There is provided a water quality probe system, the system comprising: one or more water contact sensors; a geolocation unit; a processing circuitry (PC), operably connected to the one or more water contact sensors and to the geolocation unit, the PC being configurable to: receive, from one or more of the water contact sensors, data indicative of one or more water characteristics sensed from contacted water; receive, from the geolocation unit, data indicative of a current geographical location; and determine data indicative of whether the contacted water satisfies one or more water quality criteria, utilizing, at least, the received sensed water characteristics and the current geographical location.

This invention relates to the field of environmental microbiology technology, and discloses a rapid aerobic degradation compound microbial agent for use in ecological public toilets under overload conditions, its preparation method, and its application. The compound microbial agent is composed of component A and component B at a live bacteria ratio of 1:1-3. Component A includes a lipolytic strain of *Pichia pastoris* FJQC-XJ-4 (CICC33293) acclimated under high organic load gradient conditions; component B includes a bacteriocin-producing strain of *Lactobacillus plantarum* bio-61663 (CICC24435). Under simulated overload conditions, the compound microbial agent achieves an organic matter degradation rate of 71.8% and a fecal coliform kill rate of 99.8%. The agent exhibits a high survival rate after 180 days of storage at room temperature and is suitable for emergency treatment of excessive sewage loads in scenic areas, highway service areas, and other locations during holidays.

The utility model relates to the technical field of detection equipment, and discloses a fecal coliform group detection device based on a fluorescence induced spectrum analysis technology, which comprises a machine body, a sliding table is arranged on the upper surface of the machine body in a sliding manner, a rotating column is fixedly arranged on the upper surface of the sliding table, and a rotating table is arranged on the outer wall of the top end of the rotating column in a penetrating and rotating manner; and a conversion assembly is arranged in the machine body. Through arrangement of the conversion assembly and cooperation with rotation of the rotary table, the mounting cylinder can rotate on the rotary table under the action of the half gear ring, when the half gear ring is disengaged from contact with the gear ring, due to the elastic force of the coil spring, the mounting cylinder can rotate reversely, and the mounting cylinder can move in the arc-shaped groove through the arc-shaped sliding block; the half gear rings rotating in the reverse direction do not generate large impact force on the gear ring, so that a culture medium in the mounting cylinder can repeatedly shake, flora in a water sample is promoted to be dyed, and the inspection efficiency of the equipment is improved.
