Problems solved by technology

Most of the existing sewage plants directly use several groups of cylindrical membranes with semi-permeable membranes to filter sewage. Due to the high concentration of sewage, the filtration pressure of the semi-permeable membranes in the cylinder is increased, and the maintenance of the semi-permeable membranes is shortened. cycle, which increases the cost of use

Abstract

The invention discloses sewage plant serial water treatment equipment with a reverse osmosis function. The sewage plant serial water treatment equipment comprises a primary filter pipe and a plurality of secondary filter pipes stacked in rows, the tail ends of the plurality of secondary filter pipes are provided with a circulation group used for enabling filtered concentrated liquid to flow back to the front ends of the secondary filter pipes, and the interior of the primary filter pipe is connected with a plurality of filter membrane groups end to end; and each filter membrane group is formed by butting a main coil pipe and a filter membrane pipe, a permeable membrane with a roll-shaped structure is sleeved in each secondary filter pipe, a water collecting pipe is adhered to one long side of the permeable membrane, a water inlet net is arranged on the middle layer of the permeable membrane, and a semi-permeable membrane sheet and a water producing net are sequentially arranged above and below the water inlet net. According to the invention, high-concentration sewage is circularly filtered by arranging the primary filter pipe and the spiral push type filter membrane group, large-particle macromolecules are intercepted, and the filtered clean liquid is guided and discharged into the plurality of secondary filter pipes to be circularly filtered for many times, so that clean water is obtained and collected for later use, and the equipment has the effects of practical value and use cost saving.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage plant serial water treatment equipment with reverse osmosis function. Background technique [0002] Reverse osmosis technology is to make water molecules flow through the semi-permeable membrane layer under the pressure greater than the osmotic pressure of the solution, but the impurities cannot pass through the semi-permeable membrane, so as to realize the separation of pure water and polluted impurities. Common semipermeable membranes include cellulose acetate membranes and polyamide membranes. The semi-permeable membrane can filter out heavy metals, organic matter, bacteria, residual chlorine, etc. in the water, and the reverse osmosis membrane does not separate dissolved oxygen, so the produced water is running water, which is especially suitable for water treatment needs of highly polluted and high hardness water sources. Most of the existing sewage plants...
