The result showed that the maximum resistance to salinity shock of the three systems above mentioned is in the range of 0~20, 5~30, and 15~35 g/L respectively. When the systems are subject to the shock of salinity, the phenomena such as decrease of organic removal, rising of effluent SS concentration, and washout of lot of sludge will occur. However, when the influent salinity is allowed to return to initial value and is kept stable, the treatment effect of the system can be recovered after enough time.

Saline wastewater was treated by SBR process. Relationships among influent salinity, DO concentration and the course of degradation of organic pollutants were investigated to verify the feasibility of using DO as the control parameter of operation process and reaction time of SBR when saline sewage was treated. The results indicated that during the steady stage the relationship under various salt loading conditions between DO concentration and organic matter degradation was steady and repeatable. According to the relationship, DO concentration can be used as the control parameter of organic matter degradation and predication to reaction can be made so as to control reaction process. However , during the salinity shock stage, there was not steady relationship between DO content and pollutant degradation. Therefore, influent salinity must be kept unvarying to realize using DO as the computer control parameter of SBR process treating saline wastewater.

采用SBR工艺处理含盐生活污水 ,研究了进水的盐度、DO浓度和有机物降解过程三者之间的关系 ,验证以DO作为SBR工艺处理含盐污水有机物降解过程中反应时间和过程控制参数的可行性。分别对经过无机盐驯化稳定运行的活性污泥系统和盐度冲击期间非稳定运行的活性污泥系统进行试验。结果表明 :在稳定运行期间 ,无论进水的盐度变化 ,还是进水的COD或曝气量变化 ,DO和有机物的降解都有很好的相关性。根据这种相关规律可以用DO间接地指示出有机物降解的程度并可以对反应进程进行预测 ,从而实现对反应过程进行控制。但是 ,在盐度冲击期间 ,DO与有机物降解不具有相关性。所以 ,要实现DO作为SBR处理含盐污水的计算机控制参数 ,必须保证盐度的稳定。

Increasing of salinity can lead to the inactivation of microorganisms and deterioration of biotreatment processes.The effects of high salinity on three wastewater biotreatment processes,including one SBR reactor(A) and two contact oxidation processes using sintered fly ash microporous media(B) and microporous glass media(C) respectively,were studied.The results indicated that increasing of NaCl concentration from 0 to 30 gL~(-1) suddenly could lead to 87%,68% and 74% decrease in phenol remove efficiency respectively,and...

Increasing of salinity can lead to the inactivation of microorganisms and deterioration of biotreatment processes.The effects of high salinity on three wastewater biotreatment processes,including one SBR reactor(A) and two contact oxidation processes using sintered fly ash microporous media(B) and microporous glass media(C) respectively,were studied.The results indicated that increasing of NaCl concentration from 0 to 30 gL~(-1) suddenly could lead to 87%,68% and 74% decrease in phenol remove efficiency respectively,and it needs three days for the malfunctional systems to recover to their original states.As acclimated to 30 gL~(-1) NaCl,the three systems can tolerant NaCl concentration up to 70 gL~(-1).With salt concentration changing from 0 to 150 gL~(-1) biodegradation of phenol in all the three systems fitted zero- order-reaction with respect to the phenol concentration very well.As for phenol degradation rate,system B performed better to the increase of salinity than the other two,and the SBR reactor was most sensitive to the change of salinity.

高含盐废水能使常规生物处理系统处理性能下降、甚至崩溃.以苯酚为基质,对SBR处理系统(A)以及两种接触氧化处理系统B、C(其中B使用自制粉煤灰微孔填料,C使用自制微孔玻璃填料)抗盐度冲击能力的研究表明,盐度突然升高到3%会使A,B,C三种系统的苯酚去除率分别下降87%,68%和74%;但短时间内三种系统都能恢复到加盐前的处理水平.以降解速率变化为依据,使用微孔填料的B,C处理系统抗盐度冲击能力大于A系统,且B,C系统出水平均浊度低于5NTU.在NaCl含量0~150g.L-1下,苯酚生物降解速率对苯酚浓度均为0级反应,适当延长水力停留时间可以使苯酚完全去除.
