The benefits of Co-processing kitchen waste and domestic waste are shared resources, lower costs, environment-friendly and economic benefits. A typical case is the co-processing of food waste and biological waste in Yanzhou District, Jining Province. First, the Co-processing of kitchen waste and household waste can realize resource sharing and reduce construction and operation costs. For example, the waste-to-energy plant in Yanzhou District, Jining, is on the same site as the kitchen waste project, sharing infrastructure such as water, electricity and sewage treatment systems, the redundant construction of ancillary facilities is avoided, thus reducing the investment and saving the cost. Second, this collaborative processing model can also complement each other, resulting in four major effects to promote aggregation, it includes the cost reduction of water and electricity sharing, the comprehensive treatment of waste water and gas, the utilization of waste residue and odor as a resource, and the benefit increase of biogas and steam sharing. For example, the kitchen waste treatment project daily electricity to enjoy the domestic waste incineration plant low-cost electricity, daily water use incineration project sewage treatment facilities after the treatment of reclaimed water. Third, the kitchen waste treatment station not only provides a win-win solution for ecological protection and economic benefits, but also through scientific treatment, can reduce the harm of garbage to the environment, and achieve effective recycling of resources, at the same time, it produces a lot of renewable resources, such as organic fertilizer, waste oil and fat, etc. . Finally, the co-treatment process of restaurant wastewater and domestic waste can treat both restaurant wastewater and domestic waste leachate simultaneously, which reduces the treatment equipment and area, and reduces the treatment cost. The water treated by this process can meet the national discharge standard, and it can also obtain certain resource value, such as biogas, etc.
