Description

Technical Field

[0001] This utility model relates to wastewater purification technology, specifically a biological sponge packing frame. Background Technology

[0002] The biological sponge packing material is mainly polyurethane sponge packing material. Polyurethane sponge is formed through a double explosion process involving oxygen and hydrogen, resulting in uniform and interconnected pores. This allows the entire biological sponge packing material to serve as a microbial carrier. Due to the special structure of this biological carrier, the breakthrough lies in achieving nitrification on the outer surface of a single biological carrier within the aeration tank, and denitrification of nitrite inside. This involves not only simple physical adsorption but also the attraction of positive and negative charges, giving the carrier surface certain cationic active groups and hydrophilic groups such as hydroxyl groups. These groups can form bonds and valences with negatively charged microorganisms in wastewater, thus firmly fixing the microorganisms and enzymes onto the carrier. This prevents the surviving microorganisms from being lost under the shearing action of water and air, resulting in a large microbial loading capacity and high volumetric loading. This allows for the simultaneous reduction of ammonia nitrogen and total nitrogen in wastewater. It also has advantages such as strong bubble-cutting ability, high space utilization, and no dead zones, making it an ideal product for microbial carriers in current biological treatment technologies.

[0003] Polyurethane foam is mainly in the form of cubes with dimensions of 30mm, 40mm, 50mm, and 60mm. Therefore, conventional polyurethane foam needs to be placed in plastic filler balls to prevent it from moving with the liquid flow. However, filler balls can only hold a small number of polyurethane foam blocks, resulting in limited purification capacity. Therefore, in the case of large water bodies or large volumes of sewage, a large number of filler balls need to be put in, which leads to high costs and makes it difficult to quickly replace the filler balls later.
