日本大阪府最近正式采用了大阪大学环保工程教授开发的一种污水处理新装置。这种装置除了用以净化污水,又可用来养殖水产动植物,因此定名为污水处理养殖机。机身为4层相重叠,长8m 的25×25cm 之水路,附调整槽和蔬菜栽培槽。每日可处理1000m~3的污水(生化需氧量约为20—60mg/L),在水路中布置波状塑胶接触板和带状的接触材料以黏着水中所繁殖的水藻。当污水流经蔬菜栽培槽,并从最上层水路流经调整槽时,流水中养殖吴郭
Osaka Prefecture, Japan recently formally adopted a new sewage treatment plant developed by Professor of Environmental Engineering at Osaka University. This device is not only used to purify the sewage, but also can be used to culture aquatic animals and plants, so named for the sewage treatment aquaculture machine. The fuselage is 4 layers of overlapping, long 8m 25 × 25cm of the waterway, with adjustment trough and vegetable cultivation tank. Daily treatment of sewage of 1000m ~ 3 (biochemical oxygen demand of about 20-60mg / L), arranged in the waterway corrugated plastic contact plate and ribbon contact material to stick in the water breeding algae. When the sewage flows through the vegetable cultivation tank and flows through the adjustment tank from the uppermost waterway,
