[0019] Figure 1 This is a schematic structural diagram of Example 1;

[0020] Figure 2 This is a schematic diagram of the structure in Example 2.

[0021] The figure shows: sampling box 1, water pump 2, control valve 3, and measuring instrument 4. DETAILED DESCRIPTION

[0022] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art further understand the present invention, but are not intended to limit the present invention in any way. It should be noted that a person skilled in the art may make various variations and improvements without departing from the scope of the present invention. Such variations and improvements are all within the scope of protection of the present invention.

[0023] Example 1

[0024] The present invention provides a continuous measurement device for sewage treatment, comprising a sampling box 1, a water pump 2, a control valve 3, and a measuring instrument 4. The measuring instrument 4 is located within the sampling box 1, connected to the water pump 2. The water pumps 2 are connected to target detection locations via pipes, each equipped with a corresponding control valve 3. The measuring instrument 4 includes a measuring instrument body and an instrument reader. The measuring instrument body is connected to the instrument reader via a circuit. The measuring instrument body is connected to the interior of the sampling box, while the instrument reader is located outside the sampling box.

[0025] Working Principle: Water samples are drawn by pump 2 and temporarily stored in sampling box 1. Water quality data is measured by measuring instrument 4. After measurement, the water in sampling box 1 is promptly discharged, and measuring instrument 4 stores and transfers the data. Valve 3 is controlled to open and close channels for sampling at different monitoring locations at different times. This process can be run continuously, measuring water quality data from samples taken at different locations and at different times along the wastewater treatment process.

[0026] More specifically, the volume of the sampling box 1 can be set to 10-30L to meet the measurement requirements of the measuring instrument 4 while ensuring that the water quality in the sampling box 1 is relatively uniform and does not have large deviations. The sampling box 1 is equipped with a stirring device to ensure uniform water quality in the sampling box 1. The residence time of the water sample in the sampling box 1 does not exceed 30 minutes, which reduces or prevents the biochemical reaction process that may occur in the sampling box 1 from affecting the final water quality measurement results.

[0027] The flow rate of water pump 2 can meet the requirement that the residence time in sampling box 1 does not exceed 30 minutes, and can be adjusted; the flow rate of water pump 2 needs to take into account that the channel may be long, and the required negative pressure and positive pressure should meet the requirements of hydraulic circulation. Water pump 2 can be of gravity, self-priming and other types, and can realize timed start and timed shutdown functions. There can be multiple control valves 3, each valve controls one channel, which can connect the water sample at the target monitoring position to water pump 2, and send the water sample to the sampling box through the operation of water pump 2. Each of the control valves 3 can realize timed start and timed shutdown functions to ensure that the entire channel is a single channel and the singleness of sampling is guaranteed.

[0028] Measuring instrument 4 can measure water quality indicators that include or partially include elements such as C, N, and P, and can be selected based on monitoring requirements. Measuring instrument 4 can store and transfer data, and can send data to the water plant's central control room via the cloud, enhancing the timeliness of monitoring. Measuring instrument 4 should be cleaned, parts replaced, and returned to the factory for maintenance in a timely manner according to the requirements of the measuring instrument to ensure measurement stability and accuracy. Measuring instrument 4 should comprehensively consider the convenience, timeliness, stability, and accuracy of monitoring. Measuring instrument types using optical or chemical methods can be selected; it is recommended to select an optical instrument that meets stability requirements to achieve higher convenience and timeliness requirements.

Traditional methods require the purchase of seven COD and ammonia nitrogen dual-indicator measurement devices, installed at the corresponding seven locations.

[0032] After using the sewage continuous measurement device, install the control valves (3) of 7 channels, connect them to 7 positions respectively, and record them as (3)-①, (3)-②, ..., (3)-⑦, such as Figure 2 shown.

[0033] Use a timer switch to control the operation of the water pump 2, use a timer switch to control the drain outlet of the sampling box 1, use a timer switch to control the 7 control valves 3, and design the switch times as shown in the following table:

[0034]

[0035] As can be seen from the table, the COD and ammonia nitrogen value readings of the measuring instrument at 7:15 are ① the instantaneous values ​​of the water in the biochemical pool, the COD and ammonia nitrogen value readings at 7:45 are ② the instantaneous values ​​in the improved AAO-pre-anoxic pool... and so on. The instantaneous value measurements of 7 points are completed in the 3 hours from 7:00 to 10:00.
