项目摘要

A deterioration of river and sea water environments is caused by various factors, including an influx of drainage contains washing detergents. Alternative washing agents are expected to be developed in order to improve those water environments. Several selected waters such as tap water, ion exchanged water and electrolyzed water (strong alkaline water and acid water) supplemented with SDS (0.1 - 0.3g/100ml) or polymer builder, anionic polyvinyl alcohol, (S-PVA 0.005g/100ml) were experimented to enhance a detergency of water itself.Apparent effects were recognized listed as follows :1) Research of the consumer's behavior of home laundryWe investigated consumers behavior of home laundry, for example, washing cycle, washing times, using detergents, washing water volume, etc., so we recognized that the washing action of consumer doesn't become action in order to defend water environment.2) Detergency of each washing waterThe results indicated that there was an apparent synergy of alkaline water with surfactants. Higher detergency was recorded when SDS was added to alkaline water and it showed clear correlation between the amount of SDS and the detergency. It was also cleared that apparent effectiveness appeared with less amount of SDS. Nonionic surfactants used in alkaline water also resulted higher effect. S-PVA indicated the best effect when it was used in alkaline water, and it had almost the same removal effect with surfactants when its concentration was 0.005g/100ml.3) A pollution rate of washing waterAdding SDS (0.2g/100ml) into tap water was also effective as indicated by COD which showed 29.4mg/l with SDS and 19.7mg/l without it. Therefore, it is concluded that the detergency of water itself can be enhanced by adding SDS into washing water, and using those enhanced water as an alternate of detergents is recommended to improve a river.

河流和海水环境的恶化是由各种因素造成的，包括含有洗涤剂的排水系统的流入。预计将开发替代洗涤剂，以改善这些水环境。选择自来水、离子交换水和电解水(强碱性水和酸性水)中添加十二烷基硫酸钠(0.1-0.3g/100ml)或聚合物助剂阴离子聚乙烯醇(S-PVA0.005g/100ml)等几种水，对提高水本身的去污力进行了实验。研究发现：1)消费者家庭洗衣行为的研究我们调查了消费者对家庭洗衣的洗涤周期、洗涤次数、使用洗涤剂、洗涤水量等行为。因此，我们认识到，消费者的洗涤行为并不是为了保护水环境而采取的行动。2)每种洗涤水的去污性。结果表明，碱性水与表面活性剂存在明显的协同作用。在碱性水中加入十二烷基硫酸钠时，洗涤剂的去污力较高，且十二烷基硫酸钠的用量与去污力之间存在明显的相关性。SDS用量较少时，疗效明显。在碱性水中使用非离子表面活性剂也有较高的效果。S-PVA在碱性水中的去除效果最好，当其浓度为0.005g/100ml时，其去除效果与表面活性剂相当。3)向自来水中投加十二烷基硫酸钠(0.2g/100ml)对洗涤水的污染率也是有效的，其COD值分别为29.4 mg/L和19.7 mg/L。因此，在洗涤水中加入十二烷基硫酸钠可以提高水本身的去污力，建议用这些强化水作为洗涤剂的替代品来改善河流。
