    Abstract: Waste water from bean-curd plant is purified by making the pH of crude waste liquid newtral and passing the hot waste water through HR-type reverse osmosis membrane before cooling. The waste crude liquid of bean-curd is pretreated by removing large-size solid particles, which are filterd through gauze. The above purification process can operate continuously and require lower energy. The process shows an excellent purifying effect for bean-curd waste water.

    Abstract translation: 豆腐植物的废水通过使粗废液pH值上升,并在冷却前将热废水通过HR型反渗透膜进行纯化。 通过去除通过纱布过滤的大尺寸固体颗粒预处理豆腐废液。 上述净化过程可以连续工作,需要更低的能量。 该方法对豆腐废水具有极好的净化效果。
