Liaoning is a famous old industrial base in China, especially the industrial base of heavy chemical and raw materials, and has a long history of industrial production, which is known as the "eldest son of Chinese industry".

For a long time, liaoning has been making outstanding contributions to China's economic development while remaining serious pollution problems.

Among them, the repair of industrial pollution site is one of the key environmental problems that need to be solved urgently.

In recent years, liaoning province has carried out a lot of work for industrial site pollution repair, which has achieved remarkable results.

Case 1: iron west "scratches"

Liaoning has been the earliest and most successful in the treatment and rehabilitation of contaminated sites.

If the industrial pollution site in liaoning began in shenyang, then shenyang began in the west end.

The west end of China's "ruhr" is the old industrial base built in the "one and five" and "two and five" periods, and later became the famous heavily polluted area.

In 2003, shenyang seize the country an opportunity to implement the strategy of rejuvenating northeast old industrial base, big operation to shenyang development zone and the old I rust merged to form a new scenes, namely the use of land differential moved to old I industries development zone;

The new service industry will be embedded in the old railway west, making it a focus of modern service industry.

As early as in August 2000, is located in shenyang I known as the "cradle of non-ferrous metals industry" in China of shenyang smelting plant, due to the serious pollution problem cannot be solved is declared bankrupt, is our country so far because of pollution and the biggest state-owned companies were closed.

At the same time, the pollution site restoration project was also launched. By 2006, 120 million yuan had been invested to complete the management and repair work of 300,000 square meters of contaminated site.

This is not only the first restoration project in China to carry out the closure of enterprises, but also the most widespread site restoration in the country at that time.

Subsequently, the western district started the management of shenyang battery factory pollution site;

Later, the pollution site of shenyang heavy machinery factory was implemented.

At that time, all adopted "scraper cure poison" way of governance, the contaminated land poison soil dug up, to a qualified disposal unit responsible for pickup and safe disposal, again with a new backfill soil.

This experience is fully affirmed by the ministry of environmental protection, and becomes a "template" for China to solve the problems of the relocation of polluting enterprises and the post-bankruptcy environmental problems.

And, also on has a history of decades of sewage irrigation in liaoning province "Shen Fu irrigation system" of pollution on the land, effectively solves the problems of petroleum contaminated soil organic matter, for the governance of rural land, to explore a new road.

In addition, shenyang has turned the cadmium pollution area into an economic development zone, which was also a successful example of the reuse of contaminated sites.

Case two: shen hua, dongyao capital management

The global environment facility "contaminated site management project in China" is in the Chinese government to perform "the Stockholm convention on persistent organic pollutants (pops) framework, by the environmental protection department, ministry of finance and the development of the world bank cooperation international grants program.

So far, liaoning and chongqing municipality have been included in the project demonstration provinces.

Among them, liaoning province selected "Shenyang Chemical Industry Co., Ltd." and "relocation site of northeast pharmaceutical group" as the demonstration project of the project.

Last year, the environmental protection department's external cooperation center signed a project execution agreement with liaoning province in shenyang.

Shenhua and dongyao are the important chemical raw materials and pharmaceutical production enterprises in liaoning, and the demonstration projects of two plots are located in the old urban area of the western district.

According to the relevant personnel of the project office of the pollution site management project in liaoning province, the first choice of the two plots, the shenhua and dongyao, is because of the recent relocation and the urgent need for development.

Two products, such as DDT in the 1950s and 1960s, were persistent organic pollutants.

This is a kind of long-term persistent, bioaccumulation, half a volatile and highly toxic, and through a variety of environmental media (air, water, biological, etc.) for migration, long distance to has serious harm to human health and the environment of natural or synthetic organic pollutants.

At present, the environmental pollution situation of 138 plots has been investigated in the environmental protection office of liaoning province, but the number and location of contaminated plots have not been released.

Although shenyang has used incineration and remediation methods for heavy metal pollution sites in the past, the pollutants in shenhua and dongyao are more complicated.

Although the deadline for the completion of the project is from 2015 to 2021, the governance time can be controlled according to the company's relocation schedule and the specific needs of the land development.

Liaoning have confidence in the complete "China's pollution site management project" agreement "provisions action", will also combined the actual liaoning completes the "voluntary", really will Shen Hua and DongYao two engineering make it worthy of the name, benchmarking embody its demonstration significance.

Liaoning for ten years

Liaoning, as one of the pilot provinces in the national soil survey, was the first to carry out soil survey within the province.

Companies over the years, as many pollution transfer to the rural, rural large amounts of chemical fertilizers and pesticides, not only destroyed the local farmers' living environment, more let people worry about the safety of agricultural products.

Therefore, it is imperative to repair the polluted land in the countryside.

In accordance with the requirements of the state, liaoning has conducted a review of the industrial pollution sites that have been shut down in the province and made use of it, and determined the scope and objectives of the later industrial site pollution control.

Liaoning to prevent industrial enterprises in the process of shutting down move to steal, steal the bottom and not regulate the behavior of demolition, developed the industrial enterprises in liaoning province closure, relocation and site area to work in the process of development and utilization of pollution prevention plan.

The government of liaoning province has issued a plan for the prevention and control of soil pollution in liaoning province, and has listed soil and atmosphere, water, rural areas and qingshan as the top five environmental pollution control battles in the province.

Liaoning will mainly focus on petroleum, chemical industry, smelting heavy industry city, focus on industrial site, historical sewage irrigation and soil pollution, oil fields, mines strengthen the prevention and cure of soil pollution, and gradually improve soil environment quality.
