With the rapid development of the power industry, wastewater generated during the power production process is also increasing. These wastewaters contain a large amount of oil, suspended solids, organic matter and other pollutants. If not effectively treated, they will cause serious pollution to the environment. Therefore, power sewage demulsifier is a good solution to the problem.
As a new type of wastewater treatment agent, power wastewater demulsifier has multiple functions such as demulsification, oil removal, decolorization, and flocculation. It can effectively remove oil and suspended solids in power wastewater and improve the treatment effect and compliance rate of wastewater. .
Characteristics of power sewage demulsifier:
1. Efficient demulsification: The power sewage demulsifier can quickly destroy the stability of the emulsion and separate the oil droplets from the water to achieve the purpose of demulsification.
2. Good oil removal effect: The power sewage demulsifier can effectively remove oil pollutants in wastewater, reducing the oil content of wastewater to below the national discharge standard.
3. Remarkable decolorization effect: The power sewage demulsifier can remove the color of the wastewater and make the color of the wastewater clear and transparent.
4. Strong flocculation effect: The power sewage demulsifier can condense suspended solids and colloidal substances in the wastewater into larger particles, which facilitates subsequent sedimentation and filtration treatment.
5. Easy to use: The power sewage demulsifier is easy to use, just add it to the wastewater and stir evenly.
6. Environmental protection and safety: The power sewage demulsifier is an environmentally friendly and safe agent that will not cause harm to the environment and human body.
The working principle of power sewage demulsifier mainly includes the following aspects:
1. Reduce surface tension: Electric sewage demulsifier can reduce the surface tension between oil droplets and water, making it easier for oil droplets to separate from water.
2. Destroy the emulsification film: The power sewage demulsifier can destroy the emulsion film in the emulsion, causing the oil droplets to lose protection, thereby achieving the purpose of demulsification.
3. Neutralize charges: Electric sewage demulsifier can neutralize the charges on the surface of oil droplets, reducing the repulsive force between oil droplets, thus promoting the agglomeration and separation of oil droplets.
4. Adsorption and bridging: The power sewage demulsifier can be adsorbed on the surface of oil droplets and suspended solids, forming an adsorption bridging effect, so that the oil droplets and suspended solids can condense into larger particles to facilitate subsequent sedimentation and filtration processing.
Electric power sewage demulsifier is mainly used in the following fields:
1. Thermal power plants: Thermal power plants will produce a large amount of oily wastewater during the production process, such as boiler drainage, turbine condensate, chemical water treatment wastewater, etc. This wastewater needs to be treated before it can be discharged into compliance with standards. The power sewage demulsifier can effectively remove oil and suspended solids in wastewater, improving the treatment effect and compliance rate of wastewater.
2. Nuclear power plants: Nuclear power plants produce a large amount of radioactive wastewater during the production process, and these wastewaters need to undergo strict treatment before being discharged. The power sewage demulsifier can effectively remove radioactive substances and oil pollutants in wastewater, improving the treatment effect and compliance rate of wastewater.
3. Hydropower station: Hydropower station will produce a large amount of sediment-containing wastewater during the production process, and this wastewater needs to be treated before being discharged. The power sewage demulsifier can effectively remove sediment and suspended solids in wastewater, improving the treatment effect and compliance rate of wastewater.
4. Electrical equipment manufacturing enterprises: Electrical equipment manufacturing enterprises will produce a large amount of oily wastewater during the production process, such as mechanical processing wastewater, cleaning wastewater, etc. This wastewater needs to be treated before it can be discharged into compliance with standards. The power sewage demulsifier can effectively remove oil and suspended solids in wastewater, improving the treatment effect and compliance rate of wastewater.
The use of power sewage demulsifier mainly includes the following steps:
1. Determine the dosage of the chemical: Determine the dosage of the power sewage demulsifier according to the water quality and treatment requirements of the wastewater. It is generally necessary to conduct a small test first to determine the specific dosage ratio.
2. Prepare the pharmaceutical solution: Add the power sewage demulsifier to an appropriate amount of water, stir evenly, and prepare a pharmaceutical solution.
3. Add wastewater: Add the prepared pharmaceutical solution to the wastewater and stir evenly to fully mix the pharmaceutical and wastewater.
4. Reaction time: Determine the reaction time according to the quality of wastewater and treatment requirements. Generally speaking, the reaction time is 10~30 minutes.
5. Precipitation filtration: After the reaction is completed, the wastewater is subjected to sedimentation filtration to remove oil and suspended solids in the wastewater.
As a new type of wastewater treatment agent, the power wastewater demulsifier has the advantages of efficient demulsification, good oil removal, significant decolorization, strong flocculation, easy use, environmental protection and safety, and can effectively remove oil in power wastewater. and suspended solids to improve the treatment effect and compliance rate of wastewater. With the continuous development of the power industry, the application prospects of power sewage demulsifiers will become increasingly broad.
