Embodiment 1

[0010] Take 100g of orange peel and wash it, crush it with a grinder for 30min, add 500ml of distilled water to soak for 60min, then boil for 30min, filter out the decoction, add 200ml of distilled water to the filter residue and decoct for 30min, combine the two filtrates, and centrifuge at 2500r / min for 20min , take the supernatant, use a rotary evaporator to keep the temperature at 60°C, heat and concentrate the extract to 100ml, and obtain a 100% concentration plant extract deodorant. Dilute the deodorant and water in a ratio of 1:1, which can be used for the deodorization of the sewage lifting pump room.

Embodiment 2

[0012] Take 100g of pomelo peel, wash it, grind it with a grinder for 30min, add 500ml of distilled water to soak for 60min, then boil for 30min, filter out the decoction, add 200ml of distilled water to the filter residue and decoct for 30min, combine the two filtrates, and centrifuge at 2500r / min for 20min , take the supernatant, use a rotary evaporator to keep the temperature at 60°C, heat and concentrate the extract to 100ml, and obtain a 100% concentration plant extract deodorant. Dilute the deodorant and water in a ratio of 1:1, which can be used for the deodorization of the sewage lifting pump room.

Embodiment 3

[0014] Wash 100g of orange peel and pomelo peel according to the mass ratio of 1:1, crush them with a grinder for 60 minutes, add 500ml of distilled water to soak for 90 minutes, then boil for 60 minutes, filter out the decoction, add 200ml of distilled water to the filter residue and decoct for 30 minutes. Combine the filtrates, centrifuge at 3000r / min for 30min, take the supernatant, use a rotary evaporator to keep the temperature at 60°C, and heat and concentrate the extract to 100ml to obtain a 100% plant extract deodorant. Dilute the deodorant and water in a ratio of 1:1.5, which can be used for deodorization in the sludge dehydration room.

Abstract

The invention relates to a plant extract deodorant, in particular to a deodorant using orange peel or shaddock peel as an extracting source. The preparation method comprises the following steps of: cleaning orange peel or shaddock peel, crushing the orange peel or shaddock peel for 30-60 min by using a crusher, adding distilled water, and immersing the crushed orange peel or shaddock for 60-90 min; boiling the solution for 30-60 min, filtering out the decoction, adding distilled water into filter residue, decocting the mixture for 30 min, and merging the filtrates of two times; centrifuging the mixture at 2500-3000 r/min for 20-30 min, taking the supernate, and heating and concentrating the extract to obtain 100% concentration plant extract deodorant by using a rotary evaporator at constant temperature of 60 DEG C. The plant extract is diluted according to different needs. The plant extract deodorant provided by the invention has the characteristics of good deodorization effect, rapid effect taking and no secondary pollution.

Description

technical field [0001] The invention relates to a plant extract deodorant and a preparation method thereof, in particular to a deodorant prepared by using orange peel and pomelo peel extracts. Background technique [0002] The malodorous gas produced in the process of urban sewage treatment is mainly concentrated in the pump room, grit chamber, aeration tank, sedimentation tank and sludge treatment area. The main pollutants include hydrogen sulfide, ammonia and other inorganic substances and low molecular fatty acids, amines, Aldehydes, ketones, ethers, halogenated hydrocarbons and other organic substances. At present, the commonly used methods to deal with industrial odor include water washing, liquid cleaning, activated carbon adsorption, ozone oxidation, electrostatic deodorization, soil deodorization, combustion and biological deodorization; among them, plant extract deodorization It has the advantages of no secondary pollution, low treatment cost, convenient operation ...
