    This invention relates to anaerobic wastewater treatment.
    The purpose of the invention is to increase the degree of separation of sediment and water and eliminate turbulence near the release of treated water.
    Fig, 1 shows the proposed installation, a longitudinal section; in fig. 2 - the same cross section
    The installation contains a cylindrical tank 1, in the upper part of which there is a sump, formed by caps located on three levels for collecting gas: caps 2 on the lower level, caps 3 on the middle level and caps 4 on the upper level Each cap 4 of the upper level is located directly above the cap 2 of the lower level. Caps 2 lower level overlap caps 3 average level.
    Caps, for collecting gas, are supported by a system of supports 5, cross-beams 6 and bearing intersecting beams 7,
    On top of this, tank 1 is covered with a system of elongated plastic caps 8 and grooves 9. This system rests on intersecting support beams 7. The installation also contains system 10 for supplying and distributing source waves. Between caps 3 and 4 for collecting gas, there are overflow channels 11 for purified water, connected by connecting pipes 12 with main outlets 13 and 14.
    Caps 3 and 4 for collecting gas of the middle and upper levels, respectively, are directly connected to the main pipe 15 for gas release and the pipe 16 leading, for example, to a gas meter. The lower cap 2 is also connected by a pipe 17 to the upper cap 4. The installation contains limiters in the form of inclined guide plates 18 and guide plates 19,
    The installation works as follows.
    Anaerobic sludge bed is located
    at the bottom of the tank 1. Wastewater
    are fed into the reservoir through the feed system 10, ensuring good distribution. As a result of anaerobic fermentation, the organic material is converted to methane, which is partially dissolved in water, and partially rises in the form of gas bubbles. As the wastewater flows, the water level rises until

    will not reach the edge of the overflow channels 11. The purified water passes into the indicated channels and is released through the connecting pipes 12 and pipes 13 and 14. The rising gas is collected in caps 2, 3 and 4 to collect the gas. From caps 3 and 4, gas passes directly into pipe 15 for gas release, and from lower caps 2 through gas pipes 17 gas enters upper caps 4, from where it passes into pipe 15 for gas release.
    The release of gas through pipe 15 is regulated so that the level of liquid in caps 3 and 4 is lower than the general level of liquid, determined by the height of the overflow channels 11. rbulent motion in them.
    Since the bases of the pipes 17 have stoppers in the form of inclined guides to the cich plates 18, sediment in the pipes the sediment can flow down along the guide plates 18 back to the fermentation zone. The essential condition is the absence of turbulence in the flow of water passing to the overflow channels. Only in this case can a satisfactory separation of the purified water from the sludge particles contained in it be ensured. The sludge sedimentation process is completed on the upper surfaces of caps 2, 3 and 4 to collect the gas, after which the sediment slides down on these surfaces down to the fermentation chamber located under the septic tank.
    The presence in the sump of three levels of gas collection caps makes it possible to avoid turbulence in the flow of water. Upper caps serve to collect the gas released as a result of the surplus and to avoid turbulence caused by small gas bubbles entering the deposition zone. Inside the pipes 17, a circulating flow is created, t, e. ascending gas-containing flow and descending, gas-free flow of water and sludge. Such circulation is limited by the tube 17 due to the fact that they protrude above the liquid level. If a floating layer is formed inside the caps A, it can be: broken down by lowering the gas pressure at which
    the liquid level rises above the upper ends of the pipes 17.
    The sump is formed by direct caps for collecting gas. In small reactors, round concentric caps can be used. The linear caps are extended to the edge that passes around the circumference of the tank. This means that the surface of the guide plates installed next to the settling tank inside the tank can be limited to a minimum size. These shields transmit gas in a horizontal direction, while horizontal flows disturb the sediment. In addition, the deposition surface area is increased in the reactor, the gas and hydraulic loads are reduced, which allows for an increase in the maximum load of the reactor.
