摘要： The invention relates to a method and an apparatus for treating and/or pre- treating liquid manure or biogas plant reject for eliminating harmful substances, particularly nitrogen, phosphorus, and odor molecules. Process tanks (5), which include inlet means (4) for supplying a process tank (5) with a substance to be treated, outlet means for passing a post-treatment matter out of the tank, and air inlet means (2) for supplying the process tank with air required by a biological process, are used for conducting a biological treatment on the matter to be treated. The process tanks (5) are first provided with a microbe population adapted for treating the matter to be treated. The matter to be treated is supplied gradually into the first process tank and thence further into a subsequent process tank, such that the microbe population initially provided in the process tanks displaces in a step- by-step manner the original microbe population present in the matter to be treated. The matter, which is substantially free of the original microbes and has been expelled from the final process tank, is returned into the first process tank for diluting the matter to be treated. Downstream of the process tanks is conducted a nitrogen removal treatment by feeding the matter to be treated from the process tank (5) of a stripping tower (22A), in which the pH of a matter to be treated has been raised by means of a biological treatment to a level sufficient from the standpoint of nitrogen removal.

摘要： In a single-tank activated sludge process or a multistage activated-sludge process using predation action of animalcules, an improvement in treatment efficiency and a decrease in the amount of excess sludge generation are achieved, while maintaining stable treated water qualities. In a biological treatment wherein organic wastewater is introduced to a first biological treatment tank 1A and is biologically treated with bacteria, the treatment liquid containing the bacteria in the first biological treatment tank 1A is introduced to a second biological treatment tank 1B and is activated-sludge treated, and the treatment liquid from the second biological treatment tank 1B is separated into sludge and treated water, a portion of the sludge in the second biological treatment tank 1B and/or at least a portion of the separated sludge is introduced into a sludge treatment tank 3 having a submerged filter element 4 with a pore diameter of 5 to 100 µm in the tank and is subjected to aerobic biological treatment, and the liquid permeated through the submerged filter element 4 is returned to the first biological treatment tank 1A and/or the second biological treatment tank 1B. Both high effect of reduction in the amount of sludge and satisfactory treated water qualities can be simultaneously achieved by reducing the amount of sludge with animalcules in the sludge treatment tank 3, allowing residual fine components to permeate through the submerged filter element 4, and, again, returning the fine components to the filter predation animalcule tank 1B for predation.

摘要： The invention relates to a filtration device for separating particles from a liquid using hollow-fibre membranes, which are combined to form a fibre bundle. The hollow-fibre membranes are traversed by the liquid from the exterior to the interior and the liquid that has been cleaned of the particles is withdrawn at at least one of the ends of the hollow-fibre membrane. The hollow-fibre membrane bundle is wound onto a support, whose external peripheral surface can be traversed by a gas at least partially from the interior to the exterior. The winding of the hollow-fibre bundle onto the support permits a space-saving arrangement and allows deposited materials to be reliably cleaned from the hollow-fibre membranes. The filtration device can be used on its own or in the form of a module containing several devices for purifying waste water. The invention also relates to a method for purifying waste water using the filtration module and a membrane bioreactor.

摘要： High levels of microbial storage compound (MSC) such as polyhydroxyalkanotaes (PHA) can be produced from wastewater comprising Readily Biodegradable COD (RBCOD) using activated sludge comprising microorganisms capable of accumulating MSC by contacting the wastewater with the activated sludge in the presence of dissolved oxygen during a first period of time, to obtain MSC-loaded activated sludge comprising MSC at a level of at least 60 wt.% based on dry weight of the organic part of the sludge, and then supplying elements essential for growth such as nitrogen and phosphorus and allowing up-take of these elements and limited growth during a second period of time, the supplied amount of at least of one of said essential elements compared to the amount of RBCOD supplied in step a) limiting the growth to an extent that not all MSC is used for growth, to obtain grown activated sludge comprising residual MSC at a level of at least 20 wt.% based on dry weight of the organic part of the sludge; and removing or harvesting part of the MSC-loaded activated sludge and/or part of the grown activated sludge, so that the total average retention time of the sludge is less than 72 h.
