Abstract

A találmány tárgya szennyvíztisztító egység, amely legalább egybiológiai szennyvízkezeléssel működő eleven iszapos medencével éslegalább egy, az eleven iszapos medencében vagy azon kívülelhelyezett, lényegében tölcsér alakú utóülepítő medencével, melybenszilárd anyagok és az azokhoz kötődő mikroorganizmusok ülepednek le,melyek az utóülepítő medencéből az eleven iszapos medencébevisszavezetendők. A megoldás jellegzetessége, hogy egy lényegében üresközponti hengert (3) tartalmaz, amely kisebb átmérővel bír, mint alefele szűkülő utóülepítő medence (2) a fenéken és a központi hengerezen kívül az utóülepítő medence fenekéről történő iszapeltávolításcéljából berendezéseket (5, 6) tartalmaz. A találmány szerintiszennyvizek tisztítására szolgáló eljárás pedig azon az elvenalapszik, hogy a tisztított szennyvíz a legalább egy utóülepítőmedencéből elszívásra kerül, továbbá az utóülepítő medencébenleülepedő iszapot eltávolítják és az eleveniszapos medencébe vezetik,valamint az eleveniszapos medence alján az ürítőkamra egy vezetékenkeresztül az oszlop belső terével össze van kötve és ennek felsőrészébe csatlakozik úgy, hogy a külső szennyvíz-hozzávezetés és aziszap-visszavezetés következtében az eleven iszapos medencébenmegemelkedő vízszint hidrosztatikai nyomás révén az ürítő kamrából azoszlopba szennyvizet nyom, amint a szennyvízszint az eleven iszaposmedencében az összekötő vezeték oszlopba csatlakozásának magasságátmeghaladja. ÓThe subject of the invention is a wastewater treatment unit with at least one activated sludge pool operating with biological wastewater treatment and at least one essentially funnel-shaped secondary sedimentation basin located in or outside the activated sludge basin, in which non-solid materials and the microorganisms associated with them settle, which are to be returned from the secondary sedimentation basin to the activated sludge basin. The characteristic of the solution is that it contains an essentially empty central cylinder (3), which has a smaller diameter than the downwardly narrowing post-settling basin (2), and in addition to the central cylinder, it contains devices (5, 6) for the purpose of removing sludge from the bottom of the post-settling basin. The method for cleaning waste water according to the invention is based on the principle that the purified waste water is extracted from at least one post-sedimentation basin, and the sludge that settles in the post-sedimentation basin is removed and led to the activated sludge basin, as well as the emptying chamber at the bottom of the activated sludge basin is connected to the interior of the column via a pipe and it is connected to the upper part of it in such a way that the rising water level in the activated sludge pool as a result of the external sewage supply and sludge return pushes sewage from the discharge chamber into the azo column through hydrostatic pressure, as soon as the sewage level in the activated sludge pool exceeds the height of the connection of the connecting line to the column.
