It will be appreciated that malodorous gases may enter the bio-filter chamber 13 through the air inlet 11. The spraying device 20 can spray clear water to the biological filter layer 14, so as to improve the wettability of the biological filter layer 14. In the biofiltration chamber 13, when the malodorous gas passes through the wet, porous and active microorganism-filled biofiltration layer 14, the malodorous gas is absorbed and decomposed into simple inorganic substances such as CO2, H2O, H2SO4, HNO3 and the like by utilizing the adsorption, absorption and degradation functions of microorganism cells on malodorous substances and the characteristics of small cell size, large surface area, strong adsorption and various metabolic types of microorganisms.

In this embodiment, the deodorization and purification apparatus may further include a blower 30. The fan 30 is used to drive the gas to flow in the direction from the gas inlet 11 to the gas outlet 12 in the apparatus body 10.

It can be understood that fixed connection, fixed mounting's mode can be welded fastening, screw fixation, joint fixed etc, the embodiment of the utility model provides a do not limit to this.

In one embodiment, as shown in fig. 2, the side of the apparatus body 10 is provided with a water circulation outlet 15 near the bottom. The deodorization purification apparatus may further include a water circulation precipitation device 40.

In one embodiment, the water circulation deposition device 40 may include: a tank 41, a flow guide 43 and a first overflow.

One side of the box 41 is provided with a water inlet 411, and the other side is provided with a water outlet 412. The water inlet 411 is located at a higher level than the water outlet 412.

The drainage piece 43 is fixedly installed on the bottom wall 413, two ends of the drainage piece 43 are fixedly connected with the inner walls of the box body 41 at two ends, and the height of the water inlet 411 is higher than that of the highest point of the drainage piece 43.

The drainage member 43 and the first overflow member 42 are arranged in this order in the water flow direction, a guide surface 431 is provided on the side of the drainage member 43 facing the first overflow member 42, and the height of the side of the drainage member 43 provided with the guide surface 431 is gradually reduced in the direction approaching the first overflow member 42.

A slow flow space is formed between the flow guide member 43 and the first overflow member 42, and a first deposition groove 415 is formed in the bottom wall 413 at the slow flow space. That is, the guide member 43 is positioned between the water inlet 411 and the first precipitation tank 415 for guiding the flow of water from the water inlet 411 to the slow flow space.

In this embodiment, the water at the bottom of the apparatus body 10 can flow out of the water circulation outlet 15 and enter the tank 41 through the pipe and the water inlet 411. When the water flows, a part of the impurities at the bottom of the apparatus body 10 may flow into the tank 41 together with the water. The water flow and the foreign substances flowing along with the water flow may flow onto the guide surface 431 by gravity and be caught in the slow flow space by the guide of the guide surface 431 and the blockage of the first overflow member 42. When the water in the tank 41 stays in the slow flow space, impurities in the water may fall down by gravity and be deposited in the first deposition tank 415. As the water entering the tank 41 increases, the liquid level of the water between the first overflow member 42 and the drainage member 43 rises, and when the liquid level rises to be higher than the highest point of the first overflow member 42, the water in the tank 41 can flow to the side of the first overflow member 42 close to the water outlet 412.

In this embodiment, when the first plug body 441 is inserted into the first opening 416, the first opening 416 is closed, and the water flow in the first deposition groove 415 cannot leave the first opening 416. When the first plug body 441 is removed from the first opening 416, the water flow in the first precipitation tank 415 may flow out from the first opening 416.

It can be understood that when the dirt deposited as the sludge in the first settling tank 415 needs to be cleaned, the worker can remove the first plug body 441 from the first opening 416 when the deodorization and purification apparatus stops working, so that the water between the drainage member 43 and the first overflow member 42 can flow out of the first opening 416 through the first settling tank 415, and at the same time, the dirt in the first settling tank 415 is driven to flow out of the first opening 416. The worker may flush the first deposition tank 415 through the first opening 416 after the first plug body 441 is removed from the first opening 416, to clean the first deposition tank 415.

The water near the water outlet 412 can flow to the spraying device 20 under the driving of the water pump 50 and is used for realizing the spraying to the biofiltration chamber 13.
