Problems solved by technology

At present, the commonly used fillers in China are fixed fillers such as honeycomb fillers, soft fillers, semi-soft fillers and composite fillers. However, these fillers often encounter problems such as blockage, agglomeration, and uneven air and water distribution during use, which affects The biological treatment effect is improved. And the above-mentioned fillers need to be installed on the auxiliary support, which causes many inconveniences such as filler installation and replacement, and relatively increases the project investment and operation management costs.

Embodiment 1

[0014] Polyethylene 50kg, polypropylene 35kg, carbon black 6kg, iron oxalate 7kg, magnesium oxalate 4kg, antioxidant 2kg. The non-woven suspension filler of the present invention can be prepared according to the conventional method in the industry.

[0015] The density of the non-woven suspension filler is 0.95g / cm 3 .

[0016] Further, the non-woven suspended filler can be reinforced and formed by a hot fusion method in a circular, regular polygonal sheet shape or a cylindrical shape.

Embodiment 2

[0018] Polyethylene 40kg, polypropylene 25kg, carbon black 10kg, iron oxalate 3kg, magnesium oxalate 6kg, antioxidant 1kg. The non-woven suspension filler of the present invention can be prepared according to the conventional method in the industry.

[0019] The density of the non-woven suspension filler is 1.05g / cm 3 .

[0020] Further, the non-woven suspended filler can be reinforced and formed by a hot fusion method in a circular, regular polygonal sheet shape or a cylindrical shape.

[0021] In the present invention, by adding inorganic compounds to the production materials, the characteristics of the materials are changed, the adhesion ability of microorganisms is improved, and the fillers are easily regenerated or replaced in actual use every week, the air and water distribution are uniform, the production is simple, and the cost is low. The transportation is convenient, so when the present invention is used for sewage treatment, the water treatment effect is improved....

Abstract

The invention discloses a non-woven cloth suspension filler which is prepared by the following constituents in parts by weight with the conventional method: 40-50 parts of polyethylene, 25-35 parts of polypropylene, 6-10 parts of carbon black, 3-7 parts of ferric oxalate, 4-6 parts of magnesium oxalate and 1-2 parts of antioxidant. The specific gravity of the non-woven cloth suspension filler is closed to that of water. No fixing support is required. The filler can suspend in the water in a pool with aeration stirring and is uniformly fluidized in the whole pool. The energy consumption is low, and the non-woven cloth suspension filler has a good prospect.

Description

technical field [0001] The invention relates to a suspension filler, in particular to a non-woven suspension filler. Background technique [0002] Packing is one of the key technologies in biofilm wastewater treatment. In the biofilm method, the filler, as a place for microorganisms to inhabit, is one of the key technologies of wastewater treatment, and its performance directly affects the treatment effect and investment cost. [0003] At present, most of the biochemical methods are used to treat urban sewage and industrial organic wastewater, including activated sludge method and biofilm method. Due to the low sludge concentration of the activated sludge method and the small treatment load, the civil construction investment is high and the floor area is large; while the biofilm method currently mostly uses suspended fillers, which increases the investment of the support, and has a small specific surface area; some The plastic ball suspension filler is used, the diameter is...
