Rainwater wash-out ecological toilet based on solar power generation and sewage treatment method thereof

Abstract

The invention discloses a rainwater wash-out ecological toilet based on solar power generation. The rainwater wash-out ecological toilet based on solar power generation comprises a rainwater filtering and collecting system, a solar power generation and supply system, a PLC control system, an integrated public toilet body, a combined sewage treatment system and a composite artificial wetland system which are all sequentially connected. The solar power generation and supply system is arranged on the top of the integrated public toilet body and used for supplying power to the rainwater filtering and collecting system, the PLC control system, the integrated public toilet body, the combined sewage treatment system and the composite artificial wetland system. The rainwater filtering and collecting system is used for collecting rainwater and filtering and processing the rainwater, and then the rainwater can be supplied to the toilet. The combined sewage treatment system and the composite artificial wetland system are connected in series for use and used for processing drained water of the toilet. The PLC control system is used for performing automatic control over the whole system. The toilet supplies power through clean energy. The drained water of the toilet can be effectively processed, maintenance cost is low, and the ecological toilet has very important ecological benefits, economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a rainwater flushing ecological public toilet based on solar power generation. Background technique [0002] In recent years, with the change of people's concept of tourism and consumption, more and more people pay more attention to ecological tourism close to nature, which eventually leads to a significant increase in the flow of people in these relatively primitive natural scenic spots than usual, and a large increase in the number of people entering and leaving public toilets , the water consumption and electricity consumption of public toilets also increased. Present public restrooms generally utilize the water supply of the municipal water supply system to wash hands and flush the toilet, and utilize the mains power supply system to maintain the operation of the energy-consuming equipment of the entire public restroom. However, in some tourist attractions, especially remote ...

AI Technical Summary

Problems solved by technology

However, in some tourist attractions, especially the relatively remote primitive natural scenic spots and scattered natural attractions, these public supporting facilities are far away from the municipal water supply and power supply network.

Therefore, for the public toilets set in natural attractions, it is more difficult to supply water through the municipal water supply system and the power supply system. There is no water to wash hands after going to the toilet, and there is no water to flush the toilet in the toilet in time. There are no ventilation and exhaust facilities on the floor, which not only affects personal hygiene, but also makes it difficult to see and smell bad in the entire public toilet, resulting in a lower evaluation of tourist attractions by toilet users

In addition, even if the water supply and power supply pipe network is connected to the scenic spot, due to the increase in the flow of people, the water consumption of public toilets will increase, resulting in an increase in water costs and sewage discharges in public toilets, which will increase the load on the sewage pipe network and sewage treatment plants.

At present, some methods use sewage flushing, packaging and recycling, and the operation and management costs are relatively high. Some also use in-situ landfill degradation methods, which cannot effectively remove pathogens such as E. coli, and cause serious environmental pollution.

[0003] For example, the utility model patent with application number CN200920230651.4 discloses a box-type ecological toilet, but the toilet is only equipped with a simple box-type structure, which cannot be used for sewage treatment and is likely to cause harm to the environment

And the application number is CN200410026169.0 a kind of intelligent environment-friendly ecological toilet, although it has waste water treatment device, its treatment equipment adopts devices such as activated carbon column, ozone sterilizer, its construction cost is higher, and its maintenance cost is also that public facilities cannot afford of
