[0036] Working principle of this utility model:

[0037] The oily wastewater from kitchen washing is separately collected through the pipe network and enters the septic tank area 200 after pretreatment in the oil separation area 100. After being mixed with the toilet flushing sewage, it successively enters the first compartment 201, the second compartment 202, and the third compartment 204 of the septic tank area 200. After nearly 24 hours of septic pretreatment, the solids, refractory, and macromolecular organic matters in feces, urine, and kitchen washing sewage are converted into dissolved, easily degradable, and small-molecular organic matters. While removing a small amount of organic pollutants, the biodegradability of the sewage is greatly improved. When the septic tank operates for more than half a year, it is necessary to regularly suck and clean the inorganic substances deposited at the bottom of the first compartment. The supernatant of the third compartment 203 flows into the subsequent anaerobic area 300 by gravity. Under the action of the filler microorganisms in the anaerobic area 300, the biodegradability of the organic matters in the sewage is further improved, and the macromolecular refractory organic matters are converted into easily degradable small-molecular substances. After anaerobic treatment, the sewage enters the aerobic area 400 for high-efficiency treatment. Under the aeration condition, dissolved oxygen is provided for the sewage, greatly increasing the reproduction and degradation speed of the microorganisms in the sewage. Under the synergistic action of ammonifying bacteria, nitrite bacteria, and nitrifying bacteria, the organic nitrogen compounds in domestic sewage are converted into NO2--N and NO3-N, and BOD5 is removed. The easily degradable small-molecular organic matters are converted into pollution-free CO2 and H2O, and phosphorus is absorbed and utilized under the action of the nitrifying bacteria inside the filler, completely avoiding the black and odorous phenomenon caused by sewage discharge. Different types of fillers are placed in the anaerobic area 300 and the aerobic area 400, which can increase the types and quantities of microorganisms. Compared with the conventional activated sludge method, the biological treatment efficiency of the sewage tank is greatly improved. There is a clean water reuse area 500 in the biochemical area. In arid areas in the west or north, the treated sewage can be stored and reused for farm crop irrigation at any time. In order to prevent farmers from stopping using due to the power consumption of the normal use of the aeration equipment, a solar photovoltaic power supply system will be adopted. Under the condition of ensuring the normal operation of the sewage treatment equipment, there is no need to pay the equipment operation electricity cost separately every month, solving the worries of the common people, ensuring the normal operation of the sewage treatment equipment, and completely solving the problem of the normal operation of the sewage treatment equipment.
