Description
本創作係與廢水處理技術有關，更詳而言之是指一種可同時將廢水中氨氮成分去除之複合式氨氮廢水處理系統者。This creation is related to wastewater treatment technology, and more specifically refers to a compound ammonia nitrogen wastewater treatment system that can simultaneously remove ammonia nitrogen components from wastewater.
按，我國環保法規中針對事業、污水下水道系統及建築物污水處理設施之放流水，訂有相關適用範圍、水質項目及限值之標準，其中，針對事業、污水下水道系統及建築物污水處理設施之廢污水，其水質項目中訂有氨氮之限值，主要因廢污水中氨氮在硝化過程會消耗水中溶氧，造成水質之惡化。According to China's environmental protection regulations, the discharge water for the business, sewage sewer system and building sewage treatment facilities is subject to relevant standards, water quality projects and limit standards, including for business, sewage sewer systems and building sewage treatment facilities. The waste water has a limit of ammonia nitrogen in its water quality project, mainly because ammonia nitrogen in the waste water will consume dissolved oxygen in the nitrification process, resulting in deterioration of water quality.
習知廢污水中氨氮成份之去除技術有很多，例如生物處理法、化學處理法及物理處理法，其中，化學處理法之主要機制為氧化還原反應，亦即利用廢污水中的氨氮成份(NH3 -N)可與氯系氧化劑(如Cl2 等)氧化反應成氯胺(NH2 Cl、NHCl2 、NCl3 )後，再氧化分解形成氮氣與氫氣逸出而去除，此方法通常稱為折點加氯法，折點加氯法之詳細地定義與實施條件此處不予贅述。There are many techniques for removing ammonia nitrogen in waste water, such as biological treatment, chemical treatment and physical treatment. Among them, the main mechanism of chemical treatment is redox reaction, that is, the use of ammonia nitrogen in waste water (NH 3- N) can be oxidized with a chlorine-based oxidizing agent (such as Cl 2 ) to form chloramine (NH 2 Cl, NHCl 2 , NCl 3 ), and then oxidatively decomposed to form nitrogen and hydrogen to escape and be removed. This method is generally called The detailed definition and implementation conditions of the chlorination method, the fulfilment point and the chlorination method are not described here.
前揭折點加氯法實施時一般僅將氯系氧化劑加入反應槽內之廢污水後，使二者自然產生化學反應，而完成氨氮成份之分解與氮氣之排出，此等化學反應必須花費一段時間，對於廢水處理之效率而言，顯然有待提升。When the pre-extraction point chlorination method is implemented, generally only the chlorine-based oxidant is added to the waste water in the reaction tank, so that the two naturally generate a chemical reaction, and the decomposition of the ammonia-nitrogen component and the discharge of nitrogen are completed, and the chemical reaction must take a period of time. Time, for the efficiency of wastewater treatment, obviously needs to be improved.

該電解裝置14，用以將一化合物電解產生一氧化劑，該化合物係含氫氧化鈉之溶液，如鹽水(或海水)，該氧化劑係次氯酸鈉(NaOCl)，其電解反應之化學式如下：NaCl+H2 O→NaClO+H2 ↑The electrolyzing device 14 is for electrolyzing a compound to produce an oxidizing agent, the compound is a solution containing sodium hydroxide, such as brine (or seawater), and the oxidizing agent is sodium hypochlorite (NaOCl), and the chemical formula of the electrolytic reaction is as follows: NaCl + H 2 O→NaClO+H 2 ↑
該加藥機16，連接該電解裝置14與反應槽12，用以可將該氧化劑(次氯酸鈉)加入反應槽12，使該氧化劑可與廢水進行化學反應(氧化反應)，其加藥量之多寡可利用習知氧化還原電位計來控制。The dosing machine 16 is connected to the electrolysis device 14 and the reaction tank 12 for adding the oxidant (sodium hypochlorite) to the reaction tank 12, so that the oxidant can chemically react with the wastewater (oxidation reaction), and the amount of the oxidant is increased. It can be controlled by a conventional oxidation reduction potentiometer.
該震盪裝置18，係超音波震盪裝置，設置於該反應槽12內，用以可產生振動以加速該氧化劑與廢水之化學 反應，使氨氮成分可於廢水中分解，而生成氮氣、氫氣散逸而出。The oscillating device 18 is an ultrasonic oscillating device disposed in the reaction tank 12 for generating vibration to accelerate the chemistry of the oxidant and waste water. The reaction allows the ammonia nitrogen component to be decomposed in the wastewater to form nitrogen gas and hydrogen gas to escape.
此外，該複合式氨氮廢水處理系統10可更包含有一儲存槽20，係連通該加藥機16，用以可儲存該電解裝置14電解產生之氧化劑並輸送至加藥機16。In addition, the combined ammonia nitrogen wastewater treatment system 10 can further include a storage tank 20 connected to the dosing machine 16 for storing the oxidant generated by the electrolysis device 14 and delivering it to the dosing machine 16.
藉此，本創作該複合式氨氮廢水處理系統10之運作方式及特色、功效如下：欲解決氨氮廢水排放不符合國家廢水標準(放流水標準)之問題，如第二圖所示，可先將含氨氮成份之廢水容納於該反應槽12內，及利用該電解裝置14電解化合物(鹽水)產生之氧化劑(次氯酸鈉)，再以該加藥機16將氧化劑適量地投入反應槽12，繼而啟動該震盪裝置18，使該氧化劑與廢水可受到振動而混合進行化學反應，該氧化劑之添加量以廢水中氨氮成分可完全分解為標準，可視狀況予以調整。該氧化劑與廢水進行化學反應後，氨氮成分可分解而形成氮氣與氫氣冒出廢水，廢水則含有氫氧氯或氫氧化氯而呈酸性，可再添加活性碳等還原劑除氯後排放。Therefore, the operation mode, characteristics and efficacy of the composite ammonia nitrogen wastewater treatment system 10 are as follows: To solve the problem that the ammonia nitrogen wastewater discharge does not meet the national wastewater standard (discharge water standard), as shown in the second figure, The wastewater containing the ammonia nitrogen component is contained in the reaction tank 12, and the oxidizing agent (sodium hypochlorite) produced by electrolyzing the compound (saline) is electrolyzed by the electrolysis device 14, and the oxidizing agent is appropriately introduced into the reaction tank 12 by the dosing machine 16, and then the solution is started. The oscillating device 18 causes the oxidant and the wastewater to be mixed and subjected to a chemical reaction by vibration. The amount of the oxidant added can be completely decomposed into a standard by the ammonia nitrogen component in the wastewater, and can be adjusted depending on the situation. After the oxidant is chemically reacted with the wastewater, the ammonia nitrogen component can be decomposed to form nitrogen and hydrogen to form wastewater, and the wastewater contains hydrochloric acid or chlorine hydroxide to be acidic, and can be discharged by removing a chlorine such as a reducing agent such as activated carbon.

The internal oscillating device vibrates the wastewater, so that the oxidant and the wastewater can rapidly generate a chemical reaction, and the ammonia nitrogen component is decomposed to form nitrogen gas. The hydrogen ejects the waste water. As a result, the wastewater after the chemical reaction does not contain ammonia nitrogen, which can meet the requirements of the national discharge water standard. The ammonia nitrogen wastewater has high treatment efficiency and is of practical value.
