Abstract

The invention provides a fluidity biocarrier containing high pore diatom. The fluidity biocarrier consists of the high pore diatom and adjuvant, wherein the adjuvant is poly aluminium chloride or polymerization aluminium chloride, and the mass ratio of the high pore diatom to the adjuvant is (65-75):(25-35). The fluidity biocarrier is added into sewage treatment to take the effects of adsorption and flocculation, in addition, the fluidity biocarrier is combined with microorganisms in a biological pool to form the fluidity activity sludge biocarrier, biochemical treatment efficiency is greatlyimproved, various industrial sewages and domestic sewages can be processed, in addition, the fluidity biocarrier has the advantages of good treatment effect, low cost, small land occupation, and sewage is processed fundamentally. The fluidity biocarrier can be used for manufacturing porous carrier particles and is applied to river control and the like.

Description

Technical field: [0001] The invention belongs to the field of environmental protection, and relates to a fluid biological carrier, in particular to a fluid biological carrier containing high-porous diatoms. Background technique: [0002] The carriers currently used in my country can be roughly divided into three categories: the first category is stereotyped fixed carriers, mainly honeycomb carriers; the second category is suspended carriers such as soft carriers, semi-soft carriers, elastic three-dimensional carriers, combined Type carriers, etc.; the third type are stacked and suspended carriers, such as Pall rings, stepped rings, hollow spheres, suspended particles, etc. But the field of liquidity carrier is still blank. Invention content: [0003] In view of the above-mentioned technical problems in the prior art, the present invention provides a fluid biological carrier containing highly porous diatoms, and the fluid biological carrier containing highly porous diatoms ...
