What is the role of water purificion plants
By blocking effect of aquatic plants contaminants, microbial film formed on the organic aquatic plants Roots of the plant itself and degradation of absorption of nutrients and removal of contaminants. However, water purification plants What is the role?
The system decontaminating polluted lake or river water is introduced into the existing wetland pond or pond to create wetlands, the effect of aquatic plants by blocking contaminants, is aquatic root formation microbial degradation of organic matter film, and the plant itself absorption of nutrients and removal of contaminants. So water purification plants have what effect? Here, together with the small series to look at it.
As a good shielding effect of emergent plants with growth, can effectively inhibit the proliferation of algae, purified water back rearrangement lake or river.
water purification plant species have common bulrush, reeds, cattails, rushes, irises, sedges, Jing triangular, wild rice grass, water, peanuts and Tanabe grass. Most small amount kind reeds, cattails, etc., all over the choice of a certain degree of wetland plants dependent on the use of our experience, systematic research on a variety of plants used in sewage treatment effect is more scarce.
1. Eichhornia crassipes, known as water hyacinth, water lettuce and the like. Water hyacinth breeding fast, stain resistance, chemical oxygen demand (COD) in water, biochemical oxygen demand (BOD) has a significant effect of degradation, there is a certain effect on the absorption of nitrogen, phosphorus, potassium, and heavy metal ions, is a purification of sewage, landscaping ideal aquatic environment. Under suitable conditions, one hectare of water hyacinth 800 capable nitrogen emissions, phosphorus absorbed day. Water hyacinth can absorb heavy metal elements cadmium, lead, mercury, thallium, silver, cobalt, and strontium from sewage, water can phenol, cyanide and other toxic substances is decomposed into non-toxic substances.
2. Duckweed, Lemna minor also known. Duckweed can absorb a lot, the accumulation of heavy metal elements in the coal washing plant wastewater can effectively absorb, accumulation of waste decomposition nutrient salts and various organic pollutants.
remind you: because the minerals in the water will be involved in the bodys electrolyte balance, no water minerals likely to cause loss of nutrients in the body, and is not conducive to the absorption and metabolism of the human body needs a variety of nutrients.
