Analysis of the status of rural garbage and sewage treatment in Shanxi Province, 2016-2018 / 公共卫生与预防医学

ABSTRACT

Objective To understand the status and dynamic changes in the treatment of rural garbage and sewage in Shaanxi Province and provide the basis for relevant departments to formulate policies and measures. Methods Every year from 2016 to 2018, 600 administrative villages in 30 agricultural counties were randomly selected as monitoring points, and 3 000 households were selected as monitoring households. Monitoring data was obtained through data reading, interviews, and on-site observations. Results The three-year rural population coverage rate of the garbage treatment plant was 28.31%, 36.10%, 39.36%, respectively, and the sewage treatment plant coverage rate was 12.27%, 20.39%, 15.02%, respectively. The annual differences were statistically significant（χ2=23.24、22.42，P=0.00）. The proportion of monitoring points for the three-year unified collection of domestic garbage was 30.50%, 43.67%, 51.00%, respectively, and the percentage of monitoring points for incineration garbage was 16.67%, 15.00%, 8.33%, respectively, and the annual differences were statistically significant（χ2=53.25、20.19，P=0.00）. The proportion of domestic sewage discharge monitoring points through pipelines was 12.67%, 11.17%, 31.17%, respectively, and the proportion of monitoring points discharged into treatment plants was 4.33%, 6.00%, 15.17%, respectively, and the annual differences were both statistically significant（χ2=99.45、52.50，P=0.00）. Conclusion In recent years, the rural garbage and sewage treatment situation in Shaanxi Province had improved, but there was still much room for improvement. It is recommended to increase environmental protection publicity and government investment, strengthen daily supervision, pay equal attention to construction and management, control the random stacking and discharging of garbage and sewage, and enhance the disposal rate of garbage and sewage.
