A kind of secondary medicine system of water factory
This utility model is related to water treatment field, the secondary medicine system of specifically a kind of water factory.
Using the water factory of conventional drinking water treatment technique, filter is to ensure that the water turbidity that dispatches from the factory reaches country's life and drinks
The important process of water water standard, is also final step.It may be said that reducing water after filter turbidity is exactly that reduction is dispatched from the factory water turbidity.From water
From the point of view of factory's ruuning situation for many years, excessive in inflow, over loading in filter tank, and filtering velocity is too fast, during long-play, often goes out
The too high situation of existing water after filter turbidity.
But in drinking water quality specification, turbidity is an important indicator, is directly connected to the quality of water quality.After filter
In the case that water turbidity is too high, common treatment measures are mainly passed through to increase dosage, reduce sedimentation tank delivery turbidity, to control
Water after filter turbidity processed.
But, so undoubtedly increased adding of chemical feeding quantity, also just improve the cost of water process.
Utility model content
According to above-mentioned weak point, the purpose of this utility model is to provide a kind of secondary medicine system of water factory, thus reducing
Adding of chemical feeding quantity, can guarantee that delivery turbidity simultaneously again.
For achieving the above object, the technical solution of the utility model is：A kind of secondary medicine system of water factory, it include by
Reservoir, one-level pump house, sedimentation tank, filter tank, clear water reserviors and the repumping house being sequentially connected according to water (flow) direction, in described sedimentation tank
Front dosing toss area and front chlorination toss area are respectively equipped with inlet pipeline, secondary adding is provided with the outlet pipeline in described filter tank
Chlorine toss area, is respectively equipped with online transmissometer in the position of described sedimentation tank water side and the position of filter tank water side, in precipitation
Pipeline between pond and filter tank is provided with interim dosing toss area near the position of sedimentation tank.
Preferably：The water inlet end in described filter tank is provided with agitator.Medicine and impurities in water can be accelerated by agitator
Mixing, promote coagulation, improve impurity flocculating effect, further strengthen filter effect, reduce delivery turbidity.
The beneficial effects of the utility model are：Interim chemical feeding points are provided with the outlet pipeline of sedimentation tank, are once adding
After medicine and chlorination, the data according to online transmissometer at two, is judged, suitably opens interim chemical feeding points and carries out secondary dosing, this
Sample in the case of ensureing delivery turbidity, well below first time chemical feeding quantity, also just say, is ensureing water quality by the amount of secondary dosing
Under the premise of reduce cost.By the system, the summation of dosing twice reduces 30-50% than an original chemical feeding quantity.
Fig. 1 is structural representation of the present utility model.
In figure, 1- reservoir；2- one-level pump house；3- sedimentation tank；4- filter tank；5- clear water reserviors；6- repumping house；The online turbidity of 7-
Instrument；8- agitator；9- interim dosing toss area；Dosing and chlorination before A-；Bis- chlorinations of B-.
With reference to specific embodiment, this utility model is described further.
The secondary medicine system of a kind of water factory as shown in Figure 1, it includes the reservoir 1, being sequentially connected according to water (flow) direction
Level pump house 2, sedimentation tank 3, filter tank 4, clear water reserviors 5 and repumping house 6, dosing before being respectively equipped with the inlet pipeline of sedimentation tank 3
Toss area and front chlorination toss area, are provided with secondary chlorination toss area on the outlet pipeline in filter tank 4, in sedimentation tank 3 water side
The position of position and filter tank 4 water side is respectively equipped with online transmissometer 7, and the pipeline between sedimentation tank 3 and filter tank 4 is near precipitation
The position in pond is provided with interim dosing toss area 9.Wherein, the water inlet end in filter tank 4 is provided with agitator 8.
During use, normally carry out a dosing, chlorination and secondary chlorination, open the agitator 8 of filter tank 4 water inlet end.Fortune
After row a period of time, the data of the online transmissometer 7 according to sedimentation tank 3, open interim grug feeding jar 9 a period of time, then reduce
The dosage of dosing, and the data according to two online transmissometers 7, adjust the throwing of a dosing and secondary dosing in good time
