在运用LTBR工艺处理石化行业碱渣废水的过程中,由于碱渣废水的高浓度特性以及LTBR工艺高负荷的特点,在外界气温较高时,LTBR生物反应器运行温度常常会达到40℃以上,严重影响了碱渣废水处理装置的平稳运行,极大限制了装置的处理能力,为了解决这一瓶颈问题,在LTBR工艺中引进了换热系统,成功地消除了反应器大幅温升带来的影响,同时使处理装置的运行更加平稳、高效,并为LTBR工艺在其他高浓度废水处理领域的推广创造了必要条件。
In the process of using LTBR process to treat the alkaline waste water in the petrochemical industry, the operating temperature of the LTBR bioreactor often reaches above 40 ° C due to the high concentration characteristics of the alkaline waste water and the high load of the LTBR process when the outside air temperature is high, Seriously affecting the smooth operation of the caustic wastewater treatment plant, which greatly limits the handling capacity of the plant. In order to solve this bottleneck problem, a heat exchange system was introduced into the LTBR process to successfully eliminate the reactor temperature increase Influence, at the same time make the operation of the treatment device more stable and efficient, and create the necessary conditions for the promotion of the LTBR process in the field of other high-concentration wastewater treatment.
