collecting kitchen waste at each community waste classification collection station, pouring the kitchen waste into a kitchen waste crusher of a kitchen waste integrated septic tank in-situ treatment integrated system, and performing ultrafine grinding (the particle size is below 2 mm) after extrusion; pumping the crushed pasty kitchen waste into a kitchen waste treatment tank by a pump, and adding tap water which is 10 times of the weight of the kitchen waste (the kitchen waste can be diluted by 20-40 times when the pollution index of the kitchen waste is very high); starting a micro-nano aeration device of the micro-nano aeration treatment system, adding bacterial liquid of microorganism efficient nitrifying bacteria QS1 (national microorganism collection center number: 17314) and continuously aerating; about 6-18 hours of treatment, the COD of the kitchen waste crushed sewage can be degraded to 600-1000ppm by 4000-8000ppm after being diluted and put into the kitchen waste crushed sewage; after 30 minutes of sedimentation, starting a solenoid valve at the lower right to discharge the clear liquid above the sediment slag into the septic tank; the clear liquid discharged into the septic tank also contains a certain amount of proliferated QS1 nitrifying bacteria, and pollutants (COD/ammonia nitrogen/total phosphorus/scum and the like) in the septic tank can be continuously degraded in the septic tank (facultative-anaerobic environment); then the sewage is pushed into a sewage pipe network by the sewage tank; finally, the waste water enters a town sewage treatment plant for final treatment and is discharged after reaching the set discharge standard.
The second method comprises the following steps:
when the kitchen waste is treated in situ at the kitchen waste collection and classification part, the septic tank is also treated in place. The clear liquid discharged into the septic tank also contains a large amount of proliferated QS1 nitrifying bacteria, and pollutants in the septic tank (in a facultative-anaerobic environment) can be continuously degraded (COD (chemical oxygen demand) -ammonia nitrogen-total phosphorus/scum decomposition/mosquito and fly removal/methane and hydrogen sulfide generation and other flammable and explosive toxic gases under the anaerobic environment) in the septic tank; the treated liquid can stably reach 300-450ppm of COD in the third grid of the septic tank, the water in the third grid of the septic tank enters the kitchen waste treatment tank through the return pipe, the nitrifying bacteria circulate to treat the sewage, and the treated water stably reaches the sewage pipe network storage standard and is pushed into a sewage pipe network; finally, the waste water enters a town sewage treatment plant for final treatment and is discharged after reaching the set discharge standard. And finally, arranging a COD (chemical oxygen demand) online monitoring sensor at the position where the third grid of the septic tank flows into the sewage pipe network, and displaying the effluent standard state on the integrated machine in real time.
The third method comprises the following steps:
the third grid water of the septic tank is pumped back to the first grid through the flow pipe to circulate.
The system can automatically control the operation of each valve, the water level controller and the pump through the control of the electric control system to realize automatic control. The pump in the micro-nano aeration treatment system can be controlled to realize intermittent aeration. The kitchen waste crusher discharge hole is equipped with inductive sensor, through the action of response blowing, gives electrical system with the signal transmission, and the kitchen waste crusher does not open, and after stopping the blowing, the kitchen waste crusher received the signal, and the kitchen waste crusher opens.
When the kitchen waste treatment tank is treated by combining microorganisms with an aeration device, an automatic feeding device is adopted to automatically add microorganism high-efficiency nitrobacteria QS1 into the tank, when the microorganism treatment is not adopted, another form can be adopted, the air inlet pipe of the micro-nano aeration device is connected with an ozone generator through a tee joint, the pump of the micro-nano aeration treatment system works, and in the process of pumping liquid, the micro-nano aeration device on the liquid outlet pipe forms vacuum, air and ozone generated by the ozone generator are pumped into the micro-nano aeration device to form micro bubbles, meanwhile, the kitchen waste treatment tank is pumped into the kitchen waste treatment tank by a liquid pump, the position of a liquid inlet pipe and a liquid outlet pipe of the pump is at a certain angle, liquid in the kitchen waste treatment tank forms vortex, and tiny bubbles pumped by the pump have positive charges due to the fact that the particle size is smaller than 50 micrometers, so that a large number of negative ions, especially OH- (hydroxyl free radicals), can be adsorbed on the surface. Under the combined action of the micro-nano aeration device and ozone, a large amount of hydroxyl free radicals can be generated more easily, and micro powder in the kitchen waste treatment tank is treated.

8. The integrated system for the in-situ treatment of the kitchen waste integrated septic tank according to claim 1, wherein the air inlet pipe of the micro-nano aeration device in the micro-nano aeration treatment system (8) is connected with the ozone generator through a tee.
9. The integrated system for the in-situ treatment of the kitchen waste integrated septic tank according to claim 1, wherein the return pipe (16) is connected with the septic tank (2) by two pipelines, one pipeline is inserted into the overflow groove (14) in the third grid (13) of the septic tank (2), the other pipeline is inserted into the bottom of the third grid (13) of the septic tank (2), and the two pipelines are controlled by a valve.
10. An integrated treatment method for in-situ treatment of a kitchen waste integrated septic tank is characterized by comprising the following steps:
1) collecting kitchen waste at waste classification collecting stations in various communities (dining streets, hotels, farmhouses, etc.);
2) pouring the kitchen waste into an extrusion crushing port of an in-situ liquid treatment all-in-one machine, covering a cover, and then automatically rolling and carrying out ultrafine crushing, wherein the particle size is below 2 mm;
3) the crushed pasty kitchen waste is automatically put into an efficient aerobic treatment machine of the all-in-one machine, and then supernatant (or tap water) which is 20-30 times of the weight of the kitchen waste to be treated is automatically extracted from the surface layer of a third grid of the nearby septic tank and enters the treatment machine;
4) starting the micro-nano aeration device, quantitatively sucking high-efficiency nitrifying bacteria QS1 bacterial liquid through an air inlet pipe, and continuously aerating;
5) after about 6-8 hours of treatment, physical treatment is carried out, the COD of the kitchen waste muddy water can be degraded to be within 500-1000ppm from the original 10-20 ppm by 5000-6700ppm after dilution;
6) after 30 minutes of sedimentation, starting a right lower electromagnetic valve to discharge the clear liquid above the sediment slag to enter a first grid of the septic tank;
7) the clear liquid discharged into the septic tank also contains a certain amount of proliferated QS1 nitrifying bacteria, and pollutants (COD/ammonia nitrogen/total phosphorus/scum and the like) in the septic tank can be continuously degraded in the septic tank (facultative-anaerobic environment);
8) then the sewage is pushed by the septic tank to enter a sewage pipe network through a third grid (reaching the nano pipe standard COD < 300- > 500 ppm);
9) finally, the waste water enters a town sewage treatment plant for final treatment and is discharged after reaching the set discharge standard.
