Problems solved by technology

[0002] At present, the outstanding problems in water resources are: most of the effective fresh water resources on the earth are consumed by cities, and a large amount of sewage generated by cities is not purified and utilized, and is directly discharged into the ocean, causing increasingly serious marine pollution; Most areas, especially cities, are facing an increasingly severe crisis of fresh water shortages; the crisis of fresh water resources has led to the disappearance of a large number of surface fresh water surfaces, resulting in land desertification and the extinction and near-extinction of a large number of species that depend on wetlands for survival. The climate has deteriorated

Embodiment Construction

[0020] Below in conjunction with accompanying drawing and have this example to make further explanation:

[0021] Such as figure 1 and 2 As shown, the sustainable development type urban sewage purification utilization method of the present invention is that after the urban sewage is collected, the solid matter is initially reclaimed by filtration and sedimentation, and then the sewage is removed by the method of planting water hyacinth, rice grass and other aquatic plants that are conveniently harvested The nutrient-rich substances in the mangroves are finally purified by artificial swamps planted with mangrove-based aquatic plants, and the purified water flowing out of the artificial swamps circulates between the urban artificial river network, biological purification pools and artificial swamps . The aquatic plant products harvested by the biological purification pond are used to produce biogas, which is used to generate electricity and supply gas to cities, and the electr...

Abstract

The present invention provides one kind city sewage purifying and utilizing process and apparatus for sustained development. The city sewage purifying and utilizing process includes first filtering and precipitation to recover solid matter, planting aquatic plant to gather feed and for producing marsh gas, and purifying water in artificially marsh. The present invention can purify sewage and utilize nutrients in sewage fully to improve ecological environment around city.

Description

technical field [0001] The invention relates to the treatment technology of sewage and waste water, in particular to a sustainable development type urban sewage purification and utilization method and its device. Background technique [0002] At present, the outstanding problems in water resources are: most of the effective fresh water resources on the earth are consumed by cities, and a large amount of sewage generated by cities is not purified and utilized, and is directly discharged into the ocean, causing increasingly serious marine pollution; Most areas, especially cities, are facing an increasingly serious crisis of fresh water shortage; the crisis of fresh water resources has led to the disappearance of a large amount of surface fresh water, resulting in land desertification and the extinction and near extinction of a large number of species that depend on wetlands for survival, and also caused The climate has deteriorated and caused enormous damage to agriculture, ca...
