的生存也带来了巨大的威胁，因此，污水处理是现代科学发展面临的最严峻的问题之一。本技术建立了一种新型基于生物多糖的污水处理剂及其制备方法，涉及污水处理技术领域，其中基于生物多糖的污水处理剂由纤维素交联壳聚糖，活性炭，硅藻土，聚合氯化铝，十二烷基硫酸钠和水组成；本发明以纤维素交联壳聚糖作为改性剂，对传统活性炭、硅藻土污水处理剂进行改性，纤维素经氧化后含有大量的羧基，羧基可以与壳聚糖中的氨基交联反应，形成复杂的交联网状结构，该结构与活性炭、硅藻土混合后，活性炭、硅藻土的微孔结构得到了很好的保护，大分子颗粒物不会进入其表面的微孔，导致吸附效果下降。

Abstract: With the rapid development of China’s economy and society, the demand for resources has increased rapidly. The use of a large number of resources has caused a serious burden on the environment, producing a large number of sewage every year, and the discharge of such sewage has also brought a huge threat to human survival, wastewater treatment is one of the most serious problems in the development of modern science. The invention relates to a novel wastewater treatment agent based on biological polysaccharide and a preparation method thereof, which relates to the technical field of wastewater treatment, wherein the wastewater treatment agent based on biological polysaccharide is crosslinked by cellulose, Chitosan, active carbon, diatomite, the invention uses cellulose cross-linked Chitosan as modifier to modify the traditional activated carbon and diatomite sewage treatment agent, and the cellulose contains a large number of carboxyl groups after oxidation, carboxyl groups can react with Amino groups in Chitosan to form a complex cross-linked network structure. When the structure is mixed with activated carbon and diatomite, the micro-pore structure of activated carbon and diatomite is well protected, macromolecular particles will not enter the surface of the micro-pores, resulting in reduced adsorption.
