36、所需要的水量;淘米水、煮过面条的水,用来洗碗筷,去油又节水;养鱼的水浇花,能促进花木生长。,清洗餐具要讲究方法有些餐具油污很多,可用一张卫生纸擦拭干净,再洗时就方便多了,这样不但节约了用水,也省了洗涤剂。另外,餐具最好放到盆里洗,不要直接用水龙头洗。,科学使用洗衣机洗衣机洗少量衣服时,水位不要定得太高。衣服太少不洗,等多了以后集中起来洗,也是省水的办法。如果将漂洗的水留下来做下一批衣服洗涤水用,小件、小量衣物提倡手洗,可节约大量的水。,e7d195523061f1c0deeec63e560781,e7d195523061f1c0deeec63e560781cfd59afb0ea006f2a87
