Because the disposable adsorption component content of putting in is great, therefore design stirring subassembly 7 stirs it, in order to scatter it, and then promote adsorption effect, when stirring the work, at first start first shift knob 25, after controller 3 received first shift knob 25's signal, start driving motor 19, thereby make flywheel 23 on its output rotatory, and then it is rotatory to drive flywheel 23 through belt 24, further drive rotation axis 20 and rotate, because three stirring subassemblies 7 of group all overlap and establish on rotation axis 20, therefore it is rotatory and stir the water and the adsorption material in the regulation pond 2 to drive stirring board 27, because all be equipped with a plurality of round hole 28 on every stirring again, therefore make adsorption material and printing and dyeing sewage fully contact, further promoted adsorption effect.

When the dyeing wastewater is transferred to the inside of the adjusting tank 2, the second switch button 33 is actuated, and since the four heating plates are connected in series, thus, when the controller 3 receives the signal of the second switch button 33, the four electric heating plates 32 are activated to heat the inside of the regulating reservoir 2, in order to ensure the adsorption effect, the temperature in the regulating tank 2 needs to be controlled to be 15-38 ℃, the temperature controller 8 is designed for detecting and controlling the temperature in the regulating tank 2, after the heating component 9 heats the interior of the adjusting tank 2, the controller 3 is started, and after the controller receives the signal of the temperature controller 8, the temperature inside the regulating reservoir 2 is detected, when the temperature exceeds the standard, the controller 3 is controlled to open and close the heating component 9 through a computer in a remote working chamber, further ensuring that the temperature in the regulating tank 2 is always 15-38 ℃, and further ensuring the decoloring effect of the regulating tank 2.

In order to ensure the adsorption effect, the pH value of the printing and dyeing sewage in the regulating tank 2 needs to be regulated to 5-6, after sufficient carbon dioxide is injected into the regulating tank 2, the controller 3 is started, and after the controller 3 receives a signal of the pH detector 4, the pH value of the sewage in the regulating tank 2 is detected through the detection probe 38 so as to ensure that the pH value of the printing and dyeing sewage is 5-6.

When the adjusting tank 2 operates, air can be injected into the adjusting tank through the air inflation pipe 34 to perform aeration so as to prevent the sludge in the adjusting tank 2 from precipitating, and further the next process is facilitated, namely when sewage is input into the coagulating sedimentation tank, the sludge is taken away together. The existing dyeing sewage is usually alkaline waste water, a more common treatment method comprises the steps of adding an acidic substance into the existing dyeing sewage, neutralizing the acidic substance, and filtering the acidic substance, so that the dyeing sewage can be decolorized and purified, but the existing acidic substance is usually hydrochloric acid and sulfuric acid, the substance has great pollution to rivers after neutralizing the alkaline waste water, the acidic substance can corrode processing equipment, and the artificial addition has potential safety hazards, so that the substance is replaced by carbon dioxide.

After carrying out preliminary decoloration when printing and dyeing sewage in equalizing basin 2, open spiral cover 39 on the drain pipe 35 through the manual work, and then lead to the process down with the water in the equalizing basin 2, sealing washer 41 plays sealed effect, prevents leaking of gaseous and the inside printing and dyeing sewage of equalizing basin 2, and filter plug 40 then prevents leaking of adsorbing material, is favorable to it to carry out the reutilization.

It should be understood that the above-described embodiments are merely preferred embodiments of the invention and the technical principles applied thereto. It will be understood by those skilled in the art that various modifications, equivalents, changes, and the like can be made to the present invention.
