Abstract

The invention discloses a composite fiber modular bio-filler and its layout method used for sewage treatment in the new material field for environmental protection. It fixes the polyamide fiber and polyester fiber webs on the stainless steel frame, where the polyamide fiber web is placed in the middle and the polyester fiber web is on both sides to form a modular composite fiber structure of three-tier network. It first installs the channel beam or angle steel mold base in the biochemical treatment pool, which connects the biochemical pool through the expansion bolts; the filler connects the channel beam through its stainless steel framework and is arranged according to the adjacent column crossing method and at an angle of 55 DEG-75 DEG between the module and the biochemical pool bottom.The invention can greatly reduce the cost of supporting structure and has a strong capacity to resist shock load. It can improve the number of microorganisms per unit volume in the biochemical pool, improve the wastewater treatment performance, the original pool pollutant volume load and the capacity to resist water impulse and also has the features as easy installation and maintenance.

Description

technical field

[0001] The invention relates to a composite fiber modular biological filler for sewage treatment and an arrangement method thereof, belonging to the field of new environmental protection materials. Background technique

[0002] Biofilm method is one of the important methods of sewage biological treatment. Filler is the carrier of biofilm attachment, and is the core of biofilm technology such as biological contact oxidation method and biofilter, which directly determines the treatment effect and investment benefit of the process. At present, the common biological fillers on the market are mainly made of high molecular polymers such as polypropylene, polyethylene, polyvinyl chloride or polyester, and generally include soft fillers, semi-soft fillers, elastic fillers, composite fillers, etc. These materials have the advantages of high strength, long material life, and good acid and alkali resistance, but they also have the disadvantages of slow film formation an...
