Abstract
The invention provides a method for removing combustible toxic and harmful gases in production sewage, wherein the sewage containing combustible toxic and harmful gases generated by a production device is uniformly discharged into a waste water stripping tower, the production sewage is stripped by nitrogen under the condition of normal pressure, the combustible toxic and harmful gases in the waste water are stripped and then sent to a deodorizing device for absorption treatment and then discharged after reaching the standard, and the production sewage subjected to gas stripping is discharged to a sewage treatment plant for treatment.
Description
Technical Field
The invention relates to the field of liquid gas stripping, in particular to a method for removing combustible toxic and harmful gases in production sewage.
Background
Chemical industry manufacturing enterprise can produce the production sewage that has certain pressure in process of production, contains a certain amount of flammable poisonous and harmful gas in the production sewage that produces, if do not directly discharge to sewage treatment plant through handling, the flammable poisonous and harmful gas that contains in the production sewage is released at sewage treatment plant to produce harm to sewage treatment plant's operating personnel, consequently, get rid of the flammable poisonous and harmful gas in the production sewage, have very important meaning to chemical industry enterprise's safety in production.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a method for removing combustible toxic and harmful gases in production sewage.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for removing combustible toxic and harmful gases in production sewage specifically comprises the following steps:
step 1: collecting the production sewage into a waste water stripping tower;
step 2: nitrogen is filled into the wastewater stripping tower to strip the production sewage, combustible, toxic and harmful gas extracted by the gas is gathered at the top of the wastewater stripping tower, and the stripped production sewage is discharged from the bottom of the tower to a sewage treatment plant for treatment;
and step 3: the top of the waste water stripping tower is connected with a deodorizing device through a pipeline, and the combustible toxic and harmful gas extracted by the gas is absorbed and then discharged after reaching the standard.
Further, the ratio of the amount of the nitrogen gas to the amount of the produced sewage in the step 2 is 1: 20.
Compared with the prior art, the invention uses nitrogen to carry out air stripping on the production sewage under the condition of normal pressure, the combustible toxic harmful gas in the sewage is extracted and then sent to the deodorization device for absorption treatment, and the production sewage after air stripping is discharged to the sewage treatment plant for treatment, thereby reducing the harm to the operators of the sewage treatment plant and the surrounding environment.
Description of the drawings:
FIG. 1 is a schematic diagram of the stripping process of the process wastewater of the present invention.
Detailed Description
The present invention will be described in further detail with reference to specific examples. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the protection scope of the present invention is not limited to the embodiment.
The embodiment of the invention provides a method for removing combustible toxic and harmful gases in production sewage, which comprises the following steps:
step 1: collecting the production sewage into a waste water stripping tower;
step 2: nitrogen is filled into the wastewater stripping tower to strip the production sewage, combustible, toxic and harmful gas extracted by the gas is gathered at the top of the wastewater stripping tower, and the stripped production sewage is discharged from the bottom of the tower to a sewage treatment plant for treatment;
and step 3: the waste water stripping tower is connected with a deodorizing device through a pipeline for subsequent treatment.
Further, the ratio of the nitrogen gas amount to the produced sewage amount is 1: 20.
In the embodiment, the nitrogen gas stripping method is adopted to remove combustible toxic and harmful gas contained in the production sewage, so that the production sewage subjected to gas stripping does not contain combustible toxic and harmful gas, and the harm of the production sewage to operators of sewage treatment plants is reduced.
Claims (2)
