Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a deodorizing apparatus for deodorizing a deodorizing gas,

The present invention relates to a method and a device for passing odorous gas through a plurality of eco-friendly composite deodorizers having a single chemical structure, a wet cleaning unit, first and second biofilter units, and disinfection cleaning units, Friendly composite deodorizing apparatus capable of performing a deodorizing process.

The odor components generated in the sewage treatment plant, the food treatment plant, the livestock wastewater treatment plant, the sludge incineration and drying facility, the landfill, and the various chemical plants have a wide variety of contaminants depending on the source and source. , Sulfur compounds such as mercaptans, nitrogen compounds such as ammonia and amines, volatile organic compounds (VOCs) such as benzene, toluene, ethylbenzene and xylene, and volatile sulfur compounds.

The above-mentioned odorous components are generally converted into water and carbon dioxide to be removed. Generally, odorous gas treatment techniques currently used include physicochemical deodorization methods such as activated carbon absorption method, chemical solution cleaning method, ozone oxidation method, There is a biological deodorization method such as a treatment method, an activated sludge method, and a biofilter.

These methods may be used alone or in combination of two or more depending on the treatment environment. However, the physico-chemical deodorization method has problems of operating costs such as chemicals and material costs, and the biological deodorization method requires a lot of area, There is a disadvantage in that a high cost is required due to a high loss.

In recent years, there has been a growing interest in a method for deodorizing charged microorganisms using a microorganism carrier capable of operating at a small cost in a small space among the biological deodorization methods at a low cost and having high deodorization efficiency.

A method of deodorizing a carrier-loaded microorganism is a method of filling a carrier immobilizing microorganisms in a packed column and removing odor gas by introducing the odor gas into the packed column. The introduced odor gas is decomposed by microorganisms, It is the principle that the odor component is decomposed and removed by keeping the growth by using microorganism.

The biological method using microorganisms as described above has been mainly used for general wastewater treatment, but recently it has been applied to the field of odor removal and its utilization has been increasing.

Treatment techniques in this atmospheric field are focused on stabilizing the microorganisms by immobilizing them in a carrier at a high concentration and cultivating them stably. These microorganisms require the supply of water and nutrients for growth and proliferation, In the case of the apparatus, it is very important to prevent the microorganisms growing on the carrier from being chemically impacted due to a sudden change in the component of the incoming odor gas.

As an example of the chemical shock, a rapid change in the pH of a hydrogen ion causes a deterioration in the malodor decomposition efficiency of the microorganism, induces the mortality of the microorganism, accelerates the change of the hydrogen ion index continuously, ≪ / RTI >

If more than the incoming hydrogen sulfide (H ₂ S) sulfur-containing odors that 30ppm reacts with oxygen and sulfuric acid (H ₂ SO ₄₎ is generated and, when 50ppm or more of a high concentration of hydrogen sulphide flows pass, which microorganisms are fixed and the growth substrate There is a problem that the deodorizing function is stopped until the carrier microorganisms are killed due to high acidity and the microorganisms are re-inoculated.

In addition, ammonia (NH ₃ ) introduced reacts with water to produce ammonium hydroxide (NH ₄ OH), which is alkaline and converted to hydroxylamine (NH ₂ OH) by microorganisms, Depending on the concentration of ammonia, the pH of the deodorizing device is changed and the microbial growth environment is changed, thereby adversely affecting microorganisms.

In order to solve such a problem, the present inventor has proposed in Korean Patent No. 1009339 a pretreatment / deodorizing device of chemical cleansing type at the front end of the deodorizing device, so that the high concentration of acidic and alkaline odor components contained in the collected odor gas The present invention relates to a deodorizing device for biofilter which enables the microorganisms to grow in an optimal environment by neutralizing and removing the biofilter in a growing stage.

The present invention is characterized in that two filter portions composed of a polyurethane foam layer and a poling layer are provided in a pre-main stage body in which a porous ceramic carrier layer and a limestone layer in which microorganisms are fixed and grown, and the two first and second filter portions are connected in series A pretreatment unit configured to supply acidic water to the first filter unit and alkaline water to the second filter unit.

The device neutralizes and removes alkaline and acidic odors before the microorganisms decompose and remove the odor components, thereby reducing the chemical impact and load of the microorganisms growing on the ceramic support layer, thereby improving the efficiency of removing odor components of the microorganisms to provide.

However, the malodorous constituents vary greatly depending on the source, and the types of microorganisms that remove the malodorous constituents vary according to the types of the malodorous components. Also, since the optimal growth conditions of the microorganisms differ from one microorganism to another, It is difficult to keep all of the microorganisms, which are different from each other under the optimal growth conditions, in the best active state.

Therefore, as a biological deodorization method, in order to remove the odor component more efficiently, it is necessary to maintain a growth environment condition of the microorganism and to create a growth environment in which each microorganism can maintain the best active state.

A deodorizing device corresponding to this need is disclosed in Patent Registration No. 10-1183090, which is patented and patented by the present inventor.

In the deodorizing device, when the complex odor gas is removed by the biofilter method, the kind of the microorganisms decomposing the complex odor gas is selectively applied according to the kind of the odor component, and the odorous gas can be efficiently removed by optimizing the growth conditions for the microorganisms It is a complex bio-deodorizing device.

The above-described composite bio-deodorizing apparatus includes a blowing fan for sucking odorous gas and blowing air into the apparatus; The water-soluble odor component and the particulate matter of the odor gas are contacted with the washing water in a cocurrent flow while the odor gas passes downward through the poling layer in order to pretreat the odor gas introduced from the blowing fan before decomposing and removing the odor gas from the blowing fan A wet cleaning agent to be removed; A washing water supply tank circulating the washing water from the wet washing part to the wet washing part; While the odor gas introduced from the wet cleaning section passes through the porous ceramic carrier layer in which the limestone layer and the microorganisms are fixed and grown up sequentially, the acid component of the odorous gas contacts with alkaline water and countercurrent flow to neutralize the alkaline water A first bio-filter part in which odorous gas is decomposed and removed by a microorganism controlled by a growth environment, and a porous ceramic support layer and a limestone layer in which odor gas introduced from the first bio- And a second bio-filter part composed of a second bio-filter part in which the alkaline component of the malodorous gas is neutralized by being in contact with the acidic water while passing downward, and the malodorous gas is decomposed and removed by the microorganism whose growth environment is controlled by the acidic water. An alkaline water supply tank for introducing alkaline water from the first bio-filter portion of the bio-filter portion to the first bio-filter portion after the hydrogen ion exponent is regulated; An acidic water supply tank for supplying acidic water from the second bio-filter part of the bio-filter part to the second bio-filter part after regulating the hydrogen ion exponent; A chemical liquid cleaner for removing a malodorous component of the malodorous gas from the biofilter and flowing the cleaned gas upward while passing through the pollution layer, wherein the acidic component and the unchallenged component are removed while contacting the chemical liquid and the countercurrent; And a chemical liquid supply tank for introducing the chemical liquid from the chemical liquid cleaning unit and supplying the chemical liquid cleaning unit to the chemical liquid cleaning unit.

However, in the above-described deodorizing device, the odorous gas continuously flows in the wet cleansing portion, and soluble odorous odors are dissolved in the odorous gas, resulting in a phenomenon in which the pH of the wet cleansing portion is drastically lowered, (PH 0.5 to 2) due to the microbial activity in the biofilter portion, and the piping or tanks of the stainless steel material associated with the biofilter portion Or the tanks are further corroded or damaged, and that the acidic component and the alkaline component of the odor gas flowing into the wet-formed portion become uneven, so that the microorganisms inoculated in the subsequent bio-filter portion digest these components excessively, This leads to the problem of dead.

In addition, in the deodorizing apparatus described above, since the pump is immersed in each of the supply tanks, resistance to strong acidic or alkaline water stored in each of the supply tanks is not sufficient, causing breakage and failure.

In addition, in the above-described deodorization apparatus, various kinds of microorganisms such as Bacillus are fixed to a ceramic carrier and grown in each of the first and second biofilter units, so that various kinds of microorganisms are inoculated in a complex manner to cause trouble between microorganisms There is a problem that the deodorization efficiency is lowered.

Further, in the deodorizing apparatus described above, the water in each processing section is passed to the next processing section through the odor gas flow port by the strong wind force of the blowing fan, and the water in the previous processing section is deficient and drained by the excessive water in the next processing section There are problems that waste water.

The present invention has a problem in solving the above-mentioned problems.

The present invention relates to a structure in which malodor gas passes sequentially through a first and second bio-filter sections and a disinfecting wash section in which a chemical solution washing section, a wet washing section and a discontinuous microorganism are individually inoculated, The above-described problems can be solved by providing the environmentally friendly composite deodorizer with a structure in which a demister or an eliminator is interposed in the flow port between the washing section, the washing section, the first and second biofilter sections, and the disinfection washing section.

In addition, the water is moved to the next treatment unit in each treatment unit provided in the treatment unit by the demister or the eliminator and the water separation unit interposed in the flow ports Can be prevented.
