Problems solved by technology
[0002] At present, most of the collection and transportation of household garbage still adopt a mixed method, which is not conducive to the treatment of garbage and the recycling of resources. Some developed countries have actively implemented the mode of classified collection and transportation.
The final disposal of domestic waste mainly includes sanitary landfill, high-temperature composting, and incineration. These processing methods have disadvantages such as low utilization rate of resources, secondary pollution to the environment, and high processing costs.
At present, urban domestic wastewater is composed of fecal sewage mixed with other domestic wastewater. Before the fecal sewage is properly treated, it is allowed to diffuse and pollute other domestic wastewater, which is not conducive to the treatment and reuse of wastewater and the conservation of water resources.

Embodiment Construction
[0013] Set up clear and turbid drainage pipes in the place where domestic wastewater is produced, and build biogas pools instead of septic tanks. The pool capacity is 1-3m for residential buildings 3 / household, office building 0.1~0.3m 3 / person, restaurant 0.02~0.1m 3 / guest, public toilet 1 ~ 5m 3 / Toilet position, the turbid drainage pipe leads from the toilet to the biogas digester; the garbage shredder can be configured for each household or for the public, or both.
[0014] Separation of clear and turbid waste water is implemented in the place where domestic waste water is generated, and dilute domestic waste water such as bath water, wash water, laundry water, and kitchen wash water is discharged through clear drains, and reused or discharged after purification.
[0015] At the place where domestic waste is generated, the waste is divided into perishable organic waste, recyclable waste, refractory organic matter, and things that have no recycling value. After the p...

A process for reclaiming the life garbage and sewage in urban area features that the life garbage is classified into the easily eroding organic waste, recoverable waste, the organic substance difficult to degradate, invalid substance, excrement-urine sewage, and washing sewage, and the reclaimable waste or sewage is used to ferment for generating marsh gas and the usable dregs.
Description
(1) Technical field [0001] The invention relates to a resource treatment method for urban domestic garbage and domestic wastewater. (2) Background of the invention [0002] At present, most of the collection and transportation of household garbage still adopt a mixed method, which is not conducive to the treatment of garbage and the recycling of resources. Some developed countries have actively implemented the mode of classified collection and transportation. The final disposal of domestic waste mainly includes sanitary landfill, high-temperature composting, and incineration. These processing methods have disadvantages such as low resource utilization rate, secondary pollution to the environment, and high processing costs. At present, urban domestic wastewater is composed of fecal sewage mixed with other domestic wastewater. Before the fecal sewage is properly treated, it is allowed to spread and pollute other domestic wastewater, which is not good for the treatment and reus...
