Embodiment 1

[0084] The embodiment of the present invention provides an online warning device for water quality toxicity based on the monitoring of microbial respiration and oxygen consumption. The microorganisms in the water sample to be monitored are used as the microorganisms. The device can work in the following steps:

[0085] Step 1: Microbial cultivation. After power on, the controller controls the pump valves on each pipeline, so that the tested water sample flows into the bioreactor after simple filtration, and saturated dissolved oxygen water is added to the bioreactor, and nutrients are also added according to the actual situation, so that The microorganisms in the tested water sample are quickly cultivated in the bioreactor according to their natural composition ratio, so that the ecological state of the tested water sample is relatively realistically simulated.

[0086] Step two: dynamic balance. Since the value of dissolved oxygen in saturated dissolved oxygen water is const...

Embodiment 2

[0091] The embodiment of the present invention provides an example of using an online water quality toxicity early warning device based on microbial respiration and oxygen consumption monitoring to perform online early warning of water toxicity monitoring in a reservoir. The microorganisms are single microorganisms artificially cultivated in the laboratory. The specific process is as follows:

[0092] In a large reservoir as a drinking water source, the water quality of the reservoir is strictly monitored, and the online warning device for water quality toxicity is used as an auxiliary facility for manual detection.

[0093] Microorganisms grow in the plastic ring attached to the bioreactor under laboratory conditions. When the online warning device is turned on, a stable baseline can be obtained after one hour, and the warning device starts to work.

[0094] Monitor the dissolved oxygen level remaining in the bioreactor, and make a curve of microbial respiration oxygen consump...

Abstract

The invention discloses a microbe breathing oxygen consumption monitoring-based water toxicity on-line early-warning device and method and relates to the technical field of water toxicity on-line early warning. According to the method, microbes are cultured in a bioreactor, through control of conditions, microbe growth is in a dynamic balance state so that a dissolved oxygen value in the bioreactor is in a stable state, when water contains toxic pollutants, microbe respiration intensity is changed so that a dissolved oxygen level in the bioreactor is changed, and through acquisition of change of the dissolved oxygen level, water toxicity pollution on-line early warning is realized. The device realizes on-line monitoring of a dissolved oxygen level in the bioreactor only by a dissolved oxygen sensor, is used simply, has good maneuverability, does not need special reagent or apparatus, is maintained simply and has a low operation cost.

Description

technical field [0001] The invention relates to the technical field of online water quality toxicity early warning, in particular to an online water quality toxicity early warning device and method based on microbial respiratory oxygen consumption monitoring. Background technique [0002] With the rapid development of our country's industrial level and the rapid improvement of people's living standards, environmental pollution has become one of the major problems our country is currently facing. According to the statistics of the environmental protection department, the nine major water systems in the country have been polluted to varying degrees, most of which are quite serious, directly threatening the ecological environment of the water body and the normal life of the people. Fresh water resources, which were not rich in the first place, have become even more scarce. Therefore, paying attention to water quality safety and drinking water safety is a major issue related to...
