Fig. 4 is a specific embodiment structural representation of the full siphon control of the utility model microbubble reaction gas floating filter.

The front is illustrated accompanying drawing 1, has not just repeated here.

Referring to Fig. 2, principle of the present utility model and prior art (referring to Fig. 1) are relatively, crucial difference is molten gas dispose procedure is advanceed to before the course of reaction, because dissolved air is a molecular state under the high pressure conditions, formed the microbubble of diameter about 50 microns behind the release of pressure, has fabulous dispersiveness, utilize the buoyancy of self to constitute fabulous contact conditions then, make the bubble suspended impurity, the triplicity of coagulant hydrolysis substance, form the carrier gas floccule body and rise to the water surface quickly, the principal character of Here it is this device (sees that Fig. 3 microbubble discharges the district, the mixed zone, reaction zone).

This device reaction is tight especially with combining of air flotation zone in addition, and where accomplish to distinguish is branch Jie line, has created best buoyance lift condition for the carrier gas floccule body, also is the most successful place of this device (seeing Fig. 3 reaction zone and air flotation zone).

Referring to Fig. 3, it has shown a basic embodiment of microbubble reaction gas floating filter in the utility model.It comprises that mainly dissolving 1, former water dashpot 2, molten gas discharge district 3, mixed zone 4, reaction zone 5, air flotation zone 6, clear water zone 7, air supporting outlet pipe 8, filtered water inlet pipe 9,

filtering area

10,11 and clear water house steward 12.

The air that dissolving 1 admission of air compressor is pressed into dissolves in the air that compresses in the water, receives molten gas by pipeline then and discharges district 3, produces microbubble at this.Owing to adopted hydrostatic release, microbubble is difficult for enlarging because of disturbance.Water from river, lake, reservoir etc. is at first delivered to former water dashpot 2, and the medicine in the dispensing kit is also thrown in former water dashpot 2 in addition.The former water that is added with medicine is delivered to mixed zone 4 by pipeline, discharges the microbubbles that district 3 produces at this and molten gas and mixes.Then, the former water that is added with medicine and microbubble arrives reaction zone 5, and in this district, reactions such as impurity, microorganism have produced floccule body in medicine and the water, and microbubble will adsorb these impurity and floccule body.Because the bubble ratio heavy and light,, become scum silica frost so the upper surface that impurity or floccule body float into air flotation zone, and overflow, flow into sewer, and remaining clear water falls into clear water zone 7 at air flotation zone 6 microbubble bands toward come-up.The clear water of clear water zone can be from 8 outputs of air supporting outlet pipe, and its turbidity of the clear water of clear water zone can reach 1 degree, meets drinking water standard.Clear water by the output of air supporting outlet pipe can enter filtering area from hand-hole 9, filtering area is selected rational filtering velocity, adopt coarse grain footpath double-layer filter material, first filter course 10 uses anthracite, it is 08～18mm) that particle diameter adopts 25～3mm(routine, second filter course 11 uses particles such as quartz, and particle diameter is that 1～12mm(routine is 05～12mm).The particle diameter of two filter courses is big than routine all, and its hole is also just big.

In order to guarantee the reliable process operation, easy to operate, reduce cost, we have adopted the control device of full siphon.

As everyone knows, the siphon filter that using so far appears in the sixties is many lattice (more than 6 lattice) combined running, and it also has been subjected to the landform restriction, and the filter tank water surface must be higher than the sewer water surface more than 6 meters, otherwise unconditional the use.

This device has been broken through above two conditions, does not need the combination of many lattice, carries out single lattice operation, not limited by landform, also can the trouble-free operation (see figure 4) under less than 6 meters height.

This device utilizes siphon principle to set up a vacuum system, can realize full siphon control.

All pipelines that need control all adopt the siphon form, are tied with a control valve and vacuum system, and when the vacuum control valve is opened, vacuum forms, and siphonage promptly produces.Otherwise open siphon destructive valve and connect atmosphere, siphonal siphonage is just destroyed, and reaches the effect of cutting off current.

See Fig. 4 for details, it is to have increased full siphon control device (each parts among Fig. 3 all do not draw) on the basis of Fig. 3 microbubble reaction gas floating filter.Full siphon control device is mainly used in supply and the discharging that clear water behind the controlled filter is gone into pond, recoil water.It mainly comprises vavuum pump 18, vacuum tank 19 and vacuum control pipe 20.By the clear water of clear water zone output after air supporting outlet pipe 8 is delivered to dashpot 13 more after filtration water inlet pipe 14 send into filtering area.Clear water siphon pipe 15 and vacuum control valve 23 and air admission valve 24 controls enter feelings pond 16 by the clear water of filtering area output.After filtering area had been grown service time, hole can get clogged, and at this moment needs to recoil.Providing of recoil siphon pipe 28 and vacuum control valve 21 and air admission valve 22 control recoil water, recoil water enters filtering

area

11,10 through recoil pump 17 recoils, is discharged by recoil discharge siphon 27 at last and flows into sewer.The through and off of vacuum control valve 25 and air admission valve 26 control recoil discharge siphon 27.

This device characteristic is reaction tank, flotation tank and the rapid filter three (see figure 1) that organically combines, and compares with other conventional structures and similar structures, has following significant advantage.

(1) the little efficient of volume province with high investment.

The general treatment process of its volume ratio is little more than one times, processes the water yield for every square metre and reaches 150 cubic metres/day, surpasses more than the general quilt, and the total residence time less than 40 minutes was below half of general technology, and reduced investment is a corollary.

(2) effluent characteristics is good.

The effluent characteristics of processing through this device is in the clear ahead status in the similar process unit at home and abroad, water can surpass drinking water standard (turbidity 1 degree following) before the filter, after the filter below 03 degree (national standard 3 is spent) and removal organic matter and heavy metal had preferably effect.
