Second, landfill disposal of garbage. Due to many factors, such as capital, processing capacity, technical requirements, waste composition, etc., Taiyuan City mainly adopts sanitary landfill method to treat domestic waste at present. Most landfills choose deep ditches, with no springs around and deep groundwater level. At the same time, it is equipped with facilities such as matrix, exhaust and leachate collection, and buried in layers, filled with a layer of garbage, covered with a layer of loess, and so on. The garbage removed from various garbage stations and transfer stations in the city is finally sent to landfill sites for landfill treatment. At present, there are three domestic waste sanitary landfills in Taiyuan, namely Shanzhuangtou, Shele and Xingou, among which Shanzhuangtou and Shele have been closed. Dongshan Xingou Landfill absorbs 400 to 500 cars of garbage every day, with a total amount of more than 2,000 tons, and now its capacity is close to saturation.
Third, special garbage incineration. For all kinds of medical wastes, Taiyuan established a special waste incineration plant with a daily processing capacity of 100 tons in 1995. Up to now, 96 medical units with more than 50 beds have signed collection and incineration agreements with special garbage incineration teams, accounting for 75% of the total, and about 45 tons of medical waste are recycled and incinerated every day. The city produces about 6.5438+0.5 million tons of medical waste every year, and incinerates about 7,000 tons. Failure to achieve complete incineration treatment is not a lack of capacity, but a management problem. There are still more than 25% medical units (including suburban hospitals) and 1000 individual clinics and foreign-related hotels in the city that are not under centralized management. Special garbage refers to toxic and bacterial garbage, which is mainly produced in hospitals, clinics, foreign-related hotels and other places. Special garbage must be stored in a sealed way, collected and transported in a unified way, burned centrally and treated harmlessly. However, due to the shortage of funds, two of the four special garbage trucks of the incineration team of Taiyuan Environmental Sanitation Bureau have reached the age of scrapping. Incinerators should be overhauled every three years. Due to the operation of a single furnace, it has been running continuously for 4 years without overhaul. Once the boiler is stopped due to fault, the consequences will be very serious. The Measures for the Administration of City Appearance and Environmental Sanitation in Taiyuan, which was adopted in 2000, clearly stipulates that toxic and hazardous wastes generated by medical units and other units should be disposed of in accordance with relevant state regulations, or entrusted to professional units for unified collection and disposal. It is forbidden to burn, bury, transport or mix with other garbage for dumping. Those who burn, bury, transport or dump toxic and hazardous wastes without authorization according to regulations shall be fined 1000 yuan or more 1000 yuan or less. At present, it is still necessary to strengthen management, standardize the rights and responsibilities of special waste producers and processors in the form of local laws and regulations, and completely block the secondary pollution of medical waste and endanger society.
