The invention discloses a processing method of nostoc commune. The processing method comprises the following steps of (1) adding water to a vortex air pump cleaning pond for soaking; (2) opening a vortex air pump for flushing, and after performing drainage, performing flushing for the second time with the vortex air pump; (3) under the condition of minus 10 to 0 DEG C, performing freezing in a refrigerating chamber, loading frozen nostoc commune in a kraft paper box, performing sealing, performing burying in loess to which diatomite is mixed, and performing purifying; (4) performing drying ina vacuum box until the water content is 18-25%; (5) loading an appropriate amount of white fused alumina powder to the kraft paper box, and burying the nostoc commune in the white fused alumina powder; (6) putting the kraft paper box in a fresh keeping cabinet with a drying agent, enabling the fresh keeping cabinet to be placed under the condition of constant temperature for 48-60 hours, and gently brushing away powder stuck to the surface of nostoc commune with a brush; and (7) performing blasting in an air box, performing drying for 12 hours, taking out the dried nostoc commune, performing cutting, and performing sorting and classifying with a sieve so as to obtain the natural nostoc commune. The condition that nutrient components of the nostoc commune do not run off is guaranteed to themaximum extent, original appearance, shape and color are maintained, and the product quality is improved.

The invention discloses an A / O reactor capable of achieving reflux without a pump. The A / O reactor comprises an anoxic tank, an aerobic tank, and a precipitation tank. A micropore aerator is arranged on the bottom of the aerobic tank; the bottoms of the anoxic tank and the aerobic tank are communicated with each other; the bottoms of the aerobic tank and the precipitation tank are communicated with each other; the precipitation tank can be divided into a precipitation buffer area and a precipitation area, the bottoms of the precipitation buffer area and the precipitation area are communicated with each other; an inclined cover plate is arranged on the aerobic tank, the end part of the higher end of the cover plate stretches out the anoxic tank and is provided with an overflow weir slot, and a water discharge weir plate is arranged in the middle of the cover plate. The provide self-circle A / O reactor utilizes the air lifting effect during the aeration process in the aerobic tank to bring the mixed liquid in the aerobic tank back to the anoxic tank so as to achieve the circulation of mixed liquid without a pump. At the same time, the bottoms of the precipitation tank and the aerobic tank are communicated, so that the sludge in the sludge hopper will be sucked into the aerobic tank when the mixed liquid in the aerobic tank is lifted up by the gas during the aeration process, thus the sludge reflux can be achieved without a pump, the energy is saved, and the nitrogen removal efficiency is improved.
