Zhou Shengxian, director of the State Environmental Protection Administration, pointed out at the meeting of the National Bureau of Environmental Protection that in 2008 Chinaâ€™s environmental protection department will increase its pollution reduction efforts and take more effective measures to control the emissions of sulfur dioxide and chemical oxygen demand.
Zhou Shengxian said that it is necessary to conscientiously implement the â€œComprehensive Work Plan for Energy Saving and Emission Reductionâ€ and focus on promoting structural emission reduction, engineering emission reduction, and management emission reduction to ensure that the emissions of sulfur dioxide and chemical oxygen demand in 2008 decreased by 6% and 5 respectively compared with 2005. %.
It is understood that in terms of structural emissions reduction, in 2008 China required the shutting down of 13 million kilowatts of small thermal power, eliminating 6 million tons of steelmaking, 50 million tons of cement, and 14 million tons of ironmaking backward production capacity. Environmental protection agencies at all levels must strictly implement the industry. Policy, do a good job in shutting down the elimination work.
In the aspect of project emission reduction, this year will increase the daily treatment capacity of urban sewage by 12 million tons. In 2008 and 2009, 36 large and medium-sized cities will realize the full collection and treatment of sewage; existing coal-fired power plants will complete more than 30 million kilowatts of units Desulfurization facilities installation project, and completed 10 flue gas desulphurization projects of 1,000 square meters of steel sintering machine.
In terms of management of emission reduction, environmental supervision should be strengthened. Enterprises that do not meet environmental protection requirements must be restricted in production limits, stop production, rectify and shut down, and heavily pollute industries such as chemicals and paper, and other pollutant emission standards exceeding and exceeding total discharge. Indicators, production or use of toxic and hazardous substances, the implementation of mandatory clean production audit.
The â€œEleventh Five-Year Planâ€ outline clearly states that the total discharge of major pollutants in China during the â€œEleventh Five-Year Planâ€ period should be reduced by 10%, with an average annual reduction of 2%. However, the data show that the total discharge of major pollutants in China is still increasing in 2006. Among them, chemical oxygen demand increases by 1%, and sulfur dioxide increases by 1.5%, although they have fallen by 4.6 and 11.6% respectively over the previous year. , but did not complete the target of 2% reduction in the year. In the first three quarters of 2007, the total emissions of the two major pollutants nationwide fell for the first time. Among them, sulfur dioxide emissions decreased by 1.81% year-on-year, and chemical oxygen demand decreased by 0.28% year-on-year.

The pillar hydrant, also sometimes referred to as the dry barrel hydrant, is one of the most visible signs of fire protection measures that can be employed by firefighters. They are placed in the streets for emergency purposes, and are utilized mostly if there is a fire in the immediate vicinity. The pillar hydrant is connected to the area`s water supply, which means that at any given time, the water supply can be utilized through the dry barrel hydrant. If a fire occurs in a place with a hydrant close by, firefighters can easily connect their hose lines to the dry barrel hydrant and use the water in the extinguishing process
