基于节能环保的厕纸处置方式调查与研究

Investigation and Research on the Disposal of Toilet Paper Based on Energy Saving and Environmental Protection

目前对厕纸使用后处置方式无规范要求,对于国人厕纸使用后处理方法缺少统计资料,因此,对居民在生活中将使用后的厕纸丢进马桶中冲走,还是将其丢入纸篓中作为固废处理的问题,通过对全国一定范围内的居民生活习惯的调查研究,分析调查结果,得到厕纸处置现状.实验监测厕纸置于水中产生各种污染物对水体环境的影响情况,得到厕纸进入下水道对污水处理厂的污染物贡献占比,进而分析厕纸入下水道的环境影响.对厕纸作为固废处理对环境的影响情况进行了分析.结果表明,居民在日常生活中将厕纸使用后直接丢进马桶的占66.2%,丢进纸篓中的占33.8%;若厕纸全部入下水道化学需氧量排放量占0.097%,氨氮排放量占0.096%,可生化性评价指标均值达0.45;若厕纸全部作为固废处理,其排放量约占生活垃圾总清运量的3.09%,同时带来卫生问题.最后,得出了将使用后的厕纸丢进马桶中处理是更加节能环保的处置方式.

At present,there was no specification requirement and lack of statistical data on the used toilet paper proposal in China.Therefore,to get the status of toilet paper disposal,a survey on residents′habits whether they threw the toilet paper in the toilet to wash it away or threw it in the wastebasket as a solid waste was conducted within a certain range of China.To assess the environmental impact of toilet paper into the sewer,various pollutants caused by toilet paper in water were monitored in the experiment and the contribution of pollutants to sewage treatment plant was studied.The effect of toilet paper as solid waste on the environment was also analyzed.The result showed that the proportion of residents who threw toilet paper directly into toilet in daily life were 66.2%and 33.8%of the residents preferred to drop the toilet paper into waste baskets.If all toilet paper were thrown into the sewer,the chemical oxygen demand emissions would account for 0.097%and the ammonia account for 0.096%.The mean B/C value of the indicator of biodegradability was 0.45.If all the toilet paper were treated as solid waste,the discharge amount would account for 3.09%of the total amount of household garbage,which would also bring health problems.Finally,it is concluded that throwing the toilet paper into the toilet is a more energy saving and environmental protection disposal method.
