Abstract：
Inorganic chlorine is susceptible to water and soil salinization due to its non-degradability and high mobility. To clarify the environmental risks associated with the active inorganic chlorine in municipal solid waste (MSW), the specific characteristics and contributions of inorganic chlorine in different MSW categories were investigated in this study. MSW samples were collected from eight representative waste classification residential areas in Hangzhou, China. It was found that the inorganic chlorine content in different MSW categories varied significantly (0-113 mg/g). Perishable waste, paper, and plastic were found to be the main sources of inorganic chlorine in MSW. A four-category classification system was used to quantify the contribution of inorganic chlorine from each waste category. It was found that the misclassification of inorganic chlorine contributions from perishable waste and other waste accounted for 51.96% and 48.04%, respectively. However, when correctly classified into the four-category system, their contributions were reduced to 67.14% and 30.65%, respectively. Therefore, MSW classification showed a significant reduction in the overall contribution of inorganic chlorine. The misclassification reduces the contribution of inorganic chlorine to 48.04%, while correct classification increases the reduction to 69.35%.
摘要：
无机氯由于其不可降解性和高迁移率而容易受到水和土壤盐渍化的影响。为了澄清与城市固体废物(MSW)中活性无机氯相关的环境风险，在这项研究中，研究了不同类别MSW中无机氯的具体特征和贡献。收集了杭州8个有代表性的垃圾分类住宅区的生活垃圾样本,中国。发现不同MSW类别中的无机氯含量差异显着（0-113mg/g）。易腐废物,paper,发现塑料是MSW中无机氯的主要来源。使用四类分类系统来量化每个废物类别中无机氯的贡献。发现易腐废物和其他废物中无机氯贡献的分类错误占51.96％和48.04％，分别。然而,当正确分类为四类系统时，他们的捐款减少到67.14%和30.65%，分别。因此,MSW分类显示无机氯的总体贡献显著降低。误分类使无机氯的贡献率降至48.04%,而正确的分类将减少到69.35%。
