综合利用率
1.The comprehensive utilization of the industrial solid wastes was 470 million tons, the comprehensive utilization rate being 52.1%.
2.We will utilize natural resources more effectively and improve the system of compensation for their use.
3.80% of the industrial solid wastes should be reused or recycling and all the hazardous wastes should be safely treated and disposed.
4.Fifth, efforts have been stepped up to save energy and reduce consumption. The capability to treat waste gas, waste water and industrial residue (the ``three wastes') has been enhanced and the comprehensive utilization rate of these materials has been increased.
5.80% of industrial solid waste should be reused by 2005 through industrial restructuring, improved the existing reuse system for coal ash and metallurgical residues and the provision of the treatment facilities for gangue and tailings. Further improvement for reuse shall be pursuit.
6.In 1995 the waste water treatment rate of the industrial enterprises above the county level all over the country reached 76.8 percent; the smoke and dust removal rate of waste gas from burning fuel, 88.2 percent; waste gas purification rate from production processes, 68.9 percent; and the comprehensive utilization rate of industrial solid waste, 43 percent. Output value attained through the comprehensive utilization of the industrial ``three wastes' came to 19 billion yuan.
7.Measures should be taken to improve the economic compensation system for paid use of the natural resources and the renewal of resources, enhance the comprehensive use rate of resources and economic profits, stop the destructive exploitation of natural resources, alleviate the controversy between the explosive population, the economic growth and the limitation of the resources.
8.According to the theme of sustainable utilization of mineral resources ,this paper points out the problems in the evaluation of mineral resources, such as the ambiguity of property rights ,ineffectiveness of overall utilization of resources, and the high discount rate and comparatively low cost.
9.Moreover, by 2004, all the husbandry industry in the area of protection zones of drinking water sources and within the Fifth Ring Road will be closed down or moved out. By 2007, all the wastewater from the allowed large scale husbandry industry will should comply with discharge limits after necessary treatment and night soil utilization rate shall reach 90%.
10.In order to retain walking tractor’s comprehensive utilization ratio, solve the question that walking tractor transport unit can’t be the fairly good traction force in the sloping fields, we adopt drived type— trailer in transport, transforming traction type into drive type, thereforce improving unit’s adhesive function, raising transport efficiency and security, at the same time we analyse the active force of the drived type— trailer transport unit.
