Yanggu Hanhai accelerates green and low-carbon transformation, with green electricity utilization rate reaching 16.2%
"Hanhai Sewage Treatment Plant adopts green energy efficiency solutions to comprehensively optimize the energy use process from the power generation side to the load side, achieving clean energy use and intelligent management. So far, the green electricity utilization rate has reached 16.2%, equivalent to annual savings. Standard coal is 430 tons and carbon dioxide emissions are reduced by 1300 tons." This is a set of data that the reporter recently learned from Hanhai Water Treatment Co., Ltd. in Yanggu County, Shandong Province.
Shandong Yanggu County Hanhai Water Treatment Co., Ltd. is a wholly-owned subsidiary of Goldwind Environmental Protection Co., Ltd., which is responsible for the treatment of industrial wastewater in the Urban area and economic development zone of Yanggu County. Since the start of the first phase of the project in 2005, it has continuously upgraded treatment processes and improved treatment capabilities. At present, the overall project adopts the advanced treatment process of "pretreatment +AAO+ magnetic coagulation sedimentation tank + filter + ozone contact oxidation". On this basis, Hanhai Sewage Treatment Plant actively responded to the national environmental protection policy and invested 46.8717 million yuan in pollution control facilities. It has been upgraded and renovated, and the effluent water quality has reached the surface level Class IV emission standard. At present, it can reduce COD6,438.945 tons and ammonia nitrogen by 1,292.5828 tons annually.
Du Cunyu, head of Hanhai Water Treatment Company, Ltd. in Yanggu County, introduced that in the "Double Hundred Leaps" sewage treatment benchmark comparison activity launched by the E20 environmental platform and the industry, Hanhai Sewage Treatment Company stood out among many selected projects and won the title of "Low Carbon-Energy Intensive Utilization Benchmark".
In order to reduce carbon emissions and achieve the goals of clean production and carbon neutrality, Yanggu Hanhai Sewage Treatment Co., Ltd. invested 6.371 million yuan to lay distributed photovoltaics with a capacity of 1,336.28kWp in the factory, supplemented by energy-saving equipment such as energy monitoring. and means. This measure not only provides green electricity, reduces energy costs, but also improves the energy structure and makes a positive contribution to carbon emission reduction.
In addition to remarkable results in carbon emissions, Hanhai Sewage Treatment Co., Ltd. also actively promotes reclaimed water reuse and rural sewage treatment projects, achieving the recycling of water resources and continuous improvement of the ecological environment. Part of the treated reclaimed water is used for reuse by industrial enterprises, providing supplementary water for Huancheng Canal and Liaoyang Gully, and also providing water for road washing, landscaping and farmland irrigation in the Urban area. In addition, it has also undertaken rural sewage treatment tasks in nearby villages, further improving the level of rural domestic sewage treatment and assisting rural ecological revitalization.
As a provincial environmental education base, Hanhai Sewage Treatment Co., Ltd. actively fulfills its environmental social responsibilities, opens environmental protection facilities to the public, and carries out various environmental research activities and popular education activities. By demonstrating the "transformation" process of sewage and popularizing water resource protection knowledge, Hanhai Sewage Treatment Co., Ltd. has played a good role in stimulating and enhancing public awareness of ecological and environmental protection.
Du Cunyu said that Hanhai Sewage Treatment Co., Ltd. will continue to adhere to the concept of green development, continuously innovate and improve treatment technologies and management models, accelerate green and low-carbon transformation, and help build beautiful Shandong.
