The invention relates to a compound artificial wetland treatment process of domestic sewage in villages and towns in rural areas. The process utilizes an artificial wetland treatment technology to be matched with a trough type automatically-flowing aeration channel for treating domestic sewage in rural areas. The treated sewage according with the standard can be drained in a local water environment and recycled as agricultural irrigation or environmental water. Compared with the conventional sewage in rural areas, the process adopts a benign artificial wetland ecological system with a certainecological landscape value; if not used, the artificial wetland can be used for secondary tillage to plant crops or fruit tress, thereby obtaining better ecological environment benefit. The technology has greater popularization and application values in rural areas.

The invention discloses a restoring method for a plateau reservoir hydro fluctuation belt through Knotgrass. Indoor and outdoor flooding simulation experiments for the Knotgrass are conducted to detect adaptability of the Knotgrass to the hydro fluctuation belt flooding environment; the Knotgrass is determined to still live after long time flooding; then the Knotgrass is introduced to the plateau reservoir hydro fluctuation belt; and after successful introduction, daily fertilizer and water management is conducted to the Knotgrass. The Knotgrass suitable for the plateau reservoir hydro fluctuation belt is found via systematical research; the Knotgrass is suitable for long term flooding of the plateau reservoir and can grow in the living environment exposed to the outside after flooding; certain biomass is achieved; certain landscape value is realized; and a certain protection action is conducted to water and soil loss of the plateau reservoir hydro fluctuation belt. By the use of the cultivation method for the Knotgrass in the plateau reservoir hydro fluctuation belt, the Knotgrass possesses high transplantation survival rate; and the Knotgrass can healthily grow with high efficiency on the hydro fluctuation belt.

The invention discloses an application of a Hawaii bamboo in processing waste water generated in raising livestockbelonging to the field of waste water processing. The technical proposal is that the Hawaii bamboo is planted in a polluted environment with waste water generated in raising livestock. In the invention, cold resistance of the Hawaii bamboo and adsorption removal property of pollutes in the waste water are made full use of and the Hawaii bamboo is planted in such a polluted environment to absorb pollutes in the accumulated waste water to lower content of pollutes in the waste water and purify the waste water generated in raising the livestock; the application has the advantages of low operation costs, good effect and simpleness and practicability in terms of operation, thus ensuring water purification effect while developing a new plant resource for processing of the waste water generated in raising livestock, bringing about new space new progress and development for in-depth development of human-made wet land for processing waste water generated in raising livestock; the Hawaii bamboo enjoys obvious advantages compared with the existing water purifying plants in terms of operation costs, operation maintenance, processing effect or landscape value.

The invention discloses a multidimensional ecological drainage system for intercepting and controlling separate system rainwater pollutants into a river. The system is arranged on one side of a river bank and takes a stair-step shape along the river bank; rainwater in pipe networks flows into a first-stage water drop platform by rain-water pipes, enters a storage pond, flows into an ecological buffer zone by a second-stage water drop platform, and lastly flows into a plant growth detention pond; and the first-stage water drop platform and the ecological buffer zone are slope-shaped, and plants are planted in the plant growth detention pond. The system not only ensures drainage, but also reduces the risk that rainwater polluted run-offs directly flow into the river, reduces impact and damage to water quality of the water body in a river channel, effectively controls the pollutants in the river, effectively improves the water environment, and enhances the urban water landscape value.
