Abstract

The invention provides a method for treating a desert by using municipal domestic sewage. The method is characterized by comprising the technological processes of collecting the municipal domestic sewage and conveying the municipal domestic sewage to an arid desertification region; screening, filtering and shunting to screen suspended matters and impurities with larger volumes; carrying out anaerobic digestion treatment on the screened, filtered and shunted suspended matters and impurities; sand-filtering and purifying the screened, filtered and shunted sewage; curing the purified pure water; and then conveying one part of the pure water to the desert, transformed farmlands or woodlands for irrigation via closed conduits, wherein the closed conduits are used as device for storage and further purification; and further purifying the other part of the pure water into domestic water. The method provided by the invention has the advantages that thirst deserts are treated by using the municipal domestic sewage to get vitality gain and the deserts are transformed to normal lands to be survival lands of human beings and all living beings. The two harm sources of the deserts and the domestic sewage in the world are transformed to green ecological systems benefiting humankind so that the ecological environment problem is effectively solved.

Description

technical field [0001] The invention relates to a method for treating deserts with urban domestic sewage, in particular to a method for utilizing urban domestic sewage to treat deserts. Background technique [0002] my country's ecological environment problems are quite serious. The tasks to be cured and dealt with effectively are arduous and complex, and there is a long way to go. [0003] Due to the shortage of water resources in our country and the serious imbalance in time and space distribution, rivers and lakes in natural waters are polluted and eutrophication problems are serious; the per capita arable land resources are limited, there are more people and less arable land, and climate changes are becoming more abnormal, natural droughts, floods, and food production The security foundation is very unstable, the forest coverage rate is seriously low; the limited arable land and natural pastures are seriously desertified and degraded, and there are practical problems su...
