The derivation process of the beneficial effect is substantially similar to the derivation process of the beneficial effect brought by the automatic control equipment of the agricultural sewage equipment based on the AIoT, and therefore, the description is omitted here.
The automatic control method of the agricultural sewage equipment is specifically described by combining a specific embodiment as follows:
the maximum water inflow of the agricultural sewage treatment facility is assumed to be 24 tons/day, and the maximum water inflow speed is 5 tons/hour. In the actual operation process, the water inlet speed is required to be ensured to be less than or equal to 5 tons/hour, the maximum water inlet amount per hour is less than or equal to 1 ton, and the maximum water inlet amount per day is less than or equal to 24 tons. The minimum value of the dissolved oxygen content in the water in the aerobic tank is 1mg/L, the maximum value is 6mg/L, and the dissolved oxygen content is maintained in the range of 4-6mg/L when the water inflow is normal (namely, when the agricultural pollution treatment facility is in a normal water treatment state).
When the inflow water flow rate is more than 5 tons/hour, the AIoT control module 2 controls the inflow water pump to adjust the frequency, reduces the inflow water flow rate and simultaneously starts the inflow water reflux pump so as to adjust the inflow water flow rate to be less than or equal to 5 tons/hour.
When the water inlet pump operates, the water inlet amount is recorded by taking 60 minutes as a time period, when the water inlet amount in one period is close to 1 ton, the AIoT control module 2 controls the water inlet pump to carry out frequency conversion to gradually reduce the water inlet flow speed, and the water inlet pump is closed when the total periodic water inlet amount reaches 1 ton.
When the water inflow amount and the water inflow flow rate reach the designed maximum values and the water inflow reflux pump is started and the dissolved oxygen content in water is lower than 4mg/L, the AIoT control module 2 controls the main aeration device and the auxiliary aeration device to be started synchronously, and the dissolved oxygen content is maintained in the range of 4-6mg/L by adjusting the opening degrees of the main aeration device and the auxiliary aeration device.
When the water inlet amount is in a normal range (namely, less than a first set value and more than or equal to a second set value), the AIoT control module 2 controls to only start the main aeration device and adjust the opening degree, so that the content of the dissolved oxygen is maintained in a range of 4-6 mg/L.
When the water inflow amount is low or water does not flow in for a long time, the AIoT control module 2 controls to only start the auxiliary aeration device and adjust the opening degree, so that the dissolved oxygen content is maintained at about 1 mg/L. The agricultural waste treatment facility enters a microorganism low activity stage, and necessary microorganism flora is reserved.
When the effluent quality parameters meet the discharge conditions, the AIoT control module 2 starts a reflux water pump to reflux the effluent which does not reach the standard in the effluent pool, and performs secondary treatment to improve the effluent quality until the water quality in the effluent pool reaches the discharge conditions. The AIoT control module 2 can automatically control the reflux quantity and the reflux time according to the effluent quality parameters, if the effluent quality parameters exceed the standard, the reflux quantity is large, the reflux time is long, otherwise, the reflux quantity is small, and the reflux time is short.
Particularly, when the water quality parameters of the discharged water do not meet the discharge conditions, the reflux water pump is started, the water pump of the discharged water is in a stop state, and the water pump of the discharged water is started only when the water quality parameters of the discharged water meet the discharge conditions so as to discharge the water to reach the standard to the natural water body.
When the water inflow amount is gradually reduced or maintained at a low level, the AIoT control module 2 can automatically adjust the maximum water inflow amount per hour and the water inflow flow rate of the agricultural treatment facility so as to reduce the number of biological floras, realize long-time stable operation and avoid the occurrence of the situation of sudden increase or sudden decrease of the floras.
When the inlet water amount is maintained below 20% of the set inlet water amount for a long time, the AIoT control module 2 automatically judges that the agricultural treatment facility enters a low activity state, and the aim is to retain necessary strains at the moment. Through the combined coordination control of aeration, water inlet, backflow and water outlet, organic substances in the water body are fully consumed, the water inflow is reasonably adjusted, the purpose of cultivating strains for a long time is achieved, and the low activity state of the system is maintained.
When water is normally fed, the AIoT control module 2 can automatically adjust the water feeding amount, gradually improve the activity of system strains, shorten the response time of facilities and greatly reduce the bacteria culture time.
It should be noted that the AIoT control module 2 does not control the state of a certain agricultural sewage treatment facility independently, all the agricultural sewage treatment facilities are linked, and specifically, the linkage state of each facility has the AIoT control module 2 to perform unified regulation and control through an artificial intelligence algorithm and an autonomous intelligent control logic formed by continuous learning optimization, so as to achieve the purpose of enabling the agricultural sewage treatment facility to be in the most appropriate sewage treatment state with the best energy consumption.

The multiple schemes provided by the invention comprise basic schemes, are independent from each other and are not restricted with each other, but can be combined with each other under the condition of no conflict, so that multiple effects are realized together.
