Problems solved by technology

[0003] In recent years, the use of FRP has been increasing, and the waste FRP has also increased accordingly. Because it is difficult to degrade and has the disadvantages of polluting the environment, it has attracted great attention. The common method of disposing of waste FRP is incineration or landfill, but Incineration will produce waste gas, pollute the atmosphere, landfill itself will occupy land resources, and solid waste is difficult to degrade, polluting the soil

Embodiment

[0010] A biofilter deodorizing filler, comprising a bottom layer, a middle layer and a top layer arranged from bottom to top, wherein the bottom layer is made of volcanic rocks with a diameter of 5-8cm, and the middle layer is made of stone rice with a weight ratio of 5%-10%, 30 -40% ceramsite, 15%-20% FRP block coated with nano particle layer, 20%-30% peat soil and 10%-15% volcanic rock with a diameter of 2-3cm, the top layer It is formed by stacking FRP blocks coated with a layer of nanoparticles on the surface. The size of the FRP block is 5×5 cm.

[0011] The volcanic rock at the bottom layer has more pores and has high mechanical strength, which can be used as a supporting structure and facilitates the intake and adsorption of odor. The stone rice in the mixed filler in the middle layer is alkaline, which can preserve the acid and alkali inside the filler layer. Balance degree, ceramsite has a relatively large area and strong rigidity, which can absorb odor and act as a ...

experiment example 1

[0014] Experimental Example 1: A biofilter deodorizing filler, using the technical solution of the embodiment of the present invention, with a filler height of 150 cm. Among them, the bottom layer is 20cm thick, and it is piled up with volcanic rocks with a diameter of 5-8cm; the middle layer is 100cm thick, and the mixed filler used is composed of 5% stone rice, 40% ceramsite, and 15% with a size of 5×5cm and surface coating. FRP with nano particle layer, 30% peat soil, 10% volcanic rock with a diameter of 2-3cm are mixed; the top layer is 30cm thick, which is FRP with a size of 5×5cm and coated with nano particle layer on the surface.

experiment example 2

[0015] Experimental example 2: A kind of deodorizing filler for a biological filter, the filler is divided into three layers, and the total height is 150cm. Among them, the bottom layer is 20cm thick, which is piled up with volcanic rocks with a diameter of 5-8cm; the middle layer is 100cm thick, and the mixed filler used is composed of stone rice with a weight ratio of 5%, ceramsite with a weight ratio of 40%, and 15% with a size of 5×5cm and no nanometers on the surface. The granular layer of FRP, 30% peat soil, and 10% volcanic rock with a diameter of 2-3cm are mixed; the top layer is 30cm thick and is FRP without nanoparticle layer on the surface.

Abstract

The invention discloses a deodorizing filler for a biofilter. The deodorizing filler comprises a bottom layer, an intermediate layer and a top layer which are arranged from bottom to top, wherein thebottom layer is formed by accumulating volcanic rocks having the diameter of 5-8cm; the intermediate layer is formed by mixing the following materials in percentage by weight: 5-10 percent of stone grains, 30-40 percent of ceramsites, 15-20 percent of glass reinforced plastic blocks having the surface coated with a nano-particle layer, 20-30 percent of peat soil and 10-15 percent of volcanic rockshaving the diameter of 2-3cm; and the top layer is formed by accumulating glass reinforced plastic blocks having the surface coated with a nano-particle layer. The deodorizing filler has the advantages that the three-layer structure mode has strong adsorbability and large specific surface area, favors microbe growth and reproduction and odor adsorption, has high structural strength and long service life and can achieve the aim of waste utilization.

Description

technical field [0001] The invention relates to the technical field of biological deodorization, in particular to a deodorizing filler for a biological filter. Background technique [0002] Odor treatment methods include physical deodorization, chemical deodorization and biological deodorization, among which biological deodorization has the advantages of good treatment effect, low energy consumption and no secondary pollution, and has been widely used. The filler is the core component of the biological deodorization method, which can provide an environment for the growth and metabolism of microorganisms, and its structural components have a greater impact on the deodorization effect. [0003] In recent years, the use of FRP has been increasing, and the waste FRP has also increased accordingly. Because it is difficult to degrade and has the disadvantages of polluting the environment, it has attracted great attention. The common method of disposing of waste FRP is incineration...
