Description
Technical Field
The invention relates to the field of inspection well water quality monitoring, in particular to an inspection well early warning management system for monitoring water quality.
Background
Inspection wells, which are ground access openings for underground pipelines, are typically covered by inspection well lids. In cities, all public water supplies, sewer pipes, telephone lines and optical fiber networks may be connected through underground passages under inspection wells. The inspection well of the sewage channel is an important channel leading to the sewage channel, and when a sewage sample in the sewage channel is collected, the sewage sample is often collected from the inspection well.
Regarding sewage canals, the zero-line sewage discharge project of municipal works is actively spreading everywhere. The zero-direct sewage drainage project is characterized in that sewage generated in production, life and operation activities is collected in a sewage interception and collection mode, and the sewage can be discharged to an external environment after being treated to reach standards, so that 'no water is drained in sunny days, and no sewage is drained in rainy days'. Sewage generated by production, life and operation activities is collected in a sewage interception and receiving pipe and unified manner, and is discharged to an external environment after being treated to reach the standard, so that urban sewage collection and rainwater and sewage distribution are realized.
The project of zero-straight sewage drainage has many problems in engineering practice, such as direct discharge into the sewage channel without interception or treatment, or poor effect of the sewage interception receiving pipe, which causes untreated sewage to directly escape into the sewage channel. The untreated sewage is directly discharged into the sewage canal, and for this reason, the sewage discharge point is usually inspected by manpower in a chemical inspection mode, and whether the sewage is directly discharged or not is determined according to the analysis of the inspected sewage components, and then the tracing is performed. However, the manual spot inspection method is lack of real-time performance and complex in underground pipe network, and after directly-discharged sewage is spot inspected, the sewage possibly spreads over the underground sewer, so that the source tracing point is difficult to confirm. Secondly, the sewage is directly discharged only because of leakage for a while, and the leakage is stopped during tracing, thereby increasing the difficulty of tracing. And thirdly, due to the complexity of sewage components, different organic matters in different sewage components can float or settle, the sewage in the upper layer, the middle layer and the lower layer at the same point is taken, the detection results are possibly inconsistent, comparative analysis is needed, and the workload and the working difficulty are increased. If a sensor is used to detect sewage, since the height of the sewer level is dynamically changed, if the sensor is exposed to the water surface, an erroneous detection result may be transmitted.
