Description

Technical Field

[0001] The utility model relates to a deodorization technology for sludge drying carrier gas, and more specifically, to a biological deodorization system for deodorizing drying carrier gas. Background Art

[0002] Sludge treatment has always been an important step in the sewage treatment process. Excessive sludge accumulation not only has a significant impact on the environment, but also brings great problems to the energy efficiency conversion of the entire sewage treatment process. The sludge drying system usually includes several drying devices, which are used to convert wet sludge into dry sludge. During the drying process of the sludge drying device, due to the layout of the existing sludge drying system and the microorganisms cultivated by the biological section in the deodorization box, it is very easy to produce problems such as excessive carrier gas concentration, high treatment requirements, excessive biological section, biological section filler blockage, and large fluctuations in the drying deodorization carrier gas volume and concentration, which urgently need to be improved.

[0022] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Combination Figures 1 to 3 As shown, the utility model provides a biological deodorization system for deodorizing a dry carrier gas, comprising a circulating water pool 1, an accelerator storage tank 2, a water storage tank 3 and a control box 4.

[0024] The water pump 11 in the circulating water pool 1 is connected to a continuous spraying device 5 , and the continuous spraying device 5 extends to the top of the biological section 61 in the composite deodorizing box 6 .

[0025] The accelerator storage tank 2 is connected to the circulating water pool 1 through a DN15 hose 7.

[0026] The circulating water pool 1 and the water storage tank 3 are both connected to an external water source via a DN50 water supply pipe 8 .

[0027] The control box 4 is used to control the water pumps in the circulating water pool 1 and the water storage tank 3 .

[0028] The water storage tank 3 is communicated with the water washing circulation pump 10 .

[0029] The size of the circulating water pool 1 is 2000 mm×1500 mm×1500 mm.

[0030] The diameter of the water storage tank 3 is 1880 mm.

[0031] The composite deodorizing box 6 is connected with a drain pipe 9 .

[0032] The utility model biological deodorization system converts the original water washing section into a circulating water pool 1 and a water storage tank 3 area, and plays a cooling role in the biological section 61 through the temperature water washing volume, ensuring that the temperature of the biological section 61 is between 30 and 35 degrees. At the same time, a continuous spraying device 5 is added to the biological section 61, and large-particle plastic balls of DN70 are used as fillers of the biological section 61 to alleviate various blockage problems caused by high odor concentration in the biological section 61. Finally, an accelerant storage tank 2 is added to stabilize the odor concentration at the outlet of the biological section 61.

[0033] The washing system formed by the circulating water pool 1 and the water storage tank 3 can basically maintain a stable daily water exchange volume according to the temperature of the sewage during operation, and can increase the treatment capacity of a part of the washing odor while reducing the temperature.

[0034] The continuous spraying device 5 is located at the inlet of the biological section 61 of the composite deodorizing box 6 and is equipped with an odor temperature detector, which is interlocked with the water washing circulation pump 10 to further ensure that the temperature of the biological section 61 is between 30 and 35 degrees.

[0035] The self-produced activated sludge is put into the biological stage 61 to cultivate targeted microorganisms and improve the treatment effect of the biological stage 61. At the same time, the promoter storage tank 2 is added to predictively add promoters before the odor concentration at the inlet of the biological stage 61 increases or the odor volume increases, so as to improve the microbial treatment capacity and resist the treatment requirements of the increase in odor concentration, so that the outlet of the biological stage 61 is less affected by the fluctuation of the process parameters of the inlet stage, and stabilize the odor concentration at the outlet of the deodorization equipment.

[0036] The utility model biological deodorization system can effectively improve the capacity of the biological stage 61, so that the hydrogen sulfide removal rate reaches 99%, and the outlet TVOC can be effectively removed by 50%.
