“Carrier microorganism technology is to domesticate the best microorganisms in active sewage, and after screening, make these microbial flora’ sleep’ in a multi-enzyme carrier, and through continuous reproduction, the effect of decomposing river pollutants such as total nitrogen and total phosphorus can be achieved. Using this method, the effect of one-time delivery can reach more than 10 years.” On April 27th, Han Yalin, manager of China area of biocleaner Company of the United States, said with a smile that carrier microorganism technology can be said to be a “fool” sewage treatment method at the report meeting on “declaring war on inferior V technology in action”.
On the day of the event, more than 200 experts in the field of environmental protection from home and abroad shared the new water control technology for the staff of water control offices of cities and counties (cities, districts) in the province, management and scientific and technological workers of environmental protection and water conservancy departments, relevant personnel of workstations of various environmental protection platforms, and representatives of some environmental protection enterprises in the province who are committed to the research and promotion of water treatment technology.
This meeting is the first special large-scale activity in the “2017 Action Plan for Eliminating Inferior Class V Science and Technology” issued by the Provincial Environmental Protection Department, the Provincial Science and Technology Department and the Provincial Water Control Office. It aims to fully implement the decision-making arrangements of the provincial party Committee and the provincial government on “eliminating inferior Class V water” and further promote the prevention and control of water pollution in our province. According to the actual needs of the grassroots, relying on the chief technical advisory group for water control, the provincial science and technology innovation service platform, scientific research institutes at all levels, and domestic and foreign,
Wang Yimiao, deputy director of the Environmental Protection Department of Zhejiang Province, said at the meeting that water control drives transformation and upgrading, and it is necessary to fully understand and attach great importance to the elimination of inferior V water, and long-term water control should be based on a scientific and realistic attitude.
According to statistics, all the inferior V-shaped sections above county level in our province include 6 provincial inferior V-shaped sections, 27 municipal inferior V-shaped sections and 25 county inferior V-shaped sections. Xu Luzhong, deputy director of the Water Control Office of Zhejiang Province and deputy inspector of the Provincial Environmental Protection Department, believes that at present, the main causes of the inferior V-class water in our province are that the sewage interception and management are not in place, the industrial renovation is not in place, the water ecological restoration is not in place, and the implementation of the river length system is not in place. It is clearly proposed that the inferior V-class water should be destroyed in a whole process, a whole system and an all-round way around the words “interception, clearing, treatment and repair”.
Xu Xiangyang, vice president of the School of Environmental Protection, Zhejiang University, and other 33 experts in the field of environmental protection were appointed as the chief technical consultants of “Destroying Bad Class V Water” in Zhejiang Province in February this year. They are responsible for consulting the current situation of 33 water bodies in Zhejiang Province, taking care of their pulse, guiding and serving the work of “Destroying Bad Class V Water” in various places, and cooperating with river chiefs at all levels in various places to be good staff of scientific and technological water control.
At today’s meeting, Xu Xiangyang said that the defects of pipe network collection, urban and rural non-point source pollution, tail water discharge load, endogenous pollution of sediment and ecological damage of water body are the main problems in the current water environment. Do a good job of pollution.Water treatment, external siltation and emission reduction, and endogenous dredging are prerequisites, hydrodynamic improvement and water purification are phased means, and ecological reconstruction and self-purification are long-term protection.
The reporter learned at the meeting that before the end of the year, our province will completely eliminate the inferior V water quality sections in the province, reduce the inferior V water quality sections in the city, and complete the national “Water Ten Articles” and “Zhejiang Water Pollution Prevention and Control Target Responsibility Book” three years ahead of schedule. The target task of eliminating inferior V water quality sections.
This meeting is another special action of “science and technology to suppress inferiority” in our province, and then many “peer-to-peer” technical services and environmental protection science popularization activities will be carried out throughout the province to provide scientific and standardized pollution control services for the grassroots and create a good atmosphere for the whole people to control water.
