Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The urban and rural solid waste comprehensive treatment system of the invention is described below with reference to fig. 1 to 9.
At present, solid waste handles the facility construction overall arrangement dispersion, and the land utilization fragmentation, each department establishes and lacks effective cooperation between the institute, handles metabolic process and easily causes secondary pollution, and solid waste integrated utilization is low, and garden overall stability and anti-risk ability are not high, the effect of gathering is not obvious, handles the facility "neighbour avoid" effect and is showing very much, becomes the bottleneck of many city economy social sustainable development.
With the improvement of urban and rural integrated development degree and the popularization of garbage classification policy in China, the urban and rural solid waste production amount is increased rapidly, and a systematic solution and a new operation mode suitable for urban and rural solid waste area-based cooperative disposal are urgently needed to be constructed.
