Iron Carbon Micro Electrolysis Packing For Printing And Dyeing Wastewater Treatment

Printing and dyeing wastewater is characterized by large amount of water, deep color, strong alkalinity and large variation of water quality.

High content.

At present, printing and dyeing wastewater is generally treated by biochemical method, coagulation sedimentation method, coagulation gas floatation method and activated carbon adsorption method.

These methods have high investment cost and difficult management, and the decolorization effect and removal rate are not ideal.

In recent years, a lot of research results and technical patents on printing and dyeing wastewater treatment by electro chemical method have been reported, and applied to wastewater treatment projects of printing and dyeing enterprises of all sizes, and good results have been achieved.

Experimental results show that the micro electrolysis method has a significant removal effect on the polluted wastewater. When the influent pH is about 1 and the contact time is 0.5h, the removal rate of COD is about 60%, and the chroma removal rate is more than 94%. The micro electrolysis method mainly removes COD and chromaticity by oxidation-reduction and iron flocculation.

Using micro electrolysis to treat dye wastewater, the removal rate of CODcr is about 67%, and the decolorization rate is almost 100%.

The results showed that acidic wastewater was beneficial to remove CODcr and decolorization, and the acidic wastewater with pH value of 4 was suitable.

Time is beneficial to improve the treatment effect, but will increase investment and operation cost. The reaction time should be controlled at 50min. The amount of lime milk will affect the removal of CODcr when the amount of lime milk is too much or too little. When the pH value is adjusted to 9, it is more suitable; the mass ratio of iron filings to coke is the best when the micropoint reactor is 1: 1.

According to the data released by the General Administration of customs, China's exports decreased by 6.6% in January, and imports dropped by 14.4%.

As a big exporter of China's textile industry, the textile industry has been facing the pressure of structural adjustment in recent years.

China will carry out the supply side reform during the "13th Five-Year" period.

For the textile industry, only through the development and application of new materials, new technology, new technology and new equipment through the talent innovation and technological innovation, can we promote the development of product variety, quality and enterprise brand, so as to meet the new demand and get new impetus for development (310328, fund).

Yang Weidong, the representative of the Municipal People's Congress and the general manager of the Group Limited, said.

As a member of Qingdao's 10 billion enterprise camps, the company is taking the opportunity to solve the plight of the textile industry through technological innovation, talent innovation and mode innovation.

Among them, at the strategic level, that is, to seize the new strategic opportunities of "one belt and one road", and to make use of the opportunities of infrastructure improvement to carry out the layout of global production, global brand and global market, will build fabric factories in Southeast Asia, plus the garment factories which have been put into use before, will realize the whole industry chain operation, reduce operation costs and policy risks.

At the same time, it is making use of the strategic opportunity of "made in China 2025" and "Internet +" to push forward the pformation of production mode and carry out the intelligent pformation composed of intelligent production, intelligent management and intelligent clothing.

Yang Weidong introduced, in 2015, signed a letter of intent to cooperate with Dongli, Japan, and so on. The smart clothing was embedded in the clothing layer to detect the heartbeat, body temperature and other data of the body. It was pmitted to the computer, mobile device terminals and cloud system through external sensors to achieve real-time monitoring of human health.

Smart clothing is expected to enter the market in 2017 and usher in epoch-making changes in the garment industry.

In the field of electric business, that is to say, it has deep exploration and good performance. Under the banner, China and the company accelerate the sales of "Qin Ou" children's wear network, and the "double 12" sale of children's wear products on the same day more than 20 thousand pieces.

In addition, the completion and commissioning of the Dongli medical technology project marks a solid step towards the development of the life science industry, and the construction of the Silicon Valley marine biological materials research and development platform and other projects will go smoothly, which will provide strong support for enhancing the capability of independent innovation and improving the design and research level.

That is to say, we should take the building of our own brand as a global strategic task, lay a new strategic height in opening up the domestic market, strive to improve the level of creativity and design, continue to develop marketable new products, actively develop new marketing models such as e-commerce, accelerate the pformation of comprehensive resources advantages to domestic sales advantages, and create a new situation of "promoting both internal and external markets and advancing simultaneously online and offline."
