Membrane Technology Is Highly Sought After By Zhejiang Printing And Dyeing Enterprises.

Physicochemical and biochemical treatment is currently in Zhejiang province. Shaoxing The average water treatment cost per ton is between 1.5 yuan and 2 yuan, which is widely used in dyeing and printing enterprises. In the same treatment of one ton of printing and dyeing wastewater, the cost of membrane treatment technology is as high as 4.6 yuan. Shaoxing's printing and dyeing enterprises, which are renowned for their shrewdness, are now doing this "losing business". They have launched the printing and dyeing wastewater treatment technology project and become a new bright spot in the industry.

Membrane technology is highly sought after.

Recently, in the Binhai Industrial Area, "Sheng Xin Printing and dyeing", in the more than 1000 square meters of open space, construction workers are heading for the hot sun to install new equipment. "This is a new technology of reclaimed water reuse. Membrane treatment Technology. " Sheng Xin dyeing and printing company personnel said that the whole set of equipment is expected to be put into operation in late August.

It is reported that in the past 3 months, "BELLE" and "BELLE Heng" and other 5 printing and dyeing enterprises have signed a technical cooperation agreement with the Ningbo branch of ordnance Technology Research Institute. "Shaoxing printing and dyeing enterprises are very interested in the membrane processing technology and the way of" third party "management cooperation. Apart from the signing of these 5 enterprises, there are still many enterprises actively contacting us, consulting and negotiating. The Ningbo branch of ordnance Technology Research Institute disclosed that due to the sharp increase in Shaoxing business, they have rented office space in Binhai Industrial Area, and are ready to set up offices to meet the needs of business development.

In addition to cooperating with the Ningbo branch of the ordnance Technology Research Institute, many printing and dyeing enterprises also introduced advanced membrane treatment technologies abroad, such as "Zhi Ren printing and dyeing" to invest 8 million yuan to expand and transform the printing and dyeing wastewater treatment system and deep water reuse deep treatment, using Dow's reverse osmosis membrane technology, which is planned to be put into operation in September.

Double effect of water saving and emission reduction

There are so many printing and dyeing enterprises hot film technology, it is reported that 3000 tons of pretreatment wastewater after membrane treatment, 2000 tons can be directly become clean water. It is reported that the company sent special personnel to Suzhou, Ningbo and other places after the inspection, finalized the enterprise to adopt membrane treatment technology. This technology is not only emission reduction and water saving, but also meets the requirements of energy saving and emission reduction. And for enterprises, this economic account can only be earned.

Take the Sheng Sheng dyeing and printing wastewater treatment technology project as an example, the concentration of COD in the treated water is reduced to less than 50mg/L, while the concentration of COD in the river water is about 100mg/L, so it can be reused in industrial water. According to the industrial water price of 1.15 yuan per ton, the average sewage discharge cost per ton of waste water is more than 2.8 yuan per ton, without considering the management cost of labor and so on. The cost of 1 tons of water is definitely higher than 4 yuan, and the membrane treatment technology not only reduces its sewage discharge by 2/3, but also has obvious effect of reducing emissions and saving water. To this end, "Sheng Xin Printing and dyeing" plans to launch the two phase of membrane treatment technology. By then, the company's emissions will be greatly reduced to achieve energy saving. Emission reduction Goals.

Environmental protection and emission reduction is the driving force for upgrading

"In addition to reducing emissions and water-saving results, the pressure of environmental protection and emission reduction is also one of the driving forces for printing and dyeing enterprises to actively seek upgrading of wastewater treatment." Shaoxing Environmental Protection Bureau official said. Since last year, Shaoxing has adopted a series of major measures to tackle pollution, such as the implementation of special projects for cleaning up construction projects in printing and dyeing industry, and the "elimination system" in the printing and dyeing enterprises. This year, they also put more emphasis on the "tighten up curse" for printing and dyeing enterprises exceeding the standard of sewage. That is, the elimination of waste volume at the end of a row is changed every 3 days.

Under the severe pressure of emission reduction, Shaoxing printing and dyeing enterprises are actively seeking a way out, upgrading the technology of waste water treatment, realizing energy saving and emission reduction and alleviating the pressure of environmental protection. " Membrane treatment Technology will play a decisive role in reducing emissions in our county's printing and dyeing industry and even the whole county. " Insiders said.
