solid waste treatment
In recent years, Yongqing Environmental Protection's solid waste treatment industry chain has been continuously improved, with steady development of various businesses and more refined management to ensure stable operation. We have established an operational management system for the entire industry and process, including garbage collection, garbage incineration power generation, leachate treatment, tail gas treatment, and finally incineration fly ash treatment.
core technology
Core technology
Garbage incineration power generation enterprise: Yongqing has mastered the complete and domestically advanced core technology of garbage incineration power generation. Creating a "composite incinerator" can reduce the concentration of dioxin emissions to less than 0.08ng/m ³, which is better than the EU standard of 0.1ng/m ³, and the concentration of nitrogen oxide emissions to less than 120mg/m ³, which is better than the EU standard of 200mg/m ³. The concentration of pollutant emissions is also lower than the national standard.

solid waste treatment
In recent years, Yongqing Environmental Protection's solid waste treatment industry chain has been continuously improved, with steady development of various businesses and more refined management to ensure stable operation. We have established an operational management system for the entire industry and process, including garbage collection, garbage incineration power generation, leachate treatment, tail gas treatment, and finally incineration fly ash treatment.
The company fully owns 2 garbage incineration power generation projects, participates in the one-time construction and operation of the national large-scale garbage incineration power generation project - Changsha Municipal Solid Waste Incineration Power Plant, and fully owns 5 front-end garbage collection and transportation projects. There is a provincial-level hazardous waste disposal center in Gansu Province - Gansu Hexi Environmental Protection Technology Co., Ltd. The mature market, complete industrial chain, and comprehensive technical support have enabled Yongqing Environmental Protection to take solid steps in the field of hazardous waste disposal.
The company's independent innovation and continuous research and development capabilities have won multiple national awards. We have established extensive communication and cooperation relationships with peers in Europe, America, Japan, and other countries, and have maintained close cooperation with domestic research institutions such as the Chinese Academy of Environmental Sciences, Tsinghua University, Zhejiang University, Yunnan University, and Chongqing University for a long time. The company has its own "technology research and development center" and pilot base, providing strong technical support for solid/hazardous waste disposal.

The concentration of pollutant emissions is also lower than the national standard.
Six core technology systems for waste to energy generation
Create a composite incinerator
Creating and possessing advanced composite incinerators, Yongqing has become a domestic enterprise that independently researches and produces waste incinerators. The thermal burn off rate of the grate produced after garbage incineration is 1.25-2.5%.
3T Combustion Control Technology (ACC)
Automatically control combustion to reduce the production and emissions of harmful substances such as dioxins, nitrogen oxides, and carbon monoxide.
The key indicators of flue gas purification are superior to EU standards
Smoke purification technology can make dioxin emissions better than EU standards, while other pollutant emissions meet national standards.
Garbage leachate "*"
The effluent quality meets relevant national standards, and the concentration of the concentrate is reduced to within 15%. It can be reused within the waste incineration power plant, achieving "*".
Slag fly ash treatment system
The slag is subjected to high-temperature harmless treatment for brick making, and the comprehensive utilization rate of slag can reach 98%; The fly ash treatment adopts intelligent integrated equipment and control technology, accurately adding stabilizers to reduce unit processing costs by 20%.
Collaborative incineration system
Obtained national invention. The system can make full use of the favorable conditions of the domestic waste incineration power generation system to co incinerate and treat urban sludge, food waste and medical waste, which is conducive to the construction of an "upgraded waste incineration power plant and a reduced version of the environmental protection vein industrial park" model, achieving the effect of saving investment, reducing floor area, saving energy consumption and reducing treatment costs.
Disposal Process
Integrated solution provider for urban and rural environmental sanitation
Yongqing Environmental Protection has now formed a complete integrated service system for urban and rural environmental sanitation, promoting the comprehensive implementation of the 'new fashion' of garbage classification.
We share the burden of the government with high standard cleaning and sanitation services, efficient garbage transfer services, and high-level terminal disposal services; Comprehensive evaluation, pay based on performance.
The company has implemented multiple "urban and rural household waste collection and transportation" projects in Xinyu, Anren, Wugang and other places, and invested in the construction of multiple household waste incineration power plants in Changsha, Hengyang, Xinyu and other places.
