Problems solved by technology

[0003] Polyamide has good hydrophilicity and bio-affinity, but its weak impact strength greatly limits its application as a filler in water treatment biochemical pools. If the strength problem of this fiber can be solved, its application In the field of water treatment, it can greatly improve the sewage treatment performance of biochemical pools

Embodiment 1

[0029] The specific steps of a method for arranging a composite fiber biological filler for sewage treatment are:

[0030] 1) Production of modular packing:

[0031] The first step: the production of the frame, welding the stainless steel 304 square tube with a specification of Ф15×15×1.5 into a 2000×1200mm stainless steel frame 1, welding diagonal braces in the frame to make the structure stable, and the material of the diagonal braces Same as framework ( figure 1 );

[0032] The second step: the production of polyamide net, prepare 12 long 1200mm, the polyester cloth strip 3 of wide 20mm, the polyamide fiber 4 (120D / 36F) of long 2000mm is turned on the polyester cloth strip 3 with sewing machine ( figure 2 , image 3 );

[0033] The third part; the making of polyester mesh, the same size and manufacturing method as polyamide fiber mesh 5 ( figure 2 , image 3 );

[0034] The fourth step: the production of filling ( figure 2 , Figure 4 ), put the polyamide fiber ...

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...
