Embodiment 1

[0050] Embodiment 1, biological treatment device and treatment method of chlorine-containing organic volatile pollutants

[0051] Pollutants to be treated: chlorobenzene volatile organic compounds, the intake chlorobenzene concentration is between 200-1000ppm, the normal value is about 500-600ppm, the intake air volatile organic compound concentration is between 400-2000ppm, the normal value is about 1000ppm, the flow rate 20000m 3 / h.

[0052] Depend on figure 1 As shown, the biological treatment device of the chlorinated organic volatile pollutants of the present embodiment includes an air intake pipeline 1, a biological treatment box and an exhaust pipeline 2. The upper part is arranged in turn: biological filter bed 3, biological filter bed spray system 4, growth-promoting bacteria group silo 5, hopper spray system 6; Functional flora and growth-promoting flora on the bed filler; the biological filter bed spray system 4 is arranged above the biological filter bed for sp...

Embodiment 2

[0087] Embodiment 2, biological treatment device and treatment method of chlorine-containing organic volatile pollutants

[0088] Pollutants to be treated: the same as in Example 1.

[0089] The biological treatment device and treatment method of the chlorinated organic volatile pollutants of the present embodiment, except the following parameters, all the other are identical with embodiment 1:

Abstract

The invention discloses a biological treatment device for chlorine-containing organic volatile pollutants and an application thereof. The biological treatment device for the chlorine-containing organic volatile pollutants includes a gas intake pipeline 1, a biological treatment box and an exhaust pipeline 2. According to the direction of inflow of the chlorine-containing organic volatile pollutants, the biological treatment box is provided with a biological filter bed 3, a biological filter bed spraying system 4, a growth-promoting flora bin 5, and a bin spraying system 6 from bottom to top insequence. Growth-promoting floras flow into the biological filter bed 3 at the lower side along with water and are used for supplementing growth-promoting floras to the biological filter bed 3. The growth-promoting floras are continuously supplemented to the biological filter bed, so as to treat the chlorine-containing organic pollutants with a biological method. The treatment device can realizepollution-free, low-cost and high-efficiency treatment of the chlorine-containing organic pollutants; the final chlorine-containing product is inorganic chloride salt and has quite low ecological impact, and the energy consumption of the device in use is quite low; the treatment device can treat the chlorine-containing organic pollutants with the highest concentration of up to 656 ppm.

Description

technical field [0001] The invention relates to the field of exhaust gas purification, in particular to a biological treatment device and application of chlorine-containing organic volatile pollutants. Background technique [0002] Chlorine-containing organic pollutants have always been a difficult point in the treatment of chemical pollutants, such as high-residue pesticides, which are difficult to degrade in the natural environment for 20 years, and the residues in water and soil are very considerable. Surveillance creates threats. [0003] The existing chlorine-containing organic pollutants are mainly treated by incineration and alkali neutralization. However, the incomplete incineration and the large amount of waste generated after treatment are still harmful to the environment; at the same time, the incineration method consumes a large amount of Alkali, although the equipment investment in the early stage is low, the cost of subsequent treatment of waste and consumed a...
