PROBLEM TO BE SOLVED: To provide a liquid treatment column which can efficiently discharge liquid to be treated and improve the efficiency of washing operation by a simple configuration.SOLUTION: A liquid treatment column includes a column body, an inflow part which is formed in the upper part of the column body and through which liquid to be treated is supplied, and a perforated plate which has a plurality of through holes and is arranged in the lower part of the column body. The liquid to be treated supplied through the inflow part is treated by a liquid treatment agent filled on the perforated plate and discharged through the plurality of through holes. The liquid treatment column has a plurality of liquid collecting pipes extending downward from the plurality of through holes. In the liquid treatment column, the plurality of liquid collecting pipes preferably have the same length and internal diameter. Support means is preferably further provided which supports the perforated plate. The support means preferably have a plurality of support parts which are arranged in a lattice form in a plan view to support the perforated plate from below. |
