Treatment Technology Of Printing And Dyeing Wastewater By Electrochemical Leather Making

< p > > Description: in industrial waste water, resins, plus < a href= "http://? www.91se91.com/news/index_c.asp" > fat agent < /a > dye and other refractory substances are difficult points in biochemical treatment. In view of these difficulties, biochemical treatment has become the most ideal method nowadays.

< /p >

< p > at present, with the increase of a href= "http:// www.91se91.com/news/index_c.asp" > pollutants > /a > index requirements and the reduction of pollution values, many enterprises fail to meet the requirements of environmental protection after separate treatment or sewage treatment works.

< /p >

< p > new facilities are too expensive to operate.

The result is that electrochemical method is used to further treat the wastewater outlet to meet the emission requirements.

< p > first, recycling is legitimate and groundbreaking.

The activities of cooperation between the brand and the foundation with public offering qualifications have been used to recover old clothes, and have opened up a new legal recycling channel. Especially, many brand owners who have participated in the activity have printed coupons, vouchers and other incentives to encourage donors. This behavior can be regarded as a "paction" between brands and consumers. The brand owners can legally possess the property rights of these old clothes, which is one of the foundations for the brand enterprises to develop their own comprehensive utilization.

< p > two is pparent donation information.

The charitable donation platform for activities is provided by the Youth Development Foundation's "Western warmth program". Every donated old clothes will be traced back to the donated children, and donors can be inquired through the official website.

Some clothing entering the charity supermarket also has traceable information for enquiries.

The collection and feedback of these information will directly reflect the real situation of the reuse of waste textiles in China, where the second-hand clothing trade has not yet been opened.

< p > three is the reuse of donation surplus, which is the focus of the combination of charity and industry.

After maximizing the value of old clothes, after reuse (donation), the remaining old clothes will enter the textile industry for recycling. This link is one of the key activities.

The contents we need to study include sorting, product line design, production and cost estimation. On this basis, we can study the establishment of a benefit feedback model between industry and charity.

< /p >

< p > four is to promote renewable products in other industries.

"Zero abandonment of old clothes" will cooperate with the Automobile Association, building materials Association and other units in the promotion of renewable products to complete the investigation and Research on the use of recycled products.

The promotion of recycled products is the driving force for the formation of the industrial chain, and the government needs to strongly support policies such as encouraging procurement and encouraging consumer application. After the end of the campaign, special policy recommendations will be put forward.
