    To avoid considerable vertical and horizontal flows in the settler formed by gas collection hoods, of the upflow anaerobic sludge blanket (U.A.S.B.) reactor, each gas collection hood (3) debouches at one or two ends into a gas collection chamber (8) via one or more openings (19), the upper boundary of said openings being situated below the inside surface of the projection or the top of the hood (3) concerned. The gas collection hoods are situated immediately below the level of the effluent discharge and the depth of the settler is shallow. As a result of the decrease in pressure only a few gas bubbles are consequently liberated and the settling of the sludge is not appreciably disturbed.

    This invention relates to anaerobic wastewater treatment.
    The purpose of the invention is to increase the cleaning efficiency by preventing the formation of vertical and horizontal flows in the sump.
    FIG. 3 shows the installation, longitudinal section in FIG. 2 - section A-A in FIG. 1; in fig. 3 - a gas collection cap with a gas collection chamber. The installation comprises a reactor 1, the lower part of which forms a section 2 of fermentation, on which is placed a settling tank formed by gas collecting caps 3 next to each other,
    Above the upper row of caps are 3 polos; ken are a series of overflow gutters 4 with Y-shaped notches 5 in the side. walls. These discharge channels are intended for collecting purified water. Each overflow chute 4 is provided with a pipe 6 connected to a collection pipe 7 of discharge.
    Each gas collection cap 3 is connected at one end to the gas collection chamber 8, which is connected to a pipe 9 o. At the connection point of the gas collection cap 3, a small receiver 10 is provided, consisting of a solid front wall 11, a continuous side wall.12 and a base 13. Rear tee the upper surfaces of the small receivers 10 are open or provided with openings 14, while the upper edge of the 15-front wall 11 is located above the upper edge of the openings L 4 s
    Supply pipe 16 for wastewater is connected to section 2 of the fermentation.
    The installation works as follows.
    The anaerobic sludge layer is placed on the bottom of the fermentation section 2. Wastewater is supplied through conduit 16 and distributed along the bottom of the reactor 1 by known means (not shown). By the result of anaerobic fermentation, the organic material is converted into a fermentation gas (methane), which partially dissolves in water and partially rises as gas bubbles. The fluid level rises due to the exit of the flow stream supplied until this level reaches the upper edge of the overflow troughs 4 - and

    these troughs are filled with a stream of purified water. Purified water is removed through pipes 6 and 7.
    The rising gas is collected in the gas collecting cap 3 and from the caps through the open top surface and the open back surface of the small receivers 10 enters the gas collecting chamber 8 and is removed from it through the pipe 9. Since the top edge 15 of the front wall 11 is above the top edge of the holes 14 in the rear the wall of the receivers 10, the liquid cannot get into the gas collecting chamber 8s because the gas pressure in each cap 3 displaces the liquid back below the level of the upper edge 15 of the front wall 11J after which the gas enters the chamber 8, the gas pressure goes - derzhivaets on virtually constant level, which level is sufficient to hold Jew bone below the edges 15o receivers actually play the role of a lock against flow of liquid in the gas gathering chamber 8 '
    Other constructions, such as pressure-sensitive non-return valves, or valves controlled by the water level can be used as such valves. When using small receivers 10, because of their simplicity and reliability of operation, a different arrangement of gas openings is allowed. For example, the upper part of the receivers is closed and one or several openings-sh are located in the front wall 11. In a blender. An open rear wall of the receptacle can be used in a series of holes in the solid rear wall. However, the overflow edge of the holes in the front wall must be higher than the upper edge of the holes in the rear wall.
    Instead of a common gas collecting chamber 8, each cap may have its own gas outlet.
