Embodiment Construction

[0021] The preparation and application of the novel biofilm carrier of the present invention are described in conjunction with the accompanying drawings.

[0022] Polyurethane sponge filler belongs to organic polymer filler. Its porous and transparent structure greatly increases the specific surface area of ​​the product, which is conducive to the proliferation of microorganisms. It is currently a commonly used biofilm carrier in MBBR reactors; zeolite is a porous silicate with a large specific surface area. It is easy for microorganisms to attach to the hanging film. The zeolite powder obtained by grinding zeolite not only has the properties of zeolite, but also can remove 95% of ammonia nitrogen in water and purify water quality. Therefore, in order to avoid the introduction of other chemical substances, the preparation of the novel biofilm carrier of the present invention selects zeolite powder and polyurethane sponge to be combined through physical rotation to form a novel...

Abstract

The invention discloses preparation and application of a novel biofilm carrier, the novel biofilm carrier comprises two carrier monomers, namely polyurethane sponge and zeolite powder, respectively, and the two kinds of carriers of the polyurethane sponge and the zeolite powder are combined into the novel biofilm carrier under physical rotation. The e density of the carrier can be increased, so that the density of the carrier and the density of water are closer, the disadvantage that the traditional polyurethane sponge is easy to float in the water is avoided, the adsorption and degradation ofpollutants by microorganism are facilitated, the biomass is increased by 0.997 + / -0.192 g / L, and the denitrification efficiency is increased by 5.1 + / -1.8%. The operation is simple in, and the novel biofilm carrier does not introduce chemical substances, has a low investment cost at one time, and is easy to be applied in practice.

Description

technical field [0001] The invention belongs to the field of biological treatment of waste water or sewage, and in particular relates to the preparation and application of a novel biofilm carrier. Background technique [0002] With the development of petrochemical, food and pharmaceutical industries, and the continuous improvement of people's living standards, the content of nitrogen and phosphorus compounds in urban sewage and landfill leachate has risen sharply, resulting in eutrophication in some water bodies in my country. Therefore, denitrification Phosphorus has gradually become one of the research focuses of environmental workers. The MBBR process is a sewage treatment process that combines the biofilm method of attached growth and the activated sludge method of suspended growth. The high efficiency and operational flexibility of the mud method are regarded as "the most promising sewage treatment technology in the future". [0003] In the application of MBBR, the sel...
