"You didn't smell it when you came, did you?"
"Nope."
"This is because Haichuang has always put environmental protection first."
Suiyang Haichuang Environmental Protection Technology Co., Ltd. (hereinafter referred to as "Suiyang Haichuang") is located in Gaofangzi Village, Puchang Town, Suiyang County, Zunyi City, several European-style buildings stand like castles, they are not only a visual enjoyment, but also the green core of domestic waste treatment in Suiyang County. Yang Peisheng, deputy general manager of the company, revealed to us how to transform "useless" domestic waste into "useful" wealth here.
Since its establishment on September 17, 2019, Suiyang Haichuang has shouldered the important mission of domestic waste treatment in Suiyang County and even Zunyi area. The company covers an area of 76.19 acres, with a designed daily incineration capacity of up to 400 tons of domestic waste and an annual waste processing capacity of not less than 146,000 tons. Through the introduction of cutting-edge technologies such as "mechanical grate furnace waste incinerator + waste heat boiler + steam turbine generator set + combined process flue gas treatment device", Suiyang Haichuang not only realizes the harmless treatment of garbage, but also converts it into clean power resources, injecting new impetus into local sustainable development.
The establishment of Suiyang Haichuang has allowed Suiyang County to bid farewell to the traditional landfill method and move towards a new way of resource utilization of domestic waste. After the county's domestic garbage is collected in a unified manner, it is transported to Suiyang Haichuang for professional treatment. In the incinerator, these former "wastes" are "reborn" and finally converted into electric energy, which is delivered to thousands of households through the power grid, illuminating the lives of more people.
Since the start of construction in March 2020, Suiyang Haichuang has completed a gorgeous transformation from construction to production in less than a year and a half. Since it was officially put into operation on June 30, 2021, the company has received and processed about 431,800 tons of domestic waste, with a power generation capacity of up to 154 million kWh and a power generation capacity of 60 million kWh a year. This achievement not only improved the living environment of Suiyang County, but also made great contributions to the creation of a healthy and civilized county.
In the garbage crane operation room, the staff precisely operates the mechanical handle to control the crane grab to quickly grab the garbage in the garbage pit and put it into the incinerator.
"All the garbage collected will be piled up here. All household waste can be reborn here and turned into more meaningful power generation energy. The slag after combustion can also be sorted again as a building material and cement mixture, so that the waste can truly realize the useful value conversion and achieve comprehensive utilization of resources. Yang Peisheng said.
The company implements a working system of four shifts and three shifts, each shift of 8 hours, to ensure that the daily processing capacity reaches 450 tons. At the same time, the newly transported household waste is stored in piles to drain the water and promote fermentation, creating optimal conditions for the combustion process.
The central control room is the "brain" of the project, and the staff monitors the production and operation of the project in real time through the centralized decentralized control system to ensure that the environmental pollution sources meet the emission standards. The entire process is highly automated, which not only improves work efficiency, but also improves environmental protection.
In terms of "three wastes" treatment, Suiyang Haichuang also performed well. The leachate is reused through an advanced treatment system and is not discharged; The flue gas purification system meets the national standard and the EU 2000 standard to ensure that the emission is harmless; Slag and fly ash are scientifically treated as building materials or landfills, maximizing the use of resources.
The operation of Suiyang Haichuang not only solves the problem of domestic waste treatment in Suiyang County, but also promotes the supply of local power resources and the development of related industries. At the same time, the company has promoted the development of environmental protection by standardizing garbage disposal measures, and improved the public's awareness and participation in environmental protection. In addition, the company has created local employment opportunities and promoted the transfer of labor and economic development.
"Looking forward to the future, Suiyang Haichuang will continue to adhere to the development concept of 'green, environmental protection and innovation', and continuously improve the technical level and service quality. We will continue to devote ourselves to the harmlessness, reduction and resource treatment of domestic waste, and contribute to the green development of Suiyang County and the wider region. With the stable operation of the project and the continuous improvement of technology, Suiyang County will continue to move forward on the road of green development. Yang Peisheng said.
