The invention provides a harmless treatment method for feces of a travel public toilet, which comprises the following steps:
step 1: separate excrement and urine through above-mentioned excrement and urine preprocessing device, at first be used for supplying the user to input excrement and urine into the discrete bin 1 through feeder hopper 2, excrement and urine gets into the discrete bin 1 back, 3 on dropping the filtration conveyer belt, the urine flows the bottom of discrete bin 1 through the micropore, then flow in liquid discharging pipe 6 along the diapire of slope, all the other excrement and urine convey 4 departments to the solid discharge mouth along filtering conveyer belt 3, excrement and urine drops to the play flitch 5 of slope from solid discharge mouth 4, and flow out, then the user collects the solid excrement and urine after the preliminary treatment on going out flitch 5. Urine flows into the filter bin 7 through the liquid discharge pipe 6, then is filtered through the first filter membrane 8 and the second filter membrane 9 made of ceramic membranes, and is adsorbed through the activated carbon 10 between the first filter membrane 8 and the second filter membrane 9, and the filtered urine flows out through the liquid discharge pipe 11.
Step 2: and (2) carrying out microbial treatment on the urine obtained in the step (1) to decompose urea and eliminate peculiar smell, wherein the microbes comprise one or more of nitrobacteria, nitrosobacteria, denitrifying bacteria and bacillus.
The polyurethane foam is used as a biological carrier, has good mechanical strength, is favorable for immobilizing microorganisms such as nitrobacteria, nitrosobacteria, denitrifying bacteria and bacillus, and can efficiently decompose substances such as urea in urine.
And step 3: and (3) sterilizing the urine obtained in the step (2), and sterilizing the urine by adopting an ultraviolet lamp, wherein the ultraviolet lamp is an UV ultraviolet lamp. The ultraviolet lamp is put into the sleeve made of transparent material and then immersed in urine to kill bacteria including bacteria propagules, spores, mycobacteria, coronavirus, fungi, rickettsia, chlamydia and the like.
And 4, step 4: and (3) crushing the excrement obtained in the step (1), then dehydrating, and dehydrating the excrement by adopting a centrifugal machine.
And 5: fermenting the solid excrement obtained in the step (4), mixing anaerobic bacteria and spraying a proper amount of liquid obtained in the step (2) into the solid excrement, placing the solid excrement into a plastic greenhouse, fermenting by utilizing solar energy, treating the liquid generated in the step (4) through the step (2), wherein the anaerobic bacteria comprise bacillus licheniformis and saccharomycetes,
the bacillus licheniformis decomposes toxic and harmful substances in urine and purifies water. And the bacillus licheniformis has stronger activity of protease, lipase and amylase and can degrade nutrients.
Yeasts grow in both aerobic and anaerobic environments, i.e., they are facultative anaerobes, which break down sugars into carbon dioxide and water under aerobic conditions and grow faster. In the absence of oxygen, yeast break down sugars into alcohol and carbon dioxide.
In summary, the method for harmless treatment of the public toilet feces for travel comprises the steps of firstly separating the feces from urine through the feces pretreatment device, then carrying out microbial treatment on the obtained urine to decompose urea and eliminate peculiar smell, wherein anaerobic bacteria comprise bacillus licheniformis and saccharomycetes, carrying out sterilization treatment on the urine obtained after the microbial treatment, putting an ultraviolet lamp into a sleeve made of transparent material, then immersing the sleeve in the urine to carry out sterilization treatment on the urine, killing bacteria comprising bacterial propagules, spores, mycobacteria, coronaviruses, fungi, rickettsiae, chlamydia and the like, crushing the solid feces obtained after the pretreatment, then carrying out dehydration treatment, and carrying out dehydration treatment on the feces by adopting a centrifugal machine.
