The bustling city is operating day and night. In Guangzhou, about 30,000 tons of garbage is generated every day. Every morning, watching the neat streets of the day, many citizens will have such doubts -where did the domestic garbage go? What did they eventually become? These problems can be found in the resource thermal power plant distributed around Guangzhou.

Practicing the construction of ecological civilization and creating a beautiful living environment, the reporter recently visited the third resource thermal power plant in Guangzhou to see that in the three stages of the drying, combustion, and embers of waste incineration, the whole process practiced resource utilization and environmental impact on the use of resource utilization and environmental impact The principle of minimizing, in the waste incineration furnace that ignited the flames, the garbage generated by the urban life transformed into a gorgeous transformation here, and transformed into a clean electricity and exported to millions of households.

Where did the classified domestic garbage go?

At present, common domestic waste disposal methods are mainly three types: landfill, compost, and incineration power generation. However, landfills have a large amount of land, and the risks of environmental pollution in landfills are large, which can easily cause leakage and contaminated soil and groundwater. Certain compost is used in rural areas. The processing speed is slow and the scale is small. Therefore, incineration power generation, which has less land resources, fast treatment speed, less secondary pollution, and reuse of resources has become the mainstream garbage treatment method. In recent years, Guangzhou has formed a new pattern of "burning, supplemented by biochemistry, supplemented by biochemistry, and landfilling".

Under the green mountains, the two full -loaded gray coating garbage clearing vehicles slowed down along the Panshan Highway. On the soothing hillside on the roadside, it was dotted with carefully maintained gardening landscapes. In the embrace of the mountains in Huangpu District, Guangzhou, a building complex stands with blue and white colors. This place similar to the park is the largest circular economy industrial park in China, Guangzhou Fushan Circular Economic Industrial Park. The destination of these garbage clearance vehicles is the third resource thermal power plant in Guangzhou in the park. The domestic garbage loaded on the car will be gorgeous into clean power.

The waste incineration process includes three stages: drying stage, burning stage, and an embers. The reporter saw at the scene that in a transparent large -scale "sealed tank", the garbage cleared car poured here the small door opened from one side. Due to the large water content of garbage, they must first dry and fermented in the storage pit, so as to increase the heat value to be more conducive to subsequent incineration. Above the storage pit, a huge garbage grab can grab five tons of garbage at a time, and the operator is operating to send the garbage to the incinerated furnace. It is understood that the garbage is also filtered out of sewage, and these filter fluids will be transported to the seepage liquid treatment plant to treat production water.

What did the garbage finally become?

The waste incineration furnace burns the flames of the bear. The temperature of the furnace is as high as 850 to 1100 degrees Celsius. Electricity. It is reported that according to the current technology, it can generate about 400 degrees per ton of garbage.

In the third resource thermal power plant in Guangzhou, the waste incineration process is also equipped with environmental protection projects such as air condensate system, flue gas purification system, wastewater treatment system, and ash treatment, to maximize the cleanization and resource of domestic waste treatment. The project flue gas purification system adopts the world's leading "SNCR+semi -dry method+activated carbon jet+bag dust collector" process. The lime and the harmful gases in it are chemically reacting to transform it into harmless substances. Activated carbon can adsorb the two evils and heavy metal particles. The cloth bags of special materials can filter dust and harmful substances to purify and emit smoke.

In the final stage, the non -incinerated substances in the waste incineration will produce scum. According to reports, the treatment of furnace slag generally contains metal sorting and recycling, and comprehensive utilization of building materials. In the Fushan Circular Economic Industry Park, there is a path paved with environmentally friendly bricks. This kind of environmentally friendly brick can also be used in municipal engineering construction, and has the advantages of lightweight and water transparency. After maximizing the recycling of resources, the remaining fly ash of waste incineration will eventually be transported to the landfills for area landfill after being solidified.

The treatment of garbage resources helps improve the living environment

Guangzhou's third resource thermal power plant is just a small microcosm of Guangzhou's domestic waste resource treatment. In addition, the processing capacity of the resource thermal power plant has been completed before. At present, the daily processing capacity of Guangzhou's domestic waste incineration design has exceeded 30,000 tons. The earth improved the living environment of Guangzhou. In June 2022, the newly released "14th Five -Year Plan for the Development of the Urban Infrastructure in Guangzhou" proposed that by 2025, the city's domestic sewage collection was fully covered, and native domestic waste zero landfills.

Promoting the construction of classification and treatment facilities, Guangzhou is still continuously exploring the new path of old landfill governance, such as using resource thermal power plants to gradually digest aggressive garbage, explore diversified ways such as adjustment through facility capacity structure, upgrade and transformation, and collaborative disposal , Further enhance the production capacity of biomass treatment facilities such as Fushan, Datian Mountain, and promote the intelligence of Baiyun Likeng, Baiyun Xingfeng, Huangpu Fushan, Nansha Dagang, Zengcheng Bitan, Conghua Tankou, Huadu, and Huadu Intelligent Construction.

In the future, Guangzhou's domestic waste resource processing capacity will continue to increase, and the second phase, fourth, fifth, sixth, and seventh resource power plants of the Fushan Circular Economic Industrial Park will continue to complete the Fushan Circular Economic Industrial Park. The construction of resource thermal power plants, and start a new resource thermal power plant planning and research work, help the development of the circular economy, and create a more beautiful urban ecological environment.
