本文主要研究内容
作者魏攀龙（2019）在《城市水体表观污染分类及其关键影响因素研究》一文中研究指出：至目前为止,城市水体主要功能为景观功能,但是由于受到外界污染物的影响,城市水体的景观功能也逐渐消失,城市水体已不能满足愉悦人民的功效,而城市水体由于受到外界污染物的影响而引起人体感官不适的现象正是水体表观污染。城市水体表观污染现象的存在,不仅对城市生活环境的保持造成严重的困扰,而且严重影响城市生态环境的健康发展,这一问题已经引起政府部门关注,恢复城市水体景观功能成为城市水体污染治理的首要目标,而现有的水质评价方法和针对表观污染极端水体的评价方法,均不能满足人们对水体表观质量进行评价的需求。为弥补现行城市水体评价方法的不足和局限性以及满足水体表观污染评价的实际需求,本课题组构建了一种表征方法——表观污染指数法(SPI),该方法已于2015年被纳入《城市黑臭水体整治工作指南》,但该方法仅仅是表征手段,无法对表观污染水体的成因做出分析,更不能对表观污染水体的预防及治理技术方案的确定提供指导意义。本研究对象为苏州城市水体范围内符合研究目标的水体,通过对不同表观污染水体成因分析,筛选出不同表观污染水体的特征指标或特征值,构建出表观污染分类方法,同时探究特征指标或特征值的影响因素。研究结果可对表观污染水体的预防策略及修复方案,提出不同表观污染类型针对性治理方案具有指导意义。本研究主要得到以下结论:(1)对不同表观污染类型水体进行定义并明确了其各自显著特征:有机主导型表观污染水体主要污染物质为有机物,包括水体黑臭现象或藻类过渡繁殖所导致水华现象,水体呈现黑色、墨绿;无机主导型表观污染水体主要由无机物(泥沙等无机颗粒)引起,浊度偏高,水体多呈现黄色,土黄色;营养主导型表观污染水体主要由水体中无机营养物(N、P等)引起,水体表观良好,呈现清澈、无明显悬浮物、绿色等特征;混合型表观污染水体处于以上三种表观污染类型之间,由无机物、有机物等共同引起,具有向有机主导型、无机主导型、营养主导型中某一类型转变的特点,水体多呈现黄绿色、灰色。(2)通过对苏州市河道水质指标监测,并采用统计学方法对数据进行归纳分析,构建出优先判别次序为无机主导型>有机主导型>营养主导型>混合型,无机主导型表观污染水体判定条件为Im/Tur<0.08 mg/L/NTU;有机主导型(黑臭)表观污染水体判定条件为ORP<0 mv;有机主导型(水华)表观污染水体判定条件为DO/DOs>1且Chla>50μg/L;营养主导型表观污染水体判定条件为Tur<15NTU且Chla<50μg/L的表观污染水体分类方法;指标体系验证证实了该方法所选特征指标或特征值的准确性,进一步增强了表观污染分类方法的可行性、合理性。(3)采用相关性分析与逐步回归分析法相结合的方法分析所采集水体特征指标或特征值受到外部影响的关键因素,发现:有机主导型(黑臭)表观污染水体关键影响因子为溶解氧和高锰酸盐指数;有机主导型(水华)表观污染水体关键影响因子为水体实际温度及溶解氧;对于无机主导型表观污染水体,无机主导型表观污染水体关键影响因子为高锰酸盐指数与浊度,此外来往船只对水体的扰动作用亦不可忽视;对于营养主导型表观污染水体,总磷、高锰酸盐指数、温度和氨氮为营养主导型表观污染水体的关键影响因子,并对不同表观污染类型水体提出一定的防治措施。
