Urban Vein Industrial Park
The vein industrial park advocated by GDCE takes the waste incineration power generation project as the core. It efficiently integrates projects such as kitchen waste treatment, sludge treatment, domestic sewage treatment, high-concentration sewage treatment, e-waste dismantling, and waste resource recycling. It has become a comprehensive treatment center for the reduction, harmlessness, and resource utilization of urban solid waste. At the same time, the centralized treatment and disposal method is convenient for government supervision and the control of pollution sources. It has become a highlight and an indispensable part of the future urban infrastructure construction, playing a significant role in promoting the sustainable development of the city. The overall planning objectives of the urban vein industrial park are: to serve the city, achieve the three major functions of resource utilization of urban waste, environmental protection culture education display, and comprehensive management of environmental sanitation facilities, and build it into a modern and intensive circular economy park that is environmentally friendly, shares resources, and is sustainable.
Domestic Waste Incineration and Power Generation Project
Taking municipal domestic waste as fuel, the mechanical grate furnace incineration treatment technology is adopted. The incineration furnace and the waste heat boiler are arranged in an integrated manner. The flue gas treatment technology of SNCR denitrification in the furnace + semi-dry acid removal + dry spraying + activated carbon adsorption + bag dust removal is used. The advanced DCS computer automatic control system in the international measurement and control field is adopted for system control. The entire process system of the domestic waste incineration and power generation project is composed of a waste pretreatment system, a waste feeding system, a waste incineration system, a flue gas purification treatment system, a slag discharge system, a steam and water system, an automatic control system, a chemical water treatment system, an electrical system, a steam turbine power generation system, a power plant access system, etc.
EFB Incineration and Power Generation Project
The water-cooled grate incineration technology is used. It is specially designed for the incineration of EFB biomass fuel and adopts adiabatic combustion, with high combustion efficiency. The temperature of the flue gas entering the boiler is reduced to below 600℃, which greatly reduces the problem of ash accumulation, and the annual operation time can reach 8,000 hours. In addition, flue gas recirculation is adopted to gasify the biomass fuel in an oxygen-deficient state, which further improves the combustion efficiency and reduces the pollutant emissions. Taking the daily treatment of 700 tons of EFB as an example: The EFB incineration and power generation project includes 2 EFB boilers with a capacity of 350 tons per day and 1 15MW pure condensing steam turbine generator set, as well as auxiliary systems and equipment.
Kitchen Waste Treatment Project
The main processes of the kitchen waste treatment project: pretreatment + three-phase separation (oil extraction) + carbon source preparation. It includes: negative pressure unloading system, pretreatment system, anaerobic hydrolysis, anaerobic acidification, membrane filtration and purification system, sewage treatment system and deodorization system, as well as comprehensive facility services such as environmental monitoring, power transformation and distribution, water supply and drainage, etc. The kitchen waste undergoes membrane filtration and purification to prepare carbon sources after pretreatment and anaerobic dehydration. The odor is collected dispersedly and treated centrally to meet the discharge standards.
Sludge Treatment Project
The sludge treatment adopts an integrated organic solid waste treatment system: By means of the slow rotation of the fully enclosed rotary kiln drum, the sludge is slowly moved from the feeding end to the discharging end. During this process, the materials are mixed and oxygenated, providing a superior growth environment for microorganisms. The aerobic fermentation reaction occurs rapidly, the temperature of the materials is increased, and the degradation of organic matter is promoted. A high temperature of 70-75℃ is maintained for about 5-7 days. Under the action of high temperature, harmful insect eggs and the like can be killed. At the same time, the reduction, harmlessness, stabilization and resource utilization of organic solid waste are achieved.
Water Environment Treatment Project
In the water environment treatment, relying on technologies such as efficient treatment of domestic sewage, ecological restoration and treatment of water bodies, treatment of polluted wastewater, and intelligent management of ecological treatment, systematic and comprehensive restoration and treatment solutions are provided for various complex water body environments, including urban areas, rural areas, rivers, lakes, mines, hospitals, etc.
Palm Oil Wastewater Treatment Project
The treatment of palm oil wastewater adopts the process route of "oil separation/grating tank + pretreatment system + equalization tank + anaerobic reactor + membrane bioreactor (A/O+MBR)". The wastewater passes through the oil separation grating and enters the elliptical stacking machine for solid-liquid separation treatment. The separated liquid enters the three-phase centrifuge for oil extraction, and the wastewater goes into the equalization tank. The wastewater in the equalization tank is pumped into the anaerobic reactor, generating biogas and reducing the content of organic matters. Finally, it is further treated through the membrane bioreactor and discharged up to the standard.
