废线路板跨区域回收系统模拟与环境影响评价

Simulation and Environmental Impact Assessment of InterregionalRecycling System for Waste Circuit Boards

针对废线路板在收集与处置过程中,各区域存在跨地区协调性弱、处置能力不匹配等问题,使用最小距离最大流(MDMF)模型对废线路板跨区域最优流动路径及流量进行模拟,并对优化结果进行环境影响评价。结果表明:随着废线路板产生量逐年增加,根据模拟优化的跨区域回收路径,拥有典型废线路板处理技术的地区,如广东、湖北等都能达到其最大产能,且该条件下环境影响程度较小。本研究为废线路板回收系统的区域协调规划提供了理论支撑。

Address to weak interregional coordination and mismatch of disposal capacity in various regions during the collection and disposal of waste circuit boards,the minimum distance maximum flow(MDMF)model was used to simulate the optimal flow path and flow of waste circuit boards across regions,and the environmental impact assessment of the optimization results was carried out.The results show that as the amount of waste printed circuit board generation increases year by year,according to the simulated optimized interregional recycling path,areas with typical waste printed circuit board treatment technology,such as Guangdong and Hubei,can reach their maximum production capacity,and the environmental impact under this condition is small.This study provides theoretical support for the regional coordinated planning of waste printed circuit board recycling system.
