High-efficient energy-saving reverse osmosis filtration system

Abstract

The invention provides a high-efficient energy-saving reverse osmosis filtration system. The high-efficient energy-saving reverse osmosis filtration system is characterized by comprising a secondary filtration system and a plurality of primary filtration systems, wherein a plurality of sand filters, a plurality of protectors and a plurality of groups of reverse osmosis filters are arranged in any one of the primary filtration system; a plurality of protectors and a plurality of osmosis filters are arranged in the secondary filtration systems. According to the high-efficient energy-saving reverse osmosis filtration system, an ion exchanger of an original system and the sand filter tank of a third set of equipment are eliminated, so that operation and maintenance processes of the ion exchanger are omitted, cleaning and maintenance processes of the sand filter tank are also omitted, and the water and electricity consumption is reduced; meanwhile, the repairing capitals of the equipment and the human input are eliminated, the sewage treatment quantity meets the production requirement, and the pass percent of water quality in the process is greatly improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a high-efficiency and energy-saving reverse osmosis filtration system. Background technique [0002] The original chemical sewage treatment mainly adopts an equipment system consisting of three operating procedures, namely mechanical filtration-reverse osmosis filtration-ion exchange, to reduce the particulate impurities and conductivity of sewage, and the treated sewage can be recycled. Among them, mechanical filtration includes sand filter tank mechanical filtration and security filtration, which mainly uses the filler installed in the filter to intercept and remove suspended particles and colloidal impurities in water. Reverse osmosis filtration mainly makes the solution pass through the reverse osmosis membrane through the pressure difference, thereby intercepting various inorganic ions, colloidal substances and macromolecular solutes in the water. Ion exchange mainl...

Problems solved by technology

In particular, ion exchangers are prone to corrosion during actual use, requiring frequent replacement of equipment components, high maintenance costs, and large labor investment; at the same time, the equipment consumes high energy and the process operation is complicated

In this case, the use of ion exchangers not only increases the cost, but also has a great negative impact on water quality
