Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, Figure 2 and Figure 3, the present invention comprises the following steps the process that processing of stone settlement of sewage is carried out:
First, the sewage that machinery equipment 1 processing stone material produces carries out coagulating sedimentation via micro computer water monitoring device 2 and micro computer water quality acid-alkali accommodation device 3 pairs of sewage in ditch 4 and potential of hydrogen regulates process, and its treating processes is:
The numerical value that online pH detector in micro computer water monitoring device 2 and under meter are monitored provides plate to be sent to the microcomputer data dash receiver of micro computer water quality acid-alkali accommodation device 3 by microcomputer data.The scale parameter that adds of flocculation agent inputs microcomputer data dash receiver by the artificial character according to stone material and waste strength.The first electrically operated valve controlled separately by PLC control system, the second electrically operated valve, the parameter of the 3rd electrically operated valve received by microcomputer data dash receiver throw in a certain proportion of flocculation agent, alkali lye or acid solution in trend sewage.Flocculation agent can selective polymerization aluminum chloride or polyaluminium sulfate, and alkali lye can select concentration to be in the pH compound alkali of about 5mol/L, pH and powder or sodium hydroxide, and acid solution can select concentration to be the hydrochloric acid of 1mol/L.Sewage after flocculation agent precipitation process and potential of hydrogen regulate enters sewage collecting basin 5.
Then, certainly mixing formula sewage pump 6 will stir through the sewage of potential of hydrogen process in sewage collecting basin 5 and be promoted to guide pipe 8, injects primary precipitate container 7 carry out first time precipitation in guide pipe 8 via the buffering of buffer substrate tablet 9.Buffer substrate tablet 9 can cushion flow velocity when sewage injects and make sewage directed flow, reduces when waste liquid injects impact sedimentary in container.
Then, when sewage precipitates and expires to vessel port in primary precipitate container 7, flowed into the annular clear water ditch 11 of vessel port by profile of tooth spoiler 10, sewage through profile of tooth spoiler 10 can precipitate more even.When the liquid level in annular clear water ditch 11 overflows across clear water thrust-augmenting nozzle 12, liquid just can inject the guide pipe of retaining precipitation vessel 16 along clear water thrust-augmenting nozzle 12, and carries out secondary sedimentation by buffer substrate tablet injection retaining precipitation vessel 16.
Finally, after secondary sedimentation, water quality is very limpid, and water-based is moderate, can meet the needs that processing of stone is produced completely, can not produce any destruction and impact to stone material and machine.When clear water water level is higher than clear water output 14, namely accessible machine uses.The precipitation vessel of retaining is simultaneously provided with retaining deposit water level 15, can carry out retaining with the different demands in satisfied production to the clear water after precipitation.
The powder precipitated in primary precipitate container 7 and retaining precipitation vessel 16 is starched the pressure that can produce by waterhead and is starched thrust-augmenting nozzle 13 process that follow-up precipitation treatment device carries out precipitating of leading by powder and reclaim.
The above embodiment only have expressed embodiments of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
