Abstract

The invention discloses a control method and detection device of sewage aerobic treatment dissolved oxygen. The control method includes: using a dissolved oxygen tester to cooperate with the detectiondevice to detect dissolved oxygen content in an aerobic tank; transmitting the dissolved oxygen content obtained by detection to a computer data processing system; comparing the dissolved oxygen content with set upper-lower limit data of dissolved oxygen content by the computer data processing system. Processing is realized through a computer software data system, the on-site dissolved oxygen tester is mounted in the aerobic tank, data are connected into the computer data processing system which sets a dissolved oxygen range, an air compressor is automatically started to aerate the aerobic tank when dissolved oxygen content reaches a lower limit, and the air compressor is stopped from running when the dissolved oxygen content reaches an upper limit, so that automatic aerobic aeration is realized, running stability of a sewage treatment aerobic system is ensured, and energy is saved. A sampling pipe is arranged in the aerobic tank, direct sampling analysis of sewage at different depthand height can be realized, manual collection is not needed, and continuous sampling analysis can be realized, so that time and manpower are saved.

Description

technical field [0001] The invention relates to a method for controlling dissolved oxygen, in particular to a method for controlling dissolved oxygen in sewage aerobic treatment and a detection device thereof. Background technique [0002] Oxygen dissolved in water is called dissolved oxygen DissolvedOxygen, abbreviated as DO, and dissolved oxygen exists in water in a molecular state. The amount of dissolved oxygen in water is one of the important indicators to measure water quality and aerobic treatment. [0003] There are two factors that affect the dissolved oxygen content in the aerobic stage of sewage treatment: one is the oxygen consumption that reduces DO, including the oxygen consumption in the degradation process of aerobic organic matter and the oxygen consumption of biological growth; the other is the increase in DO Oxygenation mainly uses an air compressor for aeration to increase oxygen supply and dissolution. The combined effect of these two effects makes the...
