Wastewater Treatment Plant in Dongguan as much dismay the United States Academy of Sciences
Yesterday, the 2009 Innovation Forum in Dongguan 9 --- wastewater treatment technologies and resources Forum, held in Dongguan Science and Technology Museum. U.S. Academy of Engineering, the Hong Kong University of Science and Technology Professor Wong often shared governance and the audience the latest scientific and technological achievements in wastewater.
Wong is often described only the best of a city to build a sewage treatment plant
A (Reporter / European Yaqin) "34? Too much!" Yesterday, in 2009, Dongguan Innovation Forum --- 9 wastewater treatment technologies and resources Forum, held in Dongguan Science and Technology Museum. U.S. Academy of Engineering, the Hong Kong University of Science and Technology Professor Wong often shared governance and the audience the latest scientific and technological achievements in wastewater. When it comes to Dongguan will build 34 sewage treatment plants, the Wong Chang can not help but reach out three fingers, opening their eyes widely: "so much?" He suggested that a rainy day, Dongguan so many sewage treatment plants need to operate more than 400 experts personnel, reserve personnel must be ready ahead of time.
Sewage treatment plants should be better
"As long as the laying of pipe network can be put in place, only the best of a city to build a sewage treatment plant." Wong often introduced in the United States, Tennessee, there is a small city to build three sewage treatment plants, located in hilly areas because , the laying of pipeline network across the mountains to cost more. "Is equivalent to the cost of treating sewage handling charges plus the cost of network transmission, the more sewage treatment plants means that more complex pipe network, sewage collection costs are also high, therefore, theoretically less sewage treatment plants more reduce processing costs. "
Dongguan Chang Wong know when will be the construction of 34 sewage treatment plants, he can not help staring eyes, blurted out: "so much?" He said that he did not understand the situation in Dongguan, but that is expected to far exceed this figure: "I that the 34 can. "
In this regard, Dongguan City, the Environmental Protection Agency explained that the city owns more than 1000 million people, covering an area of 2,000 square kilometers, the district towns transformation of the old pipe network is too much trouble, in addition to the complex terrain of Dongguan, which eventually led to the need for a sewage treatment plant 34 of the and more.
Recommended the training of professional and technical personnel
"Sewage treatment plant instead of washing machines, there are several aspects to be a rainy day, I must remind you," Wong used to say, in the United States, a sewage treatment plant staff need to go through 10 months of induction training before they can be strict, if for each sewage water treatment plant operator of 15 staff, Dongguan need more than 400 professional staff, a great strength training.
In addition, each sewage treatment plant must be equipped with laboratories for water sample testing, calibration approach. "If each of the sewage treatment plant will require the construction of laboratories, capital investment will be very large, I suggest two or three adjacent sewage treatment plant to build the laboratory, will be combined to save some money."
Called for funding to study the Sewage
"Edge of the canal does not smell the stench." The first time the Wong Wan Chang for "走马观花" to see the water quality of the canal is still a sense of satisfaction and commended the public's environmental awareness, not throwing garbage in the canals, but also that he see a number of green floating objects: "There is no laboratory, algae do not know." Dalingshan for sewage treatment plants, he felt that the design and maintenance work are doing quite well.
"The factory in Dongguan, so waste water treatment is a very important issue." Wong often called for, the Government should set aside part of funds to maintain long-term study of wastewater treatment. "Research should be endless." He said that in the United States, each have a pre-plant at least 6 months of the simulation of wastewater treatment, and then tailor-made light of the findings of sewage treatment. "The nature of each type of waste water are different, each of the waste water discharged by factories are not the same, if not the way the program is not only the high cost, the effect is not good."
At the same time, he called on businesses to have a belief as a water pollution control will be part of the cost.
