Device and method for realizing partial short-range nitrification-anaerobic ammonia oxidation by adding hydroxylamine

The invention discloses a device and a method for realizing partial short-range nitrification-anaerobic ammonia oxidation by adding hydroxylamine, and belongs to the field of urban domestic sewage biological treatment. For two-stage partial short-range nitrification-anaerobic ammonia oxidation, the stable operation of the short-range nitrification is crucial to a process; the short-range nitrification is very difficult to start and maintain stably only through process parameter control; a very good nitrite accumulating effect can be achieved by adding the hydroxylamine in the patent; partial short-range nitrification reactors can be started and high nitrite accumulation can be maintained within a short time. The hydroxylamine serves as an intermediate product in a nitrifying process, is a reducing agent of ammonia monooxygenase and a stimulating agent of AOB (Ammonia Oxidizing Bacteria) and can improve the cell yield of the AOB; meanwhile, the hydroxylamine is an inhibiting agent of NOB (Nitrite Oxidizing Bacteria) and can elutriate the NOB. Compared with a conventional denitrogenation process, a partial short-range nitrification-anaerobic ammonia oxidation process can save aeration quantity and carbon source, and is particularly suitable for urban domestic sewage with low C/N.

Surgical cutting device

The present invention provides a single-use surgical cutting device for cutting a planar piece of tissue into a predetermined shape. The cutting device comprises a housing having one or more side walls, a top, a base, and a hollow interior portion. A blade retaining member is disposed within the housing between and substantially parallel to the top and base such that the blade retaining member can move vertically between the top and base. A blade defining a predetermined tissue shape is disposed on the bottom surface of the blade retaining member. A pressure mechanism creates potential energy for exerting a downward force on the top surface of the blade retaining member, such that when the blade retaining member is released, the pressure mechanism forces the blade retaining member downward with sufficient force to cut the piece of tissue. An actuator is configured to release the blade retaining member only once without disassembling the housing and resetting the pressure mechanism. Thus, a piece of tissue can be placed beneath the bottom surface of the blade retaining member on or parallel to the base and the actuating mechanism can be actuated to release the downward force on the blade retaining member to cut the piece of tissue into the desired shape, but the cutting device cannot readily be reused by an operator.
