摘要
本文论述了以废旧塑料为主的白色垃圾对人类生存环境造成的危害性,同时研究了以废聚苯乙烯泡沫塑料为原料,合成水溶性高分子聚合物-聚苯乙烯磺酸钠(NaPSS),对三种工业废水的混凝沉降,试验表明:NaPSS能提高沉降速度30%～60%,助凝性能接近PAM,在一定程度上可以替代PAM。经过可行性评估和成本效益分析,此综合利用技术是可行的,并具有较好的社会、环境效益和一定的经济效益,为解决白色污染及废旧塑料的综合利用开辟了新途径。
In this paper, the pollution of waste plastics to the environment was reviewed, at the same time, sulfonic sodium polystyrene(NaPSS),a water soluble macromolecule polymer, was made of waste styrofoam under suitable conditions. Flocculation of NaPSS was very well ,it could increase sedimentation rate about 30%~60%, showed by the coagulating experiments on three different industrial wastewater. It could be substituted for the existing product PAM. After feasibility evaluation and cost benefit analysis, the comprehensive utilizable technology was feasible, and it had societal benefit, environmental benefit and some economic benefit. It also provided a new approach for the white pollution and waste plastics.
