Description
Technical Field
The invention relates to the technical field of chemical product preparation, in particular to a deodorant for treating malodorous gas of sewage containing organic sulfur and organic amines in sewage plants of pharmaceutical enterprises and a preparation method thereof.
Background
With the progress of society, the requirements of people on the living environment are continuously increased. Pharmaceutical and chemical enterprises are indispensable important components of national economy, but the influence of sewage plants on the ambient atmospheric environment cannot be ignored, and governments of the country and all parts have more strict execution standards.
Municipal sewage malodorous gas mainly takes inorganic malodorous gas such as hydrogen sulfide, ammonia and the like as main materials and can be removed by chemical washing such as alkali washing, acid washing and the like; however, the compositions of malodorous gases in sewage plants of fine chemical enterprises are different, and the malodorous gases are mainly heterocyclic compounds, organic amine compounds, long-chain hydrocarbon compounds and the like through links such as a water treatment process and the like under the conditions of certain temperature, humidity, pressure and the like. Through gas-mass chromatography detection, the proportion of the substances in the waste gas is low, but the odor threshold value is high, and through treatment of related deodorization equipment, even if the related emission standard is met, the odor can be emitted, so that the pollution to the surrounding environment is caused to a certain extent.
The existing method for treating the stink of the sewage plant mainly comprises the following steps: biological methods, ionic methods, catalytic methods, incineration methods, adsorption and absorption methods, and the like. However, in many cases, it is difficult to effectively reduce the odor and secondary pollution is easily caused.
At present, a deodorant with good deodorization effect for treating the malodorous gas of sewage containing organic sulfur and organic amines and a preparation method thereof are lacked.
Disclosure of Invention
In view of the above-mentioned defects of the prior art, the technical object of the present invention is to provide a deodorant with good deodorizing effect for treating malodorous gas in sewage containing organic sulfur and organic amines, and a preparation method thereof.
In order to achieve the technical purpose, the invention provides a deodorant for treating malodorous gas of sewage plants of pharmaceutical enterprises, which comprises the following components in parts by weight:
further, the surfactant is sodium laurate or ethoxy sulfate.
Furthermore, the citric acid reacts with dimethylamine to generate amine salt, so that malodorous gas in the exhaust gas can be effectively reduced, and the measurement control can be realized.
The preparation method of the deodorant comprises the following steps:
accurately weighing the components in parts by weight;
and (2) mixing the components in deionized water, fully stirring and heating to 45 ℃.
The invention has the beneficial effects that:
the deodorant provided by the invention has a good deodorizing effect, particularly for malodorous gases in sewage containing organic sulfur and organic amines, can greatly reduce peculiar smell emitted by treated gases in sewage plants of pharmaceutical enterprises, and has good popularization and use values.

test examples
The deodorant prepared by the embodiment is subjected to a deodorization test, and the deodorant prepared by the embodiment is added into a deodorization washing tower of a sewage plant of XX certain pharmaceutical enterprise, so that the effect is good, and the odor of the gas discharged from a chimney is greatly reduced.
The continuous stable operation is carried out for 3 months, the deodorization effect is good, and each component can be increased or decreased according to the actual situation.
The test results show that the deodorant provided by the invention can greatly reduce the peculiar smell emitted by the treated gas of a pharmaceutical enterprise sewage plant, and has good popularization and use values.
When the amount of citric acid and sodium hypochlorite is large, the reaction time with respect to malodorous gases is longest. Can effectively control the foul smell of sewage containing organic amines in fine chemical industry.
