For example: when the total phosphorus of intaking of cell body exceeds standard, the total phosphorus of intaking of cell body matches with the emergent parameter range of presetting the parameter range this moment, and the addition of the PH regulator through control medicine system is with the pH value of adjustment biological pond to target PH scope, control sludge pump with the mud discharge volume that increases the secondary sedimentation pond, control medicine system and put into the dephosphorization agent to biological pond and control medicine system and put into the dephosphorization agent to high-efficient sedimentation tank and carry out effectual dephosphorization.

Alternatively, carbon sources include, but are not limited to, acetic acid, methanol, sodium acetate, and the like.

In the conventional common activated sludge process, the CNP ratio is 100:5:1, TP is excessive in actual sewage treatment, and many TP needs to be matched with chemical phosphorus removal to reach the standard, so that a carbon source calculated by TP is large, and the addition amount of the carbon source is calculated by the total amount of nitrogen and ammonia in the embodiment of the invention:

cm 20N-C (formula 1)

Wherein Cm is the amount (calculated by COD) mg/l of an external carbon source which needs to be added, 20 is CN ratio, and the weight ratio is 100: 20, N is the amount of NH3 to be removed, and the unit is mg/l, C is the carbon source difference of inlet water (carbon source) and outlet water (carbon source) of the cell body, and the unit is mg/l, and the amount of nitrogen to be removed is calculated as follows:

N-Ne-Ns (formula 2)

Wherein Ne is the actual NH3 amount of inlet water and the unit is mg/l, and Ns is the preset NH3 emission index amount of outlet water and the unit is mg/l.

Calculating the difference value of the carbon sources of inlet and outlet water:

c ═ Ce-Cs (formula 3)

Wherein Ce is the actual inlet water chemical oxygen demand of the tank body (such as an inlet tank), and Cs is the preset outlet water chemical oxygen demand of the tank body, and the units are mg/l.

Ne and Ns are 45 and 5, respectively, and N-Ne-Ns-45-5-40 (mg/L), Ce and Cs are 180 and 50, respectively, C-Ce-Cs-180-50-130 mg/L, and Cm-20N-C-20 × 40-130-670 (mgCOD/L).

Assuming that the wastewater treatment water quantity Q is 181000m ³ D, the COD amount needs to be added every day:

Cd＝QCm＝1.81×10^4×670×10^-3＝12127(kgCOD/d)

if the carbon source is acetic acid and the COD equivalent is 1.07kgCOD/kg, the amount of acetic acid corresponding to the amount of the added carbon source is as follows: 12127/1.07 ═ 11333.6 kg/d; if the carbon source is methanol, the COD equivalent is 1.5kgCOD/kg, and the amount of methanol corresponding to the amount of the added carbon source is as follows: 12127/1.5 is 8084.6kg/d, namely, the system inputs the calculated relation logic, then selects the type of the external carbon source used in the sewage treatment plant according to the inlet water COD monitored by the inlet water quality monitor, the inlet water NH3 and the current water volume of the biological pond, calculates the carbon source amount to be added, and then controls the dosing module to accurately dose the carbon source. It should be noted that the COD equivalent of the carbon source is understood to mean the milligrams of oxygen required per unit volume or per unit mass of the carbon source after all the carbon source has been oxidized, in mg/L, mg/g or mg/kg, and the type, inventory, COD equivalent and other information of the added carbon source can be introduced or inputted into the system.

S350, when the water inlet suspended matter of the tank body is matched with the preset parameter range, executing a fifth emergency treatment scheme: and controlling a sludge pump to increase the sludge discharge amount of the high-efficiency sedimentation tank, controlling a dosing system to increase the dosing amount of PAC and PAM to the high-efficiency sedimentation tank, increasing the internal circulation of the high-efficiency sedimentation tank and flushing at least one of inclined pipes of the high-efficiency sedimentation tank.

For example: the suspended solid of intaking of cell body exceeds standard, and the suspended solid of intaking this moment matches with the emergent parameter range of predetermineeing the parameter range, and the mud pump is washed the pipe chute of high-efficient sedimentation tank in order to increase the sludge discharge of high-efficient sedimentation tank, control medicine system increase PAC, PAM's the medicine volume of adding to high-efficient sedimentation tank, increase the inner loop of high-efficient sedimentation tank and control back flush system by turns when the water yield is less than the threshold value to improve the treatment effect to the suspended solid of intaking. It should be noted that, in other embodiments, the sludge pump may be controlled to increase one or more of the sludge discharge amount of the high-efficiency sedimentation tank, the chemical dosing amount of PAC and PAM added to the high-efficiency sedimentation tank by the chemical dosing system, the internal circulation of the high-efficiency sedimentation tank is increased, and the inclined pipe of the high-efficiency sedimentation tank is flushed.

The PAC is polyaluminium Chloride (polyaluminium Chloride), has the performances of adsorption, coagulation, precipitation and the like, is poor in stability and corrosive, the water purification process of the polyaluminium Chloride is generally divided into three stages, namely a coagulation stage, a flocculation stage and a sedimentation stage, the coagulation stage can form fine alum flocs in a very short time when liquid medicine is injected into a coagulation container and raw water is rapidly coagulated, and at the moment, a water body becomes more turbid and requires water flow to generate violent turbulence. And then, allowing the polyaluminium chloride to enter a flocculation stage, wherein the flocculation stage is a process of thickening the growth of alum flocs, and requires proper turbulence degree and enough retention time (10-15 min), and a large amount of alum flocs can be observed to slowly sink to form a clear surface layer at the later stage. When the flocculating agent is in a sedimentation stage, the flocculating agent is a flocculation sedimentation process in a sedimentation tank, the water flow is required to be slow, an inclined tube or plate type settler is generally adopted for improving the efficiency, a large amount of large alum flocs are blocked by the wall of the inclined tube (plate) and are deposited at the bottom of the tank, the upper layer water is clear water, the remaining alum flocs with small particle size and small density slowly descend, collide with each other continuously and are large, and the remaining turbidity is basically unchanged in the later period. PAM is polyacrylamide, which is a general name of acrylamide homopolymer or polymer obtained by copolymerizing with other monomers, and in sewage treatment, the use ratio of water recycling cycle can be increased by adopting polyacrylamide, and the PAM can also be used for sludge dewatering; (2) the water quality is improved, and the water quality can be obviously improved by matching the polyacrylamide and the inorganic flocculant in the drinking water treatment and the industrial wastewater treatment; (3) the strength and the settling rate of the flocs are improved, and the strength of the flocs formed by polyacrylamide is high, and the settling performance is good, so that the solid-liquid separation speed is improved, and the sludge dewatering is facilitated; (4) the use of polyacrylamide can greatly reduce the dosage of inorganic flocculant, thereby avoiding the deposition of inorganic substances on the surface of equipment and slowing down the corrosion and scaling of the equipment.

S360, when the water inlet amount of the water inlet pool is matched with the preset parameter range, executing a sixth emergency treatment scheme: the method comprises the steps of controlling a water pump to be opened according to the water inlet amount of a water inlet tank so as to increase the number of water pumps in a working state, controlling a dosing system to add a coagulant into a primary sedimentation tank, controlling an aeration module to reduce the aeration amount of a biological tank, controlling a sludge pump to increase the sludge discharge amount of a secondary sedimentation tank, controlling the sludge pump to increase the sludge discharge amount of a high-efficiency sedimentation tank, controlling the sludge pump to reduce the sludge reflux amount of the secondary sedimentation tank, and controlling the sludge pump to reduce the sludge reflux amount of the high-efficiency sedimentation tank.

For example: the normal range inlet and outlet water quality standard parameter range is shown in the following table 1:

TABLE 1

Suppose that the amount of wastewater Q to be treated is 181000m ³ D, preset coefficient of variation Kz is 1.16

Designing the maximum inlet water flow Qmax Q Kz 209960m ³ /d＝8748.3m ³ /h＝2.43m ³ And s.
