Xinhua News Agency, Shijiazhuang, August 28 (Reporter Wang Min) The lake is clear, surrounded by flowers and trees, fish and water, and birds in the birds ... This is an ecological scenery in the coal port area of Huanghua Port, Hebei. Huanghua Port Coal Port, located at the top of the Bohai Bay Dome, through the collection of storage cockpit water, purifying coal and sewage, and undertaking "Sky Water", producing over 90 % of freshwater self -sufficiency, and the energy port of "bitter sea along the border" achieves cost reduction and "green "".

As the largest exit of Western Coal Eastern and Bei Coal South Transport in China, over 200 million tons of coal is laid off in Huanghua Port each year. Coal transportation requires a large amount of fresh water to clean dust and suppress, while the saline resources of the Bohai Bay salt -alkali in Huanghua Port are lacking. The coal port area of Huanghua Port transformed the original garbage dump and free wasteland into "two lakes and three wetlands" for filtering, storage cockpit water, purifying coal and sewage, and rainwater. A complete water circulation system.

Most of the cargo ships in the south, especially the Yangtze River Basin, mostly carry a large amount of fresh water for pressing the cockpit. After the ship arrives in Hong Kong, it needs to be emptied after emptying the cockpit water. In the past, these freshwater discharged into the sea not only waste water resources, but also caused some pollution to the marine environment.

Similarly, every year the rainy season, especially after heavy rain and rain, a large amount of rainwater is hoarded in the port area. If it is not treated in time, it will cause water or rainwater to enter the sea in the port area. Huanghua Port collects all these water, which not only enriches the freshwater resources of the port area, but also solves the problem of pollution of seawater.

The manager of the operating party of Huanghua Port Coal Port Area and the Manager of the Production Guarantee Center of Guineng Huanghua Port Co., Ltd. introduced that after the transformation of some cargo wheels, the pipeline of water in the cockpit was entered into Tamsui Lake. 1.5 million cubic meters, becoming the main source of the "Lotus Garden" and "He Garden" lakes. In the rainy season, the runoff formed on the surface can be discharged into the wetland through the pump station, and 400,000 cubic meters of rain can be undertaken each year.

Earlier, coal and sewage formed by washing coal belts, sprinkled water, and rainwater was washed. In recent years, Huanghua Port's coal port has introduced coal and sewage into three sewage treatment plants, which can deal with 2.05 million cubic meters a year, and the remaining three wetlands are excluded. Last year, the mud settled in the wetland was made of 1,400 tons of coal cake, which created more than 9 million yuan.

In order to make good use of the "three water", Huanghua Port Coal Port area has developed a set of green ecological control platform systems. The operation and production of water systems through monitoring equipment throughout the port area, and the water source is reasonably deployed according to different water needs. Precisely used for production and realizing scientific storage and application of water resources. "The‘ two lakes and three wetlands ’in the port area connects each other, which can achieve step -by -step precipitation, balanced water, recycling water, and the use of resource utilization to maximize '." Huai Quan said.

According to reports, more than 3.7 million cubic meters of freshwater in the coal port area of Huanghua Port, through the collection of storage cockpit water, purifying coal and sewage, and undertaking "sky water". The cost of about 19 million yuan in the annual festival is more than 19 million yuan. The "two lakes and three wetlands" in the port area created a green ecological landscape. This has become the first domestic AAA -level coal port industrial tourist attraction, and has won the honor of the "China Environment Excellent Award" and "5 -star green port".
