Embodiment Construction

[0015] according to figure 1 As shown, the present invention has foamed cement, activated fly ash is the carrier base material, and the functional auxiliary material is infiltrated into the carrier base material to become a porous carrier filler 1. The porous carrier filler is preferably a spherical hollow body with a specific gravity less than 1 , the ratio of the composition of the above materials is as follows, foamed cement: activated fly ash: functional auxiliary materials ≈ (15-50): (20-60): (5-30), and then on the outer surface of the porous carrier filler Stick a layer of porous active and magnetic powder material layer to become active suspension filler.

[0016] The present invention can also according to specific production steps, according to figure 1 , figure 2 Shown in more detail listed in the following four steps to complete:

[0017] The first step of making porous carrier filler:

[0018] 1. Prepare foamed cement samples first: foam the cement foami...

Abstract

The invention relates to an active composite suspended filler, which is applied to the technology of biochemical treatment of organic wastewater, and discloses a porous support filler formed by a carrier basic materials and functional assistant materials. The porous support filler is in a through-hole spheroidal body or a through-hole cylindrical body, and one layer of porous active powder material layer is bonded on an outer surface of the through-hole spheroidal body or the through-hole cylindrical body. The active composite suspended filler is an inorganic suspended filler, has an uneven surface and roughness height; and pores with different sizes are distributed on the filler and are shaped like a honeycomb. The filler not only has high adsorption performance on harmful substances and dissolved oxygen, but also can form different dissolving intensity, is beneficial to improving processing efficiency for removing COD (Chemical Oxygen Demand) and ammonia nitrogen, and will be a novel high-efficient filler.

Description

technical field [0001] The invention relates to a suspension filler used for biochemical treatment of organic wastewater, in particular to biochemical treatment of organic wastewater by utilizing an inorganic suspension filler. Background technique [0002] Biochemical treatment of organic wastewater is currently the most common, advanced and practical technology. The filler is the main carrier of biological bacteria and the place where they grow, reproduce and inhabit. Therefore, the properties, surface state, and surface area of ​​the filler will directly affect the effect of sewage treatment. [0003] Water treatment packing is usually divided into fixed packing and suspended packing. Suspended fillers are accepted by the market due to the characteristics of fillers in a moving state, high utilization rate of oxygen, and good treatment effect on pollutants such as COD and ammonia nitrogen, thereby saving investment. At the same time, it has many advantages such as low ...
