摘要
采用鱼品加工厂生产废水掺一定比例的海水作为试验用水,通过含盐量的不断增加研究系统的耐盐性,通过含盐量的降低和升高研究系统的抗盐度波动性。试验表明,当Cl-的质量浓度<6300mg/L时,CASS系统可正常运行;当Cl-的质量浓度<4500mg/L时,对于Cl-质量浓度梯度为3600mg/L的冲击,系统可以在1个运行周期内恢复正常运行。
Wastewater from the production of marine products processing plant and sea water,which are mixed at certain ratio,were used as the water for the test.The salt fastness of the system was studied through the increasing of salt content,and the fluctuation of the salt fastness of the system was studied through the increase and decrease of salt content.It was shown by the test that when the mass concentration of Cl - was<6300mg/L,the CASS system worked normally;when the mass concentration of Cl - was<4500mg/L and the impact by the Cl - mass concentration gradient was3600mg/L,the system restored its normal operation within one operating cycle.
