In this embodiment, the first stirrer 120 is turned on to stir the sewage in the first box 100, and the sludge adsorbed on the inner wall of the first box 100 and the sludge precipitated at the bottom of the first box 100 are scraped off to be fused in the sewage, and then the first switch element 110 at the bottom of the first box 100 is turned on, so that the water flows sequentially through the water outlet 101 and the screen assembly 210 into the second box 200, most of the sludge is precipitated in the screen assembly 210, and the primarily filtered water flows are stored in the second box 200. The water source in the second tank 200 is treated by the purifier 410 and then reaches the fourth tank 400, so as to obtain a cleaner water source for life. And sludge settled in the screen assembly 210 is incinerated in the third tank 300.
In this embodiment, the first switching member 110 may adjust the size of the water outlet 101 opened by the PLC controller, so that the sewage slowly or rapidly flows into the second tank 200.
In some embodiments of the present invention, the screen assembly 210 includes a screen 211 and a robot 212 connected to each other, a docking port 201 for communicating with each other is opened on one surface of the second box 200 and the third box 300, the docking port 201 is provided with a second switch 220 for opening and closing the docking port 201, and a diameter of the docking port 201 can pass through the screen 211.

The rest of the smoke to the chimney 330 is treated by the dust remover 340 and then discharged to the air, so that the harmful substances discharged to the air after incineration are reduced to the maximum extent. The utility model builds corresponding flue gas treatment facilities, thereby ensuring the standard emission of the flue gas.
In this embodiment, the PLC controller starts the incinerator, and after obtaining the real-time temperature transmitted by the temperature sensor, the PLC controller can adjust the incineration temperature.
N, P, K contained in the sludge is a nutrient substance necessary for the growth of crops, and the humus in the sludge is a good soil conditioner, so that the application of the sludge to farmlands can improve the soil structure, increase the soil fertility and promote the growth of crops. Because the sludge contains harmful substances such as pathogenic bacteria and parasitic ova, the sludge can be used as an agricultural fertilizer after being properly treated.
Therefore, in some embodiments of the present invention, an acid-base neutralization apparatus is utilized, and the acid-base neutralization apparatus includes a fifth tank 500, the fifth tank 500 being configured to receive the incinerated sludge, the fifth tank 500 being provided with a reagent injector 510 and a water injector 520, and the fifth tank 500 being further provided with a second agitator 530 and a PH probe.
In this embodiment, the number of the reagent injectors 510 is two, and the reagent injectors are respectively used for containing an acidic reagent and an alkaline reagent, the acidic reagent can be prepared by acidifying and mixing sludge in the prior art, adding the acidified and mixed sludge into the sludge, starting the water injector 520 and the second stirrer 530 to stir uniformly to prepare sludge slurry, and heating the sludge slurry and then washing the sludge slurry with water to obtain a mud cake; the alkaline reagent can be lime powder, the lime powder is added into the mud cake and is uniformly stirred, and the dosage of the lime powder is adjusted through a numerical value fed back by a pH probe, so that the pH value of the mud cake reaches 6.5-7.5.
The method can remove heavy metals in the sludge, can ensure the safety of the organic fertilizer prepared from the sludge in agricultural production, eliminates the risk of resource utilization of the sludge, and creates conditions for the agriculture of the sludge.
In some embodiments of the present invention, the water inlet of the fourth tank 400 is provided with an activated carbon filter plate 450, and the activated carbon filter plate 450 can perform a certain adsorption function to primarily filter the water entering the fourth tank 400 from the second tank 200, and then start the purifier 410.
The fourth box 400 is provided with a first filter screen 420 and a second filter screen 430 at intervals, and both are located below the activated carbon filter plate 450, and quartz sand 440 is laid between the first filter screen 420 and the second filter screen 430.
In this embodiment, the diameters of the filtering holes of the first filtering net 420 and the second filtering net 430 are smaller than the diameter of the quartz sand 440, and the filtering of the quartz sand 440 is one of the most effective means for removing suspended matters in water, and is an important unit in advanced wastewater treatment, wastewater reuse and water supply treatment, and the filtering unit is used for further removing flocculated pollutants in water, and achieves the purpose of purifying water through the interception, sedimentation and adsorption of filtering materials.
In some embodiments of the present invention, the fourth box 400 is provided with a water outlet switch 401 connected to the PLC controller, and after the water outlet switch 401 is turned on, a water source is put into the outside for use; the fourth casing 400 is also provided with a fluorescence detector.

The ATP swab contains a reagent which can crack cell membranes, can release ATP in cells, reacts with specific enzyme contained in the reagent to generate light, and then a fluorescence luminometer is used for detecting a luminescence value, wherein the number of microorganisms is in direct proportion to the luminescence value. Because all living cells of organisms contain constant ATP, the ATP content can clearly indicate the residual quantity of microorganisms and other organisms in a water source, and the sanitary condition is judged.
It should be noted that the ATP fluorescence detector is the prior art, and the specific brand model is not limited herein. The water outlet switch 401 is started by the PLC controller, and upper and lower limit values are set for the PLC controller with reference to sanitary standard for drinking water (GB 5749-2006).
