Problems solved by technology

Recently, the patents whose publication numbers are CN1762851A, CN101066800A and CN102887591A disclose the use of high-density polyethylene material as the base material and the addition of modified functional materials to prepare biological carriers. Although the prepared biological carriers have roughness and large specific surface area , long service life and other advantages, but there are also disadvantages such as the long time required for the biological carrier to form a film, and the outer surface of the carrier is not easy to form a film.

Embodiment Construction

[0029] Implementation Example 1

[0030] Take 0.8 kg of talc powder with a fineness of 100 mesh or more and 7.2 kg of starch, mix them, add 72 kg of high-density polyethylene, mix them evenly, and send them into the extrusion barrel. The head temperature reached 130°C. The vegetative biological carrier for waste water treatment according to the present invention can be made.

[0031] The vegetative biological carrier used for wastewater treatment prepared in this example was compared with the biological carrier directly prepared from pure high-density polyethylene in terms of density, impact strength and tensile strength, and the comparison results are as follows:

[0032]

[0033] Implementation example 2

[0034] Take 0.8kg of talc powder with a fineness above 100 mesh, 2.4kg of starch, 2.4kg of ferric oxide, and 2.4kg of coke and mix them, then add 72kg of high-density polyethylene, mix them evenly, and send them into the extrusion barrel. The machine heats up, the te...

Abstract

The invention provides a nutritional type bio-carrier for wastewater treatment. The base material is high density polyethylene, the nutritional functional material is starch, ferric oxide, coke and slag powder, and the auxiliary material is talcum powder. The nutritional type bio-carrier for wastewater treatment provided by the invention has density of 0.93-1.05g / cm<3>, and has rough surface, large specific surface area and strong impact resistance, and can prevent the drop of a microbial film attached to the carrier outer surface in water due to friction between carriers. After film formation, the dehydrogenase activity and biomass on the carrier surface are more than twice those of the high density polyethylene directly made carrier. The bio-carrier contains the enhancement components of bio-enzyme, can promote the catalytic effect of bio-enzyme, has high bioactivity and fast metabolism, and can significantly enhance the decomposition ability of pollutants in water. Containing antiultraviolet components, the bio-carrier has a service life of over 30 years, and has no need for replacement and maintenance.

Description

technical field [0001] The invention relates to a biological carrier for wastewater treatment, in particular to a nutritional biological carrier for wastewater treatment. Background technique [0002] The biofilm moving bed method is widely used in the sewage treatment process because of its advantages of stable operation, high load impact resistance, economy and energy saving. The core technology of the biofilm moving bed method is the biofilm carrier, and the characteristics of the biofilm carrier determine the efficiency of the moving bed biofilm treatment process. However, most of the currently produced biofilm carriers are directly made of polymer resin materials such as polyethylene and polypropylene. The removal rate is low. [0003] High-density polyethylene has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. Recently, the patents whose publication numbers are CN1762851A, CN101066800A an...
