Description
Technical field
The present invention relates to a kind of post-treating method that is used to wash metal parts, optical lens, glass, electronic unit and precise part crust, on these parts surfaces, be stained with stain, as the oil of working, comprise the cutting oil and the beaming roller oil that are used for working part, slushing oil, lubricant, the cutting metal powder, be bonded at the sticking agent (wax, pitch etc.) on the optical lens, be bonded at solder flux and the liquid crystal that is bonded on the liquid crystal board on the electronic unit, the present invention also relates to be used for the detergent composition of this method.
Background technology
In general, up to the present, people's water base, half aqueous detergent of using chlorine furlong based solvent, alternative furlong based solvent, non-halogen radical solvent such as hydrocarbon or comprising tensio-active agent wash the work oil that is bonded on the working part as cutting oil, be bonded at sticking agent on the optical lens, be bonded at the solder flux on the electronic unit and be bonded at liquid crystal on the liquid crystal board.
The use of chlorine furlong based solvent is restricted because they can damage the ozone layer.There is very big problem in alternative furlong based solvent on scourability.In addition, the problem of alkyl solvent is their smell and the inflammableness that demonstrates, and therefore has very big problem on safety.
On the other hand, with regard to having the water base of less above-mentioned this class problem with regard to half aqueous detergent, when people have the Betengent product of high detergency in development, use various tensio-active agents (Japanese Patent Application Publication 150192/1995).But above-mentioned water base and half aqueous detergent all need water to carry out towards Xian (hereinafter to be referred as " towards Xian ") in general, and therefore the environmental loads towards the useless water generates of Xian is a serious problem.
In general water base, half aqueous-based cleaning process,, make water in order to remove the washing composition that is bonded in washing trough washing and the residual goods that slight stain arranged.Detergent component can be included in the flushing waste water, therefore, before discharge of wastewater is in the river, must remove these components.The most serious problem just is to handle above-mentioned flushing waste water when using water base, half aqueous detergent.
Up to the present, water base as being used for from using, remove above-mentioned detergent component in the flushing waste water that half aqueous detergent is produced so that make it can be with the method for discharging of the form of clear water or recycling, already used have: (typical example is settlement separate method: coagulation sedimentation method etc.), (typical example is membrane processing method: ultrafiltration, reverse osmosis membrane processing method etc.), (typical example is biological degradation method: activated sludge process etc.), (typical example is: the pressure floatation method for absorption method (typical example is: active carbon adsorption, foam fractionation method etc.) and flotation partition method, extraction method etc.).
Research for settlement separate method is very active, and develop good flocculation agent and comprised inorganic flocculating agent such as poly aluminium chloride (PAC) and polyiron sulfate, and polymer flocculant such as polyacrylamide.
But the problem that above-mentioned settlement separate method exists is to add the process complexity of flocculation agent, and because aggregation will come so that the form of throw out is separated, therefore need the cost regular hour to carry out separating treatment, and equipment cost also can rise.
Membrane processing method, special reverse osmosis membrane processing method is removed speed height and very effective, but is had a lot of problems at aspects such as equipment, running costs.Equally, biological degradation method also often uses, but has defective at aspects such as degradation rate, equipment scale, running costs.
Active carbon adsorption also is effectively, but because its running cost and Operating Complexity, the use of this method only is limited to limited purposes.The foam fractionation method be a kind of can be fully and effectively utilize the method for tensio-active agent lathering property, can become very big but its problem is an equipment scale, cost rises, and the object that removes is only limited to surfactant.
In addition, in the middle of flotation partition method, the pressure floatation method is the simple relatively method of a kind of equipment, but its shortcoming is its rate of removing.
In addition, about extraction method, being to carry out isolating method by add extraction agent in waste water as everyone knows, is to extract with phenol (Japanese Patent Application Publication 94257/1973), amine-based solvents (Japanese Patent Application Publication 62558/1976), water-fast negatively charged ion oil (Japanese Patent Application Publication 69/1977), the higher alcohols (Japanese Patent Application Publication 195065/1995) that is similar to the synthetic oil (Japanese Patent Application Publication 94678/1980) of wax and has 8 or an above carbon atom.
But, in the said extracted method of these file descriptions, must relatively costly extraction agent be joined in the waste water, so there are a lot of problems in it with regard to the working cost aspect.
On the other hand, the same known method (Japanese Patent Application Publication 122480/1992) of from flushing waste water, removing washing composition etc. by the cloud point of utilizing nonionogenic tenside simply and easily that also has.Yet, in aforesaid method, the problem that relates to is to have low water solubility by the washing composition itself that utilizes cloud point to separate, residual washing composition, the washing composition that particularly is retained in sealing gap and the hole can not be fallen towards Xian, can not obtain gratifying washing quality.

There is an index to can be used for determining whether said detergent composition is suitable for this process, wherein after water is with 10 times of detergent composition dilutions, to calcium chloride that wherein adds 2000ppm and mixing, then mixture was left standstill 24 hours at 25 ℃, observe it and whether be separated into two-phase, be i.e. water and the liquid phase that contains the organic solvent that is slightly soluble in water.
The post-treating method that the present invention is used to wash is suitable for separating the flushing waste water of the storage that contains relative high concentration detergent component.That is, do not equip in the habitual washing process of water storage flushed channel in common use, when carrying out towards Xian with a large amount of water, can be the detergent composition dilution that from washing trough, brings, therefore, can produce a large amount of Xian's sewage that dash, thus the equipment of increasing wastewater treatment.Yet, in the method for the invention, the wash-down water that stores can be simply with clear water exchange in about a day once, its effect is that the detergent component from taking to of discharging of over flow rinse groove and separator tank towards Xian's sink drainage is lowered to the 1/10 to 1/100 so little of general-purpose system, so just can reduce largely towards the load of Xian's sink drainage.In addition, because the flushing waste water amount of handling few (throughput of water storage flushed channel: about 200 kilograms), the scale of sepn process is also little, and facility investment also can reduce.
Method of the present invention should not be only limited to above process shown in Figure 1, and it also can be applied to spray washing and scrub process.In addition, the flushing waste water of storage not only can exchange by batch system, and can be by continuous exchange system exchange.
In such scheme of the present invention, element comprises following post-processing step: the goods to be washed that have crust with a kind of detergent composition washing that comprises anion surfactant and the organic solvent that is slightly soluble in water, water is towards Xian's said products subsequently, add polyvalent metal salt then and it is mixed with the gained flushing waste water, mixture is left standstill so that it is separated into two-phase, the liquid phase and the water that promptly include the organic solvent that is slightly soluble in water, and drainage water phase.Therefore, this post-treating method that is used for washed hardened surface has good basic washability (washing ability of stain and washing composition dash Xian Xingneng), do not need to handle on a large scale the equipment of flushing waste water and high treatment cost, and can reduce environmental loads (amount of sewage load and trade effluent).
Under detergent composition situation of the present invention, be separated and under liquid state, carry out, therefore, compare, can separate under the segregation rate faster at an easy rate with the situation of using the detergent composition that contains anion surfactant and solvent that uses at present.In addition, be slightly soluble in the separation and the extraction yield height of the organic solvent of water, its solubleness for water is very little.Therefore, very little for the load of sink drainage, and gentle friendly to environment.In addition, detergent component and stain component are extracted in the organic solvent that is slightly soluble in water, so they can obtain handling at an easy rate.
