摘要
为了提高生态文化旅游景点中塑料垃圾的回收率,提出生态文化旅游景点塑料垃圾污染控制方法。通过设计循环式分离土壤中塑料垃圾的装置,选取浮选试剂,测试不同试剂对塑料垃圾的回收率,利用浮选试剂和过氧化氢溶液消解后,检测塑料垃圾的尺寸和质量变化情况。结果表明,NaI饱和溶液对不同聚合物类型、不同尺寸和不同形状的塑料平均回收率分别为98.9%、98.7%和97.5%,利用NaI饱和溶液和过氧化氢溶液消解后,影响塑料的程度不显著,说明NaI饱和溶液回收塑料垃圾具有高效性,实现了生态文化旅游景点的生态环境保护。
In order to improve the recovery rate of plastic waste in eco-cultural tourist attractions,the pollution control methods of plastic waste in eco-cultural tourist attractions were put forward.By designing a circulating device for separating plastic waste from soil,the study selects flotation reagents to test the recovery rate of plastic waste with different reagents.After digestion with flotation reagent and hydrogen peroxide solution,the changes of size and quality of plastic waste were detected.The results show that the average recovery rate of saturated NaI solution for plastics of different polymer types,different sizes and different shapes is 98.9%,98.7% and 97.5%,respectively.After digestion with saturated NaI solution and hydrogen peroxide solution,the degree of influence on plastics is not significant,indicating that saturated NaI solution has high efficiency in recycling plastic waste.The ecological environment protection of ecological cultural tourist attractions has been realized.
