摘要
近几年来,随着我国经济的迅猛发展,对环境所造成的污染也不断加剧。因此,有必要采取有效的措施对废水进行处理,保护生态环境和人类健康。
     本研究课题较全面的介绍了天津蓟县经济开发区污水处理厂——本课题依托工程,较深入的研究了SBR工艺处理废水过程中有机底物的降解规律。通过对该污水处理厂的运行效率、工艺机理、影响因素等的分析,证明该方案具有工艺先进、技术可行、经济合理等优点,出水水质稳定且能达到《城镇污水处理厂污染物排放标准》(GB18918-2002)的二级排放标准。
     以格栅、曝气沉砂池和气浮池作为整个废水处理流程的预处理单元,目的在于去除废水中较大的砂子、悬浮物和动植物油。
     SBR作为核心处理单元,依靠系统内活性污泥的吸附和代谢作用进一步去除废水中的有机负荷及前处理单元中残余的胶体和悬浮物质。本课题从SBR生化系统的启动到正常运行,对系统内微生物的种类与活性、系统的环境(pH、DO、温度、营养物等)等因素进行了研究。对调试和运行中出现的问题进行了重点研究,采取了一定的措施加快了活性污泥的培养与驯化,根据实际情况合理调整SBR池的运行工况,经过一个多月的调试,系统转入了正常运行。
     根据Monod方程进行了SBR工艺处理废水的动力学分析,建立并推导了适用于该工艺基质降解的数学模型,验证了SBR反应器中CODCr的降解过程较好地服从一级反应动力学关系式,并得到了适于该水质的动力学参数,从而定量地描述了有机底物降解规律及活性污泥增长规律。
     该工艺实际运行和技术经济分析结果表明,其处理效果较好、运行稳定、抗冲击负荷能力强,基建投资和运行费用相对都较低,与同类废水其它生化法处理工艺比较,具有较大的优势。该工艺固定资产投资为700万元,实际运行费用仅为0.62元/m3,是一种技术可行、经济合理的废水处理方法。
In recent years, environment pollution is becoming more serious with the economic development .So it is necessary to take effective measures to treat the wastewater and protect the ecosystem environment and human health.
     In this paper, the wastewater treatment plant of Jixian economic technology development zone in Tianjin——the engineering this thesis concerns is presented comprehensively. Degradation law of organic substance in the treatment process of wastewater by sequencing batch reactor is studied deeply. The analysis about waste- water treatment plant on operation efficiency, reaction mechanism and influence factors indicate that this process is advanced, economical and feasible. The effluent is stable and can meet the Discharge Standard of pollutants for municipal wastewater treatment plant of GB18918-2002.
     The grille, aeration settlement tank and air-striping tank are used as pretreatment unit in all process, aiming to remove sand , suspended material and animal-plant oil.
     As a key unit ,SBR can further eliminate the organic load of the wastewater and also the colloid and suspend substance through the adsorption and metabolism of the active sludge. From the start to the normal operation of the SBR system, this paper researches the species and activity of the microbios in the system. At meantime, the factors , such as pH, DO, temperature, and nutrition etc., are researched too. The problems arising in the preliminary testing and run are researched , and some measures are also taken to speed up the cultivation of active sludge and adjust the operating mode according to the real condition. After the operation of more than a month , the system runs normally.
     Kinetic analysis of industrial wastewater by sequencing batch reactor is developed on the basis of Monod model. The mathematic model of SBR treatment system strictly obeys the first-order kinetics relation under the condition of experimental concentration. Experimental results are consistent with the model and kinetic parameters fitting for the water quality were obtained. Therefore, regulations of organic substance degradation and activated sludge growth become available.
     The wonderful effect of treatment, stable run ,strong resistant to organic load and the low of capital construction and the cost of run show that the process has an advantage over other process viewing from the run and economical analysis. The fixed property cost of the process is 7,000,000 yuan and the operation cost is 0.62 yuan /m3. All of these show that the SBR process is a suitable way to treat the wastewater, both in the point of feasibility of technology and economical.
