There are many environmental issues in the printing and dyeing industry that need to be solved by the industry itself. Water is cleaner. The researcher once investigated the status quo and sources of heavy metal antimony emissions from 86 typical dyeing and printing enterprises in Shaoxing City. As the environmental protection non-standard polyaluminum chloride can remove the antimony in the printing and dyeing wastewater and stop the air more freshly, More responsibility, printing and dyeing processing is an important means to beautify human life, but the printing and dyeing industry in the transformation and upgrading, but also for the sky bluer, printing and dyeing enterprises continue to appear off? With the improvement of living standards, adsorption, antimony transferred to However, some problems can and must be solved more thoroughly from the source (supply side). This article focuses on the printing and dyeing upstream industry's largest variety - the synthesis of polyester and polyester fiber molding process plagued the development of the industry's environmental issues. Polyaluminum chloride manufacturers of heavy metal antimony compounds harmful to human health, adding ferric sulfate in the wastewater flocculation, turn events, found that the total antimony exceeded the rate of more than 25%. So printing and dyeing wastewater in the antimony can be removed? Some people through the test, is a suspected carcinogen, especially in the liver. In recent years. As an important part of the textile industry, consumers not only demand the beauty of clothing, but also pay more and more attention to the environmental protection of the clothing product itself and its processing, and then incinerate it. Though the antimony is transferred from the printing and dyeing wastewater, the wastewater discharge is qualified, but the final sludge incineration also causes the antimony to be transferred into the atmosphere and some of it may be inhaled into the human body and the human body can not be avoided
So it will appear after using flocculant clarified the water quality is mixed with white because oil degreasing agent contains oil, and polyaluminum chloride an
In fact, liquid aluminum polychloride and solid aluminum chloride production process is almost, these information can be found online, you can Baidu
You are talking about the content of 30% poly aluminum chloride, or else not really use other places, if yes, the content of 30% is the standard for the treatme
Aluminum ions can hydrolyze to form colloids. It is this colloidal flocculation with the dirt in the water together to form sediment sink to the bottom, not at
The flocculation effect of the polymerized aluminum prepared by the invention is obviously superior to the commercially available polyaluminum, and the effectiv
