Application of Ozone-Activated Carbon Process in Upgrading and Reconstruction of a WTP in Dongying
In order to improve water quality,a water treatment plant(WTP)in Kenli District,Dongying City needs to upgrade the current WTP.The total scale of the WTP is 60 000 m3/d.The metric ton water land index of the proposed plot is low,and the effluent water quality is less than 0.5 NTU based on the requirement of Standards for Drinking Water Quality(GB 5749-2022).This paper summarizes the comparison and formulation of the upgrading and reconstruction of the treatment process of the WTP,and introduces the design and application of ozone-activated carbon process in this project in detail.The operation of ozone-activated carbon advanced treatment technology in this WTP can improve the sensory indices such as chrominance,smell and taste of water,and improve the guarantee rate of aerobic indices such as ammonia nitrogen,nitrite and organic halide.Especially when the water quality deteriorates in summer and the water source contains large amount of mud,it can guarantee the stability of effluent water quality and ensure the safety of urban water supply.
