Detailed Description
The following is a detailed description of a preferred embodiment of the invention:
as shown in FIG. 1, the method for treating toilet sewage comprises the steps of:
the method comprises the following steps: the dirt generated in the toilet falls into the first compartment 21 of the toilet device from the toilet bowl 1, and the liquid component in the dirt is separated into the second compartment 22 through the filtering device;
step two: discharging the separated contaminated water in the second compartment 22 to a treatment facility;
step three: carrying out biodegradation treatment or chemical treatment on the sewage in a first treatment box 4 of the treatment device;
step four: and enabling the sewage to flow to the lower treatment tank through an overflow pipe in the current treatment tank, and performing biodegradation treatment or chemical treatment on the sewage in the lower treatment tank.
It should be noted that the sequence of the first step to the fourth step does not represent the limitation of the operation sequence, and the sequence may be changed in the actual operation, for example, the fecal sewage may be first treated by biodegradation and then subjected to solid-liquid separation.
In the first step, the filtering device is a filter screen 3, and the first compartment 21 and the second compartment 22 are separated by the filter screen 3. The filter 3 filters the filth falling into the first compartment 21, so that only the liquid component of the filth can naturally enter the second compartment 22 through the filter 3, and the solid component is intercepted and stays in the first compartment 21; i.e. only liquid dirt is present in the second compartment 22; the sieve 3 here simultaneously serves to separate the first compartment 21 from the second compartment 22 and to filter solids.
The second compartment 22 is communicated with the first treatment box 4 through a drain pipe, and liquid sewage in the second compartment 22 is discharged into the treatment device for environmental protection treatment; that is, the eco-friendly toilet system environmentally treats only the liquid component of the toilet waste, and the solid component is collected in the first compartment 21.
Because people can flush after finishing using the toilet, most of the sewage generated by using the toilet is liquid components, the solid components only occupy a very small proportion, the toilet device only collects the solid components which occupy less amount in the sewage, and only needs to be manually cleaned once for a long time, particularly for the toilet arranged in a remote area, the use frequency is low, the time for carrying out two cleaning operations is possibly separated by years, and the workload of cleaning personnel is greatly reduced; meanwhile, compared with solid components, liquid components in the dirt are easier to treat, and the pollution to the outside is smaller. This environmental protection lavatory system carries out environmental protection through only carrying out environmental protection to the liquid composition in the filth and handles, on the basis of practicing thrift treatment cost, has greatly alleviateed the pollution to external environment, has made the balance between cost and environmental protection, is suitable for and uses widely, is particularly suitable for setting up in remote area, frequency of use is less, to the relatively sensitive small-size lavatory of cost.

In this embodiment, the second treatment tank 5 is subjected to biodegradation treatment by using an aerobic treatment process, and aerobic bacteria are put into the second treatment tank 5; the aerobic treatment process is a treatment method for degrading organic matters by carrying out biological metabolism by using aerobic bacteria in the presence of oxygen so as to make the organic matters stable and harmless; in the treatment process, microorganisms use organic pollutants in water as substrates to carry out aerobic metabolism, and after a series of biochemical reactions, the microorganisms release energy step by step and finally stabilize inorganic substances at low energy level to meet the requirement of harmlessness so as to return to the natural environment or further treat the inorganic substances; aerobic treatment is suitable as a further biodegradation treatment means on the basis of anaerobic fermentation treatment.
In addition, when the second treatment tank 5 is used for treatment, NaHCO is put into the second treatment tank 53Adjusting the pH value of the sewage to 7.5-8.0; when the pH value of the sewage is lower, the activity of aerobic flora can be inhibited, and NaHCO is added3 willWhen the pH value of the sewage is adjusted to 7.5-8.0, the biodegradation efficiency of aerobic treatment can be obviously improved.
In this embodiment, the third treatment tank 6 performs chemical treatment by adding hydrated lime; ca (OH)2As a flocculating agent, the phosphorus in the sewage can be removed, and the method is an economic chemical phosphorus removal means.
In this embodiment, the fourth treatment tank 7 is provided with an ozone generator 72 for generating ozone to sterilize and disinfect the sewage. In addition, the third overflow pipe 61 is filled with activated carbon, so that the chromaticity of the sewage can be removed, and the sewage becomes pure and transparent.
Through the treatment process, the fecal sewage can be treated in an all-round way, so that various indexes such as Chemical Oxygen Demand (COD), phosphorus content (TP), ammonia nitrogen content index (NH3-N) and the like in the fecal sewage are remarkably reduced in an all-round way, and the method is very suitable for treating the fecal sewage.
It should be noted that the embodiment of the present invention using four processing boxes for processing is only a preferred embodiment, and in practice, any number of processing boxes can be freely adopted to form the processing device, and these combinations are easily conceived on the basis of the present invention, and do not exceed the protection scope of the present invention.
