Problems solved by technology

The first method has the following disadvantages: 1. The filler is too dispersed in the system, which is inconvenient for maintenance and management during operation; 2. The filler flows irregularly under the influence of water flow, and the fillers collide with each other, which is not conducive to the film formation of the filler; 3. 、Part of the filler is easy to get stuck in the aeration system and water outlet system (such as decanter), which will affect the stable operation of the system

Abstract

The invention discloses a polyhedron hollow ball filler device, which comprises polyhedron hollow ball fillers, and also includes an outer frame and filler rods fixedly arranged inside the outer frame. According to the polyhedron hollow ball filler device provided by the invention, the polyhedron hollow ball fillers are fixed on the filler rods inside the outer frame, during system operation, water flow has no influence on the polyhedron hollow ball fillers on the filler rods, and the relative positions of the polyhedron hollow ball fillers do not change, thus reducing mutual friction of the polyhedron hollow ball fillers and providing a good environment for formation of a biofilm from the fillers. The invention also discloses a filler-cyclic activated sludge system and an installation method of the polyhedron hollow ball filler device.

Description

technical field [0001] The invention belongs to the technical field of water treatment. Specifically, the invention relates to a multifaceted hollow ball packing device, a packing-circulating activated sludge system with the same and an installation method of the multifaceted hollow ball packing device. Background technique [0002] At present, sewage (waste) water discharge standards are becoming more and more stringent, and the concentration and composition of pollutants in sewage are becoming higher and more complicated. Many sewage plants (stations) in my country will face the problem of standard upgrading and transformation. Adding biological carrier filler to the aerobic tank to increase the biomass in the system is an effective method in many aerobic unit upgrading measures. Multi-faceted hollow ball packing has the advantages of many blades, light weight, high strength, large free space, corrosion resistance, good surface hydrophilicity, and large specific surface ar...
