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 Countys 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 towns 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 years 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 oftreatment 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 of enterprises 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

1.5kHz，频率稳定度优于，载波幅度1V，数字基310cmU带信号（测试信号）频率 F=1kHz。解调部分采用包络检波器实现，解调器在1VimU及无外部干扰的条件下，解调后误码率为 0。关键词2ASK；调制；解调videoconference,Secretary of the provincial Committee of Xia Baolong stressed:this year is
