| By analyzing the Xinjiang Uygur Autonomous Region to produce five-hazardous waste disposal,the use of storage conditions,a comprehensive analysis of hazardous waste generation regions,industries, types of hazardous waste, key enterprises,hazardous waste disposal capacity utilization, etc., to find the Xinjiang Autonomous Region of hazardous waste pollution prevention and control problems, simultaneous contrast gap with foreign and domestic advanced provinces,study and formulate a pollution control strategy for Xinjiang Uygur Autonomous Region. Forming conclusions are as follows:Hazardous waste generation during the Twelve five declined Xinjiang Uygur Autonomous Region,the overall disposal rate upward trend during the second five total industrial hazardous waste involving a total of up to 49 categories of hazardous wastes to reach all 858 companies,hazardous waste generation in species reach 29 classes,2010- The2014 amount of hazardous waste generated was 664,800 tons,688,000 tons,340,600 tons,301,700 tons,471,800 tons,the overall downward trend.Xinjiang Uygur Autonomous Region of hazardous waste are mainly concentrated in the high-level of industrial development in our region Karamay,Urumqi,Bazhou,Aksu Prefecture,Ili,Turpan and other six states in the region,the region produces a small amount to the state for the g state,Bozhou Altay,a lower level of industrialization of the region's area and Hetian no industrial sources of hazardous waste generated.A large amount of hazardous waste generated in the industry followed by oil and natural gas industry,petroleum processing,coking and nuclear fuel processing industry,non-ferrous metal smelting and rolling processing industry,ferrous metal smelting and rolling processing industry,chemical materials and chemical products manufacturing 5 industry,generating 90%of all of the above accounts. Most popular types of hazardous waste generated mainly HW35 waste alkali(petrochemicals),waste mineral oil(oil,petrochemicals),HW34 waste acid(metal smelting),steam distillation residue HW11,HW42(chemical industry),etc.,and hazardous waste distribution industry remained the same.Currently Xinjiang Uygur total area of hazardous waste management units can take advantage of 46 kinds of hazardous waste disposal Total disposal capacity of 790,000 tons use.HW08 class which total more than 600,000 tons,is the use of Xinjiang hazardous waste disposal capacity of the largest species,followed by a total of 62,500 tons class HW42, HW35 category total 20,000 tons,HW34 category total 14,000 tons,HW06 category total 12,000 tons,HW11 category total 10,000 tons.Through analysis,the Xinjiang Autonomous Region there are unrealistically high utilization of hazardous waste disposal,hazardous waste disposal capacity kind of uneven distribution of individual species exhibit excess and shortage of some species coexist,comprehensive hazardous waste disposal facilities can not meet the current needs,inadequate supervision capacity of hazardous waste,grasp the real situation of hazardous waste is not comprehensive enough and accurate,hazardous waste management capacity does not match with the actual work requirements,environmental management of hazardous waste at the edge of the situation did not improve environmental protection work,the implementation of existing laws and regulations are not in place,lack of local realistic supporting laws and regulations and other issues.By correlation analysis,GDP and the amount of hazardous waste per unit of GDP was negatively correlated,that is,as the national economy, developments in the economy and the level of intensity of hazardous waste generated have a great relationship GDP growth,hazardous waste generated per unit of GDP strength is lowered.Through research,through the strengthening of hazardous waste pollution source control,strict access,strengthen the audit examination and approval,to increase the elimination of backward production capacity,optimize the industrial layout,speed up the construction of hazardous waste disposal facilities,to strengthen the environmental management of hazardous waste,improve the basic data statistics,strengthen supervision of solid waste environment,environmental regulatory capacity building,improve institutional mechanisms,laws and regulations and other countermeasures to make the Xinjiang Autonomous Region of hazardous waste pollution prevention and control levels improved. |
