Abstract

The invention provides a honeycomb network pipe bio-carrier suitable for a biological contact oxidation pond for solving problems of low film-forming speed and small film-forming quantity of the traditional bio-carrier and low transfer efficiency of a bio-carrier area. The honeycomb network pipe bio-carrier consists of a honeycomb network pipe bio-filler which is prepared from modified polyethylene, modified polyvinyl chloride or modified polypropylene material; carbon black and polyvinyl alcohol components are added into the carrier; and the honeycomb network pipe bio-filler is a honeycomb filler formed under the thermal physical adhesive effect of a plurality of network pipes, the single network pipe is hollow, the diameter of the network pipe is 8 to 12 centimeters, the single network pipe is cut into small network pipes with the lengths of 60 to 80 centimeters, and the upper parts and the bottom parts of a plurality of small network pipes of 60 to 80 centimeters are adhered together through thermoplastic to form the honeycomb network pipe bio-filler. The addition of the carbon black and polyvinyl alcohol components improves the hydrophilic property of the bio-carrier and the adhesive ability of microbe, and remarkably improves the film-forming speed and film-forming quantity.

Description

(1) Technical field [0001] The invention relates to water treatment technology, in particular to a cellular network management biological carrier. (2) Background technology [0002] As an efficient water treatment process, the biofilm method has achieved widespread success in organic wastewater treatment projects, and its key technology is the application of biological fillers suitable for microbial attachment and growth. The application of different types of biological fillers leads to different types of biofilm reactors, including traditional biological filters, biological rotary aerated biological filters, biological fluidized beds, and biological contact oxidation tanks. Among the many biofilm reaction processes, the biological contact oxidation process is a biological treatment technology between activated sludge and biological filter. It is a biofilm method with the characteristics of activated sludge method, and has the advantages of both. It is highly valued by wate...
