The invention discloses a high-efficiency drying device for preparing Chinese herbal decoction pieces. The two ends of the oven are respectively provided with an intake air distribution chamber and an air outlet concentrating chamber, and an air inlet pipe communicating with the air intake distribution chamber is fixedly connected to one end of the oven close to the air intake distribution chamber. The invention adopts the energized thin resistance wire as the drying component, and takes advantage of its characteristic of heating and glowing red after energization, and mainly uses heat radiation to heat and dry the Chinese herbal medicine pieces. Compared with the traditional hot air drying and high temperature environmental drying methods In other words, the heat utilization rate is higher, the energy saving is more, and the drying efficiency has been significantly improved. During the drying process, because the drying chamber is in a negative pressure state, the water is easier to evaporate, so that the drying of the Chinese herbal medicine pieces can be efficiently completed. Work, not only the drying speed is fast, but also the drying effect is good.

The invention provides a method for adjusting biological denitrification and dephosphorization by using a concentration gradient, comprising the steps of: (1) detecting the concentration of parameters at different positions along the water flow direction in anaerobic ponds, anoxic ponds and aerobic ponds; (2) ) Compare the detected concentration with the corresponding theoretical concentration gradient trend, and adjust the parameters that do not meet the corresponding theoretical concentration gradient trend; (3) After the adjustment is completed, adjust the key parameters that do not meet the corresponding theoretical concentration gradient trend.
