Description

Technical Field

[0001] The invention relates to the technical field of sewage monitoring, in particular to a water quality monitoring device for a sewage pipe network of a sewage pump station. Background Art

[0002] With the progress of society and the development of industry, people's lives have been changed for the better. However, the industrial water pollution that has emerged in recent years has become more and more serious. Water pollution is the reduction or loss of the use value of water caused by harmful chemicals. Acids, alkalis, oxidants, heavy metals and compounds in sewage will poison aquatic organisms and affect drinking water sources and scenic landscapes. When organic matter in sewage is decomposed by microorganisms, it consumes oxygen in the water and affects the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobically decomposition to produce unpleasant gases such as hydrogen sulfide and mercaptans, which further deteriorate the water quality. At present, the water discharged by many factories does not meet the discharge requirements, so timely water quality monitoring is required.

[0003] Existing sewage monitoring devices need to collect sewage samples from the sewage network for testing at regular intervals in order to achieve the purpose of real-time monitoring of the quality of discharged sewage. Since the existing monitoring devices collect sewage samples randomly in the sewage network, more solid impurities will be mixed in the sewage. During the detection process, the collected sewage samples need to be left to stand for a long time in order to separate the supernatant and solid impurities at the bottom of the sewage samples. However, this long standing time will affect the detection efficiency, and the inability to collect sewage samples in a targeted manner will also make the detection results single, which is not conducive to achieving the purpose of accurately monitoring sewage quality.

When collecting the sewage in the flow chamber 2 6, the guide plate 105 can be tilted to transport the sewage to the storage chamber 2 104. If the turbidity of the sewage in the flow chamber 1 5 is high, the inclined filter screen plate 106 is used to filter the sewage for a second time when transporting the sewage to the storage chamber 2 104. When diverting the sewage to the storage chamber 1 103 again, the impurities on the filter screen plate 106 will naturally fall into the storage chamber 1 103.

[0043] Working principle: When sewage is normally transported, the arc baffle 1 31 and the arc baffle 2 41 are respectively located in the upper and lower directions, completely covering the cross-section of the connecting pipe 1. At this time, the arc baffle 1 31 and the arc baffle 2 41 achieve a filtering effect. When it is necessary to collect sewage samples, the sampling tube 91 can be controlled to move to the flow chamber 1 5 or the flow chamber 2 6. According to the effect of gravity, the turbidity of the liquid in the flow chamber 1 5 is relatively high at this time, and the main substance is solid impurities, while the turbidity of the liquid in the flow chamber 2 6 is relatively low. The two chambers can be sampled separately to obtain liquids with different turbidities, so that the subsequent detection efficiency is improved. At this time, only the arc baffle 1 31 is controlled to completely fit with the arc baffle 2 41 when moving, so that the flow chamber can be made into a closed space. At this time, the liquid inside it is sampled, and static sampling, that is, directional sampling, can be achieved to avoid being affected by the sewage flow, resulting in flow before the sample is completely taken. According to the above method, the flow chamber 1 5 can be adjusted to a closed space for sewage sampling to achieve the purpose of stratified sampling.
