摘要:针对规模化畜禽养殖废水常规厌氧-好氧组合处理工艺及SBR处理工艺脱氮效率低、运行费用高等问题,采用UASB-SBR工艺,研究3种不同的SBR模式对处理效果的影响。结果表明,UASB容积负荷(以COD计)8 kg·(m3·d)-1、pH 7.0、温度35 ℃、HRT 25 h时,COD去除率为80%~85%;SBR在进水15 min、反应480 min、沉淀60 min、出水15 min、闲置810 min条件下,对废水COD、NH+4-N、和TN去除率分别为91.8%、98.7%和71.6%,出水COD≤180 mg·L-1、NH+4-N2-N积累率超过50%,出现了NO-2-N积累,短程硝化反硝化是主要脱氮方式。

Abstract:In this paper, a treatment process of UASB-SBR was built to treat the large scale livestock wastewater, which aimed to solve the problem of conventional anaerobic-aerobic treatment process and SBR treatment process including low denification efficiency, high operating costs and so on. Based on the treatment process, three kinds of SBR experiment were studied. It can be seen from the experiment that when the volume loading(calculated by COD) was 8 kg·(m3·d)-1, with the pH value of 7,the temperature of 35 ℃ and HRT of 25 h, the removal efficiency of COD was from 80% to 85% during the anaerobic process (UASB). For the optimized SBR treatment conditions (influent 15 min, reaction 480 min, precipitation 60 min, effluent 15 min, idle 810 min), the removal efficiency of COD,NH+4-N and TN in livestock wastewater in SBR were 91.8%,98.7% and 71.6%, respectively. The effluent COD was less than 180 mg·L-1, NH+4-N<15 mg·L-1, TN<50 mg·L-1, meeting the Discharge Standard of Pollutants for Livestock and Poultry Breeding(GB 18596-2001). The nitrite accumulation occurred and shortcut nitrification denitrification was the main way of nitrogen removal.
