Problems solved by technology

However, it is very difficult to fluidize these materials. Not only does it consume a lot of energy, but once fluidized, it will also be lost due to mutual collision and friction into powder.

Embodiment Construction

[0011] The present invention will be further described according to the above-mentioned accompanying drawings. The invention is composed of a composite wing plate 1, a fixed ring 2, an intermediate fixed ring 3, a water-repellent foam plastic 4 and a granular zeolite (molecular sieve) 5. The composite wing plate 1 is composed of granular molecular sieve material 5 arranged between two plastic plates 7, and the two plastic plates 7 are fixedly connected by fixing strips 6 arranged on the sides, so that the granular zeolite material 5 is firmly clamped between the plastic plates 7 without making them move. The middle part of the inner side of the composite wing plate 1 is fixedly connected with the middle fixed ring 3, and the upper and lower parts of the outer side are firmly fixedly connected with the fixed ring 2 to form a whole. In the middle fixed ring 3, a water-repellent foam plastic 4 is set according to the sewage condition. The specific gravity of the suspended filler...

Abstract

The novel functional suspension filler is used in processing various organic sewage. The functional water processing material grains or blocks are sandwiched in plastic plates to form composite winged plate and are used as the main carrier for microbe to attach and propagate on them to form biomembrane with flourishing growing microbes. The functional suspension filler contains water repellent foamed plastic to regulate water specific weight, so that the functional suspension filler may be fluidized together with water and gas and the mass transferring of microbe, organic matter in waste water and oxygen in the air is reinforced. The functional water processing material can adsorb and enrich pollutant in waste water to raise the elimination of pollutant effectively, and the microbe can regenerate the functional material biologically. The present invention has high organic sewage processing effect.

Description

technical field [0001] The invention relates to a functional suspension filler for water treatment and its production technology, which is used for the treatment of various organic sewage. Background technique [0002] In the purification of various organic sewage by biological contact oxidation, a variety of suspended fillers have been developed. These suspended fillers are basically made of plastics such as polyethylene, polystyrene, and polypropylene as raw materials for microorganisms. Due to the hydrophobicity of these plastics, microorganisms are not easy to attach to their surfaces, and these plastic fillers have no other functions except as carriers for the attachment of microorganisms. [0003] On the other hand, some materials with special water treatment functions, such as: zeolite (molecular sieve) can adsorb ammonium ions, activated carbon can adsorb organic matter, due to their physical properties, these materials can only be made int...
