Kunming's introduction of a market mechanism forced the improvement of watershed management——
Dianchi Lake sees the water again and clears the shore green (the three major battles are in action everywhere)
"The city's ecological compensation fee for water treatment is only 8 million yuan a month, but I did not expect that the 2 km Wangjiadui canal will pay 2 million yuan a month!" This ecological compensation fee surprised Hu Hongbo, who has been treating water for 5 years...
That was August 2017. As the specific manager of the ecological compensation fund of the Xishan District Water Affairs Bureau in Kunming City, Yunnan Province, Hu Hongbo was busy advancing the management of the large river basins such as Daguan River and Xinyunliang River. "It may not take so much to buy clear water How much money do you say?"
Dianchi Lake was once one of the most polluted lakes in my country. In order to fundamentally improve the ecological environment of Dianchi Lake, in July 2017, Kunming City implemented an ecological compensation mechanism in the Dianchi Lake Basin, and quantified the assessment of river channel management-the excess values of the chemical oxygen demand, ammonia nitrogen and total phosphorus content were multiplied by The amount of river water is the total amount of river pollution load; multiplied by the unit price of pollution load is the ecological compensation to be paid. The Wangjiadui Canal is one of the Dianchi Lake channels into the lake. It has less water in the dry season, but it has a higher value than the standard. Although the pollution concentration in the rainy season is low, the water volume has increased suddenly, and the ecological compensation has not been paid. "It's all about spending money, it's better to take the initiative to control instead of passive payment." It has become the consensus of the party and government cadres in Xishan to treat the sewage standard as a "clean water" to make up the river. "We have listed the bills to the financial department: how much they paid for ecological compensation and how much they invested in governance, they can see at a glance, and the strength and progress of fiscal capital guarantees have also been greatly improved." Hu Hongbo said.
The Xishan District Water Affairs Bureau introduced a market mechanism to look at water quality without looking at facilities. "To put it simply, no matter what kind of water treatment measures are used, we will eventually pay according to the water quality that meets the standard." Hu Hongbo said that if the water quality is not up to the standard, the bill will not be paid, and the government does not have to worry about wasting money. At the end of 2018, two decentralized sewage treatment projects in the Wangjiadui Canal's last and middle sections were openly tendered, and the water quality after treatment reached Class IV standards. Li Lingling, general manager of one of the winning environmental protection technology companies, introduced: The company uses new technology to dephosphorize and denitrify. After the original domestic sewage is purified, it is led to the upstream replenishment channel without reducing the amount of water entering the river and increasing the flow of water.
One year after the market bidding project was launched, the water quality of the Wangjiadui Canal has improved significantly. Before the implementation of the water control project, Wangjiadui had paid a total of 5.11 million yuan in ecological compensation in 2018. After the project was implemented, the government spent only 2.2 million yuan on the purchase of standard water.
In 2019, the ecological compensation paid by Xishan District to Kunming City totaled 45.32 million yuan, while in 2018 the figure was 101 million yuan. Monitoring data shows that the water quality of the entire lake in Dianchi Lake will maintain category Ⅳ in 2019 and will continue to stabilize and improve.
Hu Hongbo now puts more emphasis on ecological restoration: demolishing breakwaters, constructing ecological wetlands, and restoring the self-purification of river channels..."We must work hard on comprehensive governance, system governance, and source governance, and return the people to a clean water. The shore-green Dianchi Lake."
