FIG. 9 is a schematic perspective view of an intelligent monitoring device of the process wastewater treatment system of the present invention; it will be appreciated by those skilled in the art that the schematic is illustrative and is not intended to limit the actual form of the present invention.

The specific use of the apparatus and method of the present invention is generally described as follows:

step 1: the operator may place the intelligent monitoring apparatus 200 of the present invention into an initial position, which may be located in the wastewater composition monitoring tank, and/or the first treatment apparatus, and/or the second treatment apparatus, by a transportation apparatus, such as a small crane or the like;

step 2: according to the environmental parameters to be monitored, the position parameters are input into a microcomputer in advance, and the microcomputer transmits instructions to the corresponding devices;

for example, the intelligent monitoring apparatus 200 is submerged to a predetermined depth, for example, 20 meters, or 30 meters, 40 meters, 50 meters, 60 meters, 70 meters, by controlling the microcomputer to transfer the depth information of the dive to the auxiliary submergence apparatus so that the capsule is inflated or deflated.

For example, the traveling direction is transmitted to a small steering engine by controlling a microcomputer, so that the steering engine deflects at a preset angle, and the traveling direction is adjusted;

for example, the traveling speed of the intelligent monitoring equipment is controlled by controlling the microcomputer to travel to a preset position, and the general direction of the intelligent monitoring equipment can be known through the feedback of the position sensor and the depth sensor until the intelligent monitoring equipment moves to the preset position;

step 3: when reaching a predetermined position, for example, a position of 25 m deep in the sewage component monitoring tank, 30 m in the width direction and 40 m in the length direction, the first motor 207 is controlled to push the detection sensing part including the receiving chamber to move outwards (leftwards in the drawing) relative to the whole holder, as shown in fig. 2, so that the receiving chamber inlet 2053 is exposed to the sewage environment, and thus the sewage can enter the receiving chamber 2051 through the inlet, and the fine filter 2054 can filter out particulate matter impurities, thereby protecting the detection sensor 2052 and prolonging the service life thereof; at this time, the detecting sensor 2052 starts to work, detects the components of the sewage flowing through it, feeds back the detection result to the microcomputer, and then transmits back to the control terminal for reference by researchers;

step 4: when the detection operation can be stopped, the accommodating cavity 2051 can retract into the retainer 203 under the drive of the first micro motor 207;

step 5: when the sampling collector is required to collect, the third micro motor 2082 is started to push the piston rod to drive the piston 2083 and the sampling collector 209 to move outwards (to the right in the drawing), so that the protruding portion 2095 and the recessed portion 2085 are separated; when the third micro-motor pushes the piston 2083 to a predetermined position, the fourth micro-motor 2099 may be activated to rotate the sample collector 209 to collect the sample.

Step 6: when the sampling is finished, the control terminal sends an instruction to a microcomputer, and the microcomputer controls corresponding equipment, so that the intelligent monitoring equipment 200 floats to the water surface, automatically returns to the initial position, is recovered by an operator through the transportation equipment, and takes out a sample in the sampling collector.

The system and the method of the invention can obtain the following beneficial effects:

the treatment modes are various and selectable, so that the sewage can be treated in a targeted manner according to the monitoring result, and the effectiveness of treatment is improved;

the monitoring sensing device is hidden, so that relatively large corrosion can be tolerated, and the service life is prolonged;

-a sample of sewage can be freely collected for subsequent analysis and treatment;

alternatively, with flexible chain sensors, monitoring data can be transmitted truly and reliably, also facilitating recycling of the probe head and the sampling collector.
