Abstract
A bleaching and dyeing and papermaking wastewater treatment method is characterized by comprising the following treatment processes: wastewater receiving and storing and settling, medicine-adding decoloring regulation, separation of suspensions, high-altitude jet-flow oxidation treatment, removal and decomposition of noxious substances in water, regulation of pH value and reflux recycling. A substance added during the process of medicine-adding decoloring regulation is chloric acid or hypochlorite. During the process of high-altitude jet-flow oxidation treatment, an infusion tube is adopted to send a treatment fluid to high altitude, and oxidation treatment is performed by an atomization plant.
Description
Technical field
The present invention relates to a kind ofly to bleaching and dyeing, the method for paper-making industry sewage disposal.
Background technology
Through retrieval Patent documents of interest, not yet retrieve at present identical with the present invention a kind ofly to bleaching and dyeing, the method for paper-making industry sewage disposal.Along with people are to the pay attention to day by day of environment protection, pollution-free, energy-conservation, water-saving production model is progressively by people's extensive concern.Existingly to bleaching and dyeing, the sewage disposal of paper industry adds medicament after generally taking sewage to receive and keep, after multistage quick-fried vapour biochemical treatment, then discharge after precipitation.Owing to taking multistage water lift, quick-fried vapour biochemical treatment clearance low, add to cost higher, so bring very large difficulty to waste water control.
Summary of the invention
The object of the invention is to provide one to have investment little, can realize recycling a kind ofly to bleaching and dyeing, the method for Sewage.
To achieve these goals, consideration investment little, can on the basis of sewage recycling use, adopt and sewage is received and kept to precipitation, dosing decolouring adjustment, separating suspension, high-altitude jet flow oxide treatment, the nuisance removed in water of decomposition, regulated the treatment process of potential of hydrogen, reflux cycle use to process sewage, it is characterized in that: described dosing decolouring regulates the material added in operation to be chloric acid or hypochlorite; Described high-altitude jet flow oxide treatment operation adopts tubing that treatment solution is delivered to high-altitude, and the method through atomisation unit process carries out oxide treatment.
Advantage of the present invention is: owing to adopting chloric acid or hypochlorite as decolouring conditioning agent, and adopt the residual chlorine ion in the mode Transformatin liquid of high-altitude atomizing and oxidizing, thus treatment process is simplified; Because equipment investment is little, operating cost is low, and water quality is after treatment reusable, thus achieves recycling of water treatment, decreases the pollution to environment, so there is very large practical and popularizing value.
Below with reference to embodiment, the present invention is conducted further description;
Of the present inventionly to bleaching and dyeing, paper making sewage processing method comprises sewage harvesting precipitation, dosing decolouring adjustments, separating suspension, high-altitude jet flow oxide treatment, the nuisance removed in water of decomposition, regulate the treatment process of potential of hydrogen, reflux cycle use.After sewage being stored to settling tank in production, add AlCl
3precipitation agent, adds chloric acid or clorox, makes its pH value carry out desolventing technology about 7 after stirring precipitation; After the throw out of generation is separated with suspended substance, then by infusion pump the liquid through desolventing technology is delivered to and carry out atomization in high aerial atomization processing device and process.The liquid of atomization with the abundant catalytic oxidation process of the oxygen in air after, to fall back to etc. in hopper.After harvesting, add medicament and remove objectionable impurities, regulate pH value to required numerical value, then obtain the liquid after processing, the liquid after process is sent back in production by pipeline, then achieves the object recycled.
