Problems solved by technology

The treatment efficiency of most toilet sewage is very low, especially in rural villages and market towns in China, most of the toilet sewage is directly discharged into water bodies without any treatment, causing widespread pollution of rural rivers and seriously threatening groundwater, and even some Shallow groundwater has been polluted and cannot be used
[0003] The toilets, sewers and wastewater systems used in developed countries are land, energy and water intensive and expensive to build and maintain
Existing lower-cost alternatives either lack practicality, cannot eliminate odors and attract mosquitoes, and are often not accepted by users

Embodiment 1

[0030] The toilet wastewater first passes through the toilet bowl coated with a superhydrophobic coating film made of PE nanometer superhydrophobic interface material, and then 8 friction nanoelectric power generation using the polymer polydimethylsiloxane film coated with silver electrodes as the contact surface The motor drives the air flushing unit to flush the toilet wastewater into the drainage pipe, and the toilet wastewater is classified and collected and treated in the underground toilet treatment center.

[0031] The first-stage treatment is drying treatment, using 4-purpose grids to separate toilet paper and large particles to obtain the first type of solids, and then burn the collected first-type solids through a solar-powered compression water remover and biogas The heat produced is dried, and the volume of the solid after drying is compressed by 70%. Finally, the obtained solid is fired into biochar in a muffle furnace powered by solar energy in a biogas atmosphere...

Embodiment 2

[0037] The toilet wastewater first passes through the toilet pan coated with a super-hydrophobic coating film made of PTE nano-super-hydrophobic interface material, and uses five polymer polydimethylsiloxane films coated with silver electrodes as the contact surface to drive the frictional nano-generator. The air flushing unit flushes the toilet wastewater into the drainage pipe, and the toilet wastewater is classified and collected and treated in the third stage in the underground toilet treatment center.

[0038] The first-stage treatment is drying treatment, using a 50-mesh grid to separate toilet paper and large particles to obtain the first type of solids, and then burn the collected first-type solids through a solar-powered compression water remover and biogas The generated heat is dried, and the volume of the solid after drying is compressed by 80%. Finally, the obtained solid is burned into biochar in a muffle furnace powered by solar energy in a biogas atmosphere at 30...

Embodiment 3

[0044] The toilet wastewater first passes through the toilet bowl coated with a superhydrophobic coating film made of EVA nanometer superhydrophobic interface material, and uses three polymer polydimethylsiloxane films coated with gold electrodes as the contact surface to drive the frictional nanogenerator. The air flushing unit flushes the toilet wastewater into the drainage pipe, and the toilet wastewater is classified and collected and treated in the third stage in the underground toilet treatment center.

[0045] The first-stage treatment is drying treatment, using 150-mesh grids to separate toilet paper and large particles, which are called the first-class solids, and then the collected first-class solids are passed through a solar-powered compression dehydrator and biogas The heat produced by combustion is dried, and the volume of the solid after drying is compressed by 90%. Finally, the obtained solid is burned into biochar in a muffle furnace powered by solar energy in ...

Abstract

The invention discloses a toilet wastewater treatment process, belongs to the technical field of wastewater treatment. The process comprises the following steps: firstly, the toilet wastewater flows through a toilet closestool; then, a friction nano-generator drives an air impact unit to flush the toilet wastewater into a drainage pipeline; and finally, an underground toilet treatment center is used for treating wastewater. With the principles of energy conservation and emission reduction, the process is used for treating pollutants discharged from a toilet, recycling energies and resources, and realizing the establishment of a toilet treatment center for harmless and pollutant-free fecal emission and material recycling and without external water pipes, sewers or power supply networks in densely populated urban communities.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a toilet wastewater treatment process. Background technique [0002] Water is the source of human life and the foundation of survival. With the development of industrial and agricultural production, water environment problems have become more and more serious. Water quality problems have seriously affected our normal life, and the problem of sewage treatment from toilets has gradually attracted attention. The treatment efficiency of most toilet sewage is very low, especially in rural villages and market towns in China, most of the toilet sewage is directly discharged into water bodies without any treatment, causing widespread pollution of rural rivers and seriously threatening groundwater, and even some Shallow groundwater has been polluted and cannot be tapped. [0003] Toilets, sewers and wastewater treatment systems used in developed countries are la...
