Processing method of ecological sewage

Abstract

The invention discloses a processing method of ecological sewage, which utilizes superior culture or biological activator as a core, assists growing herbaceous plant, builds an ecological dam and an ecological floating island, is combined with oxygenation algae restraining aeration technology in assisting mode to treat ecological sewage. The processing method of ecological sewage has the advantages of being capable of promoting pollutant substance degradation, transferring and transformation in multiple layers, reducing BOD and COD and purifying water, good in treatment effect, low in construction cost, free of energy consumption or low energy consumption, low in operation cost and the like. Simultaneously, no drug is cast to a water body, so that no secondary pollution is caused. The processing method is combined with afforest environment and landscape improvement to create graceful environment where people are melted with nature. The cheap practical technology is suitable for modification of ecological environment of water bodies including rivers and lakes and purification of micropollution water bodies like landscape water bodies in our country.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a treatment method for ecological sewage. Background technique [0002] According to incomplete statistics, the world discharges more than 430 billion tons of sewage every year, causing 5.5 trillion m 3 of water bodies are polluted, accounting for more than 14% of the total global runoff. Due to human activities, 1.4 million tons of nitrogen have been input into the environment, which is equivalent to 10 million trucks of nitrogen fertilizer every year. According to the survey and statistics of the United Nations, about 40% of the stable flow of rivers in the world is polluted; the World Health Organization also pointed out that nearly 80% of the world's diseases are caused by water pollution and basic sanitation equipment, and the world dies of waterborne diseases every day The number reached 25,000, and millions were physically damaged. At present, according to relevant data,...

Problems solved by technology

[0006] The ecological-biological water body restoration method uses the life activities of cultivated plants or cultured and inoculated microorganisms to transfer, transform and degrade pollutants in water, but these pollutants are largely deposited in the bottom mud of the water body. Once the pH of the water body And other indicators change, the pollutants will be re-dissolved in the water body, and the plants used are relatively simple, which cannot completely remove various pollution factors in the water body
