[[alternative]]Feasibility Evaluation of High Alkali Water Used in Sewage Treatment

[[abstract]] 為確保防治水源被不肖業者污染，為保護水源環境生態，改善人類生活環境，增進國民健康，工業區或非工業區廠商，排放廢 (污) 水於地面水體者，應符合放流水標準。污水廠為處理工廠類別產生之廢水，加上環保法規國家放流水水質管控加嚴，若能將廢水處理成本降低，氨氮、化學需氧量及重金屬濃度降低處理為污水處理廠目前最急尋降低加藥成本，可有效增加污水處理廠的效益，目前國內污水廠使用NAOH調整廢污水的酸鹼質及去除重金屬的藥劑，降低藥劑處理費方法紛紛出現。 本研究利用將純淨原水，使用直流電進行電氣分解，在兩槽電極版增加電壓電流，電極兩端會將水表面分子分解，在負電極板端產生氫氧化離子(OH-)，正離子及水容氫會增加，而製造出酸鹼值高pH值的水，當H+濃度小於OH-水液呈鹼性，稱為高鹼水。高鹼度離子水加入廢污水以提高廢污水酸鹼值，在酸鹼值9.0的廢水中離子水OH基與氨氮及銅反應結合後以達去除效果。因此降低廢水汙染物質濃度，使水質達到國家放流水水質標準。[[abstract]] In order to ensure the prevention and control of water pollution by unscrupulous operators, and to protect the environment of the water source, improve human living environment, and improve national health, manufacturers in industrial or non-industrial areas who discharge waste (sewage) water to surface water bodies should meet the standards of discharge water. Sewage plants are the treatment of waste water generated by the types of plants. In addition, environmental protection laws and regulations of national discharge water quality are tightened. If wastewater treatment costs can be reduced, ammonia nitrogen, chemical oxygen demand, and heavy metal concentration reduction are the most urgently sought reductions in sewage treatment plants. The cost of dosing can effectively increase the efficiency of the sewage treatment plant. At present, domestic sewage plants use NAOH to adjust the acidity and alkalinity of the waste water and the reagents to remove heavy metals. In this study, the pure raw water was decomposed using direct current to increase the voltage and current in the two-slot electrode plate. The molecules on the surface of the water will be decomposed at both ends of the electrode, and hydroxide ions (OH-), positive ions and water will be generated at the end of the negative electrode plate. Hydrogen capacity will increase, and the water with high pH value is made, when the H + concentration is less than OH- water, the liquid is alkaline, called high alkali water. High alkalinity ionized water is added to the waste water to increase the pH value of the waste water. In the wastewater with a pH value of 9.0, the ionized water OH group reacts with the ammonia nitrogen and copper to achieve the removal effect. Therefore, the concentration of pollutants in waste water is reduced, so that the water quality meets the national discharge water quality standards
