The Source Of Energy Conservation And Emission Reduction Can Achieve Twice The Result With Half The Effort.

< p > 2013, Hangzhou Xiaoshan District < a href= "http://www.91se91.com/news/index_c.asp" > chemical fiber industry < /a > comprehensive energy consumption of 1 million 677 thousand tons of standard coal, 0.28% less than the previous year, energy consumption per unit of industrial added value decreased by 17.6%.

There are 63 printing and dyeing enterprises in the region. According to market demand, structural adjustment, energy saving and emission reduction, 12 backward enterprises were shut down in 2013, and the remaining 51 enterprises were brought into the government's management.

At the same time, Xiaoshan textile industry project implementation efforts are also far higher than other industries.

In the Keqiao District of Shaoxing, where the printing and dyeing enterprises were concentrated, a total of 194 stereotyping machines completed the pformation of natural gas in 2013. More than 10 stereotyping machines completed the steam pformation, and the total energy saved was about 31 thousand tons of standard coal.

Guangdong's textile industry water consumption control in 2013 was initially within 6 billion tons, and the average water reuse rate was about 20%.

< p > although enterprises act positively to promote energy saving and emission reduction, there are still many difficulties in actual operation.

At present, the difficult problems commonly reflected by enterprises are mainly concentrated in three aspects.

< /p >

< p > one is the heavier task of saving energy.

For example, Zhejiang requires the Xiaoshan and Keqiao districts to achieve the goal of reducing energy consumption by 18% and 21.5% respectively in 2015, and reducing the total energy consumption by 20% and 10%. However, there is a dilemma between the implementation of the "double control". When the economic situation is good, the total energy consumption is difficult to control. When the situation is not good, the target of energy consumption per unit is difficult to achieve.

Since 11th Five-Year, textile enterprises have been actively carrying out various energy saving technological pformation projects, < a href= "http://www.91se91.com/news/index_c.asp" > energy-saving space < /a > smaller and smaller. Continuous investment in energy saving and consumption reduction has also led to huge cost pressures for enterprises.

< /p >

< p > two is the difficulty of indirect discharge of wastewater.

Due to the disproportionate effect of capital investment and treatment, and the lack of technical strength, and the existing plant area is difficult to support the upgrading project, most printing and dyeing enterprises need to meet the requirements of wastewater discharge standards only by their own strength.

But the implementation of unified preprocessing is also faced with the new emission standards for enterprises indirect emissions COD requirements below 200 of the provisions.

< /p >

< p > three is the related demand that needs to be reflected urgently.

The current demands of enterprises mainly include centralized pretreatment projects, which are slow progress by land targets. Enterprises wishing to meet the direct discharge requirements of waste water do not want to directly discharge through nanofiltration. Coal to gas is conducive to reducing exhaust emissions, but the cost is high, and the source of gas is also unstable.

< /p >

< p > aiming at these problems, < a href= "http://www.91se91.com/news/index_c.asp" > China Textile Industry joint < /a > people pointed out that in energy saving and consumption reduction, one is to popularize energy management and control informatization, and to display all kinds of energy consumption data in the production process in time, which is convenient for enterprises to adjust and facilitate government monitoring. The two is to adjust measures to local conditions and encourage various forms of energy saving, such as coal conversion to steam, solar energy and biomass fuels.

Wastewater treatment can be centralized and unified.

For example, the Keqiao government led aggregation project has the advantage of using government financial funds to invest in the operation of sewage treatment plants. The waste water and sludge in the park can be centrally disposed and disposed uniformly so that the law enforcement departments can supervise and supervise them. The enterprises pay sewage charges to the sewage treatment plants according to the concentration of COD in the waste water, which lightens the burden of pollution control and is in line with the interests of the enterprises.

At the same time, strengthen control at the source.

Experts believe that the reduction of pollution sources is the biggest reduction of emissions. In technology and technology, finding new ways and technologies is much more economical and effective than reducing pollution.

In addition, the "cover" project, which is appreciated by the experts, has not only ensured the normal operation of the water treatment process, but also solved the influence of "peculiar smell" on the surrounding environment, as well as the recovery and utilization of heat energy. It is known as a comprehensive energy conservation and emission reduction system project.

< /p >

< p > in terms of waste gas treatment, the state strictly controls the discharge of four pollutants, such as inhalable particulates, sulfur dioxide, nitrogen oxides and volatile organic compounds (VOC).

There are preventive measures for the first three kinds of pollutants, such as bag type dedusting, electrostatic precipitator, desulphurization and denitration.

The VOC produced by chemical fiber and printing and dyeing industry has no monitoring methods and means at present.
