Abstract

The invention discloses a preparation method of an efficient dephosphorizing porous particle adsorbent. The method comprises the following steps of: (1) preparing raw materials: preparing dolomite clay and montmorillonite clay serving as raw materials; (2) granulating and casting: adding water, soluble starch and Al2(SO4)3 into the dolomite clay and montmorillonite clay serving as raw materials, fully and uniformly stirring, granulating, casting and drying; and (3) sintering. In the method, a production process is simple, production cost is low, and harm gases and sewage are not produced in a production process. The prepared adsorbent has high affinity to water body phosphorus, has high adsorption efficient, does not poison water bodies or aquatic organisms, and can be removed from water bodies conveniently after use. The prepared adsorbent has high adaptability on the aspect of phosphorus removal from phosphorus-containing water bodies, and can be applied to removal of phosphorus from industrial waste water, domestic sewage, agricultural runoff and other natural water bodies.

Description

technical field [0001] The invention relates to a preparation method of an adsorbent for sewage treatment, in particular to a preparation method of a highly efficient phosphorus removal porous particle adsorbent. Background technique [0002] The per capita possession of water resources in my country is small, and the spatial distribution is unbalanced. With the acceleration of urbanization and industrialization in my country, the demand gap for water resources is also increasing. At the same time, with the increase of urban population and the development of industrial and agricultural production, the amount of sewage discharge is also increasing, and the water pollution is quite serious, almost all over the country. In this context, the sewage treatment industry has become a new industry. [0003] Due to the high construction costs and operating costs of sewage treatment, many areas do not have a complete industrial wastewater and municipal domestic sewage treatment system...
