摘要： Aerobic purification of waste water with intermittent batchwise supply of waste water to the activated sludge tank from which the treated waste water drains continuously is disclosed, in which the nitrate content in the waste water is simultaneously reduced by throttling the aeration of the activated sludge tank, starting with the admission of the waste water to the tank, to values equivalent to less than or equal to 0.5 mg/l dissolved oxygen. In particular, aeration may be off until such time as the nitrate content in the tank has dropped below 5 mg/l, in particular below 1 mg/l. In the case of urban waste waters a cycle time of about 1 hour is expediently employed under these circumstances and the aeration is shut off for about 5 minutes, starting from the rapid admission of the waste water charge. Preferably, inlet charges are less than or equal to 30%, in particular between about 5% and 20%, of the tank capacity. In this procedure, nitrate present is degraded in the phase involving oxygen throttling, while in the subsequent phase (over longer times) ammonium fed in with the waste water supplied is converted into nitrate, provision being made for a sufficient population of nitrifying bacteria in the tank.

摘要： A plant suitable, in particular, for denitrifying sewage purification by the activated sludge process comprises several tanks which are charged with untreated water via a common delivery conduit which is preferably designed as a ring main. This delivery conduit, which is arranged above the maximum water level in the tanks, has an essentially horizontal course and serves as storage space for the sewage feed to the individual tanks via rapid-closing and -opening gate valves for spontaneous or gravitational emptying into the particular tank. The delivery conduit is preferably designed as a closed double channel with a lower discharge conduit, which is located below the minimum water level in the tanks, for discharging the sludge/water mixture to the final clarification tank. It is expedient to include an operation bridge or walkway with the delivery conduit.

摘要： Purification of liquid agricultural wastes, such as, in particular, liquidanure, by means of an algae/bacteria mixture culture and a subsequent rotifer culture in a separate stage. The pH-value of the algae/bacteria mixture culture is controlled, especially by the waste water charging thereof, in such a way that a multiplication of rotifers in this stage is inhibited or precluded. The algae/bacteria mixture culture preferably occurs in shallow open air ponds for a period of time which depends upon the temperature and can amount to three to six days at a mean temperature of approximately 18.degree. C. The hold time of the algae/bacteria suspension which is in the rotifer container and is adjusted to a pH of 6 to 8 can range from two to four days at a temperature of approximately 20.degree. C. A waste water treatment plant or system for the foregoing includes at least one algae/bacteria mixture culture reservior and at least one rotifer reactor.
