Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

Referring to fig. 1 to 3, the following technical solutions are adopted in the present embodiment: a whole-process biological deodorization device of a sewage treatment plant comprises a water inlet end 1, a pretreatment device 2, a biological pool 3, a secondary sedimentation pool 4, a water outlet 5 and a sludge dewatering workshop 6, wherein the whole-process biological deodorization device comprises a culture pool 7 and a deodorization microbial reactor 8, the water inlet end 1 is connected to the biological pool 3 through the pretreatment device 2, the biological pool 3 is sequentially connected with the secondary sedimentation pool 4 and the water outlet 5, the secondary sedimentation pool 4 is also respectively connected to the sludge dewatering workshop 6, the culture pool 7 and the water inlet end 1, the deodorization microbial reactor 8 is arranged in the culture pool 7, the deodorization microbial reactor 8 comprises an equipment shell 81, a filler A82, a filler B83, a pore plate 84 and a steam stripping device 85, wherein the filler A82, the filler B83 and the steam stripping device 85 are sequentially arranged in the equipment shell 81 from top to bottom, and the pore plate 84 for water inlet and outlet is arranged at the bottom and the top of the equipment shell 81.

It is noted that the orifice plate 84 is a stainless steel plate with an aperture of 3 mm.

In addition, the stripping device 85 is a circular HDPE stripping device, and the circular HDPE stripping device is connected with a stainless steel pipe.

The working principle of the specific embodiment is as follows: the biological deodorization of overall process is with newly-built culture pond of sewage treatment plant, installs deodorization microbial reactor device in the culture pond. Sewage in a sewage treatment plant enters water from the bottom of the deodorization microbial reactor device, and is discharged from the top of the deodorization microbial reactor device through a steam stripping device in the deodorization microbial reactor device. A filler A, which is a main component of the deodorizing microbial reactor, is used as a filler consisting of a filler B, which plays the role of a microbial habitat, and is used for culturing soil microbes with strong activity for removing malodorous smell and humifying excess sludge. The malodorous substances N compound, S compound and other compounds are removed from the source, so that the malodorous substances are not dispersed, and the putrefactive staphylococcus can be reduced. As the number of aerobic bacteria increases, the number of nitrite bacteria, nitrate bacteria, and denitrifying bacteria increases, and nitrogen components (ammonia, etc.) in the wastewater are removed. And (3) refluxing the sludge with the soil microbial flora in the secondary sedimentation tank to a water inlet end (the reflux ratio is 2-5% of the water inlet amount) through a sludge submersible pump, so that the deodorization of the whole sewage treatment plant is realized, namely the whole process deodorization.

The filler A in the specific embodiment is synthesized, has a diameter of 4 mm and is brown. The filler A is embedded with the deodorizing microorganism strains to play a role in inoculation, and is added with a proper amount of auxiliary agents to achieve a slow release effect through a pressing process. Different from the conventional packing technology, the deodorant microorganism bacteria are embedded, and meanwhile, the deodorant microorganism bacteria can catalyze and stimulate the growth and enrichment of deodorant microorganism flora, stimulate the life activities of microorganisms and increase the activity of enzymes required in biological reaction.

The filler B and the filler B are natural materials, the diameter is 30-50mm, and the filler B is white. The filler B is a filler rich in silicate and trace elements, and the dissolved effective components of the filler B can promote the reaction of microorganisms and metabolites thereof with the oxa-o substances and can play a role of a microorganism carrier.

The steam stripping device is circular, and adopts the HDPE material, and the pipeline material adopts 304 stainless steel or higher grade stainless steel. Mainly plays 2 roles: 1. the stripping action leads the sewage in the sewage treatment plant to pass through a stripping device in the deodorization microbial reactor device, and the sewage is discharged from the top of the deodorization microbial reactor device. 2. Oxygen is diffused and supplemented, and dissolved oxygen required by the formation of the next generation of microorganisms is met.

The deodorizing microbial reactor of the present embodiment is a place where soil microbes are proliferated and cultured, and a round filler a and a filler b are filled in the deodorizing microbial reactor. The aerobic and anaerobic mixed soil microorganisms in the deodorizing microorganism reactor are stably passed through, normal metabolic activity is started, and then the removing effect on malodorous substances and nutrient salt substances is generated. The deodorizing microbial reactor has the function of providing the activity time and space for maintaining soil microbes, and the retention time is preferably 24-48 hours.
