introduction
With the continuous acceleration of urbanization, the problem of urban domestic waste disposal is becoming increasingly prominent. As an efficient and energy-saving treatment method, waste incineration is widely used in the treatment of urban domestic waste. However, the quality of waste directly affects the operating efficiency and environmental performance of incinerators. This paper will discuss how to ensure the waste quality of urban solid waste incinerators from the aspects of pretreatment, garbage collection management, technical testing and quality monitoring, quality traceability management, feed management, sorting and recycling, equipment maintenance, and supervision.
1. Pretreatment
Pre-treatment is the first step in ensuring the quality of your waste. Pretreatment includes crushing, screening, dehumidification and other processes, with the purpose of crushing large pieces of materials in the garbage into small pieces suitable for incineration, removing non-combustible substances and moisture, so as to improve incineration efficiency.
2. Garbage collection management
Waste collection management is an important part of ensuring the quality of waste. A complete garbage collection system should be established, including garbage drop-off points, collection vehicles, transportation routes, etc., to ensure that garbage is collected to the incinerator in a timely and effective manner. At the same time, the garbage collection process is strictly monitored to prevent garbage from being illegally dumped or mixed with hazardous substances.
3. Technical testing and quality monitoring
Technical testing and quality monitoring are important means to ensure the quality of waste. Laboratory analysis of garbage should be carried out regularly to test its composition, calorific value, water content and other indicators to ensure that the garbage meets the requirements of incineration. At the same time, the operating status of the incinerator is monitored in real time, and the operating parameters are adjusted in time to ensure that the incineration process is stable and efficient.
Fourth, quality traceability management
Quality traceability management is an effective means to ensure the quality of waste. Through the establishment of a garbage quality traceability system, the source, collection, transportation, treatment and other links of garbage are tracked throughout the process to ensure the traceability of garbage quality. Once a garbage quality problem is found, the source of the problem can be quickly located and measures can be taken to correct it in time.
5. Feed management
Feed management is a key part of ensuring the quality of waste. A strict feeding control system should be established to strictly screen and inspect the garbage entering the incinerator to prevent the garbage that does not meet the requirements from entering the incinerator. At the same time, the feeding process is monitored in real time to ensure the uniformity and stability of the feeding.
6. Classification and recycling
Sorting and recycling is an important way to improve the quality of garbage. Residents and enterprises should be promoted to classify garbage through publicity and education, policy guidance and other means. By sorting and recycling, the quantity of non-combustible waste and hazardous waste can be reduced, and the quality and calorific value of incinerable waste can be improved.
7. Equipment maintenance
Equipment maintenance is an important guarantee to ensure the quality of waste. The incinerator and related equipment should be regularly maintained and maintained to ensure the normal operation and stable performance of the equipment. At the same time, establish equipment maintenance files, record and analyze the maintenance of equipment, and find and solve potential problems in a timely manner.
8. Supervision and supervision
Supervision is an important guarantee to ensure the quality of waste. The government should strengthen the supervision of waste incinerators, formulate strict environmental regulations and standards, and monitor the entire waste treatment process. At the same time, the public is encouraged to participate in supervision, establish a complaint and reporting mechanism, and crack down on illegal acts.

By strengthening the work of pretreatment, garbage collection management, technical testing and quality monitoring, quality traceability management, feed management, classification and recycling, equipment maintenance, supervision and other aspects, the waste quality of urban solid waste incinerators can be effectively ensured. This will help improve the operating efficiency and environmental protection of the incinerator, and promote the sustainable development of the urban solid waste treatment industry.
