Abstract
The invention relates to a dyeing wastewater biomass treatment technique. The technique for treating dyeing wastewater comprises the following steps: primary filtration, reducing decolorization, water storage tank sand filtration, activated carbon adsorption and cation adsorption. Dyeing sludge applied to poplar planting provides calcium, magnesium and other beneficial substances required by poplar planting, and the high adsorptivity of the poplar for heavy metals is utilized, thereby lowering the textile heavy metal treatment cost and changing wastes into valuable substances. The spunlace nonwoven fabric blended from terylene fiber scraps and bamboo fiber scraps is adopted, thereby reducing the waste, and enhancing the adsorption capacity for magnesium, calcium and other elements in water.
Description
Technical field
The present invention relates to textile printing and dyeing water-treatment technology field, particularly relate to a kind of dyeing waste water biomass processes technique.
Background technology
Textile industry is one of pillar in current economic development, but a lot of sewage can be produced in terms of weaving face fabric printing and dyeing and cause extremely serious environmental pollution, even the water eutrophication in river still can be made after treated sewage discharge, thus cause the overpreading of the plant such as Herba Eichhorniae, cyanophyceae, affect whole ecosystem, also have a lot of manufacturers to select not process sewage for very small profits and silently discharge.Therefore arranging a low cost, the waste water treatment process that waste water can be made to be utilized effectively extremely is necessary.
At present, the process technique of dyeing waste water is a lot, and representative one is to directly utilize the traditional approach that chemical method carries out processing, and which recovery utilization rate is low, and the waste water processed of discharge still contains substantial amounts of harmful substance, and cost is high, and efficiency is low；Two is to utilize plasma exchange process, and this kind of method requires height to operator, is accomplished by strengthening the input in terms of the high talent for current textile industry in this respect, and waste water is in the state of eutrophication after having processed.
Summary of the invention
In order to solve the problem in background technology, the present invention provides a kind of dyeing waste water biomass processes technique.
A kind of dyeing waste water biomass processes technique, comprises the following steps:
A, the waste water introducing filtering ponds discharged by printing and dyeing workshop, add filter aid in waste water, filter, float therein filtered out after sewage flocculation, obtain precipitate, remaining containing coloured fine suspension and solute；
B, waste water after single filter add reproducibility decolorising agent, processes direct dyeing waste water, be allowed to react with direct dyes generation reduction-decolor therein, so that the dye molecule formation deoxidization, degradation product in waste water；
C, being passed through by tap water in sealing cistern, described sealing columns base is Sand Filtration System, is ceaselessly passed through in cistern by carbon dioxide, processes 5-8min, and installs gas recovery system and reclaim carbon dioxide；
D, the water processed in cistern is passed through activated carbon adsorption system, is 0.2-0.5m/min by flow rate set, is set as 3-5min by the time；
E, the water that activated carbon adsorption system processed is passed through cation-adsorption resin；
F, by water resin processed for cation-adsorption, be re-used in dyeing and printing process.
Preferably, the described precipitate in step A is as the main component in the plantation base manure of cottonwood or base manure.
Preferably, in the described water in the cistern in step C, the concentration of EDTA is set as 0.5-1.5g/L, and the concentration of sodium gluconate is set as 1-6g/L, sodium tert-butoxide 0.1-1.5g/L.
Preferably, consisting of of the described Sand Filtration System in step C, upper strata is fine sand, and middle level is the spun-laced nonwoven fabric of polyster fibre leftover pieces and bamboo fibre leftover pieces blending, and lower floor is gravel.
Preferably, the described upper strata in Sand Filtration System and middle level, to change once every the 1-3 month, the Sand Filtration System changed can be as the main component in the base manure of plantation cottonwood or base manure.
What beauty etc. analyzes gray poplar, Populus deltoides Bartr.cv., European-American Poplar, 84K poplar, Populus nigra, the six kinds of willows of the Populus popularis molecular physiology response mechanism to Cd stress, finds that these six kinds of willows all have higher toleration and enriching (He J, Ma C, Ma to Cd
Y, et al. Cadmium tolerance in six poplar species[J]. Environmental Science and
Pollution Research, 201320 (1): 163-174.).Wu Yanhua etc. have studied south, capital Soils In The Region Characteristics of Heavy Metal Pollution and willow recovery dynatron effect, find that cottonwood is leaf to the absorption content sequence of Cd in soil > branch skin > root bark > root timber > peel of stem > branch material > stem material (Wu Yanhua. south, capital Soils In The Region Characteristics of Heavy Metal Pollution and willow recovery dynatron effect [master thesis]. The Chinese Geology Univ. (Beijing), 2005).
Willow is a kind of to have certain heavy metal accumulation ability plant, its biological study also there is certain basis, therefore the present invention chooses willow and the heavy metal pollution produced in textile industry is carried out biomass processes, heavy metal is extracted from soil willow aerial parts, thus reach effectively to process the content of heavy metal in waste water, carry out harvesting afterwards to be uniformly processed, be a kind of method of effective process heavy metal pollution.
Dyeing waste water biomass processes technique of the present invention, uses single filter, reproducibility decolouring, cistern sand filtration, activated carbon adsorption, cation-adsorption, processes dyeing waste water；Printing and dyeing sludge is applied to willow plantation, had both provided the benefit materials such as the calcium needed for willow plantation, magnesium, and also utilized the high adsorption of willow heavy metal, thus reduce the processing cost to weaving heavy metal, turn waste into wealth；Use polyster fibre leftover pieces and the spun-laced nonwoven fabric of bamboo fibre leftover pieces blending, both decreased waste, and also improved the absorbability of the element such as magnesium, calcium in water.
