Abstract
An ecological treatment system for waste water containing heavy metals comprises a biological absorption pool, an inclined plate precipitation pool, an ecological purification pond and an ecological treatment channel. The waste water containing the heavy metals flows into the biological absorption pool through a water inlet, most of heavy metal ions are removed by the absorption of biological absorbing agents, then the waste water enters into the inclined plate precipitation pool after being filtered by a grille, the biological absorbing agents precipitate on an inclined plate and slide down to the bottom of the precipitation pool to be discharged together. After the precipitation, water quality meets the waste water comprehensive discharge standard, and the waste water is discharged into the ecological purification pond and finally led into the ecological treatment channel. Heavy-metal-gathering type submerged plants including potamogeton crispus, potamogeton pectinatus, potamogeton malaianus and the like can further reduce content of the heavy metals, ammonia, nitrogen, phosphorus and organic matters in the waste water, and finally the waste water can meet the surface water environmental quality standard before entering into rivers and lakes. The ecological treatment system achieves the recycling of waste water treatment and regeneration and cyclic utilization of plant materials, and has good environmental benefits and economical benefits.
Description
Technical field
The utility model relates to sewage treatment area, relates in particular to a kind of ecological treatment system that based on waterplant the inrichment of heavy metal is shifted or removes heavy metal in the waste water.
Background technology
Along with the development of activities in production such as mining mineral resource, smelting, processing, mining area surface water generally is subjected to heavy metal contamination, jeopardizes peripheral resident's productive life, and environment hidden danger is heavy.The trade effluent that heavy metal pollution of water body mainly discharges from industries such as non-ferrous metal metallurgies.The whole scientific and technological level of China's mining industry industry at present is more backward, and the Pollution abatement ability is low, and enterprise technology renewal and renovation of equipment replacement speed is slow, and the cleaner production level is low.
Method such as the deposition of heavy metal ion, oxidation, reduction, extraction, exchange, infiltration, absorption and technology all have been applied to control and the improvement that water pollutes.Wherein absorption method is a kind of method that has gained public acceptance, and gac then is a kind of sorbent material the most commonly used, but cost is too big, is difficult to for a long time implement.Therefore seek rationally, the water pollution control method of cheap, efficient, safety, environmental protection become the focus that people pay close attention to.
Waterplant is no matter be that live or the dead heavy metal that can both adsorb and shift in the water body, especially the ecotypic plant of minority anti-pollution in mining area, accumulation ability to heavy metal is very strong, the phytoremediation that not only can be used for heavy metal-polluted water can also be gathered in its overground part and is processed into the biology absorption that biological adsorption agent is used for heavy metal industrial effluent.
The Herba Potamogetonis Pectinati, leaf of bamboo Herba potamogetonis distincti, the water caltrop that are distributed in the mining area all belong to the Potamogetonaceae submerged plant, have very strong anti-pollution ability.The Herba Potamogetonis Pectinati four seasons are evergreen, blade slice in winter shape, summer fine rule shape, the four seasons all can be grown anti-rapid current, well-grown in mobile water bodys such as river, irrigation canals and ditches; Leaf of bamboo Herba potamogetonis distincti is annual, but can survive the winter with subterraneous stem, spring germinating growth, winter apoptosis, the blade ribbon, wide more much bigger than Herba Potamogetonis Pectinati leaf; Water caltrop is perennial heavy this plant of pasture and water, is born in pond, lake, the streams, and hydrostatic pond or irrigation canals and ditches are more, and water body is little acid to neutral more.This three kind of plant all has very strong patience and accumulation ability to heavy metal, and is also fine to the assimilation effect of nitrogen, phosphorus.In the prior art, also do not adopt Herba Potamogetonis Pectinati, leaf of bamboo Herba potamogetonis distincti, water caltrop to be applied to the case of heavy metal containing wastewater treatment.
The utility model content
The utility model aims to provide and a kind ofly utilizes the mining area plant that the inrichment of heavy metal is purified the ecosystem of heavy metal-containing waste water, in order to realize a kind of rationally, cheap, efficient, safety, environmental protection the water pollution control method.
The technical solution of the utility model is a kind of ecological treatment system of heavy metal-containing waste water, comprises biological adsorption tank, inclined-plate clarifying basin, the ecological purification pool, four parts of Ecological Disposal canal.
