Problems solved by technology

However, since the current membrane technology is only applied on the ground, the choice of the form, structure, material and working method of the membrane will affect the dissolution of oxygen and the utilization of microorganisms.
Therefore, there is no mature technical reference on how to reasonably select the material and structure of the membrane, set up an appropriate working mode, and improve the utilization rate of oxygen under space microgravity conditions, and a large number of experiments in combination with practice are still needed

Abstract

The invention discloses an oxygen supply device and method for space wastewater treatment. The device is connected into a wastewater treatment liquid circulating loop in series; the oxygen supply device is mainly composed of an oxygen supply membrane assembly, a pressure sensor, a solenoid valve, a flow meter, a decompression valve and an oxygen storage bottle. A membrane wire in the oxygen supplymembrane assembly is made of a hydrophobic polyvinylidene fluoride (PVDF) material with high oxygen permeability; two ends of the membrane wire are encapsulated at two ends of the oxygen supply membrane assembly shell body through an epoxy resin bundle. Oxygen enters wastewater treatment liquid, which flows through a membrane pipe, through micro-pores formed in a membrane pipe wall from the outside of the membrane wire under proper pressure, and then is absorbed and utilized by a microorganism. An oxygen supply mode is determined through dissolved oxygen (DO) of the wastewater treatment liquid and gas pressure in the oxygen supply membrane assembly. The oxygen supply device and method disclosed by the invention are applicable to equipment for microorganism wastewater treatment and the like under future space conditions, and a novel technical means is also provided for carrying out basic researches of properties of the microorganism wastewater treatment and the like on the ground.

Description

technical field [0001] The invention belongs to the field of long-term manned spaceflight environmental control and life protection technology research, and in particular relates to an oxygen supply device and method for microbial treatment of wastewater under space microgravity conditions. Background technique [0002] Long-duration, long-distance and multi-crew space flight is the development trend of manned spaceflight in the future. Using biotechnology, simulating the principles of natural ecology, and establishing a bio-regenerating life support system outside the earth, so as to realize the continuous supply of on-site regeneration of crew life protection materials, is currently a research hotspot in various aerospace powers. In the biological regenerative life support system, microorganisms are the decomposers in the system, and their main function is to decompose various organic pollutants in the system (mainly in waste gas, waste water and waste) into other organism...
