Research On The Planning And Design Of Garden Waste Disposal Site

With the continuous enhancement of the concept of green development,people pay more and more attention to the construction of social ecological civilization.Therefore,the area of green space in cities around the world is also increasing year by year.The amount of garden waste such as grass and leftover flowers has also risen rapidly.At present,most of the garden waste is disposed of by incineration or landfill together with domestic waste.However,this kind of treatment will not only cause environmental pollution,but also waste land resources,which will affect human health and the construction of ecological cities.As a kind of organic waste,garden waste has high ecological value,but it has been neglected and wasted.In recent years,my country has been vigorously promoting the recycling and harmlessness of urban solid waste.At present,some cities have begun to collect,process and reuse garden waste in a centralized manner,so that it"comes from nature and belongs to nature".With the further strengthening of the 19th National Congress of the Communist Party of China,"Clear waters and green mountains are invaluable assets",landscape construction will inevitably lead to a new climax.Therefore,how to handle and utilize the increasing garden waste more scientifically and rationally to turn waste into treasure,becoming an available resource,is the question to be explored in depth in this study.From the perspective of landscape,this paper takes the central urban area of Qingyang County,Anhui Province as the research object,firstly defines the area where garden waste can be collected in the study area,and makes detailed statistics on the area type,spatial location and area size.Secondly,referring to the way of estimating the amount of garden waste in each city,the resource amount of garden waste in the study area was calculated.Then,according to the characteristics of garden waste and the actual situation of the study area,the appropriate recycling method of garden waste is selected for the study area and the collection mode system of the study area is designed.Then use GIS spatial analysis technology to screen out the areas suitable for the establishment of garden waste disposal points,as well as the type and scale of equipment each disposal point should be equipped with.Finally,taking Furong Lake Park as an example,the specific planning and design of the nearest disposal point for garden waste in the park is carried out.The following are the main findings:(1)The green area of the research area that can collect garden waste is 298.96hm~2,including98.74hm~2 of park green space,75.56hm~2 of protective green space,0.64hm~2 of square land,97.41hm~2 of auxiliary green space,and 26.61hm~2 of regional green space.In addition,among the types of green space that can be collected,park green space includes three types:comprehensive park,special park,and amusement park;auxiliary green space includes two types of auxiliary green space for roads and transportation facilities,and auxiliary green space for residential land;regional green space includes production green space 1 type.(2)The amount of garden waste generated in the study area is about 3819.43t.Among them,the park green space is 987.4t;the protective green space is 755.62t;the green space in the square land is 9.53t;the auxiliary green space is 949.07t;and the regional green space is 1117.82t.(3)After comparing the advantages and disadvantages of various resource utilization methods,combined with the industrial development status of Rongcheng Town,Qingyang County,Anhui Province,it is concluded that the garden waste in the study area is suitable to be produced into organic fertilizer and organic mulch,and then put into the city Used in landscape construction.In addition,in order to facilitate the collection and transportation of garden waste and improve the treatment efficiency,three types of stations,namely the nearest treatment point,the transfer treatment station and the centralized treatment plant,were designed to deal with the garden waste in the study area,and cooperated with the"fixed-point collection".-Carrying with cutting and transporting-centralized collection"collection mode to collect and operate.(4)Considering factors such as land use type,building,traffic,watershed,slope,and area of candidate areas,it is recommended to establish 3 nearby treatment points in the central urban area(each treatment point is equipped with 1,2,and 1 Integrated OAR equipment,a total of 4),4transfer processing stations(each station is equipped with 1 pulverizer,a total of 4),1 centralized treatment plant(equipped with complete mechanical devices),and according to the amount of garden waste resources The density and spatial location of transfer processing stations divide the central urban area into 4 collection areas,corresponding to 4 transfer processing stations respectively.(5)Carry out a detailed analysis on the construction of Furong Lake Park near the processing point.Since 2 sets of equipment are required,two candidate areas suitable for the establishment of the site have been determined,and the functional layout of the site and the traffic flow line have been considered in depth.and design.
