2 is a schematic diagram of a wastewater treatment plant according to the present invention.

Deodorant according to the present invention includes 10 to 20% by weight of oyster obstruction, 10% to 40% by weight of potassium feldspar, 10% to 40% by weight of ganbanite, 20 to 40% by weight of zeolite and 1 to 3% by weight of aluminum sulfate. .

The following explains each component.

1 is an enlarged photograph of a closed angle (a) before plastic working and a closed angle (b) after incinerated processing. As shown in FIG. 1, the closed angle after plastic working has an irregular pupil of an amorphous form than the closed angle before firing. Prior to firing, the tissues are layered and relatively smooth, but after firing, the outer surface cracks due to thermal expansion. In addition, after firing, CaCO ₃ is converted to CaO because it is decomposed into CaO + CO _2, and CaO is introduced into the water and oxygen atoms are dissociated. The oxidation is removed through oxidation, and some of the oxidation reaction is combined with hydrogen ions (H ⁺ ) in water to form an OH ^- group as shown in Formula 1 to form a strong OH ^- radical.

^{_{CaO + H 2 O → Ca 2+}} + 2OH - ---------- formula

OH ^- Radical is the second most oxidizing agent in the world, after fluorine, more potent than ozone and chlorine, but not toxic to humans. Oxygen atoms and OH ^- radicals, like oxygen atoms, can remove rot and odor-causing substances through oxidation. When more than 20% by weight of the formulation is strongly alkaline and the content of other materials are falling off the deodorizing effect, when less than 10% by weight there is a problem that less calcium components in the sludge used as a fertilizer.

Potassium feldspar is a kind of crude rock mineral, which neutralizes the acidification of sludge precipitated by alkaline feldspar with high K and Na content, and contains a large amount of K and Na which are essential elements for plant growth. In addition, the activity of ion exchange ability is increased through calcining and pulverization, and the adsorption ability with ions is excellent. When less than 10% by weight, the content ratio of K and Na components may be insufficient, and plant essential elements may be insufficient.

Elvan has high emissivity of far-infrared and far-infrared is infrared with a wavelength of 25um or more, which is excellent for removing bacteria, one of the causes of odors in water.

If the elvan is less than 10% by weight, there is a problem of low far-infrared emissivity, and if it exceeds 40% by weight, there is a problem of deterioration due to lack of content of other agents.

Zeolite has excellent CEC (Cation Substitution Capacity) and absorbs ionic substances such as ammonia, hydrogen sulfide, and trimethylamine, which are odor-causing substances.

If the zeolite is less than 20% by weight cation substitution falls, if more than 40% by weight there is a problem in recycling to fertilizer due to the lack of content of other formulations.

Alumina sulfate reacts with alkali in water to form aluminum hydroxide, which is used as a flocculant in the present invention because of its coagulation action. In the present invention, alumina sulfate is used to increase the cohesion of odor-causing substances and contaminant-extinguishing substances adsorbed with acid and pH adjustment to other agents. It is preferable to use 1 to 3% by weight of alumina sulfate in the present invention, but if the amount of alumina is less than 1% by weight, the cohesive force of odor-causing substances and suspended solids decreases, and the deodorization efficiency is lowered. If it exceeds the weight%, the flocculation efficiency is increased, but there is a problem in recycling the deodorization ability and sludge as a fertilizer due to the lack of content of other preparations.

The present invention is to activate the material through the firing of various materials and to increase the specific surface area through the micro-powder to reduce the reaction time and increase the efficiency through which the faster processing time and excellent processing efficiency to increase the economics through cost reduction It can reduce odor, BOD, COD, TN, and TP in the water at the same time.

The formulations prepared above are rich in adsorption oxide minerals SiO 2, Al ₂ O ₃ , Fe ₂ O _3, etc., and have good ion exchange ability with odor causing substances such as ammonia, hydrogen sulfide, trimethylamine, etc. It is rich in alkali metal components such as K and contains a large amount of CaO component which forms oxygen atoms and OH radicals.

As the input method, it depends on the characteristics of wastewater, but add 100ppm ~ 2000ppm when treating livestock wastewater. Most livestock wastewater has a slightly acidic pH after biological treatment, so a rapid stirring of 5 minutes of slow stirring and 10 minutes of precipitation and an hour of precipitation are appropriate. The precipitated sludge of the treated water has a higher porosity than the sludge treated with conventional chemical treatments (alum, PAC, polymer), which can significantly reduce the filter cloth closure during dehydration, thereby increasing the dehydration rate. It can reduce the quality and cost of fertilizer through sterilization and odor removal.

The recycling of the sludge generated by the deodorant according to the present invention to fertilizer will be described in more detail. In general, in order to use as an important fertilizer for plant growth, neutralization and breathability of acidification generated during sludge residence is important. The deodorant according to the present invention is rich in alkaline components to neutralize acidic substances, and the surface area per unit weight of particles is much wider, so that the moisture and nutrient retention is strong, so that the moisture content can be adjusted during fertilizer production, and breathability can be secured. Sludge can be recycled as fertilizer.

That is, the sludge precipitated with the deodorant according to the present invention shows a different shape from the sludge precipitated with the existing chemicals. Sludge precipitated with chemicals causes closure phenomenon in the filter cloth of the dehydrator, so that the dehydration efficiency is low, so that the ratio of excipients (sawdust, etc.) is high, and odors and pathogenic microorganisms are multiplied, making it difficult to use as a fertilizer. The sludge treated with the water treatment agent can reduce the amount of excipients during the housing due to the high dehydration efficiency through the porosity of each component constituting the water treatment agent, and solve the problem of odors and pathogenic microorganisms by deodorizing function and sterilization function and natural minerals as the main raw material. Among the essential nutrients for plant growth, it contains a large amount of potassium (feldspar), phosphoric acid (anodized angle), calcium (anodized angle, zeolite), magnesium (pulse stone), and trace elements iron (feldspar, elvan) and other functional ingredients. In addition, as a fertilizer for plant cultivation due to the various functional ingredients (N, P) contained in the organic matter precipitated in the water by the input of the material It can increase the value.

As described above, the deodorant according to the present invention can be efficiently removed odor without secondary pollution by suppressing re-injury of precipitated sludge and induced natural decomposition through oxidizing agent, while recycling the generated sludge as a fertilizer sludge The treatment problem was solved.

Next, the manufacturing method of the deodorant which concerns on this invention is demonstrated.

Each material is pulverized more than 325 # after firing to increase the specific surface area to increase the adsorption and anion generating ability.

Oyster shells are dried for 5 to 10 days after washing to remove salt, and then calcined at 1,200 ℃ to remove impurities. This is done by making separate the main component of CaCo ₃ with CaO + CO ₂ to calcium oxide, does not reach the decomposition temperature of the reaction does not take place

The calcination of potassium feldspar is fired at 600 ° C, which removes impurities and activates the multi-layered porous function of the material and the activation of Na and K components significantly when fired at less than 600 ° C.

Elvan is processed at 600 degrees to remove impurities and increase far-infrared emissivity.

Zeolite is fired at 400 degrees to remove impurities and maximize voids.

Aluminum sulfate is micronized above 325 # in order to have a fast reaction of powdered aluminum sulfate.

The individual materials produced through the above process are 10 to 20% by weight, 10 to 40% by weight of feldspar, 10 to 40% by weight of ganbanite, 20 to 40% by weight of zeolite and 1 to 3% by weight of aluminum sulfate. Mix evenly to complete the deodorant according to the invention.

The first stirrer 230 is installed inside the first stirrer 200, which is installed to forcibly mix the treated water and the deodorant, which rotates at a higher speed than the slow stirrer described later. The rotation speed of the first stirrer 230 is preferably rotated at a speed of 150 ~ 250RPM. If the rotational speed is less than 150RPM, there is a problem of chemical mixing, and if the rotational speed exceeds 250RPM, there is a problem in the wastewater reaction.

The first stirring bath outlet 220 is a place where the treated water containing the deodorant after the first coagulation reaction is finished in the first stirring bath 200 is discharged, and is preferably installed on the sidewall of the first stirring tank 200. Do.

The second stirring tank 300 agitates the treated water which has been firstly agglomerated in the first stirring tank 200 at a slower speed than the first stirring tank 200, so that the floc is agglomerated in the second reaction between the treated water and the deodorant. And part for maximizing the efficiency of adsorption. That is, the second stirring tank 300 agitates the treated water including the deodorant at a low speed to increase the aggregation and adsorption efficiency by the deodorant. It is composed of a second agitator inlet 310, a second agitator 330, a second agitator outlet (320).

The second stirrer inlet 310 is connected to the first stirrer outlet 220, which is preferably installed at an upper sidewall like the first stirrer outlet 220. That is, the treated water in the first agitator 200 is naturally moved to the second agitator 300 through an upper portion of the sidewall where the first agitator 200 and the second agitator 300 contact each other.

The second stirrer 330 is operated at a lower speed than the first stirrer 230, and is preferably operated at a speed of 25 to 75 RPM. If it is less than 25 RPM, there is a problem of coarsening of wastewater, and if it exceeds 75 RPM, there is a problem of breaking the floc.

The second stirring tank outlet 320 is a place where the treated water after the reaction in the second stirring tank 300 flows out, which is preferably installed at the lower side of the side wall as opposed to the first stirring tank outlet 220.
