Problems solved by technology

However, the measures and methods taken by people to cultivate domesticated microorganisms are limited, so the number of dominant bacteria that domesticated microorganisms can benefit sewage treatment is limited, and the activity is not very strong, so the effect on water treatment is not very ideal.
In addition, no matter what kind of process there is a common problem - the problem of odor
Secondly, due to the unsatisfactory water treatment effect, a large amount of sludge will be produced. If this part of dewatered sludge is not handled properly, it will pollute the environment again

Abstract

The invention discloses a microbe composite carrier in the effluent disposal course, which comprises the following parts: 45-60 percent main material, 15-30 percent biological affinity material, 5-15 percent biological hydrophilic material, 18-28 percent adhesive, 2-8 percent foaming agent, wherein the main material is eroded soil, powder coal ash, calcium silicate, kaolin, brown hematite and or zeolite; the biological affinity material is starch and or calcium alginate; the hydrophilic material is diatomaceous soil; the adhesive is soluble silicate and or cement; the forming agent is hydrogen peroxide solution. The making method comprises the following steps: grinding materials at 100-200 order according to proportion; adding water and foaming agent to stir; graining; moulding; gluing at 40-70 deg.c; drying; solidifying; obtaining grain size phi at 20-30mm*60-70mm column state grain with 20-100 mum millipore diameter, 100-300m2 / g specific surface area and 1.18-1.21g / cm3 specific gravity.

Description

technical field [0001] The invention relates to a kind of sewage treatment that can improve the water treatment effect, remove the foul smell, nitrogen and phosphorus in the water, and the sludge after dehydration does not have secondary corrosion, and can be used as a high-efficiency organic fertilizer for soil improvement or topdressing Microorganism composite carrier. Background technique [0002] At present, most of the sewage treatment in our country is to domesticate and cultivate a large number of microorganisms in the sewage system, and use them to decompose organic matter, so as to achieve the purpose of purifying sewage. However, the measures and methods that people take to cultivate domesticated microorganisms are limited, so the number of dominant bacteria that domesticated microorganisms can benefit sewage treatment is limited, and the activity is not very strong, so the effect on water treatment is not very ideal. In addition, no matter what kind of process, t...
