摘要： PROBLEM TO BE SOLVED: To stably and continuously measure the pH of ammonia liquor without stopping, and overhauling/inspecting a pH meter.SOLUTION: An ammonia liquor treatment system 1 includes: an ammonia stripper 11 which removes ammonia contained in ammonia liquor that has been discharged from a coke oven; biological treatment equipment 15 which subjects a part of the ammonia liquor that has been discharged from the ammonia stripper 11 to biological treatment; a heat exchanger 12 which cools the other part of the ammonia liquor that has been discharged from the ammonia stripper 11; a liquid cyclone 13 which subjects the ammonia liquor that has been cooled by the heat exchanger 12 to oil-water separation treatment; and a pH meter 14 which measures the pH of moisture that has been obtained by the oil-water separation treatment. The pH meter 14 has a washing mechanism 14a which washes a detection end of pH.
