Problems solved by technology

These two technologies make full use of the wear-resistant and durable performance of rubber powder and the adsorption performance of activated carbon for organic matter and bacteria. The treatment efficiency is high, but the cost is also high.
[0006] The formulations of the above fillers do not specifically adjust the specific gravity of the product, and the application is limited in some occasions

Embodiment 1

[0023] Raw materials: 1000g of 40-mesh rubber powder, 200g of 40-mesh quartz sand as a specific gravity regulator, 400g of EVA resin as a binder, 100g of corn flour, 2000g of water, 10g of alum, and 10g of activated sludge dry powder.

[0024] Manufacturing method: Heat rubber powder, quartz sand, and EVA while stirring until the EVA melts, and the evenly mixed EVA is wrapped on the surface of rubber powder and quartz sand to obtain a mixture with a porous structure. Cut the mixture into desired shapes. It can be processed into strips using a plastic extruder, then hot cut or cooled and then cut to the desired size. Some special shaped products require a specific forming process. Cool the cut and shaped material to below 100°C to set the shape.

[0025] Add about 100g of water to alum, and heat to prepare a solution above 90°C.

[0026] Heat the corn flour with an appropriate amount of water to make a thick porridge at about 90°C. Add the cut and shaped materials, mix well...

Embodiment 2

[0029] Raw materials: 1000g of 40-mesh rubber powder is selected, no specific gravity regulator is added, 300g of epoxy resin + curing agent is used as the adhesive, and 100g of corn flour is used as the active filler.

[0030] Manufacturing method: Mix rubber powder, corn flour, epoxy resin + curing agent together, and mix well to obtain a mixture with a porous structure. When the resin gradually solidifies and reaches a certain viscosity, the mixture is extruded and cut into the desired shape. Put the cutting product into a large amount of corn flour and completely solidify it to obtain an active microbial carrier without inoculated microorganisms, which is suitable for long-term storage.

[0031] The above-mentioned active microbial carrier can be added with water and inoculated with microorganisms 20-40 days before use to obtain a pre-inoculated active microbial carrier.

Embodiment 3

[0033] Raw materials: 1000g of 40-mesh rubber powder is selected, no specific gravity regulator is added, 300g of self-vulcanized rubber glue is used as a binder, and 100g of feed powder is used as an active filler.

[0034] Manufacturing method: Mix rubber powder, feed powder, and self-vulcanized rubber glue together, and mix well to obtain a mixture with a porous structure. When the glue dries gradually and the mixture reaches a certain strength, the mixture is extruded and cut into the desired shape. The cutting product is put into a large amount of feed powder and completely solidified to obtain an active microbial carrier without inoculated microorganisms.

Abstract

An active microbe carrier in the form of particle, short tube, plate or block, band, etc for the biologic treatment of sewage contains rubber powder, specific weight regulator, adhesive and active filler chosen from dried microbe powder and dried active mud powder.

Description

technical field [0001] The invention relates to the biological treatment technology of various organic polluted water, especially the active microorganism carrier used in the submerged biofilm treatment technology. Background technique [0002] Biofilm plays an important role in the biological treatment of organically polluted water. The early biofilm carriers used natural materials such as slag, bamboo chips, and wood strips, and then developed honeycomb or corrugated packing materials made of paper, glass fiber reinforced plastic, plastic, etc., and ring-shaped packing materials made of plastic, ceramics, etc. Multi-faceted, hollow spherical, spherical and other stacked packings, suspended soft semi-soft packings made of polymer materials such as plastics, elastic three-dimensional packings, etc. Suspended packings made of lightweight plastics were developed around 1990. The material of the above-mentioned filler is inert, has a small specific surface area, does not promo...
