Embodiment 1

[0051] The integrated ecological toilet and manure treatment system was put in a rural area for a real-life test: first, the user presses the start button after going to the toilet to flush the feces with the driving force of negative pressure drainage, and records the number of times of toilet flushing. When the number of times of flushing the toilet is 150 times, it shows that the flow of people has reached 150 people, and the excrement has been collected in the storage tank 8, and the obtained excrement is a mixed material with a uniform concentration of 12.5%; then the screw pump 9 is used to pump the excrement to the hydraulic feed unit 10, and then pumped into the reactor unit 11 through the hydraulic feed unit 10, the feed flow rate is 50ml / min, and the reaction parameters are set by the monitoring unit 13. The pressure is 9.0MPa and the temperature is 300°C. Continuous hydrothermal treatment system After reaching a steady state, the hydraulic feed unit 10 has been conve...

Embodiment 2

[0053] The test of the back-end continuous hydrothermal treatment module of the integrated system was carried out with a mixture of human feces and corn stalks at a concentration of 15% as raw material: First, the corn stalks were mechanically crushed through 40-mesh human manure with a moisture content of 85%. Mix according to a certain ratio to obtain a mixed material with a concentration of 15%, use the screw pump 9 to pump the excrement to the hydraulic feed unit 10, and then pump it to the reactor unit 11 through the hydraulic feed unit 10, and the feed flow rate is 40ml / min, use the monitoring unit 13 to set the reaction parameters pressure 8.5MPa and temperature 290 ° C, after the continuous hydrothermal treatment system reaches a steady state, the hydraulic feeding unit 10 has been transporting materials, the reaction continues, the running time is 12 hours, and finally use the product to separate Unit 12 collects gas and liquid mixture, the gas is mainly CO 2 , the l...

Embodiment 3

[0055] The test of the integrated treatment system is carried out with simulated feces with a concentration of 20% as the raw material: firstly, 200g of the prepared simulated feces is used for toilet simulation, and after using the toilet, press the start button to flush the simulated feces with the driving force of negative pressure drainage , carry out 120 toilet simulations a day to characterize the flow scale of 120 people in the toilet; then use the storage tank 8 to collect the simulated ight soil, the obtained ight soil is a uniform concentration of 14% mixed material, and then use the screw pump 9 to pump the material sent to the hydraulic feed unit 10, and then pumped to the reactor unit 11 through the hydraulic feed unit 10, the feed flow rate is 45ml / min, and the monitoring unit 13 is used to set the reaction parameters. The pressure is 9.0MPa and the temperature is 300°C. After reaching a steady state, the hydraulic feed unit 10 has been conveying materials, the re...

Abstract

The invention belongs to the technical field of environmental protection and new energy, and particularly relates to an ecological toilet and excrement treatment integrated system, which comprises a front-end toilet module and a rear-end continuous hydrothermal treatment module, wherein the front-end toilet module and the rear-end continuous hydrothermal treatment module are respectively integrated in a vehicle-mounted container, the front-end toilet module comprises a yellow water lifting tank, a yellow water collecting tank, an air flushing urinal, an air flushing toilet pan, a brown water collecting tank, a brown water lifting tank, a vacuum lifting pump and a material storage tank, the rear-end continuous hydrothermal treatment module comprises a screw rod pump, a hydraulic feeding unit, a reactor unit and a product separation unit, the screw rod pump, the hydraulic feeding unit, the reactor unit and the product separation unit are sequentially connected through a pipeline, the material outlet of the material storage tank is connected to the screw rod pump, collected excrement is conveyed to the hydraulic feeding unit, enters the reactor unit, and is subjected to continuous hydrothermal treatment, and an oil phase, gas and solid residue are obtained through the product separation unit. The system of the invention has characteristics of mobility, water saving, energy self-supply and the like, and achieves the resource utilization of toilet excrement.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and new energy, and in particular relates to an integrated system of ecological toilet and excrement treatment. Background technique [0002] my country has a large population, and the amount of manure is increasing, and with the large-scale operation of agricultural production, the agricultural efficiency of manure is gradually reduced; due to the increasing requirements for environmental epidemic prevention, manure cannot be directly fertilized without treatment. At the same time, flushing toilets, which once played an important role in improving the living environment of human beings, has become a major source of waste and pollution of water resources, which does not conform to the current scientific development concept. [0003] Ecological toilets are characterized by reducing water consumption, that waste can be transformed into useful resources, that they do not pollute the ...
