Insiders know that the current market is very good shell activated carbon, investigation found that mainly used in the factory to remove waste water, wastewater in the factory contains a variety of substances exceeding the standard, the columnar carbon purification effect is so good, it can mainly treat the waste water what substances?
To this end, the survey was conducted through interviews, questionnaires and telephone calls, and the results are as follows:
1. Treatment of dye wastewater with columnar activated carbon
The development of textile industry has led to the development of dye production. The survey shows that a large amount of dyeing wastewater is produced every year.
Dye wastewater has deep chroma, large concentration, complex composition, large water quality variation, and is difficult to be treated. The chroma of water affects the photosynthesis of aquatic plants, thus destroying the ecological balance of water.
Its large specific surface area enables it to effectively remove the chroma of waste water.
2. Treatment of pesticide wastewater with columnar activated carbon
In the process of pesticide production, raw materials, synthetic process and chemical structure of products are different, and a lot of waste water is discharged in the production process.
Pesticide wastewater has high organic concentration, high toxicity, poor biodegradability and complex composition.
The columnar carbon can effectively adsorb pesticide wastewater and various toxic substances in herbicide wastewater.
3. Treatment of electroplating wastewater with columnar activated carbon
With the rapid development of electroplating industry, a large number of electroplating wastewater is produced.
There are a lot of CrVI in the waste water of chromium electroplating. If it is discharged directly without treatment, it will seriously pollute the environment on which human beings live.
Columnar carbon has developed microporous structure so that it has a strong physical adsorption capacity to effectively adsorb CrVI in waste water. Meanwhile, a large number of oxygenated groups on the surface of columnar carbon have the electrostatic adsorption function to generate chemical adsorption on CrVI, which can be completely used to treat CrVI in electroplating waste water.
4. Columnar activated carbon treatment of cyanide containing wastewater
The coking industry, blast furnace gas washing, electroplating industry, gold and silver ore dressing and other industries discharge cyanide wastewater.
Cyanide is highly toxic to humans and fish.
Columnar carbon has a large specific surface area so it has a good adsorption effect on cyanide containing wastewater
5. Treatment of mercury-containing wastewater with nut shell activated carbon
In the chlor-alkali industry, mercury is used as a negative electrode to produce chlorine gas and caustic soda polyvinyl chloride, acetaldehyde, vinyl acetate. The synthetic industry USES mercury as a catalyst. The electronic instrumentation industry also USES mercury, so these industries discharge mercury-containing wastewater.
Mercury has a serious toxic effect on human body, in which methylmercury accumulates in human brain tissue and invades the central nervous system to destroy the nervous function, leading to death.
Columnar carbon can effectively adsorb mercury in wastewater.
The above is a summary of the columnar carbon commonly treated several types of wastewater, in fact columnar carbon can also adsorb many other organic substances, customers can choose suitable for their own.
PUDA carbon packer:
DCS-FWZL series packing machine adopts gravity free flowing method. A pneumatically controlled two-position feed gate is used to realize fast and slow feeding materials. When filling weight reaches preset value, feeding system stops running , packing bag will be manually taken off, thus single packing is finished.
