Description
Technical field
The present invention relates to a kind of back-flushing reclaiming system, belong to water treatment field.
Background technology
Automatic water-purifying device for ensureing that effluent quality reaches instructions for use, must carry out backwash frequently in running, and the water after generally backwashed enters irrigation canals and ditches, no longer reuses.In order to saving water resource cuts the waste, propose backwashing water recycling, this meets the large principles and policies of the energy-saving and emission-reduction that country proposes.Backwash recycle-water contains a large amount of flocculates, turbidity is very high, sedimentation basin (concrete pond) is adopted to carry out flocculation sediment, then sludge condensation is carried out by the sludge concentration tank of steel structure, by plunger displacement pump, thickened sludge is squeezed into filter press, by mud-water separation, water enters sedimentation basin by pipeline, and mud is pressed into mud cake by filter press and transports outward process.In existing drinking water treatment systems, backwashing water is along with having drained in waste effluent flume, and one is waste water resource, and two is cause certain pollution to environment.
Practical content
The object of this invention is to provide the back-flushing reclaiming system that a kind of automaticity is high, the above-mentioned defect of prior art can be solved preferably, not only saving water resource, cut the waste and environmental protection, to reach the object that water dirt is separated.
In order to achieve the above object, a kind of back-flushing reclaiming system designed by the present invention, comprise the equipment connected successively by pipeline, equipment on described pipeline is sequentially bag filter, first motor-driven valve, first check valve, first elevator pump, second check valve, flow-sensint unit, second motor-driven valve, back-flushing settling apparatus, 3rd motor-driven valve, second elevator pump, 3rd check valve, clear water tanks, 4th motor-driven valve, 4th check valve, described first elevator pump and the second check valve, flow-sensint unit, be connected between the first check valve and back-flushing settling apparatus after pipeline after second motor-driven valve series connection carries out parallel connection, described bag filter is provided with the first water quality sensor, described back-flushing settling apparatus is provided with liquid level sensor, described clear water tanks is provided with the second water quality sensor, and after clear water tanks is connected to the first check valve by pipeline, pipeline is provided with four motor-driven valves, the 4th check valve.
The principle of above-mentioned back-flushing reclaiming system is as follows: first from the water of water tower after being provided with the filtration of the bag filter of water quality sensor, water quality sensor detects water quality, when testing result is consistent with preset value, sensor output switching signal, connect the motor-driven valve group at bag filter place, current are made to convert recoil state to, then the first motor-driven valve and the second motor-driven valve are opened, bag filter back-flushing is to direction of arrow flowing in figure, enter back-flushing settling apparatus, because there is hydraulic pressure at bag filter place, flow-sensint unit receives the flow information of water of bag filter back-flushing, no-output action, back-flushing settling apparatus is provided with liquid level sensor, and when water level reaches the water level of setting, level sensor outputs signal, and turns off the motor-driven valve group of filtering package place, stops back-flushing entering sedimentation basin.Back-flushing settling apparatus is provided with time controller, water be extracted into the highest liquid level time, automatically stop pumping, then triggered time controller starts timing, to arrive after certain hour (this time enough allow water sedimentation), start the second elevator pump and water is evacuated to clear water tanks.Clear water tanks is also provided with water quality sensor, and when sensor reaches the numerical value of setting, water quality sensor outputs signal, and opens the 4th motor-driven valve, starts the first elevator pump simultaneously, the back-flushing in clear water tanks is promoted to sedimentation basin, realize the reuse of back-flushing.
As preferably, described back-flushing settling apparatus is back-flushing settling tank or back-flushing sedimentation basin.
As preferably another, be provided with for precipitating sludge outlet bottom described back-flushing settling apparatus, precipitating sludge outlet is connected with sludge filter press.
It is high that above-mentioned back-flushing reclaiming system has automaticity, improves efficiency; And simple and easy to do, realize with low cost, greatly reduce the fault rate of back-flushing system simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below by embodiment, the invention will be further described by reference to the accompanying drawings.
As shown in Figure 1, a kind of back-flushing reclaiming system, comprise the equipment connected successively by pipeline, equipment on described pipeline is sequentially bag filter 1, first motor-driven valve 2, first check valve 3, first elevator pump 4, second check valve 5, flow-sensint unit 6, second motor-driven valve 7, back-flushing settling apparatus 8, 3rd motor-driven valve 9, second elevator pump 10, 3rd check valve 11, clear water tanks 12, 4th motor-driven valve 13, 4th check valve 14, described first elevator pump and the second check valve, flow-sensint unit, be connected between the first check valve and back-flushing settling apparatus after pipeline after second motor-driven valve series connection carries out parallel connection, described bag filter is provided with the first water quality sensor 15, described back-flushing settling apparatus is provided with liquid level sensor 16, described clear water tanks is provided with the second water quality sensor 17, and after clear water tanks is connected to the first check valve by pipeline, pipeline is provided with the 4th motor-driven valve, the 4th check valve, described back-flushing settling apparatus is provided with time controller 18.Described back-flushing settling apparatus is back-flushing settling tank or back-flushing sedimentation basin.Be provided with for precipitating sludge outlet 19 bottom described back-flushing settling apparatus, precipitating sludge outlet is connected with sludge filter press 20.
