Embodiment 1

[0039] Suspended filler for sewage treatment, the overall shape is spherical, with a modified coating on the surface, the diameter is 10-60mm, and it is integrally injection molded. The material of the suspended filler is lightweight anti-corrosion material, in this embodiment, it is high-density polyethylene. Suspended packing includes packing sheet 1 and packing core 2. Filling sheet 1 is a semi-annular thin sheet with a diameter of 10-60 mm and a thickness of 0.5-1.5 mm. Filling core 2 is a hollow sphere, the surface layer is sealed with high-density polyethylene, and the interior is hollow. The thickness of the surface layer is 0.5-1.5 mm, and the packing sheet 1 is arranged symmetrically and radially in the three-dimensional space around the packing core 2. The packing sheet 1 and the packing core 2 are arranged concentrically and the inner diameter of the packing sheet 1 is equal to the outer diameter of the packing core 2. The surface of the filler is treated with modif...

Abstract

A providd suspended filling material used for sewage processing is characterized in that the filling material is integrally in the shape of a ball, the surface is provided with a modified coating, and the diameter is 10-60 mm; the filling material comprises filling-material sheets and a filling-material nucleus; each filling-material sheet is a semi-annular thin sheet, and the filling-material nucleus is a hollow ball; the filling-material sheets are arranged in the tri-dimensional space round the filling-material nucleus in a radial manner; and the filling-material sheets and the filling-material nucleus are arranged in a concentric way, and the internal diameter of each filling-material sheet is equal to the external diameter of the filling-material nucleus. The suspended filling material is easy for film formation, and because the filling-material nucleus is hollow, the filling material is easy to suspend after a film is formed.

Description

technical field [0001] The invention belongs to the field of sewage treatment and relates to suspended fillers, in particular to suspended fillers for sewage treatment. Background technique [0002] In recent years, with the continuous improvement of the discharge standards of sewage treatment plants, a certain proportion of biological suspension fillers have been put into the aeration tanks of many sewage treatment plants in the process of standard upgrading and transformation, forming a sludge-film symbiotic sewage treatment process. The process increases the biomass and biological species in the aeration tank by adding a certain amount of suspended carrier to the aeration tank, thereby improving the treatment efficiency of the aeration tank. Suspended fillers are mainly made of polyethylene and polypropylene, and auxiliary components are added appropriately, and the density is generally controlled at 1.0g / cm 3 about. Therefore, when aerated, it is completely mixed with ...
