Description
Technical field
The present invention relates to a kind of human deodorant method, particularly to human feces foul smell deodorant method from the feces slag remover.
Background technology
Human feces is a kind of good organic fertilizer, and the fertilizer that the past often is used as the farmland uses.But because human diet complexity, feces has the stench that is difficult to remove, having a strong impact on peasant's work and living environment, along with the rural area people's living standard improves, and chemical fertilizer is universal day by day, and the peasant does not use human feces gradually, so the city human feces of China is all sent basically into underground webmaster, the human feces in rural area then majority enters irrigation canals and ditches, river, causes environmental pollution.For fear of environmental pollution, much big or middle in recent years city has all adopted the method for chemistry or fermentation to handle the city human feces, but all can overflow foul smell inevitably when feces flows into slag remover, pollutes the working area environment.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly carries out the deodorant method to the human feces foul smell, and its technology is simple, and implementation cost is lower, and deodorization is better.
Solving the technical scheme that technical problem of the present invention adopts is: at first will suck active carbon layer from the foul smell of feces slag remover and carry out part absorption, again to the foul smell by active carbon layer from bottom to top with containing the alkali liquor spray washing, foul smell after the washing fully mixes with essence and flavoring agent liquid, isolate the liquid in the gas at last, gas is discharged.
Technical scheme of the present invention also comprises:
1. spray liquid percentage by weight prescription is:
2. essence and flavoring agent liquid percentage by weight prescription is:
Oleum bergamottae 0.5%～1.5%, methyl phenylacetate 0.5%～1.5%, Herba Menthae quintessence oil 1.5%～2.5%, acetic acid Lignum cinnamomi camphorae brain 0.5%～1.5%, methyl is basic ketone 1.5%～2.5% how, ionoionone 0.5%～1.5%, Oleum Caryophylli 0.5%～1.5%, Herba Pogostemonis oil 0.5%～1.5%, ethyl acetate 1.5%～2.5%, nerol 0.5%～1.5%, glycerol 3%～6%, surplus is the alcoholic solution of 20% concentration.
