Abstract
The invention provides an ink waste water treatment device. The ink waste water treatment device is sequentially provided with an acidification pool, an alkaline water tank and an ink paining machine according to a waste water processing process. The acidification pool is provided with an acid (sulfuric acid, muriatic acid and citric acid) feeding device for automatically feeding sulfuric acid into the acidification pool to enable the pH value of the acidification pool to be 3-4. The alkaline water tank is provided with a caustic soda feeding device for automatically feeding sulfuric acid into the alkaline water tank to enable the pH value of the alkaline water tank to be 8-9. An MF filter and a UF filter are sequentially arranged in the ink paining machine according to the waste water processing process.
Description
Technical field
The invention belongs to the technical field of waste water processing of environmental engineering, be specifically related to a kind for the treatment of unit of water color ink waste water.
Background technology
Ink pigment used has fast light and heat-resistant stability, acidproof, alkaline-resisting, resistance to conventional oxygenant usually, has good tinting strength, opacifying power and sublimation fastness.Conventional phthalocyanine pigment, kind is more, and bright in colour, strong coloring force, fastness is good, is widely used in printing, coating, ink etc.In print production process, can produce the printing ink wastewater of high chroma, the discharge of waste water intermittence, water quality and quantity changes greatly in time, adds to the difficulties to waste water engineering design, operational management.
Chinese patent CN 103482822 A discloses a kind of Pispose printing ink waste water treatment process, belongs to print field technical field of waste water processing.Comprise the following steps: printing ink wastewater is through air flotation pool, mix mutually with sanitary sewage at equalizing tank, waste water is again through anaerobic pond, one-level Aerobic Pond, the process of secondary Aerobic Pond, then through the precipitation of second pond, carry out solid-liquid separation, air flotation pool, anaerobic pond, mud in second pond enters sludge thickening tower under the effect of sludge pump, mud is after concentrated, be evacuated to plate-and-frame filter press with pneumatic diaphragm pump to dewater, press dry rear mud cake labor cleaning pack, filtrate then flows back to wastewater equalization pond, but this device structure is very complicated, the cost of process water color ink waste water is too high, waste strength after process is still very high.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art part, the object of the present invention is to provide that a kind of structure is simple, waste water treatment efficiency is high and the lower printing ink wastewater treatment facility of waste strength after process, to overcome defect of the prior art.
To achieve these goals, the invention provides a kind of printing ink wastewater treatment facility, described printing ink wastewater treatment facility is disposed with acid out treating pond, alkaline water tank and ink machine according to wastewater treatment process.
Described acid out treating pond is provided with throws in acid material (sulfuric acid, hydrochloric acid, citric acid) with the sulfuric acid throwing device making the potential of hydrogen of acid out treating pond remain on PH3-4 from trend acid out treating pond;
Described alkaline water tank is provided with throws in caustic soda with the caustic soda throwing device making the potential of hydrogen of alkaline water tank remain on PH8-9 from trend alkaline water case;
