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 explained based on the above drawings. The present invention is composed of a composite wing plate 1, a fixed ring 2, an intermediate fixed ring 3, a water-repellent foam 4 and a granular zeolite (molecular sieve) 5. The composite wing plate 1 is composed of a granular molecular sieve material 5 arranged between two plastic plates 7. The two plastic plates 7 are fixedly connected by a fixing strip 6 arranged on the side, and the granular zeolite material 5 is firmly clamped between the plastic plates 7 Do not move them in time. The middle part of the inner side of the composite wing 1 is fixedly connected with the middle fixing ring 3, and the upper and lower parts of the outer side are firmly connected with the fixing ring 2 to become one body. The middle fixing ring 3 is provided with water-repellent foam 4 according to the sewage condition The specific gravity of the suspended filler of the present invention is adjusted to ensure ful...

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 suspended filler for water treatment and its production technology, which is used for the treatment of various organic sewage. Background technique [0002] In the biological contact oxidation method to purify various organic sewage, a variety of suspended fillers have been developed. These suspended fillers are basically made of polyethylene, polystyrene, polypropylene and other plastics as raw materials and serve as carriers for microorganisms. Due to the hydrophobicity of these plastics, microorganisms are not easy to adhere to their surfaces, and these plastic fillers have no other functions in addition to being a carrier 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, and activated carbon can adsorb organic matter. Due to the nature of their materials, these mate...
