Analysis On The Production Characteristics And Classification Eeffect Of Domestic Garbage In Typical Urban Communities In My Country

With the acceleration of my country’s urbanization process,the collection,transportation and disposal of urban residents’ domestic waste has increasingly hindered the rapid development of urban economy.The domestic waste of urban residents has become one of the inevitable important problems in urban development.In view of the urban residents’ domestic waste management policy,it is of great significance to promote the sustainable development of society and economy.Therefore,the treatment effect of urban residents’ domestic waste has attracted more and more attention,and it is also the main focus of environmental authorities in many countries around the world.In order to deeply study the policy layout of waste management and further optimize the management plan,it is particularly necessary to improve the performance of waste management and improve economic benefits.With the deepening of China’s reform and opening up,the country’s economic development goals are constantly changing.At the same time,the policy layout of waste management has also changed.The implementation of domestic waste classification is an important link in promoting environmental construction and social development.Since the implementation of the domestic waste classification pilot policy,how to evaluate the implementation effect of domestic waste classification and clarify the factors affecting the classification effect has become the focus of research.Based on four different types of Beijing community bungalow alley,no cleaning service open area,low volume rate gated communities and high volume ratio gated community as the research object,the same type in wuhan community as reference object,through field visits,investigation and comprehensive analysis of the two regions of garbage classification policy implementation present situation,effect and basic experience and existing problems,On this basis,it is suggested to improve the national awareness of household garbage classification by clarifying the overall goal of policy implementation,improving the supporting facilities for policy implementation,and increasing publicity.This research adopts the methods of questionnaire survey,interview,household survey and site timing.The residents of this questionnaire survey are widely distributed in 16 districts in Beijing,and the age group distribution is relatively even.A total of 790 questionnaires were collected online and offline.After analysis,Beijing residents’ awareness of garbage classification has been significantly improved,and they can actively cooperate with each community.The older you are,the more you can accept garbage classification,and are more willing to actively cooperate with garbage classification;corporate staff,staff of state organs,staff of public institutions,students,etc.Where the value lies,they are also willing to participate in activities related to garbage classification;residents with high incomes pay less attention to garbage classification than those with low incomes,and are unwilling to actively carry out garbage classification;people with higher education levels are more willing to devote themselves to the ranks of garbage classification to actively cooperate with the work of garbage sorting.Factors such as age,education level,economic level,occupation,season and waste site staff will all affect residents’ waste sorting behavior,but site staff factors play a major role.Both Beijing and Wuhan adopt four classifications for garbage classification,and conduct household-type garbage source surveys in four types of communities in Beijing and high-volume-ratio closed communities in Wuhan,as well as regular and fixed-point data collection for four seasons.A four-season survey in Beijing communities shows that most of the domestic wastes of Beijing residents are kitchen waste and other wastes as the main components,and kitchen waste and other wastes account for more than 90% of the total domestic waste quality.In the four seasons,the average amount of kitchen waste,other waste and recyclable waste generated by community households in autumn was the highest,which were 954 g,699g and 344 g respectively.Among the four different types of communities,the average daily production of kitchen waste and other wastes per household in the high plot ratio community is the highest,at 910 g and 807 g,respectively.The data collected at regular and fixed points at the collection site show that the accuracy of garbage classification of residents in high-volume-ratio residential areas is as high as 90%,and there is an increasing relationship in the four seasons of autumn,winter,spring and summer.The classification effect is the best.The main factor affecting the accuracy of garbage classification is the supervision of garbage site staff.
