Abstract

The invention relates to an activated sludge settling concentration comprehensive performance measuring device and measuring method, and is characterized in that the measuring device comprises a settling column; the settling column comprises an upper-layer chamber and a lower-layer chamber; a drain pipe is arranged on the bottom of the upper-layer chamber; a water suction pump is arranged in the lower-layer chamber; an inlet of the water suction pump is connected with a sampling pipe penetrating through the side wall of the lower-layer chamber; an outlet of the water suction pump is connected with a pipeline extending into the upper-layer chamber; an aerator is arranged in the lower-layer chamber and is connected with an aeration head through a gas pipe extending into the upper-layer chamber; an ultrasonic signal transmitting sensor and an ultrasonic signal receiving sensor are arranged on the top of the upper-layer chamber; an infrared light emission sensor and an infrared light detector are arranged at the middle part of the upper-layer chamber.

Description

technical field [0001] The invention relates to an activated sludge settling concentration comprehensive performance measuring device and a measuring method applied in a sewage treatment system, belonging to the field of sewage treatment. Background technique [0002] The activated sludge method is the most traditional and important method in the biological treatment of urban sewage. The production environment conditions of the sewage treatment process are changeable and harsh (such as changes in influent water quality, climate changes, changes in microbial populations, etc.), and its treatment effect Susceptible to the interference and influence of the external environment, resulting in sewage treatment can not be carried out normally. For example, the sedimentation and concentration performance of activated sludge will be affected by the change of sewage composition in the rainy season, which is mainly caused by the change of ionic strength in the sludge. Once the sediment...
