Description of the invention (!) The invention is related to Biological wastewater treatment method The mixture of sludge and wastewater is treated with gas in the activation stage and the activated sludge is separated from the treated wastewater flotation. This type of method has been disclosed, for example, in German Patent Application No. P 44 1 1 99 1. 7 It is also used as a reference in this article. • In the method printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page), the sludge system and hydraulic load should be The wastewater leaves the activation stage together, and is separated from the hydraulic load by flotation in the separation stage, and a part of it is recycled back to the activation stage to maintain the determined sludge wave length during the activation stage * because of the direction of this operation Therefore, there is a correlation between the concentration of the sludge in the activation phase and the withdrawal from the separation phase to the activation phase—the so-called reflux sludge discharge stream—1 degree. The sludge concentration in the activation stage is therefore determined by the mixture of the returning sludge and the almost solid-free wastewater. The sludge concentration in the activation phase set by this method is usually 5 g / liter (see the above patent application). The sludge concentration is an important parameter in the size design of the wastewater biological treatment plant. Not to mention, the capacity of the activation reactor can be determined, and the volume will decrease as the concentration of the sludge increases. Therefore, a wastewater treatment plant that can be operated at a considerable concentration of sludge will have no serious disadvantages. requester. The lack of viscosity of their workers lies in the flotation separation part of the process. Depending on the concentration of the sludge, it must be made very large, and accordingly becomes very expensive. Changes in the flow rate have a very sensitive response and are difficult. In addition, the high wastewater flow rate required for flotation has a direct proportional relationship with the concentration of sludge, which makes its operating cost very high. This paper scale applies Chinese national standards ( CNS) A4 specification (210X297 gong)] A7 _B7 V. Description of the invention (2) It is surprisingly found that if the method of the type mentioned at the beginning is modified to an activated sludge concentration of 26 g / l in the activation stage and When the flotation system is a type of dissolution method described below, these disadvantages are significantly reduced. In summary, the present invention relates to a biological wastewater treatment method in which a mixture of activated sludge and wastewater is treated with a gas in the activation stage And floated off in the buried water of live loach, where the activated sludge concentration in the activation stage was 26 g / L and where the flotation was dissolved air flotation • a preferred implementation of the method of the present invention It is given by items 2 to 3 of the scope of patent application. The first preferred embodiment of the method of the present invention is that the activated sludge concentration in the activation stage is 28 g / l, preferably 210 g / l, particularly The better is 2 1 2 / liter. Another preferred embodiment is that the suspension used for flotation is guided at a flow rate of S 0.3 m / s toward the central standard of the Ministry of Natural Economy. Printed by the local shellfish consumer cooperative (please read the precautions on the back before filling this page). In this case, the gas treatment device is used to treat the suspension with gas. The gas treated suspension is in the gas treatment device. The bottom is removed and given to the flotation operation * as described in German patent application P 44 11 991.7. Individual features or features among the features mentioned in the embodiments can also individually constitute the solution of the present invention, and individual special dependencies can also be combined. The advantages of the method of the present invention are basically The wastewater biological treatment plant's activation stage and flotation stage can be made smaller than traditional wastewater treatment plants. In this way, it can improve its efficiency and simplify its operation. This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) 5 A7 _ ^ _ B7___ V. Description of the invention (3) One possible embodiment of the method of the present invention is to refer to the program flow chart shown in the appendix below Explain in more detail. Wastewater_1 is mixed with aerated sludge called reflux sludge 7 in the activation chamber 2 of the activation stage and aerated 3. In the process, the pollutants contained in the wastewater are biodegraded. The mixture of sludge and water is then passed to a vertical upright reactor 4. The downflow reactor 4 which is used as a gas treatment device is used to guide the mixture of activated sludge and water downward and in the process. Ventilation • If necessary, a flocculant 1 2 can be added. Then the active sludge and water mixture is taken out from the bottom of the downflow reactor 4 and fed into the flotation cell 5 where the active sludge is separated from the water. Out • This separation can be enhanced by the method of releasing water and air 10 from the pressurized water station 6 into high pressure and releasing it into the flotation cell 5. • The water used for this method is purified wastewater 1 1 * Use Tower 1 3 serves as a storage tank. • A part of the separated activated sludge is recycled to the activation chamber 2 as reflux sludge. 7 The rest is discarded as excessive sludge. • The purified wastewater is passed through The outlet 9 is taken out in the form of clarified water. The present invention will be further explained by two operating examples. Printed by the Shellfish Consumer Cooperative of the Central Bureau of Quasi-Ministry of Economic Affairs (please read the precautions on the back before filling out this page). Wait The example is related to a biological wastewater treatment plant, in which the activated sludge is separated by dissolved air flotation using an upstream downflow tower as described above. At the upstream of the biological treatment, the primary clarification of the wastewater is performed. The activated sludge concentration increases. In each case, the biomass formed by these special wastewaters did not show any obvious change in the decomposition kinetics. Consider the restriction of the increase of the solid content concentration for the individual metabolic process of the individual components contained in the wastewater. • In the individual examples, the volume of the mutation activation chamber and the paper rule are in accordance with the Chinese National Standard (CNS).
