[0018] A sewage treatment intelligent regulation system of the present invention comprises a water information acquisition unit, an output control module and an execution unit.

[0019] The water information acquisition unit of this embodiment monitors the turbidity information, volume information, temperature information, floating body information and pH value information of the sewage to be treated in real time; the water information acquisition unit is also used to monitor the DO data, SS data, COD data, ammonia nitrogen data, total nitrogen data and total phosphorus data of the sewage to be treated. The output control module controls the control execution unit to work according to the parameter conditions detected by the water information acquisition unit.

[0020] The execution unit includes a flocculant control module, a floating body automatic removal module, a reactor control module, a temperature control module, a pH value control module and an aeration volume control module.

[0021] The water information acquisition unit includes a water surface image acquisition unit, an area measurement unit, a water level detection unit, a temperature detector and a pH meter.

[0022] The water information acquisition unit uses the water information acquisition unit to collect images of the water surface to determine whether there are floating debris on the water surface. If the image collected by the image acquisition unit shows that there are floating objects on the water surface, the floating object automatic removal module will work to remove the floating objects on the water surface.

[0023] The automatic floating body removal module of this embodiment includes a scraping module arranged in the regulating tank; the scraping module includes an upper fixed plate, a lower fixed plate and a net body arranged between the upper fixed plate and the lower fixed plate; the scraping module is controlled by a lifting module controller; the lifting module has a transverse movement module to control it to drive the scraping module to move left and right.

[0024] When there are floating objects, the lifting module controls the scraping module to rise, the upper fixed plate is exposed above the water surface and the lower fixed plate is sunk below the water surface. The transverse movement module controls the reciprocating movement of the net body to scoop the floating objects on the water surface into the net body. The lifting mechanism continues to lift and lift the floating objects in the net body out of the water surface and outside the treatment pool. The rotating mechanism on the top of the lifting component rotates to pour out the floating objects in the net body.

[0025] The flocculant control module of this embodiment includes a flocculant selection module, a flocculant automatic addition module and a flocculant dosage adjustment module; the flocculant selection module selects an inorganic flocculant or an organic flocculant according to the water quality information monitored in real time by the water information acquisition unit; when the water information acquisition unit determines whether flocculant needs to be added according to the received turbidity information, the flocculant automatic addition module is started when flocculant needs to be added; at the same time, when the flocculant control module determines that the organic matter content is small according to the received information, the flocculant selection module selects an inorganic flocculant for addition, and the flocculant dosage adjustment module adjusts the flocculant dosage according to the size of the turbidity information and the water volume information; when the flocculant control module determines that the organic matter content is large according to the received information, the flocculant selection module selects an organic flocculant for addition, and the flocculant dosage adjustment module adjusts the flocculant dosage according to the size of the turbidity information and the water volume information.

[0029] When the reactor is working, the power remains constant. For water bodies with poor water quality, purification is incomplete. For water bodies with good water quality, the reactor continues to work, resulting in energy loss.

[0031] The temperature regulation module of this embodiment includes a temperature detector, a heating device and a cooling water circulation pipeline; the temperature detector feeds back the measured temperature data to the output control module. When the temperature data exceeds the threshold, the cooling water in the cooling water circulation pipeline flows faster to cool down. When the temperature data is lower than the threshold, the heating device works to increase the temperature.

[0032] The pH value adjustment module of this embodiment includes a pH meter, an acid delivery pipeline and an alkali delivery pipeline; the output control module controls the acid delivery pipeline or the alkali delivery pipeline to deliver acid or alkali according to the acquired pH value information, so that the pH value reaches the preset requirements.
