Opening a new mode of pollution control in Chemical Industry Park

wallpapers Industry 2020-12-09

The relocation of chemical enterprises into the park will be the mainstream trend of the development of chemical industry in the 13th five year plan and even longer period.

However, due to the increasing environmental constraints, environmental protection will become the biggest development bottleneck of chemical industry park.

Comprehensive treatment of pollution in the park is related to the survival and development of the whole chemical industry, and the solution is to put pollution control in front, that is to effectively implement source control.

This is the general consensus reached by representatives from industry organizations, research institutions, colleges and universities, chemical parks, environmental protection enterprises and other participants at the third national comprehensive pollution control conference of chemical industry parks, which was held on April 22.

Yang Ting, Secretary General of the working committee of the chemical industry park of China Petrochemical Federation, pointed out that the total industrial output value of the park has accounted for 44% of the total output value of the petroleum and chemical industry.

The output rate of land sales revenue, value-added output, profit yield and fixed asset investment rate of the park are significantly higher than those of enterprises outside the zone, reflecting the intensive advantage.

At the same time, the emission advantages of the park are particularly obvious.

The COD and SO2 emissions per unit GDP are 0.

54 kg / 10000 yuan and 0.

8 kg / 10000 yuan respectively.

"The indicators fully show that the efficiency and emissions of the park are better than the average level of the industry, and also prove that the development direction of the park is beyond doubt.

" Yang Ting said.

Yang Yuanyi, full-time vice president and Secretary General of China Chemical Industry Association, said that chemical industry parks have effectively promoted the cluster development of China's chemical industry, but with the rapid development of industrial parks, chemical pollution control has become a key and difficult problem.

Therefore, the effective control of pollution is not only related to the green development of the park, but also related to the smooth settlement and root of enterprises in the park, which is the prerequisite for the current hot chemical enterprises to move into the park.

"Obviously, under the new environmental protection law, the comprehensive treatment of Park pollution is closely related to the fate of industries and enterprises.

" He said.

Yang Yuanyi's above-mentioned conclusion was quickly confirmed in reality.

In the early morning of the opening day of the conference, news came from Hai'an County, Yancheng, Jiangsu Province.

In view of the chemical waste gas pollution problem in the local chemical industry park, the county decided to stop production and rectify all the nearly 30 chemical enterprises in the chemical park from April 20.

In order to reduce the pollution risk of the park and ensure the normal production and operation order of enterprises, many experts and scholars attending the meeting said: at present, it is a critical moment from end treatment to source control.

Shen Zhong, vice president of Jiangsu Academy of Environmental Sciences, stressed the source control mode of cleaner production.

Shen Zhong told China chemical industry news that there are five ways for enterprises to implement cleaner production: initial design, consideration of waste generation when planning products in advance.

source reduction to control the cleaning of raw and auxiliary materials and energy.

internal circulation, recycling and internal elimination.

external circulation, entering into external recycling and in-depth Industrial chain development.

end treatment and strengthening internal governance of enterprises.

As one of the top 20 domestic chemical enterprises, Taixing Economic Development Zone has accumulated rich experience in pollution source control and process control.

According to sun Qun, Secretary of the Party Working Committee of the Development Zone, Taixing Park, on the one hand, strictly controls the ecological bottom line and advocates green investment promotion.

On the other hand, we should improve the entry threshold, ensure the high level of the project, and strictly implement the expert pre evaluation and "Three Simultaneity" system.

Wang Yunli, rather than trying hard to deal with it afterwards, is better to take precautions from the beginning.

The same is true for pollution control in chemical industry parks.

Due to the concentration of production, high emission intensity and low level of clean production, the process of pollution discharge in chemical industry park is long and complex.

At the same time, restricted by the traditional concept of pollution control, the park is passive in the way of pollution control.

It often pays more attention to the unit than to the system, pays more attention to the standard than to the total amount, pays more attention to the terminal than to the source, and pays more attention to the construction than to the management.

This makes pollution control very "tired".

However, once we change our thinking, focus on source control, and change from "governance" to "prevention", the situation will be very different.

On the one hand, we can improve the level of cleaner production by selecting advanced technology, technology and equipment in advance.

on the other hand, we can reduce pollutant emissions by selecting clean raw and auxiliary materials and energy.

At the same time, it can not only save a lot of terminal treatment costs, but also increase the output benefit from improving the yield.

In fact, there are many ways to control the source, including the following ways: first, to carry out comprehensive utilization of resources, mainly by optimizing production to transform all components of raw materials into products.

second, optimizing process and equipment, simplifying process, changing intermittent operation as continuous operation, promoting large-scale plant, optimizing process conditions, and selectively changing raw material route.

The third is to organize the internal material circulation, recycle the lost materials and production wastes and then return them to the production process.

the fourth is to strengthen the scientific management, which has been proved by practice that strengthening the management can reduce 40% of the pollutant generation.

the fifth is to organize the regional clean production, carry out the industrial chain cooperation, and realize the closed material circulation as far as possible.
