Reverse osmosis membrane secondary utilization apparatus

Abstract

The invention discloses a reverse osmosis membrane secondary utilization apparatus. A water entering chemical charging part comprises a water entering cavity and a floating chemical amount adjusting apparatus which is arranged in the water entering cavity in a sliding manner, a flocculating part and a mixing part are installed in a joint manner, a precipitating tank and the flocculating part are arranged in a joint manner, a hyper-filtration part and the precipitating tank are connected in a joint manner, a primary reverse osmosis membrane frame and a secondary reverse osmosis membrane frame are respectively provided with primary reverse osmosis membrane shells and secondary reverse osmosis membrane shells which are same in number and are distributed in an array manner, and the reverse osmosis membrane shells on the primary reverse osmosis membrane frame and the secondary reverse osmosis membrane frame are equidistantly distributed in a staggering manner. The reverse osmosis membrane replaced under a working condition with a relatively high filtering requirement can be used at a primary reverse osmosis section and a secondary reverse osmosis section under the working condition withlow filtering requirements, the exchange of the primary reverse osmosis membrane shell and the secondary reverse osmosis membrane shell can be conveniently realized after the primary reverse osmosissection is blocked by sewage, the work can be continued, and the utilization rate of the reverse osmosis membrane can be improved.

Description

technical field [0001] The invention belongs to the field of automation equipment, in particular to a reverse osmosis membrane secondary utilization device. Background technique [0002] At present, reverse osmosis technology has been widely used in water treatment technology, but in some occasions with high filtration requirements, the used reverse osmosis membrane needs to be further cleaned before it can be used, or it can be discarded directly after failing to meet the filtration requirements, and the use efficiency is not high. , and it is troublesome to replace and install the reverse osmosis membrane shell on the filter equipment. Contents of the invention [0003] The object of the present invention is to provide a reverse osmosis membrane secondary utilization device to solve the problems raised in the above-mentioned background technology. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A reverse ...
