Abstract
A method of adsorbing printing and dyeing waste water with straw after plasma treatment includes the following steps: (1) cleaning the straw with clear water to remove impurities on the straw; (2) performing impurity removal to the straw under an alkaline condition at 80-100 DEG C with the pH being 8-10; (3) performing plasma treatment to the straw after impurity removal, wherein the treatment power is 200 W, air pressure is 10 Pa and treatment time is 7 min, and baking the straw at 130 DEG C for 5 min; and (4) adsorbing the printing and dyeing waste water with the straw obtained through the step (3). In the invention, the straw is subjected to surface modification under glow discharge plasma. The method of adsorbing printing and dyeing waste water is free of any chemical substances and is free of generation of secondary pollution. The preparation method of the straw is environment-friendly in the whole pre-treatment system and is simple in operation and low in cost. The straw, compared with straw being not subjected to the pre-treatment, is higher in adsorption performance, so that the method has a better industrial application prospect.
Description
Technical field
The present invention relates to method of wastewater treatment, particularly relate to a kind of plasma treatment is carried out to stalk after adsorb the method for dyeing waste water.
Background technology
The improvement of waste water from dyestuff is the focus that chemical industry environmental protection industry is paid close attention to.Because China's printing and dyeing industry mostly is small lot batch manufacture, major part is intermittently operated, waste water is discontinuity discharge, thus water quality and quantity excursion is large, waste water complicated components, concentration are high, colourity is dark (500 ~ 200,000 times), organic component in the waste water discharged is parent mainly with aromatic hydrocarbons and heterocyclic compound greatly, and with colour developing group (as-N=N-,-N-0) and polar group (as-S03Na ,-OH ,-NH2).Because DYE PRODUCTION is wide in variety, and towards anti-light solution, anti-oxidant, antibiooxidation future development, Conventional waste water treatment technology is difficult to remove these organic components.And absorption method is particularly suitable for the process of the more difficult waste water from dyestuff of biochemical degradation.Therefore, in recent years, environmental project circle more and more payes attention to the Study and appliance of cheapness, efficient, Low Cost Sorbents.In these adsorbents, stalk is more and more subject to people's attention because of the special performance of the native biopolymer that it has.
The general name of stalk ripe crops cauline leaf part, containing a large amount of-NH and-OH group in molecule, has very strong absorption
Ability, oneself is widely used in the removal of toxic heavy metal ion in industrial wastewater.Containing-NH and-OH in stalk construction unit, therefore can carry out the number of chemical such as acidylate, etherificate, alkylation, esterification, carboxy methylation and sulphation to it and modify to improve physicochemical properties, expand its range of application further.But these method of modifying need through numerous and diverse chemical reaction process, and the organic solvent of at substantial, environment friendly is poor.
According in high vacuum environment, oxygen or inert gas form high-octane plasma by plasma producing apparatus, bombard the surface of agricultural crop straw, and following physicochemical change occurs:
(1) the part macromolecular chain on stalk surface disconnects, form the free radical that chemical reactivity is high: the free radicals such as the oxygen atoms phase ion that (2) exist with plasmoid, rapidly and the combined with radical on stalk surface, new chemical bond is formed; (3) stalk surface is bombarded and is etched, and microstructure, by smooth roughening, is conducive to the infiltration of dyestuff.These changes can improve the binding ability of agricultural crop straw and dyestuff.
Summary of the invention
The object of this invention is to provide a kind of plasma treatment is carried out to stalk after adsorb the method for dyeing waste water, the method is simple to operate, environmental friendliness, and the adsorbent prepared by the method has higher absorption property.
In order to solve the technical problem in background technology, the present invention by the following technical solutions:
Adsorb a method for dyeing waste water after plasma treatment is carried out to stalk, step 1: clean water treatment is carried out to stalk, remove stalk surface impurity; Step 2: under alkali condition, removal of impurities is carried out to stalk, temperature is 80 degree-100 degree, and PH is between 8 to 10; Step 3: by the stalk plasma treatment after removal of impurities, processing power 200W, air pressure 10Pa, the processing time is 7min, is finally under the condition of 130 DEG C in temperature, bakes 5min; Step 4: the stalk utilizing step 3 to obtain adsorbs dyeing waste water.
Further, wherein the solution of 5% naoh concentration is used to carry out removal of impurities to stalk in step 2.
Further, wherein the used gas producing plasma of step 3 is oxygen, nitrogen, inert gas or air.
Further, wherein stalk comprises straw and/or wheat straw.
Beneficial effect of the present invention: (1) glow discharge plasma of the present invention modifies stalk surface, the method for absorption dyeing waste water dyestuff, does not add any chemical substance, does not produce secondary pollution, whole pretreatment system environmental friendliness.
(2) preparation method is simple to operate, with low cost, and its absorption property, than high without pretreated stalk, has more the application prospect of industrialization.
