【考案の詳細な説明】 産業上の利用分野 本考案は汚水浄化装置に関し、特には河川に放流される
排水を活性化することによって微生物による浄化作用を
促進することができる装置に関するものである。TECHNICAL FIELD The present invention relates to a sewage purification apparatus, and more particularly to a sewage purification apparatus that can promote purification by microorganisms by activating wastewater discharged into a river.

化装置であることが望ましい。Conventional technology Conventionally, if industrial wastewater generated from corporate facilities and domestic wastewater generated from each household are directly discharged into a river, the river and groundwater will be contaminated and the local environment will be deteriorated. It is customary to purify with a device before discharging. Especially in recent years, the improvement of rivers has progressed, the self-cleaning action of the river itself has weakened, and the pollution of water quality has become a problem with the population increase and economic development in the river basin. It is desirable that the purification device not only purifies but also promotes the self-cleaning action of the river after discharge.

果がある。Further, since the treated water flow passage is formed on the side of the porous contact material filled in the contact aeration tank, and a plurality of diffuser pipes are arranged below, the circulating flow of the treated water in the contact aeration tank. Are formed, and the sewage can be activated based on the chemical action at the time of collision between the treated water and the contact material. Further, the bubbles ejected from the air diffuser rise in the contact material through various paths, so that the sludge adhering to the inside of the contact material is separated and clogging of the contact material is prevented. Further, the air jetted from the air diffuser has an effect of generating a swirling flow of the treated water and preventing a short circuit of the treated water in the contact aeration tank and anaerobicization due to this short circuit.

更に接触材の持つ多孔性によって水中での気泡の滞留時
