本発明は波動床式汚水処理袋Ｗｔ由の担体に関するもの
である。[Detailed Description of the Invention] (Industrial Field) The present invention relates to a carrier derived from a wave bed type sewage treatment bag Wt.

す。(Prior art and its problems) The conventional fluidized bed sewage treatment equipment has a vertical main body 1 (11) with granular carriers 10 inside, as shown in FIGS. 3 and 4.
2 is charged, and the carrier 102 is made to flow with an upward flow formed by introducing wastewater IU 3 and circulating water 104 from the lower part of the main body]01, and the organisms-105 generated on the surface of the carrier 102 are The mechanism is such that the waste water is treated by the movement of the water, and treated water 106 is obtained. A part of the treated water 106 becomes circulating water 04. 107 and 108 indicate pumps.

恐れがある。As the fingers 102 of such a fluidized bed type sewage treatment bag U, if-1 sand with a grain size of 035 to 1 is usually used, or in order to fluidize it, a large circulation flow test is required. The energy consumption of the pump 108 for this purpose is large. In order to save energy, it is necessary to select K to reduce the circulating water flow, h' to reduce the grain size of the carrier, or a carrier that can flow at a low upward flow velocity by reducing the specific gravity of the carrier. However, if the particle size of the carrier is made small, drifting tends to occur, and if the particle size of the carrier is small,
If a thick carrier is used, there is a risk of soil pollution due to the outflow of carrier fragments.
斐に、流入汚水中に多量の懇瀾物實が含まれている場合
は、その相当部分が指体の層を通過して処理水１（Ｉ６
中に流出して処理を悪化させる可能性が強い。However, if the inflowing sewage contains a large amount of waste material, a considerable portion of it passes through the finger body layer and enters the treated water 1 (I6).
There is a strong possibility that it will leak inside and worsen the process.

Either soak the entire carrier including the inside in water before charging it, or after charging, the gas phase inside the main body, and therefore the gas phase inside the carrier, can be soaked in water such as water, carbon dioxide, etc. As water vapor returns to water by exchanging gas phase K [which is easy to dissipate], or as carbon dioxide or the like dissolves into water, the inside of the phase becomes under pressure and water enters.
