Abstract
The invention relates to a dyeing wastewater biomass pretreatment technique. According to the technique, water storage tank sand filtration, activated carbon adsorption and cation adsorption are utilized to pretreat magnesium, calcium and heavy metals in tap water. No phosphorus element is added in the treatment process, thereby avoiding increasing the load to the subsequent water treatment. Sand filtration 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.
Description
Technical field
The present invention relates to textile printing and dyeing water-treatment technology field, particularly relate to the biomass pretreatment process of a kind of water of printing and dyeing.
Background technology
Printing and dyeing mill's water consumption in dyeing and finishing is processed is very big, will consume substantial amounts of water from desizing, kiering, bleaching, mercerising to dyeing, stamp, arrangement and boiler steam supply.
Textile dyeing and finishing water main source has two classes, a class to be surface water, Ru Jiang, river, Lake Water, another kind of for subsoil water, such as phreatic water, spring water etc..Surface water source abundance, but water quality is often affected by flow, season and environment, typically contains more suspended thing, such as silt, dust, microorganism and a small amount of Organic substance etc..Quality of groundwater is stably clarified, but is affected by geology, often contains more mineral.Normally used tap water is the surface water after waterworks processes or subsoil water, but the processing of tap water mainly removes oil removal by modes such as standing, flocculate and clarify or filtrations, not dealing with water-solubility impurity, some subsoil water is not even through processing.And affect the mainly water-solubility impurity of textile dyeing and finishing processing.
Dyeing and printing process is because of manufacturing procedure, processing method is different, require that water softener meets printing and dyeing parameter, in order to ensure that water obtains softening the calcium ion that conventional phosphoric acid is total with hydrogen peroxide chelating water, the calcium in water, magnesium ion are removed, makes water be softened, although water quality is softened, but having brought substantial amounts of P elements into, processed follow-up water and bring new problem, printing and dyeing effect is had a certain impact by the untreated meeting of the heavy metal element in water simultaneously.
Summary of the invention
In order to solve the problem in background technology, the present invention provides the biomass pretreatment process of a kind of water of printing and dyeing.
The biomass pretreatment process of a kind of water of printing and dyeing, comprises the following steps:
A, 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；
B, 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；
C, the water that activated carbon adsorption system processed is passed through cation-adsorption resin.
Preferably, in the described water in the cistern in step A, 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 A, 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, find that these six kinds of willows all have higher toleration and enriching (He J, Ma C to Cd, Ma Y, et al.
Cadmium tolerance in six poplar species[J]. Environmental Science and Pollution
Research, 2013,20 (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.
The biomass pretreatment process of printing and dyeing water of the present invention, use cistern sand filtration, activated carbon adsorption, cation-adsorption, magnesium in tap water, calcium and heavy metal are carried out pretreatment, in processing procedure, is added without P elements simultaneously, process to follow-up water and increase burden；The mud of sand filtration 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.
