Abstract

The invention relates to the field of public drinking water hygienic security detection and provides a filtering recovery device related to cryptosporidium and giardia for solving the problem that theexisting device for detecting the cryptosporidium and giardia is complicated in detection programs and high in detection cost and a system thereof. The recovery device comprises a left filtering assembly, a right filtering assembly and a filter element, wherein the left filtering assembly comprises a water sample barrel, a water sample peristaltic pump, a left filter cup and a washing liquor collection barrel; a water sample inlet hole and a left filter cup exhaust hole are formed in the top of the left filter cup, and a washing liquor drain hole is formed at the bottom of the left filter cup; the right filtering assembly comprises a washing liquor barrel, a washing liquor peristaltic pump, a right filter cup and a water sample collection barrel; a washing liquor inlet hole and a right filter cup exhaust hole are formed in the top of the right filter cup, and a water sample collection hole is formed in the bottom of the right filter cup; solenoid valves are arranged at the previous holes; the filter element is fixedly arranged between the left filter cup and the right filter cup; the pore size of filter paper at the filter element is less than overall dimensions of the cryptosporidium and giardia.

Description

technical field [0001] The invention relates to the technical field of sanitation and safety detection of public drinking water, in particular to a filtration and recovery device for cryptosporidium and giardia. Background technique [0002] Cryptosporidium and Giardia (referred to as "two insects") are two pathogenic protozoa that seriously endanger water quality safety. Cryptosporidium and Giardia in urban water supply systems directly threaten the safety of drinking water, and at the same time bring ecological and health risks to the urban water environment. The pathogenic dose of Giardia is 10-100 live cysts, and the pathogenic dose of Cryptosporidium is only 1-10 live oocysts. There are no special clinical symptoms, no preventive vaccines, and most antibiotics are ineffective after Cryptosporidium or Giardia infection, and the treatment depends on the body's own resistance. [0003] At present, the spores or oocysts of Cryptosporidium and Giardia have become the large...
