Embodiment Construction

[0007] The embodiment of the present invention is to the method for water recovery treatment on spacecraft: its equipment mainly contains ozone treatment device (with ozone generator and gas-water mixer), chemical treatment device (can add chemical reagent automatically), multi-layer graded filtration device, heating distillation device and cold air (cool mist) cooling device. When the domestic wastewater used by the astronauts immediately enters the ozone treatment device and fully mixes with ozone gas, then automatically adds chemical reagents to hinder the growth of microorganisms in the domestic wastewater, prevent chemical reactions such as corruption and deterioration, and achieve the purpose of deodorization and disinfection . The liquid is then filtered through a multi-layer filtration device to remove lumps and particulate matter. The filtrate enters the heating distillation device, and heating methods such as electromagnetic waves, microwaves, light waves or infrare...

Abstract

The invention provides a method for recovering and treating water in spacecrafts. In the spacecrafts, sanitary wastewater used by astronauts is first treated through an ozone / chemical treatment device, so as to be deodorized and disinfected; then the sanitary wastewater is subjected to multi-layer and classified filtration via a filtering device; filtrate enters a heating-distilling device; heated-distilled steam is directly combined with cold gas or cold mist in a cooling device so as to become water drops rapidly; and the water drops are collected and turned into pure distilled water. As the wastewater can meet the requirement of living water after purification, the method achieves the aims of recovering and recycling the sanitary wastewater in the spacecrafts. Precipitates left after filtration and distillation are used as garbage and treated separately.

Description

technical field [0001] The invention relates to a method for recycling and treating astronauts' domestic waste water on a spacecraft. Background technique [0002] On a spacecraft, astronauts cannot survive without water. However, the cost of carrying astronauts' domestic water is extremely expensive. It has been reported that the average cost per liter of water on a spacecraft is $11,000. The average daily domestic water consumption of each astronaut is about 4.5 liters, and the water price is as high as 50,000 US dollars. According to the searched information, the "urine cycle machine" invented by NASA Space Flight Center engineer Renee Carter is planned to be sent to the International Space Station next year to solve the problem of water recycling on the spacecraft. With the development of my country's aerospace technology, how to solve the recycling and recycling of wastewater on spacecraft is an extremely important engineering technology. In order to achieve the rec...
