Composite ecological water purification system and water purification method thereof

Abstract

The invention discloses a composite ecological water purification system. The system comprises a water purification pool and a composite filler with which the water purification pool is filled, and the top of the composite filler is provided with water purification plants and a water inlet pipe; a water inlet end of the water inlet pipe is communicated with external to-be-purified sewage, and a water outlet end of the water inlet pipe is arranged on the surface of the composite filler; the system further comprises a drainage pipe and a vent pipe, a water inlet end of the drainage pipe is disposed at the bottom of the composite filler, and a water outlet end of the drainage pipe is communicated with the outside; an air inlet end of the vent pipe is communicated with outside air, and an airoutlet end of the vent pipe is disposed in the composite filler. The invention also discloses a water purification method of the composite ecological water purification system. An autonomous re-oxygenation process in the water purification system can be completed, and gas generated in the process of decomposing the sewage by microorganisms can also be discharged, so that the water purification system is unlikely to be blocked, the activity of the microorganisms is increased, and thus the water purification efficiency is improved. The water purification system also has the advantages of being flexible, practical, small in occupied floor, low in cost and energy consumption and easy to maintain.

Description

technical field [0001] The invention relates to the technical field of ecological water purification, in particular to a composite ecological water purification system and a water purification method thereof. Background technique [0002] At present, in most areas of our country, especially in villages and towns with a relatively backward economy, domestic sewage is generally discharged directly into rivers and lakes without treatment, which leads to eutrophication of water bodies and degrades water quality. At the same time, because the villages and towns in our country have the characteristics of wide distribution, scattered distribution, complex geographical and landform distribution, relatively backward economy, and large regional differences, it is not advisable to adopt a unified model to solve problems such as domestic sewage, black and odorous water bodies, and tail water. Operability is poor. The treatment of domestic sewage should be treated differently according ...

AI Technical Summary

Problems solved by technology

[0003] At present, in addition to the conventional traditional activated sludge process in village and township sewage treatment, technologies that are widely used include constructed wetland, rapid infiltration treatment system, purification tank technology, oxidation pond technology, etc. Among them, the application of constructed wetland and oxidation pond treatment processes is more common , the oxidation pond process is suitable for treating sewage with low pollution levels, but it has the problems of poor impact load resistance, large land occupation, and low treatment efficiency; although constructed wetlands have relatively small investment costs, low operating costs, and low technical requirements for operation and maintenance , can be combined with the characteristics of landscape construction, but also has the defects of large area, easy to block, low processing load, poor impact load resistance, and it is not easy to maintain and manage
