摘要

基于对重庆市50处农村黑臭水体整治项目调查的基础上,构建了“压力-状态-响应-效益”(PSRB)框架模型,从压力、状态、响应、效益四个维度筛选确定评价指标,形成了评价指标体系.对已整治完成6个月以上的堰塘、沟渠和河流3种类型黑臭水体的11个典型案例进行了评价,并跟踪评价了其中堰塘型黑臭水体在2023年6、8、10月的整治效果.结果表明,压力、状态、响应、效益各维度权重分别为0.27,0.21,0.36,0.16,权重较高的负向指标(C₁₁、C₁₄、C₂₄、C₃₆)多于权重较高的正向指标(C₃₁、C₄₁),即农村黑臭水体整治虽然得到了积极响应,但整治完成的水体仍存在较大压力,获得效益有限.11个典型案例中,10个案例的整治效果等级为“有效”,1个案例为“合格”.压力维度中“水域人口负荷较大”、“截污纳管破损”、“黑臭底泥残留”以及响应维度中“水体整治投资较高”、“运维管护执行力度不足”是对整治效果带来不利影响的主要因素.

Abstract

Based on the investigation of 50 rural black and odorous water remediation projects in Chongqing, this study constructed a "Pressure-State-Response-Benefit" (PSRB) framework model, screened and determined the evaluation index from the four dimensions of Pressure, State, Response and Benefit, and formed an evaluation index system. Based on the investigation of 11 typical cases of black and odorous water specifically ponds, ditches, and rivers that had been remediated for over six months, an evaluation was conducted. Among these, the remediation effect of pond-type black and odorous water was tracked and evaluated in June, August, and October 2023. The results indicate that the weights of the four dimensions Pressure, State, Response and Benefit were 0.27, 0.21, 0.36, and 0.16, respectively. The negative indexes with higher weights (C₁₁, C₁₄, C₂₄, C₃₆) outnumber the positive indexes with higher weights (C₃₁, C₄₁). This suggests that although the remediation of rural black and odorous water has received a positive response, the water that have been remediated still face significant pressure and have limited benefits. Among them, the remediation effect of 10cases was rated as "Effective," while 1case was rated as "Passing." In the Pressure dimension, factors such as "high population load in the water area," "damage to sewage interception and pipe networks," and "residual black and odorous sludge," as well as in the Response dimension, "the investment in water body remediation is relatively high" and "insufficient implementation of operation and maintenance management" were the main adverse influencing factors of the remediation effect.
