Fig. 1 is the synoptic diagram according to water treatment system of the present invention.Under action of gravity or by pump, be pumped into water treatment device 20 through piping 11 from buck such as the gray water sources 10 of generation bucks such as having a bath, clean, do washing or wash the dishes.Buck is after processed through water treatment device 20, the waste water that includes solid particulate matter etc. is discharged through pipelines 21 from water treatment device 20 below sidepieces, and be discharged in the water shoot 23 by the trap 22 of a water seal, enter into water treatment system to prevent vitiated air.Treated water flow in the treating water collection box 25 through water treatment device 20 bottom pipe 24.Treated water in treating water collection box 25 is pumped in the treating water bin 50 through piping 27 by pump 26, prepares to be used to wash lavatory etc.
The tangential inlet 32 of intake chamber 30 is designed so that the buck that enters is rotated motion, the rotatablely moving and produced centrifugal force of buck.This centrifugal force makes sepn process begin, and it rotates to intake chamber 30 outsides with heavy or big suspended particulate, thereby the buck that enters is divided into two parts.Include most of big and heavy total suspended solid thing and a small amount of buck of most of biological oxygen demand (BOD) and chemical oxygen demand (COD) (COD) and enter annular space 35, and needn't be by media bed 45 in the filter body 40, thereby reduced the dirt that is deposited on media bed 45, thereby significantly improved the filtration efficiency of filter body 40.Enter buck be rotated that part of length of the intake chamber 30 of motion therein should sufficiently long, have the competent time therein and be rotated motion so that enter buck, thereby make heavy or big particulate matter move to the outer side wall of intake chamber 30 fully and enter downwards in the annular space 35.Preferably shrink gradually the bottom of intake chamber 30, quickens to be rotated in place in the wastewater collection district of filter body 40 belows and enter tangential outlet 33 so that enter the buck of annular space 35.Tangential outlet 33 is arranged to make waste water to discharge with entering the identical sense of rotation rotation of buck, that is, make to enter buck and waste water all in a clockwise direction or be rotated counterclockwise.For waste water is not trapped in the intake chamber 30, tangentially export 33 its lowermost position that preferably are arranged on intake chamber.
The buck of having got rid of heavy or big particulate matter by rotation is transported to water guiding ring 41, enter filter body 40 inside by water guiding ring, buck infiltration subsequently is by media bed 45, and media bed 45 filtrations and/or absorb polluted matter also make the water of crossing through filtration treatment enter treating water collection box 25 through nozzle collector 47 discharge filter main bodys 40.Media bed 45 media types that adopted depend primarily on the pollutant kind that is comprised, and for example can be simple silica sand, garnet, pottery, plastics or gac etc.The flow of buck by filter body 40 is by the flow velocity decision of media bed unit surface.
In the common filtration procedure that flows downward, need to use a source of the gas to help the separately mud ball of medium, but water treatment system of the present invention does not need to use source of the gas, because it is not intended for use long-term online filtration.Therefore, water treatment system of the present invention is streamline filtration (edgefiltration) effectively, only has only a spot of depth filtration (depth filtration).
Water treatment system of the present invention also is provided with programmable logic controller 60, is used to control the operation of water treatment system.In the normal filtration operational process, buck is rotated in the strainer main body 40 and filters, and the water after the filtration is discharged in the treating water collection box 25.Be provided with the top surface cock 61 and the bottom surface cock 62 that are communicated with programmable logic controller 60 respectively in the treating water collection box 25.When the liquid level in the treating water collection box 25 reached top surface cock 61, top surface cock 61 was activated.Signal from top surface cock 61 passes through programmable logic controller 60 starting up pumps 26, and pump 26 is pumped into treating water bin 50 with treated water from treating water collection box 25, prepares to be used to wash lavatory etc.In case the liquid level in the treating water collection box 25 drops to bottom surface cock 62, bottom surface cock 62 is activated.Signal from bottom surface cock 62 stops pump 26 by programmable logic controller 60.Filter body 40 has been handled after a certain amount of buck, can the normal dirt of sediment-filled phase on media bed 45, and grey water handing efficient reduces gradually, therefore, need carry out backwash to media bed 45, to remove dirt.Counter records in programmable logic controller 60 has stopped and having started set point number to pump 26, is generally 20 times, and water treatment system enters backwash procedure.
As shown in Figure 1, can adopt one of two kinds of backwash mode to carry out to the backwash of filter body 40.In backwash mode 1, after the counter records in the programmable logic controller 60 has stopped to pump 26 and has started set point number, programmable logic controller 60 cuts out the magnetic valve 64 on the pipeline 27, open the magnetic valve 66 on the pipeline 65 that is communicated with pipeline 24 and pipeline 27, starting up pump 26 simultaneously upwards flows through media bed 45 thereby treated water in the treating water collection box 25 is pumped.Treated water upwards flows through media bed 45 with controllable rate, make media bed 45 medium can fully become flexible discharging captured contaminants, but be unlikely to make medium to be lost to annular backwash chute 43 or annular space 35.The backwash water that has pollutent flows into annular backwash chute 43 by the gap between annular backwash chute 43 and the water guiding ring 41, and the backwash overflow ducts 44 of flowing through is discharged by tangential outlet 33.The backwash water that has a pollutent also can be directly be overflowed from water guiding ring 41 and flow to annular space 35 and discharge through tangential outlet 33.
In backwash mode 2, adopt tap water that filter body is carried out backwash.After the counter records in the programmable logic controller 60 has stopped to pump 26 and has started set point number, ball valve 69 on the pipeline 68 that programmable logic controller 60 is opened with water source and pipeline 24 from the beginning are communicated with, thus make tap water upwards flow through media bed 45.Ball valve 69 control tap water upwards flow through media bed 45 with controllable rate, make that media bed 45 medium can fully become flexible to discharge captured contaminants, still are unlikely to make medium to be lost to annular backwash chute 43 or annular space 35.The backwash water that has pollutent flows into annular backwash chute 43 by the gap between annular backwash chute 43 and the water guiding ring 41, and the backwash overflow ducts 44 of flowing through is discharged by tangential outlet 33.The backwash water that has a pollutent also can be directly be overflowed from water guiding ring 41 and flow to annular space 35 and discharge through tangential outlet 33.
In backwash process, the medium in media bed 45 needs by loosening, needs to have a space so that medium can be by loosening on media bed.The backwash water flow velocity depends on the proportion of working medium, and sets backwash mode 1 or backwash mode 2 with this, thereby guarantees that medium can become flexible so that be cleaned fully, but is unlikely to medium is discharged in the waste water.
