Embodiment

[0033] Please refer to figure 1 , this embodiment provides a sewage collection device 100 for virus and bacteria monitoring, which includes a filter unit 110 , a power unit 120 and an enrichment unit 130 linked in sequence.

[0034] Please refer to figure 1 with figure 2 , the filter unit 110 includes a fixed plate 111 with a through hole 114 opened, a water-permeable stainless steel shell 112 and a 5-stage filter layer 113 . The water-permeable stainless steel casing 112 forms a funnel and the free end is fixed to the fixed plate 111. The 5-stage filter layer 113 is sleeved in the funnel surrounded by the above-mentioned water-permeable stainless steel casing 112. The pore size of the 5-stage filter layer 113 gradually decreases from the stage near the water-permeable stainless steel shell 112 . In this embodiment, the pore sizes of the above-mentioned five-stage filter layer 113 are respectively 5-10 microns, 10-20 microns, 20-50 microns, 50-100 microns and 100-300 micro...

Abstract

The invention discloses a sewage collection device for monitoring viruses and bacteria, and relates to the technical field of sewage collection. The sewage collection device for monitoring viruses andbacteria comprises a filter unit, a power unit and an enrichment unit which are connected in sequence. The filtering unit comprises a fixed plate with a through hole, a permeable stainless steel shell which is encircled into a funnel shape and of which a free end is fixed to the fixed plate, and a five-stage filtering layer which is arranged in a funnel encircled by the permeable stainless steelshell in a sleeving manner; the power unit comprises a sleeve penetrating through the fixed plate through the through hole, a second-stage composite nested piston pump with a piston movably arranged in the sleeve, and a power source connected to the second-stage composite nested piston pump; and the enrichment unit comprises a plurality of enrichment bottles arranged in series, enrichment films arranged in the enrichment bottles and a plurality of automatic switching valves arranged on the pipeline and used for controlling the enrichment bottles. The sewage collection device for monitoring viruses and bacteria adopts a continuous sampling mode to realize uninterrupted monitoring of viruses and bacteria in sewage.

Description

technical field [0001] The invention relates to the technical field of sewage collection, in particular to a sewage collection device for monitoring viruses and bacteria. Background technique [0002] The new coronavirus can show up in urine and feces. In cities, these viruses in urine and feces are often discharged into the sewage system. In addition, people's washing process will directly release the virus into domestic sewage. These suggest that an important destination of the virus in the city is to enter the sewage system, which provides the possibility to monitor the epidemic through sewage. Analyzing domestic sewage, isolating viruses in sewage, and monitoring them with modern biological techniques such as next-generation sequencing will be able to overcome the shortcomings of traditional epidemiology mentioned above. [0003] For the monitoring of viruses and bacteria in sewage, effective sewage sample collection is required. The existing sewage collection meth...
