Embodiment 1

[0033] For the actual sewage treatment plant using the activated sludge method, the user only needs to hold the sampling rod 2, refer to the scale on the rod body, place the multifunctional conical drill bit 1 at the specified height point under the liquid level of the process unit, and then pull up The handle 11 opens the rectangular baffle switch 9, and the water sample at this height in the reactor flows into the sampling rod 2 under pressure, and enters the silica gel tube 3 after being filtered by the orifice filter screen 12 in the rod, and then turns on the peristaltic pump 4, and the The water sample is pumped into the water collecting device 5, and then various indicators thereof are conveniently measured using an online instrument. Finally press the handle 11 to close the rectangular baffle 9.

[0034]When it is necessary to take out the activated sludge in the pool, you only need to put the multi-functional drill bit 1 on the designated mud-taking place, then pull u...

Embodiment approach 2

[0036] For the biological filter process of the reclaimed water plant, since the reaction unit is filled with filter material, it is necessary to drill the multifunctional drill bit 1 into the specified height under the filter material layer, and then pull the handle 11 to open the rectangular baffle switch 9, and the reaction unit The water sample at this depth point flows into the sampling rod 2. At this time, the orifice filter screen 12 in the tube plays a role in intercepting and blocking the filter material in the filter tank. The filtered water sample enters the silicone tube 3, and then the peristaltic filter is opened. The pump 4 pumps the water sample into the water collecting device 5, and then uses the online instrument to measure its various indicators conveniently, and finally presses the handle 11 to close the rectangular baffle switch 9.

[0037] When it is necessary to take the filter material in the filter tank, drill the multi-functional drill bit 1 into the ...

Embodiment approach 3

[0039] For the biofilter under small-scale conditions in the laboratory, it is only necessary to disconnect the silicone tube 3 from the top of the sampling rod 2 and connect it to the corresponding sampling point of the reactor. Then the peristaltic pump 4 is turned on, and the water samples are directly collected in the water collection device 5, and then various indicators are measured.

Abstract

The invention provides a sewage plant and recycled water plant in-situ sampling and on-line test device and an operation method of the sewage plant and recycled water plant in-situ sampling and on-line test device, and belongs to the technical field of in-situ sampling and test devices. The bottom surface of a conical drill is fixedly connected with a cylindrical sampling rod in a sealing mode, a sampling opening is formed in the lateral side of the bottom end of the sampling rod, a baffle serves as a switch of the sampling opening, and the top of the baffle is connected with a metal rod connected with a handle; a hole plate filter screen is arranged above the sampling opening and is communicated with a silicone tube, and the silicone tube is connected with a water collecting device through a peristaltic pump; the water collecting device is provided with a probe in a sealed mode, and the probe is connected with an instrument. The drill is extended to an appointed depth under a liquid surface, and then the handle is pulled upwards to make the baffle and the sampling opening staggered, a water sample in an in-situ point to be tested flows into the sampling rod under the action of pressure, is filtered through the hole plate filter screen in the rod and then enters the silicone tube, and then the peristaltic pump is opened, and all kinds of indexes of the water sample entering the water collecting device are measured through the probe in real time. The method is flexible, simple, accurate, safe and reliable.

Description

technical field [0001] The invention relates to a method capable of in-situ sampling at any sampling point of a sewage plant and a reclaimed water plant, and online testing of DO, pH, ORP, and NH 4 + , NO 3 - The device with equal parameters and its operating method belong to the technical field of in-situ sampling and testing devices. Background technique [0002] With the increasing amount of urban sewage treatment in the country and the reclaimed water of sewage in large and medium-sized water-deficient cities, the water pollution problem in my country has been alleviated to a certain extent, but the overall operation level of sewage treatment plants and reclaimed water plants is still low. At the same time, new sewage treatment processes And reclaimed water treatment process, although there are many small-scale and pilot-scale research results, but the actual engineering application of the process still needs to be further solved. Therefore, in-depth research on actua...
