The wastewater generated by the high tower flushing enters the detection box 7 through the wastewater inlet pipe 8, the controller 2 starts the turbidity detection probe 91 immediately after starting, the emission end of the turbidity detection probe 91 emits light and projects the light to the receiving end of the wastewater, when the turbidity of the wastewater is high, the light irradiated to the receiving end of the turbidity detection probe 91 is reduced because the light is blocked by impurities such as suspended matters, the light intensity of the receiving end of the turbidity detection probe 91 is reduced, the resistance of a photosensitive element in the receiving end of the turbidity detection probe 91 is increased, otherwise, when the turbidity of the wastewater is low, the light intensity of the receiving end of the turbidity detection probe 91 is high, the resistance of the photosensitive element in the receiving end of the turbidity detection probe 91 is reduced, the electric signal intensity output to the controller 2 is synchronously changed (the turbidity detection probe 91 outputs an analog current signal of 4mA to 20mA to the controller 2) due to the turbidity change of the wastewater, when the turbidity of the wastewater is lower than 30%, the analog electric signal output by the turbidity detecting probe 91 to the controller 2 is in the range of 15mA to 20mA, when the turbidity of the wastewater is in the range of 30% to 65%, the analog electric signal output by the turbidity detecting probe 91 to the controller 2 is smaller than 15mA and larger than 9mA, and when the turbidity of the wastewater is higher than 65%, the analog electric signal output by the turbidity detecting probe 91 to the controller 2 is in the range of 4mA to 9mA, the analog electric signal output by the controller 2 is measured by the measurement circuit, when the analog electric signal is in the range of 15mA to 20mA, the shunt electric valve 95 inside the low concentration wastewater shunt pipe 94 is controlled by the controller 2 to be opened by electricity (the shunt electric valve 95 is an electromagnetic valve after being electrified, the valve hole is completely opened), and at the moment, the wastewater with the turbidity lower than 30% enters the low-concentration sedimentation zone 6 through the detection box 7 and the low-concentration wastewater shunt pipe 94, and similarly, the wastewater with the medium concentration and the high concentration enters the medium-concentration sedimentation zone 5 and the high-concentration sedimentation zone 4 respectively through the medium-concentration wastewater shunt pipe 93 and the high-concentration wastewater shunt pipe 92;
After the controller 2 is started, the controller 2 starts three air pumps 103 and a semiconductor refrigerator 108, the air pumps 103 can convey air into the cavity 102 on the same side, under normal conditions, air flow can be discharged through one side of a machine barrel 104 provided with a normally open proportional electromagnetic valve 112 and is sprayed out of a group of air injection heads 107 on the same side through an air discharge vertical pipe 105 and an air discharge transverse pipe 106 on the same side, the air flow sprayed out of the air injection heads 107 can drive the wastewater on the same side to flow, the semiconductor refrigerator 108 (the semiconductor refrigerator 108 comprises a P-type semiconductor material and an N-type semiconductor material, when direct current flows from the N-type semiconductor material to one end of the P-type semiconductor material, electrons are transited from a high-energy conduction band of the N-type semiconductor material to a low-energy valence band of the P-type semiconductor material, and the process needs to absorb energy, so that the cold end temperature is reduced, the refrigerating temperature is about 5 ℃, the air flow sprayed out of each water molecule head 107 can refrigerate the wastewater on the same side, and the thermal movement of water molecules and fertilizer molecules is slowed down, the movement speed of the fertilizer molecules and the dirt dissolution rate of the fertilizer molecules are reduced to a certain extent;
When the measurement circuit of the controller 2 recognizes the analog electric signal output by the turbidity detecting probe 91, the controller 2 outputs corresponding control currents to the corresponding normally open proportional solenoid valve 112 and normally closed proportional solenoid valve 113 according to the analog electric signal range and the preset rule, so that the corresponding normally open proportional solenoid valve 112 and normally closed proportional solenoid valve 113 reversely proportion to the corresponding currents in the range of 0.4A to 2A (by establishing a linear corresponding relationship in advance, the analog electric signal output by the turbidity detecting probe 91 is inversely proportional to the electric signal input to the normally open proportional solenoid valve 112 and the normally closed proportional solenoid valve 113), for example, when the measurement circuit of the controller 2 detects that the analog electric signal output by the turbidity detecting probe 91 is in the range of 15mA to 20mA, the controller 2 controls the normally open proportional solenoid valve 112 and the normally closed proportional solenoid valve 113 above the low concentration sedimentation zone 6 to be synchronously electrified, and when the intensity of the analog electric signal outputted from the turbidity detecting probe 91 to the controller 2 is 20mA, the controller 2 controls the intensity of the electric current to be 0.4A to be supplied to the normally open proportional solenoid valve 112 and the normally closed proportional solenoid valve 113, and when the intensity of the analog electric signal is 15mA, the intensity of the electric current to be supplied to the normally open proportional solenoid valve 112 and the normally closed proportional solenoid valve 113 is 0.9A, when the analog electric signal outputted from the turbidity detecting probe 91 is in the range of 4mA to 9mA, the controller 2 controls the normally open proportional solenoid valve 112 and the normally closed proportional solenoid valve 113 to be synchronously energized, and when the intensity of the analog electric signal outputted from the turbidity detecting probe 91 to the controller 2 is 9mA, the controller 2 controls the intensity of the electric current to be supplied to the normally open proportional solenoid valve 112 and the normally closed proportional solenoid valve 113 to be 1.5A, and when the intensity of the analog electric signal is 4mA, the current intensity of the normally-open proportional electromagnetic valve 112 and the normally-closed proportional electromagnetic valve 113 is 2A, and similarly, when the current intensity is smaller than 15mA and larger than 9mA, the controller 2 can also control the current intensity of the normally-closed proportional electromagnetic valve 113 and the normally-open proportional electromagnetic valve 112 which are arranged above the medium concentration sedimentation zone 5 according to the inverse proportion, namely, the controller 2 controls the corresponding normally-open proportional electromagnetic valve 112 and the normally-closed proportional electromagnetic valve 113 to be electrified according to the magnitude of an analog electric signal output by the turbidity detection probe 91, and controls the current intensity of the normally-open proportional electromagnetic valve 112 and the normally-closed proportional electromagnetic valve 113 according to the magnitude of the analog electric signal in an inverse proportion;
Taking the example that the analog electric signal outputted from the turbidity detecting probe 91 is in the range of 4mA to 9mA, since the higher the turbidity of the wastewater is, the smaller the analog electric signal intensity outputted from the turbidity detecting probe 91 to the controller 2 is, at this time, the larger the current intensity in the normally open proportional solenoid valve 112 and the normally closed proportional solenoid valve 113 above the high concentration sedimentation zone 4 is, and the larger the current intensity in the normally open proportional solenoid valve 112 is, the larger the distance in which the solenoid member in the normally open proportional solenoid valve 112 moves is, the smaller the gap between the valve member and the valve hole is, the smaller the opening degree of the normally open proportional solenoid valve 112 is, and the larger the distance in which the solenoid member in the normally closed proportional solenoid valve 113 moves is, and the larger the gap between the valve member and the valve hole is, so the larger the opening degree of the normally closed proportional solenoid valve 113 is, therefore, when the turbidity of the wastewater is higher than 65%, the higher the turbidity of the wastewater, the lower the opening degree of the normally open proportional solenoid valve 112, and the higher the opening degree of the normally closed proportional solenoid valve 113, so that the gas flow rate through the normally closed proportional solenoid valve 113 increases, and at this time, the higher the gas flow rate measured by the side gas flow meter 114, the gas flow meter 114 can synchronously measure the gas flow rate based on the turbidity of the wastewater, and the turbidity of the wastewater in the corresponding region can be accurately reflected by accumulation through the gas flow rate (although the wastewater can be transported and precipitated in a partitioned manner through the low concentration wastewater shunt tube 94, the high concentration wastewater shunt tube 92 and the medium concentration wastewater shunt tube 93, the turbidity of the wastewater entering each region is still different, for example, when the turbidity of the wastewater entering the low concentration precipitation region 6 is close to 30%, the content of impurities such as suspended solids in the low concentration precipitation region 6 is also at a higher level, the content of flocculation agents which need to be added later is correspondingly increased);
As the turbidity of the washed wastewater gradually becomes lower when the high tower is washed and approaches to the tail sound, when the turbidity of the wastewater is lower than 15%, the measurement circuit of the controller 2 measures that the analog electric signal output by the turbidity detection probe 91 is in the range of 17.5mA to 20mA, the controller 2 controls the normally open drainage solenoid valve 17 to be electrified, at the moment, the electromagnetic part inside the normally open drainage solenoid valve 17 is electrified with enough current to enable the normally open drainage solenoid valve 17 to be completely closed, so that the wastewater discharged through the low-concentration wastewater shunt pipe 94 can temporarily stay in the water storage box 15, the turbidity of the wastewater detected by the turbidity detection probe 91 can be continuously kept lower because the washing of the high tower is relatively clean at the moment, the normally open drainage solenoid valve 17 is continuously closed, the wastewater entering the water storage box 15 can not be timely discharged, and the water pressure inside the water storage box 15 can be increased, after the pressure element of the water pressure detector 18 detects that the water pressure reaches a set value (the set value is set based on the volume of the water storage box 15), the water pressure detector 18 feeds back an electric signal to the controller 2, at this time, the controller 2 sends an electric signal to the handheld terminal (such as a mobile phone, etc.) of the related personnel through the communication module of the controller, the related personnel should stop the cleaning work of the high tower in time, so as to avoid the waste of water resources caused by excessive cleaning (wherein, because of less pollutant attached to certain side walls of the high tower in the flushing of the high tower, the turbidity of part of the wastewater entering the wastewater inlet pipe 8 may be lower, at this time, although the water storage box 15 stores water, the other side walls of the high tower still generate relatively turbid wastewater, so the normally-open water discharge electromagnetic valve 17 cannot be electrified continuously at high frequency, therefore, the water pressure detector 18 does not detect that the water pressure reaches the set value and outputs an electric signal to the controller 2, thereby reducing the possibility of false alarm;
After the controller 2 receives the electric signals output by the water pressure detector 18, the controller 2 controls each liquid level meter 111 to operate, the liquid level meter 111 emits infrared rays to the corresponding area, and calculates the time required for receiving the reflected infrared rays, so as to calculate the liquid level of the corresponding area, and outputs analog electric signals of corresponding magnitude to the controller 2 according to the liquid level (the liquid level is in the range of 0 meters to 4 meters, the output analog electric signals are in the range of 0mA to 20mA, the higher the liquid level is, the greater the intensity of the analog electric signals output by the liquid level meter 111 to the controller 2 is), the controller 2 receives the electric signals output by each gas flow meter 114 after receiving the analog electric signals output by the liquid level meter 111 (the gas flow meter 114 converts the accumulated measured gas flow into the analog electric signals to be output to the controller 2, the gas flowmeter 114 is in the range of 0 cubic meter to 50 cubic meters, the analog electric signal is in the range of 0mA to 20mA, the higher the gas flow rate is, the higher the analog electric signal intensity is output to the controller 2), then, the controller 2 controls the corresponding liquid level electromagnetic push rod 144 and concentration electromagnetic push rod 145 to supply corresponding electric currents according to the received analog electric signal of the liquid level meter 111 and the analog electric signal of the gas flowmeter 114, since the higher the liquid level of the waste water in a certain area is, the larger the waste water volume in the area is, and the higher the gas accumulation flow rate corresponding to the area is, the higher the overall concentration of the waste water in the area is, so the current intensity supplied to the liquid level electromagnetic push rod 144 and the concentration electromagnetic push rod 145 is larger, at this time, the upward moving distances of the two conductive rings 147 are larger (when the analog electric signals output by the liquid level meter 111 and the gas flowmeter 114 are 20mA, the distance of the liquid level electromagnetic push rod 144 and the concentration electromagnetic push rod 145 pushing the same side conductive ring 147 to move upwards is 20cm, and the smaller the analog electric signal is, the smaller the distance of the liquid level electromagnetic push rod 144 and the concentration electromagnetic push rod 145 pushing the same side conductive ring 147 to move upwards is, so that the contact points of the two conductive rings 147 and the U-shaped resistor rod 143 are moved upwards relatively, the length of the part of the U-shaped resistor rod 143 between the two conductive rings 147 is shortened (namely, the length of the two ends of the horizontal part of the U-shaped resistor rod 143 reaching the positions of the two conductive rings 147 is shortened), and after the liquid level electromagnetic push rod 144 and the concentration electromagnetic push rod 145 are electrified, the controller 2 controls the liquid level electromagnetic push rod 144 and the concentration electromagnetic push rod 145 to move the two conductive rings 147, The U-shaped resistance rod 143 is communicated with the connecting loop corresponding to the medicine outlet electric control valve 124, and the connecting loop is electrified for 1 minute at fixed time, at this time, the medicine outlet electric control valve 124 is electrified and opened (the medicine outlet electric control valve 124 is a proportional electromagnetic valve, namely, the opening degree of a valve hole of the medicine outlet electric control valve 124 is larger), when the volume of waste water is larger, and the overall turbidity of the waste water is higher, the upward moving distance of the two conducting rings 147 is larger, at this time, the length of the connecting loop of the U-shaped resistance rod 143 connected with the two conducting rings 147 and the medicine outlet electric control valve 124 is shorter, so that the resistances of the U-shaped resistance rod 143, the two conducting rings 147 and the connecting loop corresponding to the medicine outlet electric control valve 124 are smaller, the current flowing into the medicine outlet electric control valve 124 is larger, the opening degree of the valve hole of the medicine outlet electric control valve 124 is larger, and the flocculation dosage thrown into the area through the discharging pipe 123 and the medicine outlet electric control valve 124 is synchronously increased in the time of 1 minute, otherwise, and when the volume of waste water is lower, the flocculation dosage flowing into the area is synchronously reduced;
After the medicine discharging electric control valve 124 finishes the timing work, the controller 2 controls each semiconductor refrigerator 108 to stop working, controls each normally closed proportional electromagnetic valve 113 to supply enough current, so that the valve hole of the normally closed proportional electromagnetic valve 113 is completely opened, at the moment, the air flow conveyed by the air pump 103 can be sprayed out together through two groups of air spraying heads 107 at the same side, the flocculating agent can be quickly mixed with suspended matters and the like under the driving action of the air flow which flows relatively, after 10 minutes, the controller 2 controls the air pump 103, the normally closed proportional electromagnetic valve 113 and the like to stop working, and waits for flocculation precipitation for 4 hours, the controller 2 controls the sewage discharging electric control valve 133 in the drain pipe 132 in the low concentration precipitation zone 6 to be electrified and opened, at the moment, clean water in the low concentration precipitation zone 6 can be discharged into a next-stage treatment device through the drain pipe 132 and the sewage discharging pipe 131 at the side, after electrifying for 30 minutes, the controller 2 controls the blowdown electric control valve 133 to be powered off and closed, and controls the blowdown electric control valve 133 in the medium concentration sedimentation zone 5 to be powered on and opened after 2 hours, and controls the blowdown electric control valve 133 in the high concentration sedimentation zone 4 to be powered on and opened after 30 minutes and 2 hours, so that the sedimentation work of the fertilizer waste water generated by the whole high tower flushing is finished (the time for flocculation sedimentation is short because the whole turbidity of the waste water in the low concentration sedimentation zone 6 is low, the waste water can be quickly sedimented and preferentially enters the next process, the waste water in the medium concentration sedimentation zone 5 is secondary, and the waste water in the high concentration sedimentation zone 4 is finally discharged into the next process), and through the partition sedimentation and discharge, the dissolution and diffusion of the fertilizer can be avoided, the treatment difficulty of the next process is reduced, and the treatment efficiency of the whole waste water is improved (wherein the low concentration sedimentation zone 6 is a low concentration sedimentation zone 6, the sedimentation time and the drainage interval in the medium concentration sedimentation device 5 and the high concentration sedimentation zone 4 can be adjusted by the controller 2).
The foregoing description of the preferred embodiments of the invention is not intended to limit the invention to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the invention are intended to be included within the scope of the invention.
