As shown in Figure 2, be the structure iron of cleaner 104 among the present invention.The internal structure of cleaner 104 comprises first reaction chamber 1041, second reaction chamber 1042, mixing section 1043, separate chamber 1044, nozzle 1045, filtrate 1046, bucket 1047, water inlet pipe 1048 and shell 1049; First reaction chamber 1041, second reaction chamber 1042, mixing section 1043, separate chamber 1044, nozzle 1045, filtrate 1046, bucket 1047 are positioned at the inside of shell 1049; The bottom of shell 1049 is taper, and bucket 1047 is arranged on the bottom of shell 1049, and shell 1049 upper openings also are provided with loam cake 109; First reaction chamber 1041 is a flared structure with mixing section 1043, and the less end of bore is together interconnection, and mixing section 1043 is positioned at first reaction chamber, 1041 bottoms; Second reaction chamber 1042 is columnar structured, and opening one end is buckled in the top of first reaction chamber 1041; The space outerpace of second reaction chamber 1042 is separate chamber 1044; Filtrate 1046 is arranged on 1044 tops, separate chamber; Nozzle 1045 is arranged on the end of water inlet pipe 1048, and is positioned at mixing section 1043 inside, and the other end of water inlet pipe 1048 connects the water outlet of waste water pump 103.
Cleaner 104 is mainly based on principle and other physics and the chemism work of condensing with oxidation in the chemical reduction; Its inside is divided into 5 districts; Be respectively high-speed eddy reaction zone, the slow reaction zone of gradual change, suspension clarification settling region, powerful suction zone and mud enrichment region, wherein, the internal space of mixing section 1043 forms the high-speed eddy reaction zone; The internal space of first reaction chamber 1041 forms the slow reaction zone of gradual change; The internal space of second reaction chamber 1042 forms the clarification settling region that suspends, and the space of separate chamber 1044 forms powerful suction zone, and the internal space of bucket 1047 forms the mud enrichment region.
As shown in Figure 3, be to purify the schema that fluoride waste is handled among the present invention.Elaborate in the face of purifying method of the present invention down.
1, fluoride waste is squeezed into wastewater disposal basin 101 earlier, carry out preliminary sedimentation;
2, open waste water pump 103 and dosing valve 111, the upper clear supernate that deposition in the wastewater disposal basin 101 is good is squeezed into cleaner 104 through waste water pump 103;
Add water inlet pipe 1048 entering cleaners 104 inside of the waste water of an amount of medicament by cleaner 104 bottoms, through nozzle 1045 ejections, nozzle 1045 tops are the mixing section 1043 and first reaction chamber 1041.Nozzle 1045 is formed an ejector with mixing section 1043; The high velocity jet of nozzle 1045 ejections contains the pond conical lower portion water inspiration mixing section 1043 interior and water inlet mixing of a large amount of flocs units; After first reaction chamber, 1041 hydraucones overflow, get in second reaction chamber 1042.First reaction chamber and second reaction chamber have constituted a suspended substance district, and 1042 water outlets of second reaction chamber get into separate chamber 1044, and supernatant penetrates filtrate 1046 overflows and discharges; Various oxyhydroxide form slime layer, and throw out sedimentation under the self gravitation effect is constantly arranged, and form sludge blanket at bucket 1047.Filtrate 1046 is selected light filter material for use, and its density is overflowed to prevent filtrate 1046 so cleaner 104 tops need be provided with loam cake 109 less than water.
In this process, add medicines such as Ca (OH) 2, oxygenant and flocculation agent through dosing pipe 110, mix through jet, Ca (OH) 2, oxygenant and flocculation agent and waste water thorough mixing add NaOH adjustment pH value to neutral, adjust to usually between the pH value 6～8.Flocculation agent can be one or more in the high-performance flocculation agents such as white lake, poly-aluminum ferric chloride sulfate, Poly aluminum Chloride (PAC) or poly-epoxy succinic acid, and inorganic flocculating agent has Tai-Ace S 150, iron trichloride, Poly aluminum Chloride (PAC), bodied ferric sulfate etc. available.
3, in cleaner 104, carrying out detoxification purifies;
It is exactly with the F in the water that detoxification purifies
-With chromium ion and some other heavy metal ion and water sepn.Cleaner 104 combines jet mixing, reaction, clarification, sloping plate deposition and filtrate 1046 filtration procedurees.
4, the mud of bucket 1047 is squeezed into sludge sump 106 through shore pipe 110, further can squeeze into and carry out press filtration in the pressure filter, and filter cake is collected pack;
Behind the cleaner 104 running certain hours, need timely spoil disposal, spoil disposal 1-2 consuming time minute.
5, activated carbon filtration;
The gac of current behind the detoxification in filtrate 1046 done further absorption removal with toxic substance in the water and throw out.
6, draining up to standard.
Clear water after up to standard extracts through fresh water pump 107 and is discharged in the clean water basin 105, if the clear water overflow takes place, then clear water is discharged in the clean water basin 105 through upflow tube 108.
When cleaner stops, closing dosing valve 111 and water intaking valve earlier, close down waste water pump 103, fresh water pump 107 again.During cleaner 104 operation, delivery turbidity needs back flushing during greater than 3mgk; The sample of will often getting in service is observed change of water quality, in time adjusts dosage; After waste water pump 103 abundant stirrings, impel water to gather into thin mud layer, rely on action of gravity to slide back the body refuse suspended layer, sink to bucket 1047 then, remaining small flco is filtered by filtrate 1046.As find that water quality degenerates, and should take corresponding measure, amount when intaking as reducing increases or reduces dose, gets rid of mud, carries out back flushing etc.
