Embodiment 1

[0018] refer to figure 1 , a filler for waste gas biological treatment, including a roughly triangular base ring 1, the three corners of the base ring are arc-shaped, and the sides are slightly concave inward, and the support frame 2 arranged in the cavity of the base ring , the support frame is composed of three fixed legs 3 arranged in a star shape, and the outer ends of the legs are connected to the base ring. The cavity of the base ring also includes a filling piece 4 for increasing the specific surface area. There are multiple filling pieces, which are evenly arranged vertically on the base ring. The outer ends of the filling pieces are connected with the base ring and extend out of the base ring. The base ring. A substantially triangular reinforcing ring is also provided in the cavity of the base ring, and the sides of the triangle are also slightly concave inward to form an arc, and the reinforcing ring is fixedly connected to the base ring. Both ends of the filling s...

Embodiment 2

[0020] Below in conjunction with the embodiment of application effect comparative test, the present invention will be further described. Parallel test: set up a group of 4 transparent plexiglass towers with a diameter of 150mm and a height of 600mm, the height of the filler installation is 350mm, and the 4 towers are operated in parallel. The towers are filled with chemical filler A made of polypropylene and chemical filler made of polypropylene. Filler B, biological filler C described in Example 1 of the present invention, and porous ceramic particles (cylindrical) D have the same process conditions such as air intake load and nutrient solution spraying amount. The specifications and application effects of the four fillers are shown in Table 1.

[0021] The results showed that:

[0022] The maximum air intake is 4×1m 3 / h, toluene concentration 500~800mg / m 3 Under the conditions, after 8 months of continuous operation (to ensure the stable growth of biofilm on the filler),...

Abstract

The invention relates to a filler for exhaust gas biological treatment. The filler comprises a quasi-triangular base ring and a support in the cavity of the base ring. The support comprises support legs, the support legs are fixedly connected, the outer ends of the support legs are connected to the base ring, a filler piece for increasing a specific surface area is arranged in the cavity of the base ring and the outer end of the filler piece is connected to the base ring. The exhaust gas biological filler has a large specific surface area in use, high amount of porosity and small filler bulk density, is not easily compacted and improves exhaust gas treatment efficiency.

Description

technical field [0001] The invention relates to a bulk packing used in a waste gas biological treatment device. In particular, it relates to a filler with changed geometric structure, which belongs to the field of waste gas purification. Background technique [0002] Biological filtration is a new technology with good effect and low investment and operating costs in the waste gas treatment process, and the filler is an important part of the biological filtration system. Packing properties have a great influence on the operating performance and stable operation of filtration equipment. Fillers for waste gas biological treatment, like chemical fillers, require good mass transfer performance and stable physical and chemical properties; on the other hand, they also have something in common with water treatment biological fillers, that is, they are required to attach and grow more microorganisms, But the difference is that they are not suspended in the water body for a long tim...
