According to the invention, precipitation information is collected, and the precipitation is combined with sewage treatment by taking the pH value as an index, so that the problem of nitrogen and phosphorus removal efficiency reduction in sewage treatment caused by precipitation is effectively reduced, and meanwhile, the condition that the load of a sewage treatment plant exceeds the standard caused by excessive precipitation is avoided, and the quality of effluent is further influenced, thereby effectively improving the robustness of a sewage treatment system.
Wherein, the precipitation amount is calculated in mm, and the flow rate is calculated in m/h.
Specifically, in step S2, the sewage treatment system includes a piping unit and a treatment unit;
wherein, the precipitation entering the pipeline unit is of a first type bearing capacity, and the precipitation entering the treatment unit is of a second type bearing capacity;
for single precipitation, the first type bearing capacity, the second type bearing capacity and the normal processing capacity form precipitation sewage, and the difference value between the bearing capacity threshold value of the processing unit and the precipitation sewage is equal to the value of the excess bearing capacity;
wherein the first bearing capacity is positively correlated with the main pipe diameter of the pipeline unit; the second bearing capacity is positively correlated with the footprint of the processing unit; the constant treatment capacity is the average sewage treatment capacity of the treatment unit corresponding to the duration of single precipitation.
By utilizing the precipitation classification mode, the precipitation falling into the open-air sewage treatment facility is calculated independently, so that the prospective of the performance estimation of the sewage treatment system is effectively improved, and meanwhile, the robustness of the sewage treatment system is further improved.
In practice, for example, a sewage plant capable of handling 50000m of water per day, the duration of a single precipitation is 24 hours:
in summer, 35000m of sewage needs to be treated every day:
if the first bearing capacity of the single precipitation duration is 20000m, the second bearing capacity is 4000m, the sum of the first bearing capacity and the daily required treatment capacity of 35000m is 59000m, the first bearing capacity is 9000m, namely the excess bearing capacity;
in spring, 42000m of sewage needs to be treated every day,
if the first bearing capacity of the single precipitation duration is 20000m, the second bearing capacity is 4000m, the sum of the first bearing capacity and the required daily treatment capacity of 42000m is 68000m, the first bearing capacity is 18000m, and the second bearing capacity is the excess bearing capacity;
in winter, 48000m of the sewage needs to be treated every day,
if the first bearing capacity of the single precipitation duration is 12000m, the second bearing capacity is 2000m, the sum of the first bearing capacity and the 48000m of daily required treatment capacity is 62000m, and the 12000m bearing capacity is the excess bearing capacity.
Specifically, in step S3, the precipitation treatment method is divided into a diversion treatment and a cutoff treatment, and for a single precipitation,
if the sum of the second class bearing capacity and the normal processing capacity is smaller than the bearing capacity threshold value, adopting a diversion processing mode for precipitation processing;
if the sum of the second type bearing capacity and the normal handling capacity is greater than or equal to the bearing capacity threshold value, adopting a cut-off treatment mode for precipitation treatment;
the diversion treatment is to connect the pipeline unit with the treatment unit and treat precipitation corresponding to the first bearing capacity by using the treatment unit;
the cut-off process is to isolate the piping unit and the processing unit from each other.
It is understood that the load threshold is related to the maximum daily throughput of the sewage treatment plant.
It can be understood that the second type of bearing capacity directly enters the sewage treatment plant, which is the bearing capacity of the outdoor equipment affected by precipitation, and the load cannot be avoided during treatment, so that the regulation and control of the first type of bearing capacity is an effective control means for the sewage treatment system.
Specifically, in step S4, the wastewater treatment system is discharged to a predetermined river at the end, and for a single precipitation,
if the pH value of the single precipitation is within the allowable range of the pH value of the preset river, the sewage corresponding to the excessive bearing capacity does not enter the sewage temporary storage pool;
if the single precipitation exceeds the allowable range of the pH value of the preset river, sewage corresponding to the excess bearing capacity enters a sewage temporary storage pool;
wherein the allowable range is related to the flow rate of the preset river.
In the implementation, the sewage with the thickness of 50000m is treated every day as an example, the sewage discharged every day is 35000m,
if the annual average flow of the corresponding discharged river is 1000 m/s, the allowable range can take a value of + -3;
if the annual average flow rate of the corresponding discharged river is 500 m/s, the allowable range can take a value of +/-1;
if the annual average flow of the corresponding discharged river is 1500 m/s, the allowable range can take any value, and the discharge standard is met.
It will be appreciated that the annual average flow of a river is related to the environmental load bearing capacity.
Specifically, in step S5, for a single precipitation, if the corresponding excess load of sewage enters the sewage temporary storage pool, determining a sewage temporary storage mode according to the precipitation treatment mode, wherein,
if the single precipitation treatment mode is cut-off treatment, the sewage temporary storage pool stores in a full-load temporary storage mode;
if the single precipitation treatment mode is diversion treatment, the sewage temporary storage pool stores in a conventional temporary storage mode.
By classifying the precipitation and treating according to the classification, the resource utilization rate is effectively improved, and meanwhile, the problem of secondary pollution caused by overlarge precipitation is avoided, so that the robustness of the sewage treatment system is further improved.
Specifically, in step S5, the sewage temporary storage tank is divided into a path temporary storage tank and a terminal temporary storage tank;
for the full-load temporary storage mode, the path temporary storage pool and the tail end temporary storage pool are opened to bear the excessive bearing capacity;
for the conventional temporary storage mode, the path temporary storage pool is opened and the tail end temporary storage pool is closed, and when the path temporary storage pool is full of sewage, the tail end temporary storage pool is opened to bear the excessive bearing capacity.
Specifically, in step S1, the sampling positions of the precipitation amount information and the ph information are both the pipe unit ends in the processing unit.

It is understood that the temporary storage unit is a pool which can whisker a certain amount of precipitation;
the path temporary storage unit generates evaporation and infiltration when stored, and the path temporary storage unit should be discharged into a sewage pipeline after being stored for a certain period of time so as not to pollute the nearby environment.
