Chemical laboratory waste discharge is divided into two classes, and a class is the dangerous waste liquid with high density, and this class waste liquid has higher hazardness, is generally independent collection, then transfers to have the unit that processes qualification and process; And another kind of be that usually test produces, and the comprehensive waste liquid of acid, alkali, heavy metal, organism that produces such as cleaning experiment equipment, glassware, the output of this class waste liquid is large, complicated component, and hazardness is easily ignored by people, there is greatly testing crew directly experimental waste liquid to be poured in water drain, finally rivers and lakes and groundwater resource are worked the mischief.
Along with the raising to environmental quality requirement, environmental protection department could discharge after requiring laboratory that wastewater treatment is reached to emission standard, but due to experiment waste water complicated component, adopt traditional technique for treating industrial wastewater, be difficult to play comparatively desirable treatment effect; And on the other hand, for some middle-size and small-size experimental units, because waste water output is less, and generation time is indefinite, adopt existing treatment process also to there is certain enforcement difficulty.
Summary of the invention
The object of the present invention is to provide a kind of easy enforcement, compact construction, is applicable to medium and small experimental unit and uses, and the good laboratory waste water treatment device for the treatment of effect.
For reaching above-mentioned technical purpose, the present invention realizes by the following technical solutions: a kind of laboratory waste water treatment device, comprise: for the holding tank of temporary waste liquid, the neutralization precipitation case being connected with holding tank, be arranged on the acid proof pump between holding tank and neutralization precipitation case, holding tank is provided with collection funnel, it is characterized in that: described collection funnel bottom is connected with holding tank by upper and lower roundabout S pipe, in collection funnel, be provided with filter bowl, collection funnel upper end is provided with sealing cover, collection funnel sidewall is connected with flushing pipeline, flushing pipeline is used for connecting running water pipe, and be provided with switch-valve, PH meter is installed on described neutralization precipitation case, and PH meter is arranged on the position, middle and lower part in neutralization precipitation case, neutralization precipitation case top is provided with three dispensing kits, in neutralization precipitation case, be provided with horizontal main shaft, main shaft is provided with stirring rake, is provided with heating core in main shaft, and main shaft two ends are fixed on neutralization precipitation case sidewall by bearing, and one end is connected with drive-motor, neutralization precipitation case sidewall is provided with clear liquid discharging pipe, and upper end is provided with vapor pipe, and clear liquid discharging pipe and vapor pipe are all connected with active carbon purifying device, neutralization precipitation case bottom is subsider, and subsider cross section is del, small top and big bottom, and lower end is fillet, is convenient to collecting precipitation, subsider bottom is provided with discharge auger, and discharge auger discharging mouth is connected with separating centrifuge, and separating centrifuge is provided with discharge port and liquid discharge pipe, and liquid discharge pipe connects active carbon purifying device.
The principle of work of this device is: chemical wastewater provisional storage in holding tank that laboratory produces, reach after certain amount, by acid proof pump, pump in neutralization precipitation case, the PH showing according to PH meter adds neutralizing agent by dispensing kit, can add fast response by stirring rake and heating lamp mode, after PH is adjusted to 6-9, stop stirring, and add appropriate Fe
3+make waste liquid accelerate sedimentation, when precipitation no longer produces, the clear liquid in neutralization precipitation case can be discharged after active carbon purifying device filters; The throw out producing in neutralization precipitation case is finally deposited in subsider, by discharge auger, is delivered in separating centrifuge and is dewatered, and after final solids mummification, collects, and isolated liquid can discharge after active carbon purifying device is processed.
Advantage of the present invention: collection funnel adopts S pipe to be connected with holding tank, and stopping property is strong, very convenient while pouring chemical experiment waste liquid into; Neutralization precipitation case has neutralization, precipitates two kinds of functions, has greatly simplified process for treating waste liquor, and it adopts full-closed structure, can avoid evaporating; It adopts integrated design, compact construction, simple, and acquisition cost is low, is applicable to middle-size and small-size laboratory and purchases use; Its processing ease, processing step is less, and exploitativeness is strong, has solved and has tested the large problem of wastewater treatment enforcement difficulty in the past; Waste water can reach non-pollution discharge after treatment, and waste solid can reuse or focus on.
