Learned from the Nanjing Forestry University, the University Professor Huang Xin, and other experts, with the waste fly ash,bamboo furniture with Canna, dry the umbrella bamboo, water onion, iris and other plants to contaminated river water "purification."
The use of microorganisms with plant pollution research project "Urban Ecology in high-pollution water treatment and utilization technology" has successfully passed the Jiangsu Provincial Environmental Protection Department of the review and acceptance, and national patent applications.
Currently, the city of polluted water containing high organic matter, nitrogen and phosphorus and other nutrient concentrations higher. General direct method of repair in the water will flow and drip water features often affected, and artificial aquatic plants and animals and some carriers will be taken away by a flood, bamboo flooring causing loss of function and partial purification of economic losses.
Huang said that their research, another way to deal with biological and ecological combination of methods designed to plant a biological filter and filter bed, filter built-in spherical particles of fly ash waste as a useful filter, filter bed placed part of the spherical particles of fly ash and planted with Canna,bamboo kitchen dry the umbrella bamboo, water onion, iris and other aquatic plants. Fly ash in itself is not drugs, but with the filter made of spherical particles of fly ash and microbiological safety of the filter bed has given a warm "home" with such "home", a large number of micro-organisms before they can gather to big mouth , a large number to "eat" organic matter in water and ammonia, nitrogen and other pollutants. After such filtering sewage filter plants and then went to bed. Next, aquatic plants and microbial pollution of the river further, "detoxification." Huang said that the sewage plant, "detoxification" has unique and plant growth cycle, a cycle down, plant roots absorb toxins through the death of plants can be as thorough with the water body. After joint treatment plant and microbial sewage after, the nitrogen and phosphorus nutrients, particularly phosphorus removal significantly. Polluted river water into the device to the outlet, four to go through customs, every customs are different for different pollutants in effect, out of the water fully meet the standards of the reuse water can be used green, water spray and as a landscape supplementary water.
Such a treatment plant, process technology is not complicated, running cost is not high, the current testing equipment to reach back to the river water per ton of water pollution and emission requirements of the operating costs of water may be lower than the 0.35 and 0.25 yuan respectively, the scale of the cost will be running lower.
