videoconference, Secretary of the provincial Committee of Xia Baolong stressed: this year is the "five water treatment" "357" timetables "for three years to resolve outstanding issues, obviously worked," victory of the year. The County's departments at all levels must firmly establish the "guanghui is gold and silver" green development concept, convinced that Castle is not relaxed, always maintaining strategic ability and strong determination to improve the environment, consistently playing well "five water treatment of" winning the war, ever-higher levels of comprehensive well-off society was built. (A) lay the sewage uphill battle. This year we will "river water quality improved at the county level, up to five" this basic objective grasp of pollution control that focus, with the focus on three things: a good job, "clear rivers" reaching the County created. Organization "look back" special inspection, the County garbage River, black and odorous River is "Dragnet" investigation, timely rectification of problems found in place firmly to prevent river pollution rebound. In accordance with the "one-stop strategy", improving the inferior five water quality monitoring stations work this year to ensure the Elimination of 1 provincial control, five water quality section 3 municipalities controlled deterioration, ensure the creation this year of "clear rivers" standards. Second, pay special attention to pollution-cutting construction of nanotubes. Intercepting nanotubes are the basis of pollution of water source engineering, engineering, matter of success or failure of water management. Urban sewage treatment, to improve "effluent from sewage treatment rate, running accuracy, compliance" requirement, speed up the town's support network construction, is focusing on nanotubes home "last meters" question. Domestic sewage treatment in rural areas, this year is the final year of the three-year action, determination to fight and the momentum around, ending the battle on which fully to ensure the realization of all County 648 formed village coverage. Also, be sure to attach importance to focus on rural domestic wastewater treatment facility operation and management, ensure that wastewater treatment facility up and running, role play, avoid the "Sun" problem. Third, pay special attention to the River Lake pond desilting operation. Provinces now have focused on pollution control of water go to "dig up mud", as the deepening water of this year's "plays". Next, to jump-start an investigation line touches work, implementation plan according to the priorities and the programme of work, in accordance with the "one river one policy" requires detailed cleaning, dredging plan, planning ahead of time cleaning out mud "way out", according to local conditions to do sludge, promote scientific resource utilization of silt and mud. (B) the heavy regulation of heavily polluting industries. Pollution of water must grab the source, wastewater is primarily the source of backward production capacity, increase the intensity of第一节工艺管线制安

treatment of heavily polluting industries. According to municipal, and municipal government deployment of seven big heavy pollution industry regulation "three years action plans", requirements to December 2016 end of Qian, all included shut stopped eliminated of enterprise all shut stopped eliminated in place; June 30, 2017 Qian, all included place regulation upgrade and agglomeration restructuring of enterprise by unified standard regulation in place, late not standard of enterprise are implementation discontinued; June 30, 2018 Qian, all intends Park production of enterprise relocation Park in place, late not Park of are discontinued. In the process of renovation, will focus on four aspects: to firmly close the high energy consumption and heavy pollution, hopeless enterprise governance and production lines, eliminated a number of yearly emission intensity, low value-added products of backward production capacity. Second, we must strictly enforce the space, total project "Trinity" environment access system, promoting industry access and environmental conditions of access ofenterprises to the Park, industrial park, in principle, no longer the class on the new project. Thirdly, promoting replacement and reconstruction of heavily polluting industries, mergers and reorganizations, guide enterprises to energy conservation, recycling and low-carbon and clean production, and improve the level of green development. Four to establish a long-term supervision mechanism, increase the intensity of special inspections, investigate and punish the rectification is not in place, normal business of running anti-pollution installations do not. (Iii) linkage to promote flood control water, drainage, water supply, improving water saving. Speed up cross ang support river dike reinforcement, and along Pu seawall except insurance reinforcement, and Lake Qian sluice, and BA Cao sluice, and cloud cover reservoir, focus flood control drainage engineering construction, vigorously implementation "strong library" "solid di" "spread row" engineering, increased geological disaster hidden points governance efforts, solid advance small basin torrent disaster governance, efforts from essentially solution basin sex, and regional flood control drainage capacity insufficient of problem. Vigorously implement the piers, algae and other water sources protection and, promoting rural drinking water safety projects, setting up water pricing reform and environmental protection mechanism, guiding water depth. Further soil pollution and repair, strengthen agricultural non-point source pollution prevention, mountain, water, forests, fields, lakes, various elements mutual long. Four, manage to tighten control, to play "three to split" battle. Xia Baolong, Secretary of provincial party Committee stressed that while the "three to split" operation time is over three years, but "three to split" must continue to catch on, and resolve a split cannot be changed.
