Embodiment

[0057] Such as figure 1 As shown, the online water quality monitoring system of the sewage plant provided in this embodiment is an integrated cabinet structure, including a sewage supply system, a reactor, a backwashing system, a dosing system, and an electrical system. The sewage supply system enters the reactor 1 through the water inlet pump 3, the manual regulating valve 4, the water inlet valve 5, the self-cleaning filter 6, and the flow valve 7; the right side of the reactor is a mixing system of biological carrier and sewage, Sewage enters from the bottom, overflows from the upper end to the left side, aerates the reactor through the second air pump 8 and the gas flow controller 9, and uses the DO sensor 2 to monitor the dissolved oxygen in the reactor; the DO sensor and the electrical system 14 are connected to collect and process the monitored data, and obtain OUR data; the biofilm falling off in the reactor and the venting of the reactor are realized through the drain...

Abstract

The invention discloses an online water quality toxicity monitoring system for a sewage plant. The online water quality toxicity monitoring system comprises a reactor, an aeration device, a sewage supply device, a dosing device, a collection and treatment control device and a backwashing device, wherein the interior of the reactor is vertically divided into a right side reaction space and a left side monitoring space, the right side reaction space is communicated with the left side monitoring space through the upper part, and a biological carrier and an aeration device are arranged in the right side reaction space; a water inlet pipe is arranged at the bottom of the reactor and communicated with the right side reaction space; the reactor side wall of the left side monitoring space is connected with a water outlet pipe; the sewage supply device is connected with the water inlet pipe of the reactor; the dosing device is connected with the water inlet pipe of the reactor; the collection and treatment control device is electrically connected with a DO sensor arranged in the left side monitoring space of the reactor, and monitoring data can be collected and treated through the DO sensorto obtain OUR data; and the backwashing device is connected with the sewage supply device. The system is simple in structure, sludge is not needed, and monitoring data is real and accurate.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an online water quality toxicity monitoring system for a sewage plant. Background technique [0002] Sewage treatment plants are more vulnerable to the onslaught of toxic wastewater because they collect and treat a wide variety of wastewater. There are many kinds of toxic and harmful pollutants in industrial wastewater, with high content and great harm. When the toxic wastewater enters the sewage treatment plant using the activated sludge method, it will inhibit and poison the microorganisms in the activated sludge, which may lead to an unfavorable transformation of the microbial community, inhibit the biological activity of the activated sludge, and reduce the microbial The treatment efficiency of the sewage treatment plant will be destroyed, and the normal operation of the sewage treatment plant will be destroyed, and the effluent water quality of the sewage treatment plant wil...
