Problems solved by technology

Natural processing materials have a wide range of sources, but poor film formation and unfavorable growth of microorganisms, so the effect on sewage purification is not obvious
Artificial synthetic materials are generally added with bioaccelerators, which are beneficial to the attachment and growth of microorganisms, but secondary pollution will occur in the production process, and because of their high price, they are difficult to produce on a large scale, so they are not easy to promote

Embodiment Construction

[0010] The present invention is an improvement on the biological filter bed technology, so the pretreatment of sewage, the design of the filter bed, the backwash of the filter tank and the design of subsequent structures belong to the known technology.

[0011] Specific implementation examples:

[0012] For a certain river sewage, the treatment technology of the present invention is adopted, and the treatment capacity is 1000m 3 / d, the treatment process is "sewage → grille → lifting → natural ecological treatment system → discharge", and the recommended process is "sewage → coarse and fine grille → lifting → natural ecological treatment system (or filter) → discharge, which can Effectively reduce various pollutants in the sewage, and the effluent reaches the first-level B or first-level A standard of the "Comprehensive Wastewater Discharge Standard". At the same time, it can effectively reduce the entire project cost and operating cost.

Abstract

The technology of treating sewage with ecologically active filler belongs to the field of improved biofiltering technology. The present invention includes underground reinforced concrete structure, ecological greening, and natural active filler of shell and other solid waste capable of attaching microbes and stimulating the activity of microbes to eliminate organic matter from sewage. The biofilter with both aerobic region and anaerobic region has the functions nitrating, denitrifying and dephosphorizing to eliminate pollutant from sewage effectively, and is suitable for treating city sewage, river sewage and industrial effluent.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a natural ecological sewage biological treatment technology using oyster shells and pearl shells as active fillers. Background technique [0002] Biological filter bed technology is used for the purification treatment of urban sewage, river mixed sewage and industrial sewage. It is a common and effective sewage treatment technology. The key to biological filter bed technology is the choice of filler. The fillers currently used mainly include natural processed materials such as quartz sand, gravel, pebbles, anthracite, coke, activated carbon, and ceramsite, and artificial synthetic materials such as polyethylene and polypropylene plastics. Natural processing materials come from a wide range of sources, but they are poor in film formation and unfavorable for the growth of microorganisms, so the effect on sewage purification is not obvious. Synthetic materials are general...
