【摘要】：隨著經(jīng)濟的發(fā)展與人們生活水平的不斷提高,人們對水資源的需求與排放量也逐漸增大,對水體的污染也越來越嚴(yán)重。分散式生活污水有效處理回用,不僅可以有效解決排放污染問題,而且可以解決部分用水問題,具有良好的開發(fā)前景。目前,中水處理技術(shù)尚未成熟,而現(xiàn)有的污水處理技術(shù)又難以達到污水資源化的要求。因此,本文針對分散式生活污水的排放特點,主要采用以環(huán)境友好型技術(shù)著稱的電化學(xué)法方法進行處理,目的是利用該技術(shù)簡化傳統(tǒng)污水處理工藝,并達到快速便捷處理以滿足回用的目的。本文主要以污水中的有機物、氮和磷的降解或去除為重點目標(biāo),根據(jù)電化學(xué)水處理的特點及反應(yīng)機理,探究電化學(xué)處理過程的影響規(guī)律與最佳反應(yīng)條件。研究表明,電化學(xué)對污水具有較好的處理效果,可以實現(xiàn)分散式污水回用處理的目的。電化學(xué)處理對磷的處理效果非常高,電解時間與電壓對總磷均有影響,隨著電解時間的延長,TP的去除量增加,當(dāng)電壓為5V時,在30min內(nèi)完成對磷的全部去除。該工藝對水體中COD具有較好的去除效果。其中,陰極材料、電極間距、電壓、氯離子以及添加劑Fe3O4對COD的去除效果均有影響。極板間距的縮進有利于COD的去除。適量氯離子可促進污染物的降解,提高COD的去除率。Fe3O4的添加有助于促進COD的去除。當(dāng)Fe3O4的投加量為80mg/L時,作用時間為30min,COD的去除率可達70%,滿足回用的目的要求。電化學(xué)對氨氮的去除效果有限,氯離子的添加可促進氨氮的去除。實驗結(jié)果表明,當(dāng)電壓為8V,間距為15mm,Fe3O4和電解質(zhì)NaCl投加量分別為50mg/L和5000mg/L,處理后的城鎮(zhèn)生活污水可滿足生活雜用水回用要求。
[Abstract]:With the development of economy and the improvement of people's living standard, the demand and discharge of water resources are increasing, and the pollution of water is becoming more and more serious. It can not only effectively solve the problem of discharge pollution, but also solve part of the problem of water use, which has a good prospect of development. At present, the technology of reclaimed water treatment is not mature. However, the existing sewage treatment technology is difficult to meet the requirements of wastewater reuse. Therefore, according to the characteristics of decentralized domestic sewage discharge, this paper mainly adopts the electrochemical method, which is famous for environment-friendly technology. The purpose of this paper is to simplify the traditional wastewater treatment process and to achieve rapid and convenient treatment to meet the purpose of reuse. This paper focuses on the degradation or removal of organic matter, nitrogen and phosphorus in sewage. According to the characteristics and reaction mechanism of electrochemical water treatment, the influence law and optimum reaction conditions of electrochemical treatment process were studied. The effect of electrochemical treatment on phosphorus treatment is very high. The electrolysis time and voltage have an effect on total phosphorus. With the increase of electrolytic time, the removal of TP increases, when the voltage is 5 V, All phosphorus removal was completed in 30 minutes. The process has a good removal effect on COD in water. Among them, cathode material, electrode spacing, voltage, Chlorine ions and additive Fe3O4 have an effect on the removal of COD. The reduction of plate spacing is beneficial to the removal of COD, and the proper amount of chloride ions can promote the degradation of pollutants. When the dosage of Fe3O4 is 80 mg / L, the removal rate of COD in 30 mins can reach 70%, which can meet the requirements of reuse. The electrochemical removal effect of ammonia nitrogen is limited, and the effect of electrochemistry on the removal of ammonia nitrogen is limited when the dosage of Fe3O4 is 80 mg / L, and the removal rate of COD can be increased by increasing the removal rate of Fe3O4.When the dosage of Fe3O4 is 80 mg / L. The experimental results show that when the voltage is 8V, the spacing is 15mm NaCl and the dosage of electrolyte NaCl is 50mg / L and 5000mg / L respectively, the treated municipal domestic sewage can meet the requirements of domestic miscellaneous water reuse.
