Abstract

The invention relates to the technical field of water body purifiers and in particular relates to a water body purifier based on kieselguhr. The water body purifier based on kieselguhr is prepared from the following substances in parts by weight: 80-150 parts of kieselguhr, 20-40 parts of starch, 5-6 parts of glutaraldehyde, 30-60 parts of polyhydroxy-alcohol, 5-10 parts of acrylamide, 1-3 parts of an initiator, 0.1-0.5 part of organic silicate ester, 10-30 parts of organic titanate, 2-6 parts of a silane coupling agent and 50-60 parts of a solvent. As the kieselguhr, the grafted amphoteric starch and the modified titanium dioxide are compounded, the water body purifier has integral functions of adsorption, flocculation, catalytic degradation and the like, and a function of purifying waterbodies in all directions is achieved. In addition, the water body purifier provided by the invention is wide in raw material source, low in cost, wide in application range and wide in application prospect.

Description

technical field [0001] The invention relates to the technical field of water body purifiers, in particular to a diatomite-based water body purifier. Background technique [0002] Protecting precious water resources is an important issue, especially for my country, where the per capita fresh water resources only account for a quarter of the world's average level. Although many laws and regulations on the protection of water resources such as sewage discharge have been promulgated one after another, our country started relatively late in this regard. According to relevant research, more than 50% of groundwater resources in my country have been polluted, and the proportion of inferior fifth-class water is also low. up to 30%. Therefore, it is imperative to purify polluted water sources and adopt efficient sewage treatment materials and technologies. [0003] Traditional water purification agents mainly use chlorine gas and hypochlorous acid. Although the effect of sterilizatio...
