Detailed description of the invention
For the water treatment facilities technical scheme of above-mentioned offer, now lift a preferred embodiment and combine diagram and be specifically described.Water treatment facilities of the present utility model, mainly includes defecator, controls the control device that defecator works.Wherein.
Defecator, referring to Fig. 1 and Fig. 2, defecator is two-stage, and first level filtering device 1 and two-stage filter 2 are provided with overflow launder 3 between first level filtering device and two-stage filter.Tank 11 that first level filtering device 1 includes water storage and the grade one filter 12 being arranged in tank.In FIG, being flat bottom tank, can be the bottom of cone bottom tank, conical lower section be conducive to the contamination precipitations such as the granule in tank to assemble.Sidewall Height between tank and overflow launder is less than other Sidewall Height of water storage, thus forms overflow plate 13, when the water level in tank rises to overflow plate 13 height, is then flow in overflow launder 3 by overflow plate 13.Can also take to offer overfall on the sidewall between tank and overflow launder, make the superfluous water exceeding water level in tank flow to overflow launder from overfall.The side of tank 11 is provided with water inlet pipe, water inlet pipe is provided with dosing pump 14.The water inlet port of water inlet pipe connects with water head site.The water of water head site is provided in the tank to first level filtering device by water inlet pipe.
Tank 21 that two-stage filter 2 includes water storage and the secondary filter 22 being arranged in tank.In FIG, being flat bottom tank, can be the bottom of cone bottom tank, conical lower section be conducive to the contamination precipitations such as the granule in tank to assemble.Sidewall Height between tank and overflow launder is less than other Sidewall Height of water storage, thus forms overflow plate 23, when the water level in tank rises to overflow plate 23 height, is then flow in overflow launder 3 by overflow plate 23.Can also take to offer overfall on the sidewall between tank and overflow launder, make the superfluous water exceeding water level in tank flow to overflow launder from overfall.The overflow plate of two-stage filter or the height of overfall are all high than the height of the overflow plate of first level filtering device or overfall, and its purpose prevents when breaking down, and the water in overflow launder and first level filtering device pours in down a chimney in two-stage filter.
Grade one filter 12 and secondary filter 22 are respectively accurate filter, and secondary filter is higher than grade one filter filtering accuracy.The water level of the tank water level of first level filtering device and the tank of two-stage filter lays respectively at above grade one filter and secondary filter.
Grade one filter 12 is connected with the tank 21 of two-stage filter by pipeline, is provided with dosing pump 121 on the pipeline connected with grade one filter.Secondary filter 22 is connected with the sample introduction end water supply container of SPE-LC-MS test instrunment by pipeline, is provided with dosing pump 221 on the pipeline connected with secondary filter.
Bottom the tank of first level filtering device and two-stage filter and the bottom of overflow launder is respectively arranged with drainage arrangement 4, i.e. bottom the tank of first level filtering device and two-stage filter and the bottom of overflow launder offers discharge outlet respectively, this discharge outlet is connected with external environment condition by drainage pipeline, the water that external environment discharge is unnecessary, being respectively arranged with electromagnetic valve (15,24) on drainage pipeline bottom the tank of first level filtering device and two-stage filter, the drainage pipeline of overflow launder is in normally open.
Controlling device 5, be positioned at first level filtering device side, it controls each dosing pump in water treatment facilities and the opening and closing of electromagnetic valve.
The another kind of embodiment of this utility model water treatment facilities, referring to Fig. 3, on first level filtering device, the pipeline being connected between dosing pump 121 and grade one filter is provided with scopometer 16.The pipeline that the outfan of dosing pump 121 connects is respectively arranged with the pipeline 17 that the sample introduction end water supply container with SPE-LC-MS test instrunment directly connects and the pipeline 18 connected with the tank of two-stage filter, pipeline 17 and pipeline 18 are respectively arranged with electromagnetic valve (171,181).In Fig. 1 embodiment, water head site water is pumped into by dosing pump in the tank of first level filtering device and stores, and enters in the tank in two-stage filter after grade one filter filters and store；Filter in the sample introduction end water supply container entering test instrunment via secondary filter again.Owing to each defecator action controls by controlling device, when needs detect, each defecator action can be started by control device and carry out filter feeding detection.But the embodiment of Fig. 1 there is also certain drawback, after the water quality after first level filtering device filters reaches requirement, more then belonging to idle operation through secondary filter filtration, the use for no reason reducing secondary filter is the life-span, takes time and effort, and filters cost high.After branch flow pipe in increasing Fig. 2, after water quality after grade one filter filters reaches requirement, when scopometer is detected as qualified, the electromagnetic valve 171 then controlling device control pipeline 17 is opened, the closed electromagnetic valve of pipeline 18, directly the water through grade one filter filtration treatment is pumped in detecting instrument sample introduction end water supply container, eliminate secondary filter filtration treatment, save the operating cost that cascade filtration processes.When the water quality that scopometer detection grade one filter processes is the most up to standard, then the electromagnetic valve 181 controlling device control pipeline 18 is opened, and the electromagnetic valve 171 of pipeline 17 cuts out, and the water processing single filter carries out cascade filtration process.Use the Water treatment filtration mode of Fig. 2, can choose whether to need cascade filtration to process according to the result that single filter processes, reduce filtration treatment cost, also improve the service life of secondary filter.
After filtration treatment a period of time, the good secondary filter of grade one filter all can carry out filter flushing by backwash, improves filter filter efficiency and service life.
