Detailed Description

A plurality of digestion degradation rods 3 are arranged in a treatment tank 1 with an inlet 2 at one side of the upper end, an aeration pipe 4 is arranged at the lower part of the digestion degradation rod, an electric heater 5 is arranged at the lower part of the aeration pipe, a temperature controller 7 is connected at one side of the electric heater, a water collecting tank 6 is arranged at the lower part of the electric heater, a water seepage discharge pipe 8 is arranged at the bottom of the water collecting tank, and a gate valve 9 is arranged on the water seepage discharge pipe.

The digestion degradation rod is an edible mushroom culture medium rod body and is of a porous structure, and a mushroom culture medium rod is preferably selected.

The working process is as follows:

closing a gate valve of the water seepage discharge pipe, then injecting soybean milk wastewater into the treatment tank through the inlet until the treatment tank is full of the soybean milk wastewater, soaking the digestion degradation rod, turning on a power supply of the temperature controller and a power supply of the electric heater to enable the electric heater to work and heat up, controlling the temperature in the treatment tank to be between 30 and 50 ℃, digesting and degrading organic substances adsorbed and attached on the digestion degradation rod by fungi and bacteria remained in the digestion degradation rod, absorbing and propagating organic substances of biological reaction in the digestion degradation rod by the fungi or bacteria, digesting and degrading the organic substances in the soybean milk wastewater and adsorbing the organic substances on the digestion degradation rod, then the aeration pipe aerates the treatment tank, air or oxygen oxidizes the digested and degraded organic matters to oxidize and purify the treated soybean milk wastewater, and then a gate valve on a water seepage discharge pipe is opened to discharge clean water in the treatment tank. When one cycle of treatment is finished, the digestion and degradation of the soybean milk waste water are carried out for another cycle. And when the discharged clear water is turbid, taking out the digestion degradation rod from the treatment tank, reloading the digestion degradation rod into a new edible fungus culture medium rod, and carrying out the digestion degradation treatment on the soybean milk wastewater again to adsorb and digest and degrade cured substances, organic substances and metal salts, and separating out the clear water to achieve the purpose of purifying the soybean milk wastewater.

In summary, after the soybean milk wastewater is cultured for a period of time at a specific temperature in the treatment tank, the soybean milk organic matter is aerated, the decomposed product and the clear water are separated, and the clear water is gathered in the water collection tank and discharged from the water seepage discharge pipe. The water seepage is clear water seeped out of gaps of the edible fungus culture medium, and the principle of the seeped clear water is the same as that of the seeped clear water of mountains.

The technical principle is as follows:

the soybean milk waste water contains non-flocculated protein, carbohydrate and a flocculation curing agent, is in a semi-viscous state, and can escape hydrogen sulfide gas after natural storage, because the protein contains sulfur, the protein is decomposed to generate hydrogen sulfide, and the hydrogen sulfide diffuses in the air to generate odor and is toxic. In the soybean milk wastewater, protein coagulates, and a large amount of biological organic matters such as carbohydrates in the soybean milk wastewater remain, so that the soybean milk wastewater is difficult to filter and remove again. In addition, a flocculating agent is used for forming the bean product, the commonly used flocculating agent comprises magnesium chloride, gypsum or glucose lactone, and the flocculating agent or the curing agent remained in the soybean milk wastewater is dissolved in the soybean milk wastewater, so that the environment is greatly polluted if the soybean milk wastewater is not treated.

The digestion refers to the ablation of biological organic matters under the action of microorganisms, and the degradation refers to the degradation of the biological organic matters into simple molecular chains after the digestion under the action of the microorganisms.

The mushroom culture medium in the edible fungi is wood powder, the edible fungi are produced after the edible fungi are inoculated with spores of the edible fungi and cultured, the mushroom culture medium after the edible fungi are picked is of a rod-shaped structure and can be infected and propagated by the bacteria in the later period of culture, the bacteria mainly comprise complex fungus groups such as mould fungi, actinomycetes and the like, so that enough organic matter digestion and degradation capability is obtained in nature, and the digestion and degradation effect of the organic matter is good by using the edible fungi culture medium rods as a treating agent. The treating agent is preferably Lentinus Edodes culture medium or other edible fungi culture medium.

The soybean milk waste water contains protein flocculant, also called firming agent, wherein magnesium chloride and calcium sulfate are metal salts, and form a mixture with organic matters after digestion and degradation, so that the activity of the mixture is reduced, and the mixture is also solidified biologically, and therefore, the mixture cannot diffuse into the air in the form of hydrogen sulfide.

The processing flow by using the device is as follows: soybean milk waste water-edible fungus stick culture medium fermentation-organic matter digestion degradation-adsorption-filtration-clear water exudation-clear water discharge-solid waste removal.

Compared with the prior art:

the existing biological wastewater treatment usually adopts a biochemical tank, utilizes strain propagation to purify wastewater, has long treatment period, is easy to die strains, has poor activity of common strains, does not directly adopt a temperature heating device, and does not directly carry out aeration treatment, so the treatment effect is poor. The edible fungus culture medium rod is used as a treating agent, abundant floras are used for purifying the soybean milk wastewater, and the edible fungus culture medium rod is used as a carrier to play a role in digesting attachment of degradation products. Compared with the application, the method has the advantages that the treatment speed is high, the adsorption and purification effects can be realized, the distinguishing characteristics are obvious, the effect is positive, and the patent three-property principle is realized.

The innovation points are as follows: the treatment tank is used as a treatment container, the edible fungus culture medium rod is used as a treatment agent and a carrier, the treatment tank is heated by an electric heater, and oxygen is introduced into the treatment tank by an aeration pipe for oxidation, so that the soybean milk wastewater is treated.

The method is characterized in that:

in order to digest and degrade soybean milk wastewater with complex components, a semi-fermented mushroom culture medium rod is used as a treating agent, comprises microorganisms and a carrier, and plays a role in digestion and degradation.
