Description

Deodorization unit generated from the Sewage and waste water

The present invention relates to a deodorizing device for removing odor generated in sewage and wastewater, and more particularly in sewage and wastewater that can remove sulfur-based odor components in an environmentally friendly manner while removing various odors generated in sewage and wastewater. It relates to a deodorizing device for removing odor generated.

Various household sewage and industrial wastewater generated in general households are discharged to the sewage treatment plant through sewage pipes buried in the ground and then discharged to the stream through separate purification treatment.

In this process, the wastewater flowing through sewage pipes is often decayed by the action of various bacteria during the flow. As it passes through the sewage pipes, biological oxygen demand (BOD), chemical oxygen demand (COD) and dissolved oxygen (DO) In addition to the higher values, various harmful gases such as ammonia, CO2, SO2, and methane are generated, and various pests inhabiting the pipeline spread water-borne diseases.

In particular, organic matters contained in large amounts in sewage and waste water are extremely unstable and easily decay, odors may occur when decaying, and may be changed into substances harmful to humans and ecosystems, and may cause hygiene problems.

Furthermore, in the summer, when the temperature is hot, the amount of gas generated increases, causing severe odor when the sewage pipe is opened, and hydrogen sulfide generated by organic decay inside the pipeline such as sewage and waste water generates sulfuric acid due to sulfur bacteria. To corrode the cement and cause corrosion corrosion.

Deodorizers have been developed to remove odors from sewage and wastewater.The deodorization method includes physicochemical treatment methods such as activated carbon adsorption, ozone oxidation, and combustion deodorization, soil microbial treatment, activated sludge, and biofilters. The biological treatment method of is used.

Deodorizing apparatus for removing odor generated from such sewage and wastewater has been developed, and as an example of the deodorizing apparatus in Patent No. 10-767459, a deodorizing apparatus for deodorizing odor by using microorganisms in a fixed carrier Patent No. 10-331725 discloses a resin composition containing an iron (II) compound, a chelating agent, and a porous material. Patent No. 108299 discloses a ceramic fiber, the surface of the ceramic fiber, and a ceramic composition. Disclosed is a deodorizing catalyst comprising a fine zeolite powder supported on a gap of fibers, mainly a gold and iron oxide supported on the fine zeolite powder, and shaped to allow gas to pass therethrough.

In addition, Patent No. 10-1050165 shows that spore-like native microbial colonies are activated through germination and propagation through spores under conditions in which oxygen and organic matter are supplied, and further promote activation of native microorganisms returned from the secondary deodorization tank. Indigenous microbial activators designed to; A first deodorizing tank for first removing odorous substances from a to-be-processed object which has passed through the native microorganism activating tank under conditions in which oxygen and activated native microorganisms are continuously supplied; And odorous substances are removed from the to-be-processed object which passed through the 1st deodorization tank under the conditions which continuously supply oxygen and an activated native microorganism.

However, various treatment methods have been disclosed, such as the deodorizer, but in the case of odor, there are various causes, so it is difficult to remove the complex odor by one removal mechanism, and in particular, the sulfur compound contained in the odor component is not sufficiently deodorized. Since there have been many cases of being discharged as it is, there is a continuing need for a new deodorization method capable of removing odors containing sulfur compounds that are discharged without being removed by being added to a conventional deodorizer.

In order to solve this problem, the present invention allows the contaminated external air containing the malodorous component to be introduced into the reactor by the suction fan, and the sulfur compound contained in the malodorous component in the reactor is brought into contact with the catalyst injected through the injection nozzle to react.

The catalyst spray nozzle is installed at a lower portion adjacent to the inlet of the reactor and is connected to the catalyst storage tank and the catalyst transfer pipe to inject the catalyst supplied by the transfer pump, but the catalyst spray nozzle is installed in multiple stages in the vertical direction. It is characterized in that the desulfurization is made to increase the contact efficiency between the contaminated external air and the catalyst injected into the multi-stage formed in each of the vertical tubular reactor.

The catalyst spray nozzle is sprayed by atomizing the catalyst into fine particles in such a way that the spray is installed through the three outlet grooves that are curved in the rotational direction on the side wall of the rotary spraying body installed between the rotating shaft portions located above and below. Characterized in that it is made.

The storage tank stores the catalyst for removing sulfur compounds to be supplied to the catalyst spray nozzle and recovers the desulfurization catalyst used in the reactor, but connects an auxiliary transfer pipe to the lower sidewall of the storage tank to remove the sulfur compound from the desulfurization catalyst through the circulation pump. After passing through the filter for separating the sulfur compound is characterized in that the cyclic drop in the upper portion of the storage tank so that the catalyst can be regenerated by the oxidation reaction in contact with the air.

Deodorizing device of the present invention is to remove the odor generated in the sewage and waste water can be added to the normal deodorizer to remove the sulfur compounds contained in the polluted outside air environmentally and effectively to increase the deodorization efficiency.
