Abstract
The utility model discloses reverse osmosis treatment equipment with a three-layer quartz sand filter, comprising the quartz sand filter connected with pretreated water intake, wherein the quartz sand filter is connected to an activated carbon filter, the activated carbon filter is connected to a reverse osmosis treatment device, the quartz sand filter is sequentially provided with a first quartz sand layer, a second quartz sand layer and a third quartz sand layer from top to bottom, the grain size of the quartz sand in the first quartz sand layer is smaller than the grain size of the quartz sand in the second quartz sand layer, and the grain size of the quartz sand in the second quartz sand layer is smaller than the grain size of the quartz sand in the third quartz sand layer. According to the reverse osmosis treatment equipment with the three-layer quartz sand filter, the single-layer quartz sand filling layer in the prior art is replaced by the filter material filling layer employing three more reasonable and more delicate layers of quartz sand with different specifications, so that the quality of pretreated effluent water is guaranteed, the requirement on reverse osmosis water intake is met, and the reverse osmosis recovery rate and the service life of a reverse osmosis membrane are accordingly improved.
Description
Technical field
The utility model relates to the Reverse Osmosis Water Treatment Technology field, especially a kind of reverse osmosis treatment equipment with quartz filter of the quartz sand replacement individual layer quartz sand packing course that utilizes three layers of different size.
Background technology
In known Reverse Osmosis Water Treatment Technology field, in order to improve water supply conditions, make it to reach the water inlet requirement of reverse osmosis system, usually need to carry out the pre-treatment design for different water quality, modal is to form pretreatment system by quartz filter, activated charcoal filter, Scale inhibitors chemicals dosing plant and cartridge filter.Reverse osmosis efficiency and life-span and former water pretreatment effect are closely related, pretreated purpose be exactly to drop to water inlet to the pollution of film, fouling, damage etc. minimum, thereby make system's water production rate, ratio of desalinization, the rate of recovery and running cost optimization.Therefore, good pre-treatment is very important to the long-term safety operation of reverse osmosis unit.
The existing quartz filter that utilizes individual layer filtrate packing course, its effluent quality is poor, and filtration cycle is short, so that reverse osmosis efficiency is low, easily so that reverse osmosis unit pollution, fouling and damage.
The utility model content
The technical problems to be solved in the utility model is: a kind of reverse osmosis treatment equipment with three layers of quartz filter is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of reverse osmosis treatment equipment with three layers of quartz filter, comprise the quartz filter that links to each other with the pre-treatment water inlet, described quartz filter is connected to activated charcoal filter, described activated charcoal filter is connected to reverse osmosis treatment device, described quartz filter is provided with the first quartz sand layer from top to bottom successively, the second quartz sand layer and the 3rd quartz sand layer, and the particle diameter of the quartz sand in described the first quartz sand layer is less than the particle diameter of the quartz sand in the second quartz sand layer, and the particle diameter of the quartz sand in described the second quartz sand layer is less than the particle diameter of the quartz sand in the 3rd quartz sand layer.
Further, as a kind of concrete form, the first quartz sand layer described in the utility model has the quartz sand that particle diameter is 0.3-0.5mm, and described the second quartz sand layer has the quartz sand that particle diameter is 0.5-1.0mm, and described the 3rd quartz sand layer has the quartz sand that particle diameter is 1.0-2.0mm.
Further, as a kind of concrete form, the first quartz sand layer described in the utility model, the second quartz sand layer and the 3rd quartz sand layer three's floor height ratio is 2:1:1.
Further, in order to improve pretreated effect, also has the quartz sand layer that particle diameter is 1.0-2.0mm in the activated charcoal filter described in the utility model.
The beneficial effects of the utility model are: the utility model replaces existing individual layer quartz sand packing course mode to guarantee the pre-treatment effluent quality by utilizing more reasonable three layers of exquisiter different size quartz sand to carry out the filtrate packing course, satisfying the feed water by reverse osmosis requirement, thereby improve the reverse osmosis system rate of recovery and reverse osmosis membrane work-ing life.
