Abstract
The invention provides a dyeing waste water treating agent and a preparing method thereof. The waste water treating agent is prepared from the following ingredients of 10-15 parts of sodium percarbonate, 0.1-0.3 part of tetraphenyl ferroporphyrin, 10-20 parts of potassium ferrate, 2-4 parts of kieselguhr and 20-40 parts of lignin. The preparing method comprises the following steps of adding the kieselguhr and the lignin into a powder stirring machine at first, quickly stirring and evenly mixing the kieselguhr and the lignin, then adding the tetraphenyl ferroporphyrin and finally adding the sodium percarbonate and the potassium ferrate to prepare the dyeing waste water treating agent. The dyeing waste water treating agent is solid powder and is easy to store and use. When the dyeing waste water treating agent is added into water, the COD of dyeing waste water can be reduced in a short time, and the dyeing waste water can reach the emission standard.
Description
Technical field
The present invention relates to the dirty water decontamination handles field, particularly to a kind of dyeing and printing sewage inorganic agent and preparation method thereof。
Background technology
Dyeing waste water is the waste water that the printing and dyeing mill that processing cotton, fiber crops, chemical fibre and blending product thereof are main discharges。The dyeing waste water water yield is relatively big, and 1 ton of textile water consumption 100-200 ton of every dyeing and printing process, wherein 80-90% becomes waste water。Textile printing and dyeing wastewater has the features such as the water yield is big, organic pollution content is high, alkalescence is big, change of water quality is big, belongs to one of intractable industrial wastewater, containing dyestuff, slurry, auxiliary agent, oil preparation, soda acid, fiber impurity, sand class material, inorganic salt etc. in waste water。
The processing method that physico-chemical process, biochemical process, chemical method and several technique combines is had for the main method for the treatment of of dyeing wastewater, and the pretreatment in wastewater treatment is primarily to and improves waste water quality, remove float and the impurity that can directly settle, regulate waste water quality and the water yield, reduction wastewater temperature etc., improve the whole structure of wastewater treatment, guaranteeing the stability of whole process system, therefore pretreatment has extremely important status in treatment of dyeing wastewater。
Present stage processes the method for dyeing waste water, it is necessary to biochemical treatment, and the time of process is long, and after materializing strategy, COD value still can not reach discharge standard, it is impossible to enough deep pyrolytic Organic substances。
Summary of the invention
In order to solve problem above, the present invention provides a kind for the treatment of of dyeing/printing wastewaters, comprises following components:
SODIUM PERCARBONATE 10-15 part；
Tetraphenylporphyrin ferrum 0.1-0.3 part；
Potassium ferrate 10-20 part；
Kieselguhr 2-4 part；
Lignin 20-40 part。
Described SODIUM PERCARBONATE particle diameter is 0.5-2mm, and the purpose of SODIUM PERCARBONATE is to provide alkali condition, and can after being added to water body, it is possible to slow releasing hydrogen peroxide, reacts for subsequent metal coordination compound。
Described tetraphenylporphyrin ferrum is selected from tetrasulfonic acid base ferrous porphyrin, the one in tetracarboxylic ferrous porphyrin, and the addition of tetraphenylporphyrin ferrum with the SODIUM PERCARBONATE hydrogen peroxide with the use of the release of, catalysis SODIUM PERCARBONATE, can discharge the active substance with relatively Strong oxdiative ability。
Described diatomaceous fineness is 100-500 order, and kieselguhr has stronger absorbability, it is possible to adsorbed by the impurity of dyeing and printing sewage, facilitates oxidizing component to act on the surface of absorption, it is possible to depth degradation organic pollution。
Described lignin is aminated lignin, and aminated lignin has stronger flocculation, it is possible to the impurity that the volume that can not be acted on by Oxidation is bigger flocculates。
The preparation method that the present invention also provides for a kind of dyeing and printing sewage inorganic agent, comprise the following steps: in powder mixer, be firstly added kieselguhr and lignin, quickly stirring makes its mix homogeneously, it is subsequently adding tetraphenylporphyrin ferrum, it is eventually adding SODIUM PERCARBONATE and potassium ferrate, prepares dyeing and printing sewage inorganic agent。
There is advantages that
Dyeing and printing sewage inorganic agent prepared by the present invention is solid state powder, it is easy to stores and uses, can be reduced by the COD of dyeing and printing sewage at short notice, reach discharge standard after adding water body。
Detailed description of the invention
Embodiments of the invention addressed below。The element described in one embodiment of the invention and feature can combine with the element shown in one or more other embodiment and feature。It should be noted that, for purposes of clarity, explanation eliminates expression and the description of unrelated to the invention, parts known to persons of ordinary skill in the art and process。
Embodiment 1
The present embodiment provides a kind of sewage-treating agent and preparation method thereof:
SODIUM PERCARBONATE 10 parts；
Tetraphenylporphyrin ferrum 0.1 part；
Potassium ferrate 1 part；
2 parts of kieselguhr；
Lignin 20 parts。
Being firstly added kieselguhr and lignin in powder mixer, quickly stirring makes its mix homogeneously, is subsequently adding tetraphenylporphyrin ferrum, is eventually adding SODIUM PERCARBONATE and potassium ferrate, prepares dyeing and printing sewage inorganic agent。
Embodiment 2
The present embodiment provides a kind of sewage-treating agent and preparation method thereof:
SODIUM PERCARBONATE 15 parts；
Tetraphenylporphyrin ferrum 0.3 part；
Potassium ferrate 20 parts；
4 parts of kieselguhr；
Lignin 40 parts。
Said components is mixed by the step described in embodiment 1, namely obtains sewage-treating agent。
Embodiment 3
The present embodiment provides a kind of sewage-treating agent and preparation method thereof:
SODIUM PERCARBONATE 12 parts；
Tetraphenylporphyrin ferrum 0.2 part；
Potassium ferrate 15 parts；
3 parts of kieselguhr；
Lignin 30 parts。
Said components is mixed by the step described in embodiment 1, namely obtains sewage-treating agent。
Implementation result:
Processing sewage: take the sewage that printing and dyeing mill finally discharges, detecting the COD that expires is 2200, colourity 50 DEG C。
| Embodiment 1 | Embodiment 2 | Embodiment 3 | |
| COD | 84 | 63 | 73 |
