Embodiment 1

[0023] This embodiment provides a synergistic VOC biological treatment method, the specific operation steps are as follows:

[0024] 1) The VOC exhaust gas is treated once through polyurethane filler or PP inorganic filler, and the centrifugal fan or blower can be used to pump the VOC exhaust gas into the polyurethane filler or PP inorganic filler through positive or negative pressure. Keep spraying the polyurethane filler or the inorganic filler of PP with circulating water, so that the microorganisms in the circulating water can form a film on the surface of the polyurethane filler or the inorganic filler of PP, and inject the nutrient solution into the circulating water while spraying the circulating water , to discharge the generated waste liquid in a concentrated manner. The polyurethane filler or PP inorganic filler has light and porous characteristics and is a good carrier for microbial growth. At the same time, the circulating water can ensure the ideal humidity of the ...

Embodiment 2

[0029] Such as figure 1 As shown, a cooperative VOC biological treatment system includes a cooperative biological treatment system, a circulating spray device and an intermittent irrigation device. The filter unit is connected with the circulating spraying device, and the biological filtering unit is connected with the intermittent irrigation device; the circulating spraying device is also connected with a nutrient solution injection device. The nutrient solution injecting device may inject the nutrient solution into the pipeline of the circulating spraying device through a pump, or inject the nutrient solution into the interior in other ways.

[0030] Specifically, the biological trickling filter unit is a biological trickling filter tower, and the biological trickling filter tower is provided with polyurethane filler or PP inorganic filler; the bottom of the biological trickling filter tower below the polyurethane filler or PP inorganic filler is provided with an anti-corros...

Abstract

The invention belongs to the technical field of domestic waste gas treatment, and discloses a method and system of cooperative VOC biological treatment. The method of cooperative VOC biological treatment comprises the following specific operation steps: (1) performing first treatment on VOC exhaust gas, spraying circulating water in the process of the first treatment, and injecting a nutrient solution into the circulating water while the circulating water is sprayed; and (2) performing secondary treatment on the treated VOC exhaust gas, and performing intermittent water spraying during the secondary treatment. The system of collaborative VOC biological treatment comprises a cooperative biological treatment system, a circulating spraying device and an intermittent irrigation device, and thecooperative biological treatment system comprises a biological drip filter unit and a biological filter unit which communicate with each other; and the biological drip filter unit is connected with the circulating spraying device, the biological filter unit is connected with the intermittent irrigation device, and the circulating spraying device is also connected with a nutrient solution injection device. Through the method and system of cooperative VOC biological treatment, saving of land occupation, reduction of investment, no secondary pollution and saving of a lot of operation cost achieved.

Description

technical field [0001] The invention belongs to the technical field of domestic waste gas treatment, and in particular relates to a cooperative VOC biological treatment method and a cooperative VOC biological treatment system. Background technique [0002] With the rapid development of global industry, the problem of environmental pollution has become more serious, and strict regulation of pollution control is required. Moreover, the diversification of types of pollution sources and the continuous generation of new pollutants have triggered various approaches to more effectively address pollution problems. [0003] Volatile organic compounds have various impacts and harms on human health. Long-term exposure to volatile organic compounds or being in an environment with a large content of volatile organic compounds will greatly damage human body functions. The current chemical and printing industries will produce a large amount of volatile VOC organic waste gas, which will po...
