Set up back flush equipment 2 through the water inlet 11 department at clarification tank 1 for wash the dirty that 1 water inlet 11 of clarification tank blockked, guarantee that clarification tank 1 can stabilize quick intake, the back flush setting that sets up at 1 delivery port 12 of clarification tank equally is arranged in clearing up owing to salvage the delivery port 12 that does not thoroughly lead to the jam for the produced flocculation thing of purifying sewage in clarification tank 1, guarantees the drainage of clarification tank 1, and then guarantees the normal use of whole clarification tank 1.
The backwashing equipment 2 is a backwashing filter, and is provided with a first backwashing filter 21 at the water inlet 11 and a second backwashing filter 22 at the water outlet 12.
The back washing filter is a precise device which directly intercepts impurities in water by using a filter screen, removes suspended matters and particles in the water body, reduces turbidity, purifies water, reduces the generation of system dirt, bacteria, algae, rust and the like, and purifies the water and protects other devices of the system to normally work. Water enters the self-cleaning filter body from the water inlet 11, and due to the intelligent design (PLC10 and PAC), the system can automatically identify the impurity deposition degree and automatically discharge sewage by giving a signal to a sewage discharge valve.
The first backwashing filter 21 arranged at the water inlet 11 is used for backwashing the valve at the water inlet 11 of the clarification tank 1 and a filter screen at the valve, so that normal sewage inlet of the clarification tank 1 is ensured; the same second backwashing filter 22 arranged at the water outlet 12 of the clarification tank 1 performs backwashing on flocculates intercepted by the valve and the filter screen at the water outlet 12, so as to ensure the normal drainage of the clarification tank 1.
Be provided with grid machine 3, coagulating mixer 4 and flocculation mixer 5 in the depositing reservoir 1, coagulating mixer 4 and flocculation mixer 5 all are connected with charge device 6, and the water inlet 11 and the delivery port 12 punishment of depositing reservoir 1 are provided with a PH detector 7 respectively. The dosing device 6 is divided into a sodium carbonate dosing device 61 and a lime milk dosing device 62, wherein the sodium carbonate dosing device 61 is used for supplying the coagulation mixer 4, and the lime milk dosing device 62 is used for supplying the flocculation mixer 5.
PLC10 reachs the sewage pH valve of entering according to the PH detector 7 of 1 water inlet 11 department in clarification tank, and then according to the corresponding sodium carbonate of this pH valve configuration and lime breast, and add coagulating stirrer 4 and flocculation mixer 5 respectively through sodium carbonate charge device 61 and lime breast charge device 62 among the control charge device 6, and carry out abundant mixing with sewage and realize the purpose of decontamination, the PH detector 7 of later exit is used for detecting the sewage pH valve that needs outer row and accords with emission standard, if do not accord with PLC10 control valve and do not open, continue to carry out sewage purification, until after according with the standard, the valve is opened and is discharged. Wherein the grating machine 3 is used for salvaging floccules formed after the sewage is purified in the clarification tank 1 and purifying the sewage.
The clarification tank 1 is provided with a liquid level sensor 8 at a high water level, an inclined sewage draining channel 13 is further arranged at the bottom of the clarification tank 1, and a sewage draining pump 9 is arranged in the sewage draining channel 13.
The PH detectors 7 of the water inlet 11 and the water outlet 12, the dosing device 6, the liquid level sensor 8 and the sewage pump 9 are all connected with the PLC10 and are used for automatically controlling the dosing amount and the dosing sequence of the dosing device 6 according to the PH detectors 7 of the water inlet 11 and the water outlet 12 and automatically controlling the sewage discharge amount of the sewage pump 9 according to the liquid level of the liquid level sensor 8.
In the embodiment, PLC10 is arranged in the whole sewage treatment station as the core of the whole intelligent control, so that PLC10 obtains the pH value of the entering sewage according to a pH detector 7 at a water inlet 11 of a clarification tank 1, and then configures corresponding sodium carbonate and lime milk according to the pH value, and adds a coagulation stirrer 4 and a flocculation stirrer 5 respectively by controlling a sodium carbonate dosing device 61 and a lime milk dosing device 62 in a dosing device 6, and fully mixes with the sewage to realize the purpose of decontamination, then the pH detector 7 at an outlet is used for detecting that the pH value of the sewage needing to be discharged meets the discharge standard, if the pH value does not meet the PLC10 control valve, the sewage purification is continued, the valve is opened to discharge after the pH value meets the standard, a liquid level sensor 8 senses the water level in the clarification tank 1, and when the water level in the clarification tank 1 reaches the position of the liquid level sensor 8, the PLC10 starts the sewage pump 9 to discharge and clean the sediment at the bottom of the clarification tank 1.
The working principle and the using process of the utility model are as follows: after the device is installed, when sewage enters the clarification tank 1 from the water inlet 11 of the clarification tank 1, the PH value of the sewage is detected by the PH detector 7 positioned at the water inlet 11, the detected data is sent to the PLC10, the PLC10 sets the amount of sodium carbonate and lime milk to be added in the medicine adding device 6 according to the detected PH value, then the sodium carbonate medicine adding device 61 is controlled to add the sodium carbonate into the coagulating mixer 4, so that the coagulating mixer 4 fully stirs and mixes the sodium carbonate and the sewage, meanwhile, the lime milk medicine adding device 62 adds the lime milk into the flocculating mixer 5, the lime milk is mixed with the sewage by the flocculating mixer 5, the sewage in the clarification tank 1 is purified, simultaneously, precipitable impurities in the sewage are precipitated at the bottom of the clarification tank 1 and slide down to the sewage discharge channel 13 along the bottom to be precipitated until the liquid level in the whole clarification tank 1 is raised finally, until the water level sensor 8 detects the water level, the PLC10 controls the sewage pump 9 to discharge the sediment in the sewage discharge channel 13, the flocculated matter formed by the sewage in the clarification tank 1 is salvaged by the grating machine 3, the clarified water is discharged from the water outlet 12 after being detected to be qualified by the PH detector 7 at the position from the water outlet 12 of the clarification tank 1, and the unqualified water is processed in the clarification tank 1 continuously.
After long-term use, valves and intercepting nets at the water inlet 11 and the water outlet 12 of the clarification tank 1 are blocked by a large amount of dirty flocculates and flocculates which are not fished out completely, at the moment, the first backwashing filter 21 in the backwashing equipment 2 is started to perform backwashing cleaning on the water inlet 11 of the clarification tank 1, and the second backwashing filter 22 in the same backwashing equipment 2 is started to perform backwashing cleaning on the water outlet 12 in the clarification tank 1, so that the clarification tank 1 is ensured to treat sewage smoothly.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
