[0002] Giardia and Cryptosporidium, referred to as "the two worms", are widely distributed waterborne chlorine-resistant zoonotic pathogenic microorganisms that can penetrate conventional water treatment processes and enter drinking water systems. Human infection leads to diarrhea, dehydration and even death. There is currently no specific medicine to treat it, and people can only rely on their own immunity. In recent decades, many public health incidents caused by "the two worms" have occurred in developed countries. In order to prevent large-scale infection incidents, it is particularly important to detect the two worm indicators in water. The premise of "the two worms" detection is the enrichment and concentration of water samples.

According to national standards, the amount of water samples required for "the two worms" detection is at least 10L and at most 100L.

The two-worm enrichment device based on the optional dual filtration mode according to claim 8 is characterized in that: A roller (12) and a liquid leakage drain port (13) are provided at the bottom of the box body. If a small amount of water sample leaks into the box body and forms water accumulation during the sampling process, the water is automatically discharged from the liquid leakage drain port (13) at the bottom by changing the angle of the box body.

10. The two-worm enrichment device based on the optional dual filtration mode according to claim 9, characterized in that: The main body of the device is a rectangular parallelepiped made of high-strength lightweight material; the device also includes a buzzer alarm device. When the water sample sampling pressure, water sample sampling volume or water sample sampling flow rate reaches the set value, the equipment stops working and emits a buzzer alarm sound; a waterproof protection device is arranged inside the device to cover the circuit board inside the device and the outside of the electrical components; the top of the device is equipped with a metal filter to intercept large particles of impurities in the water sample.
