Abstract
The invention provides a water treatment film. The water treatment film comprises a film body, hydraulic pressure sensors, alarm apparatuses and a monitor upper computer, wherein the film body comprises a filter screen layer arranged on the upmost layer, and a coarse fiber filtering layer, a first hollow elastic layer, a polyvinylidene fluoride filtering layer, a second hollow elastic layer and a polyvinyl chloride filtering layer which are sequentially arranged under the filter screen layer; a group of hydraulic pressure sensors and the alarm apparatuses are arranged at the upper side of the filter screen layer, another group of hydraulic pressure sensors and alarm apparatuses are arranged at the lower side of the polyvinyl chloride filtering layer, and the hydraulic pressure sensors and the alarm apparatuses are electrically connected; the hydraulic pressure sensors are also connected with the monitor upper computer through wireless signals. The water treatment film has the beneficial effects that the impact resistance can be effectively improved, the hydraulic pressure can be monitored in real time, a remind for timely replacement of a filter screen can be made, and a water treatment effect can be guaranteed by arranging the polyvinylidene fluoride filtering layer and the polyvinyl chloride filtering layer in a double-layer splitting manner.
Description
technical field [0001] The invention belongs to the field of water treatment membranes, in particular to a water treatment membrane. Background technique [0002] Membrane separation technology is a new type of technology that uses a specially manufactured, selectively permeable semi-permeable membrane to separate liquid mixtures under the promotion of external forces. This kind of semi-permeable membrane is called separation membrane, and its membrane wall is full of small holes. In the process of separation, only external force is needed to push to obtain a higher separation level. Therefore, membrane separation technology is a very economical Energy technology. However, the impact resistance of the existing water treatment membrane is not strong, and it is difficult to replace the filter screen in time, which affects the efficiency of water treatment, and the single-layer fine filter screen is used for filtration, and the filtering effect is not good.
