Description

水淨化用分散液、該水淨化用分散液的製造方法、以及排放水處理方法Dispersion for water purification, method for producing the same, and method for treating effluent

本發明係關於一種使用於工業排放水等之水淨化的植物來源水淨化用分散液、該水淨化用分散液的製造方法、以及使用該水淨化用分散液的排放水處理方法。The present invention relates to a plant-derived water purification dispersion used for water purification of industrial waste water and the like, a method for producing the water purification dispersion, and a waste water treatment method using the water purification dispersion.

近年來,於工廠製造各種產品的過程中,大量產生了包含金屬離子或氟離子等無機離子之環境有害物質的廢液。 另一方面,關於此等無機離子的排放規定亦漸漸變得嚴苛。為了遵守此等排放規定,本發明人們尋求一種能將無機離子自包含無機離子的排放水中有效率地去除,且儘可能地以簡單、低成本的方式實施之無機離子的去除方法。 一直以來,就去除來自工廠排放水等不純物粒子的方法而言,有人提出了凝集沉澱法、離子交換法、使用活性碳等吸附劑之吸附法、電吸附法、及磁吸附法等。In recent years, in the process of manufacturing various products in factories, a large amount of waste liquid containing environmentally harmful substances such as metal ions and fluoride ions is produced. On the other hand, regulations regarding the emission of such inorganic ions have gradually become stricter. In order to comply with these discharge regulations, the present inventors sought a method of removing inorganic ions which can efficiently remove inorganic ions from discharge water containing inorganic ions, and which can be carried out in as simple and low-cost manner as possible. Conventionally, as methods for removing impurity particles such as factory discharge water, agglomeration precipitation method, ion exchange method, adsorption method using an adsorbent such as activated carbon, electroadsorption method, and magnetic adsorption method have been proposed.

例如,就凝集沉澱法而言,有人提出了一種方法,該方法包含:將鹼加入溶解有重金屬離子的排放水,並使排放水呈鹼性,接著使至少一部份的重金屬離子不溶解化,進而形成懸濁固狀物的步驟;將無機凝集劑加入排放水,使懸濁固狀物凝結沉降的步驟;及讓排放水通過含有黃麻菜(mulukhiya)、小松菜(komatsuna)等葉菜的陽離子交換體之吸附層的吸附步驟(例如,參照專利文獻1)。 同時,也有人提出一種凝集方法,其係將含有黃麻菜(molokheiya)、或其乾燥物、或其抽出物中至少任一者的凝集劑與高分子凝集劑混合或併用,進而使懸濁液中微粒子凝集分離(例如,參照專利文獻2)。 再者,也有人提出一種水淨化劑及使用該水淨化劑的水淨化方法,其係使用由含有植物粉末及高分子凝集劑之混合物的顆粒而成的水淨化劑 (例如,參照專利文獻3)。For example, in the case of the coagulation precipitation method, there has been proposed a method comprising: adding an alkali to the discharge water in which the heavy metal ions are dissolved, making the discharge water alkaline, and then insolubilizing at least a part of the heavy metal ions , and then the step of forming a suspended solid; the inorganic flocculant is added to the discharge water, the step of coagulation and sedimentation of the suspended solid; The adsorption step of the adsorption layer of the cation exchanger (for example, refer to Patent Document 1). At the same time, an agglutination method has also been proposed, which comprises mixing or using a polymer aggregating agent containing at least any one of molokheiya, its dried product, or its extract, and further making a suspension liquid. Coagulation and separation of neutron particles (for example, refer to Patent Document 2). Furthermore, a water purifying agent and a water purifying method using the water purifying agent have also been proposed, which use a water purifying agent composed of particles containing a mixture of plant powder and a polymer flocculant (for example, refer to Patent Document 3). ).

然而,以高速進行排放水的穩定處理時,必須導入能夠自動進行排放水淨化處理之自動化淨化裝置。特別是進行大量的排放水處理時,自動化淨化裝置係成為有效的手段。因此,期望一種淨化處理的系統結構,其係能夠適用於自動化淨化裝置,且能夠高速地使大量的排放水進行穩定之淨化處理,並顯示更優異的淨化性能。However, when stabilizing the discharge water at high speed, it is necessary to introduce an automatic purification device capable of automatically purifying the discharge water. Especially when a large amount of discharge water is treated, an automatic purification device becomes an effective means. Therefore, there is a need for a system configuration of purification treatment which can be applied to an automated purification apparatus, can stably purify a large amount of discharge water at a high speed, and exhibit more excellent purification performance.

[發明所欲解決之課題] 在自動化淨化裝置中,於使用如含有上述專利文獻1~3所記載之植物的水淨化劑,將排放水進行淨化處理時,為了發揮優異的水淨化性能,考慮了下述方法:在將水淨化劑供給至排放水時,需先將水淨化劑溶於水來製作分散液,再將該分散液供給至排放水。因為藉由將固體狀水淨化劑直接投入排放水,並使用分散液,而使水淨化成分傳導至排放液整體,故較佳。 又,根據產線的生產方式,若欲有效率地進行流動作業中的排放水淨化處理,則必須要預備分散液。因為從工廠等排出之排放水的產生量逐日變化,故尋求預先製作一定量的分散液並貯存之,必要時再使用特定的量。 再者,若進一步地考慮顧客需求,則考慮以溶有水淨化劑之分散液進行交易的情況,故可預見針對分散液的態樣會有一定需求。因此,尋求著提供低成本且能夠長期保存的分散液。 然而,上述專利文獻1~3皆未針對供給至排放水的分散液進行詳細說明,從上述專利文獻1~3的記載來看,該等專利文獻係揭示一種分散液,其係於水中分散有水淨化劑且用於供給至排放水,但該等專利文獻並未揭示分散液顯示優異的水淨化性能,並在長期保存後水淨化性能也不會下降,且即使在低成本下也能夠製作滿意的分散液。[Problems to be Solved by the Invention] In order to exhibit excellent water purification performance when purifying discharge water using water purifying agents containing plants such as those described in Patent Documents 1 to 3 in an automatic purification device, it is considered that When supplying the water purifying agent to the discharge water, a method is proposed in which the water purifying agent is dissolved in water to prepare a dispersion liquid, and then the dispersion liquid is supplied to the discharge water. It is preferable to conduct the water purification component to the whole of the discharge liquid by directly throwing the solid water purification agent into the discharge water and using the dispersion liquid. In addition, depending on the production method of the production line, in order to efficiently perform the purification treatment of the discharge water in the flowing operation, it is necessary to prepare a dispersion liquid. Since the amount of discharge water discharged from a factory or the like varies day by day, it is sought to prepare a certain amount of dispersion liquid in advance, store it, and use a specific amount when necessary. Furthermore, if the customer's needs are further considered, considering the case where the dispersion liquid dissolved in the water purifying agent is traded, it is foreseeable that there will be a certain demand for the form of the dispersion liquid. Therefore, it has been sought to provide a dispersion liquid that can be stored at low cost for a long period of time. However, none of the above-mentioned Patent Documents 1 to 3 describe in detail the dispersion liquid to be supplied to the drain water, and from the description of the above-mentioned Patent Documents 1 to 3, these patent documents disclose a dispersion liquid in which a dispersion liquid is dispersed in water. A water purifying agent and is used for supply to discharge water, but these patent documents do not disclose that the dispersion liquid exhibits excellent water purification performance, and the water purification performance does not decrease after long-term storage, and can be produced even at low cost satisfactory dispersion.

(水淨化用分散液) 本發明的水淨化用分散液係含有長朔黃麻粉末與高分子凝集劑。也就是說,長朔黃麻粉末與高分子凝集劑分散於水。 在前述水淨化用分散液中,相對於作為分散媒介的水,長朔黃麻粉末與高分子凝集劑的合計含有量為0.01質量%~0.5質量%。 前述水淨化用分散液的黏度係20mPa‧S~500mPa‧S。 又,前述水淨化用分散液中固體成分的中位徑係100μm~400μm。 滿足上述要件之本發明水淨化用分散液,其係顯示優異的水淨化性能,並在長期保存後水淨化性能也不會下降,且即使在低成本下也能夠滿意地被製作。(Dispersion liquid for water purification) The dispersion liquid for water purification of the present invention contains Changshuo jute powder and a polymer flocculant. That is to say, Changshuo jute powder and polymer flocculant are dispersed in water.

本發明人們,針對使用分散液之排放水的淨化處理進行反覆研究,發現根據分散液中水的種類,植物粉末與高分子凝集劑溶解時該分散液的黏度會變化。又,使用長朔黃麻作為植物粉末時,分散液的黏度有下降的傾向。 接著,本發明人們獲得以下見解:分散液黏度的差異會影響排放水的淨化性能,且為了獲得良好的淨化性能,有效的是某種程度地提高分散液的黏度。 又,若黏度過低,則分散液中的固體成分變得容易沉降。因此,若在製作分散液後,例如經過數日後,因為水淨化之有效成分沉澱於容器底部,將分散液注入排水槽時會殘留於容器內,結果,無法獲得充分的水淨化作用。此現象在製作分散液時,於使用(含有各種離子的)自來水及地下水時特別顯著。若使用昂貴的蒸餾水作為分散媒介,則雖然能夠某種程度地應對黏度的問題,但會產生成本方面的問題。 於實用上,被供給至排水槽的水淨化用分散液係數十~數百L的等級。因此,水淨化用分散液被保存在例如容量為200L左右的大桶(Drum)。如此一來,水淨化用分散液黏度過低時所產生之上述固體成分沉降的問題則變得顯著。然而,在製作水淨化用分散液後,直接(例如在數分鐘內)投入排水槽時,上述固體成分沉降的問題則變少。然而,因為從工廠等排出之排放水的產生量多是逐日變化,以實用性而言,尋求預先製作一定量的分散液並貯存之,必要時再使用特定的量。因此,尋求著即使長期保存也能夠抑制固體成分之沉降的水淨化用分散液。 因此,本發明人們深入研究的結果,藉由界定分散液中長朔黃麻粉末與高分子凝集劑的含有量、分散液中固體成分的中位徑、以及分散液的黏度,發現上述數值在所欲範圍內的分散液,係能夠在對於排放水保持良好淨化作用的同時,即使在長期保存後也能抑制固體成分的沉降,且即使使用較便宜的自來水與地下水,也能製作水淨化性能不會下降的水淨化用分散液。 以下,針對水淨化用分散液的具體構成進行說明。The present inventors have repeatedly studied the purification treatment of discharge water using the dispersion liquid, and found that the viscosity of the dispersion liquid varies depending on the type of water in the dispersion liquid when the plant powder and the polymer flocculant are dissolved. In addition, when longshu jute was used as the plant powder, the viscosity of the dispersion liquid tended to decrease. Next, the present inventors obtained the knowledge that the difference in dispersion viscosity affects the purification performance of drain water, and that it is effective to increase the viscosity of the dispersion to some extent in order to obtain good purification performance. Moreover, when the viscosity is too low, the solid content in the dispersion liquid tends to settle. Therefore, when the dispersion liquid is prepared, for example, after several days, the active ingredient for water purification is deposited on the bottom of the container and remains in the container when the dispersion liquid is poured into the drainage tank. As a result, a sufficient water purification effect cannot be obtained. This phenomenon is particularly remarkable when using tap water and groundwater (containing various ions) when producing a dispersion. If expensive distilled water is used as a dispersion medium, the problem of viscosity can be dealt with to some extent, but a problem in terms of cost arises. Practically, the coefficient of the dispersion liquid for water purification supplied to the drainage tank is on the order of ten to several hundred liters. Therefore, the dispersion liquid for water purification is stored in, for example, a drum (Drum) having a capacity of about 200 L. In this way, the problem of the above-mentioned settling of the solid content, which occurs when the viscosity of the dispersion liquid for water purification is too low, becomes conspicuous. However, when the dispersion liquid for water purification is prepared and directly (for example, within a few minutes) put into a drainage tank, the problem of the above-mentioned sedimentation of the solid content is reduced. However, since the amount of discharge water discharged from a factory or the like varies day by day, it is practical to prepare a certain amount of dispersion liquid in advance, store it, and use a specific amount when necessary. Therefore, the dispersion liquid for water purification which can suppress the sedimentation of solid content even if it preserve|saves for a long period of time has been demanded. Therefore, as a result of in-depth research by the present inventors, by defining the content of the longshujute powder and the macromolecular flocculant in the dispersion, the median diameter of the solid content in the dispersion, and the viscosity of the dispersion, it was found that the above-mentioned values are in The dispersion liquid in the desired range can maintain a good purification effect for discharge water, suppress the sedimentation of solid components even after long-term storage, and can produce water purification performance even when using relatively cheap tap water and groundwater.

On the other hand, when the median diameter is larger than 400 μm, the solid content is precipitated in the dispersion liquid. The solid content in the dispersion is mainly affected by the insoluble components in the Changshuo jute powder. Therefore, in order to make the above-mentioned median diameter in the above-mentioned desired range, it is preferable to adjust the relevant classification conditions while adjusting the pulverizing conditions of the long-shuo jute and classifying the long-shuo jute powder obtained by pulverization.
