摘要

The putrefying tank construction in a water basin, comprises lower part made in the form of polygon shaped L-stones which have put together, an upper part that is conically shaped on the upper side for the purpose of absorbing the generated bio-gas, and an overflow slot provided between the upper and lower part, so that between both these parts, waste water can flow. Analogous to this construction, a row of hole shaped openings in a continuous, container construction made out of one part can be put into use. The putrefying tank construction in a water basin, comprises lower part made in the form of polygon shaped L-stones that are put together, an upper part that is conically shaped on the upper side for the purpose of absorbing the generated bio-gas, and an overflow slot provided between the upper and the lower part, so that between both these parts, waste water can flow. Analogous to this construction, a row of hole shaped openings in a continuous, container construction made out of one part can be put into use. In the existing water basins (for example inoperative clarifiers, waste water ponds or similar ones), which are filled with waste water, a putrefying tank is used (if necessary a water tank for other purposes), which has only a limited stability due to the outer water pressure, to keep the water or the waste water inner pressure. According to need, in cold climates, the Putrefying tank can be made of two wall parts with an inner lying isolation. The upper part is made from steel or glass reinforced-plastic material. The lower part of the putrefying tank is made out of a thin concrete ring or (when the diameter of the tank is huge) is made up of steel or plastic walls. The tank shape can be enhanced also by a bottom-lying cone.
