Full-automatic water ecology improvement device based on plant technology

Abstract

The invention discloses a full-automatic water ecology improvement device based on a plant technology. The full-automatic water ecology improvement device comprises a methane tank, a storage battery pack and a methane generator, wherein the methane tank comprises a feed inlet and a gas outlet; the gas outlet of the methane tank is connected with the methane generator through gas supply; the methane generator is connected with the storage battery pack through power supply; the full-automatic water ecology improvement device based on the plant technology further comprises a stable breeding cage,a watercourse blockage prevention mechanism and an automatic collection mechanism. The number of plants in the stable breeding cage can be scientifically and effectively controlled, and surplus plants can be periodically sent into the methane tank. The generated electricity is supplied to the storage battery pack for electric energy storage for other purposes, thereby forming environmental protection utilization of the surplus plants, and residues in the methane tank can be used as fertilizer, feed and the like. The arrangement of the full-automatic water ecology improvement device provided by the invention not only treats sewage, but also realizes beneficial improvement of watercourse water ecology, and saves a lot of manpower and material resources through highly automatic arrangement.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a fully automatic water ecology improvement device based on plant technology. Background technique [0002] In recent years, with the construction of water ecological civilization and the strengthening of lake and river management, the concept that green water and lush mountains are invaluable assets has become more and more popular. How to treat sewage scientifically, effectively, environmentally friendly and sustainably has become a technical difficulty. [0003] With the continuous development of urbanization and the rapid expansion of cities, new small towns continue to emerge, which brings great difficulties to municipal sewage treatment. [0004] Due to the large population and concentrated living in my country, the pressure on the environment is high, which makes the environmental capacity of the aquatic ecosystem small and sensitive to the input of nutrients such as N and P. ...

AI Technical Summary

Problems solved by technology

A major reason for limiting the popularization of this technology is that this technology mainly relies on wetland plants and soil microorganisms to purify nitrogen in sewage, and remove phosphorus through plant absorption and precipitation. These processes depend on local climate conditions; in addition, for surface Flow-type constructed wetlands are prone to breed mosquitoes and flies; while subsurface-flow constructed wetlands are prone to blockage

my country has also carried out a lot of research on artificial wetlands, and established some exemplary artificial wetland systems, and has conducted research on floating bed technology - a kind of floating material to carry plants, so that plants float on the surface of sewage water, and use the absorption and roots of plants Surface microbial purification technology of sewage - a lot of research has been carried out, and the above problems have been overcome to a certain extent. However, there are still few reports on how to overcome the limitations of climatic conditions and improve the purification efficiency of wetland systems

Among them, ryegrass is mainly used widely. However, even if there is no problem of excessive pollutants in the supply market of hydroponic agricultural products that use municipal sewage as a nutrient source, it is often difficult for consumers to accept it psychologically. This approach has not really been adopted. Pass

The lack of growth of terrestrial plants relative to aquatic plants also makes terrestrial plants inferior to aquatic plants in terms of treatment efficiency

Wetland plants, especially plants such as water hyacinth and water lily, have low requirements for nutrient concentration and grow rapidly. They are ideal plants for absorbing and removing nutrients. Flow into the environment and be avoided by people intentionally

[0006] It can be seen that using plant characteristics to treat sewage is a simple and easy method with low cost, energy saving and high efficiency. However, due to the rapid growth of plants and flooding, it takes a lot of human resources to salvage and treat the excess plants. , leading to overcorrection
