Description
Technical Field
The utility model relates to a sewage pretreatment dosing system.
Background
The existing industrial wastewater comprises printing and dyeing wastewater, tanning wastewater, papermaking wastewater, electroplating wastewater, semiconductor wastewater, storage chemical wastewater, sodium sulfate wastewater, vanillin wastewater, coking wastewater, metallurgical wastewater, pharmaceutical wastewater, fermentation wastewater and the like. In recent years, with the development of economy, the pollution of chemical wastewater to the environment is aggravated, most of the chemical wastewater discharged in the production process of chemical products is organic pollutants which are complex in structure, poisonous and harmful and difficult to degrade biologically, and the treatment difficulty is high. The existing sewage treatment system can not carry out selective targeted pretreatment aiming at different industrial sewage, which causes great load influence, loss, influence on the service life and comprehensive treatment effect on a subsequent core filtration processor.
SUMMERY OF THE UTILITY MODEL
The utility model discloses shortcoming to prior art exists provides a sewage preliminary treatment system of offeing medicine, and simple structure can carry out selectivity preliminary treatment to sewage, alleviates the loss of back channel core treatment filter, improves the filter effect.
Therefore, the invention adopts the following technical scheme: including the primary treatment bucket, the primary treatment bucket connect the secondary treatment bucket, the exit end of secondary treatment bucket passes through the pump body and tube coupling to storage water tank, the primary treatment bucket in set up the filter, the secondary treatment bucket on connect first doser and second doser through pipeline and valve respectively, first doser in add the PH regulator, the second doser in add quality of water purifying agent, the secondary treatment bucket in still set up agitating unit and PH meter, valve and agitating unit's the equal connection director of switch, the second doser connect constant delivery pump and time-recorder, the constant delivery pump with the time-recorder is connected with the controller.
The second doser is connected with a dosing pump and a timer, and the dosing pump and the timer are connected with the controller.
The stirring device comprises a vertical stirring shaft, and a plurality of stirring blades are arranged on the outer side of the stirring shaft from top to bottom.
The primary treatment barrel, the secondary treatment barrel and the water storage tank are all provided with liquid level meters.
The PH meter and the liquid level meter are both connected with the controller and further comprise alarms connected with the controller, and the alarms are given when the numerical values of the PH meter and the liquid level meter exceed set values.
And a multi-stage filter screen is arranged in the first-stage treatment barrel.
The beneficial effects of the utility model reside in that: through the separation of primary treatment bucket to sewage preliminary treatment, the rethread secondary treatment bucket carries out the pH value and adjusts, to different pollution sources waste water, puts into water purification agent in the second doser and carries out the preliminary treatment, gets rid of the organic pollutant of aquatic. The water quality purifying agent is put in at regular time and quantity to achieve the best putting effect, and the sewage is fully mixed and treated by matching with the stirring device to achieve a better treatment result. The utility model discloses alleviate the loss of back way core processing filter, valve and measurement display data on each pipeline are by main control unit supervisory control, realize the control management that becomes more meticulous.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The sewage pretreatment dosing system comprises a primary treatment barrel 1, wherein the primary treatment barrel is connected with a secondary treatment barrel 2, the outlet end of the secondary treatment barrel is connected to a water storage tank 3 through a pump body and a pipeline, a filter is arranged in the primary treatment barrel, the secondary treatment barrel is connected with a first doser 5 and a second doser 6 through a pipeline and a valve respectively, a PH regulator is added in the first doser, a water purifying agent is added in the second doser, a stirring device and a PH meter 7 are further arranged in the secondary treatment barrel, and switches of the valve and the stirring device are connected with a controller 8.
The second doser is connected with the dosing pump and the timer, and the dosing pump and the timer are connected with the controller. The stirring device comprises a vertical stirring shaft, and a plurality of stirring blades are arranged on the outer side of the stirring shaft from top to bottom. Liquid level meters 4 are arranged on the primary treatment barrel, the secondary treatment barrel and the water storage tank. The PH meter and the liquid level meter are both connected with the controller, the liquid level meter further comprises an alarm connected with the controller, and the alarm is given when the numerical values of the PH meter and the liquid level meter exceed the set values.
The utility model discloses the processing flow is as follows: the sewage is subjected to multistage filtration treatment in a primary treatment barrel and then enters a secondary treatment barrel, a PH agent or/and a water quality purifying agent are/is selectively added according to the source of the sewage, the mixture is stirred to be uniformly mixed, and the treated sewage enters a water storage tank. Effectively reduces the loss of a subsequent core treatment filter and improves the comprehensive treatment effect.
The above description is only an example of the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
