Abstract
Focusing on the characteristics of inorganic wastewater produced in railway tunnel construction and the disadvantages of the existing treatment process,the horizontal tube solid-liquid separation device was used to test the pollutant removal efficiency in this study.It was shown a good removal efficiency under the conditions of oxalic acid average dosage 158.24 mg/L,PAC(active ingredient 5%)average dosage 57.30 mg/L,PAM(active ingredient 0.1%)average dosage 0.54 mg/L.The removal efficiency of suspended solids by wastewater treatment equipment was 89.38%~99.37%,and the average pH value of effluent was 7.99.The effluent SS and pH reached the limitation of The Reuse of Urban Recycling Water Quality Standard for Urban Miscellaneous Use(GB/T 18920-2020).关键词
