摘要： The present invention has an object to provide a biomembrane filtration apparatus which can treat a nitrate nitrogen and nitrite nitrogen in an anaerobic state to stably remove them together with SS with efficiency and, simultaneously, can biologically remove the residual hydrogen donor as well remaining in the water to be treated in one and the same biomembrane filtration apparatus by a fixed bed biomembrane filtration method and a method therefor. As the means to achieve such an object, one embodiment of the present invention provides a biomembrane filtration apparatus having a packed layer packed with a particulate packing material to which microorganisms are to attach; an inlet for a liquid to be treated arranged above the packed layer to feed the liquid to be treated; and a gas feed opening arranged under the packed layer to feed a substantially oxygen-free gas or a gas containing trace amounts of oxygen.

摘要： In a system for separating crystals from sludge, or from separated water generated in a sludge concentration process or a dewatering process, both phosphorus removal and phosphorus recovery can be satisfactorily achieved, and MAP having a high degree of purity can be recovered. Also, stable treatment can be performed such that the MAP recovery rate is high and blocking of a liquid cyclone do not occur. An aspect of the present invention is a crystal separation apparatus for separating crystals from sludge, or from separated water generated in a sludgeconcentration process or a dewatering process, comprising a liquid cyclone for separating the crystals from the sludge or separated water introduced into the liquid cyclone, and a return pipe A for returning an overflow from the liquid cyclone to a supplying portion of said sludge or said separated water.
