Type integrated wastewater treatment equipment can be selected more than buried or ground according to actual conditions.
Brief description of the drawings
Fig. 1 is general structure schematic diagram of the present utility model；
Fig. 2 is the structural representation between the utility model coagulation reaction tank and sedimentation basin.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
Embodiment
Referring to Fig. 1, the utility model discloses a kind of industrial wastewater treatment device, it is included according to wastewater treatment process
Chromium reduction pond, coagulation reaction tank, sedimentation basin, intermediate pool, quartz filter and the clear water reserviors set gradually, chromium reduction pond,
Coagulation reaction tank connects medicine system respectively.
Handling process of the present utility model is as follows：Electroplating comprehensive waste water is collected by pipe network, is introduced into mixed liquor regulating reservoir,
Regulating water quality water, is pumped into the utility model integrated wastewater treatment equipment by elevator pump, initially enters chromium reduction pond, chromium is also
Former pond is used for hexavalent chrome reduction into trivalent chromium, mainly adds sodium hydrogensulfite by sexavalence by medicine system in reaction tank
Chromium is reduced into trivalent chromium.
Medicine system includes multiple medicine-chests, multiple medicine-chests is respectively communicated to chromium reduction pond, the pipeline of coagulation reaction tank, use
The metering feedback system of chemical feeding quantity and dosing speed in signal piping and the control system being connected with metering feedback system,
Control system includes the control valve set on pipeline；Multiple medicine-chests include the medicine-chest for acid adding, the medicine-chest for adding alkali, are used for
Plus sodium hydrogensulfite medicine-chest, for aggravating to catch the medicine-chest of agent, the medicine-chest for adding sodium hypochlorite, for adding aluminium polychloride
Medicine-chest, the medicine-chest for addition polymerization acrylamide.
First pass through medicine-chest plus hydrochloric acid to adjust the pH value of chromate waste water between 2~3, then by adding sodium hydrogensulfite will
Hexavalent chrome reduction is into trivalent chromium, and reselection adds piece alkali, recaptures agent, sodium hypochlorite, aluminium polychloride, polyacrylamide progress
Fine setting makes chemical feeding quantity stable in setting value.Metering feedback system can be monitored in real time to dosing speed and dose immediately, be passed through
Control valve controls the ratio of chemical feeding quantity, so as to effectively control the use cost of medicament, it is to avoid medicament causes to waste.
The water outlet gravity flow in chromium reduction pond enters coagulation reaction tank, by medicine system plus alkali, regulation pH value to 9~12, so
Aluminium polychloride coagulant is added by medicine system again afterwards, it is well mixed by stirring, makes zinc hydroxide, hydroxide
Chromium, nickel hydroxide formation flocculation sediment body, improve sedimentation function；Then the water outlet of coagulation reaction tank enters sedimentation basin, and waste water exists
Stayed for some time in sedimentation basin, using the effect of gravity, remove the flocculate precipitate in electroplating integrated sewage.As shown in Figure 2,
Buffering area, the lower end of specially left wall 1 and coagulating are separated out by twice wall between coagulation reaction tank and sedimentation basin
The bottom surface in pond is connected, and the upper end of left wall 1 and the top surface of coagulation reaction tank separate to form upper end open, the upper end of right wall 2 with
The top surface of sedimentation basin is connected, and the lower end of right wall 2 and the bottom surface of sedimentation basin separate to form lower ending opening, left wall 1 and the right side
The overlapped part of wall 2 is buffering area, and multiple tracks filter screen 3 is provided with buffering area, added the sewage after coagulant from
The upper end open of coagulation reaction tank enters buffering area, and enters sedimentation basin from lower ending opening, due to the stop of wall, it is therefore prevented that mixed
The influence that stirring action in solidifying reaction tank is produced to sedimentation basin, makes sedimentation basin maintain a preferable inactive state, is beneficial to
The sedimentation of flocculate precipitate, and because sewage from the lower ending opening of buffering area enters sedimentation basin, the hydraulic pressure of lower part is bigger, makes
Sewage enter sedimentation basin flow velocity it is more stable, reduce impact, and sewage pass through buffering area multistorey strainer mesh 3 when, can filter
Fall larger particles.
The water outlet gravity flow of sedimentation basin enters intermediate pool, and quartz sand filtration tank is lifted into through pump, further by filtering
Remove the particulate matter in waste water；Water outlet gravity flow enters clear water reserviors, the water of clear water reserviors can qualified discharge, while can act also as quartz
The backwash water of sand filtering tank.Sludge is lifted into sludge drying pond through sludge pump in sedimentation basin, is taken off in sludge drying pond
After water process, periodic cleaning.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed
Change or replacement, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should
It is defined by scope of the claims.
