Embodiment Construction

[0021] Below in conjunction with 6 examples the present invention is described in detail, but the present invention is not limited to the given embodiment.

[0022]

[0023] In the embodiment, first mix the EM stock solution, honey and water according to the above volume ratio, then add the plant essence-ethanol mixed solution into the mixed solution, and put it into a rotary mixer with a speed of 120r / min-180r / min under airtight conditions. It is cultivated by anaerobic fermentation in a shaking table for 3-5 days. Measured by the method provided by the NY / T789-2004 standard, the compound biological deodorant prepared in each example has a pH of 3.4-3.5, and the effective number of viable bacteria (cfu) is greater than 100 million / ml.

[0024] During the EM rejuvenation fermentation process, the role of honey is to provide C source and energy for microbial rejuvenation and metabolism. After the microorganism obtains C source and energy, it changes from a dormant state to a...

Abstract

The invention relates to a method for effectively removing odors in refuse landfills or refuse transfer stations, belonging to the technical field of multifunctional biological agents. Compound biological deodorant concentrated solution is obtained by mixing 4-5% of EM (effective microorganisms) stock solution, 3-5% of molasses, 3-5% of plant essence-ethanol mixed solution and 85-90% of water uniformly and putting the mixture into a rotary table at a speed of 120-180r/min to undergo anaerobic fermentation for 3-5 days under the aright condition at room temperature. The compound biological deodorant solution has the advantages of simple preparation process and low cost, does not cause secondary pollution and has a simple and convenient use method and broad application prospect.

Description

[0001] technical field [0002] The invention belongs to the technical field of multifunctional biological preparations. The invention prepares the composite biological deodorizing liquid used in landfills and garbage transfer stations by adding plant essence and using composite microorganism anaerobic fermentation technology. The prepared compound biological deodorizing liquid is released and then sprayed, which can effectively eliminate the malodorous substances in landfills and garbage transfer stations. The compound biological deodorizing liquid has a simple and convenient cultivation process, low invention cost, simple use method and broad application prospects. Background technique [0003] Malodorous substances refer to all gaseous substances that stimulate the olfactory organs to cause people's unpleasantness and damage the living environment. It not only breeds a large number of bacteria that spread diseases, but also directly affects the respiratory system, nervou...
