Description
Technical field
The invention belongs to water body treating equipment and method and technology field, be particularly related to one and utilize microorganism in situ to excite
Quickly process the device and method of black and odorous water.
Background technology
Along with the continuous high speed development of urban economy, urbanization and process of industrialization are constantly accelerated, many industrial wastewater, rural areas
Sanitary sewage directly or discharge beyond standards, causes the severe contamination of lake and river water body.Micropollutant water refers to containing a small amount of
Organic pollution causes the water bodys such as higher river, lake and the reservoir of COD in water body, ammonia nitrogen and total phosphorus equal size.Although
This type of water body pollutes lighter relatively, it is impossible to manifests and causes serious harm in the short time, but micro-pollution of water body also exists potential
Cumulative bad harm.Most of micro-polluted river eco-environmental qualities are poor, it is impossible to meet water environmental function requirement.Lake, water
Storehouse and subsoil water are the important sources of China's freshwater resources, are also the main sources of Drinking Water in China, and long-term drink is contaminated
Water body, can cause damage to body.Meanwhile, nutritious in micro-polluted water body, it is also possible to bring the richnesses such as rivers and lakes
Nutrient laden phenomenon.
Chemical remediation technology, peripheral doses technology and biological-ecological is had to repair currently for micropollutant water treatment technology
Recovering technology.Chemical remediation technology is mainly by flocculation and precipitates and redox principle, adds chemical drugs in sewage
Agent or adsorbent, improve the indices of water body.This method easily causes secondary pollution, can destroy whole river ecosystem
Balance, meanwhile capital cost is big, but simple and fast compared with other restorative procedures, is generally used to emergent place
Reason.Peripheral doses technology carries out mechanical decontamination mainly by some engineerings to sewage, including diversion dilution, manually
The measures such as aeration, section dirt, bed mud desilting.Peripheral doses method can be arranged in pairs or groups use sometimes, it is also possible to is used alone, but because of
The balance of water ecosystem cannot be repaired during repairing water body, so effect is the best, before being typically used as it
Treatment measures are more.Bio-ecological restoration technology includes that oxidation pond technology, biologic product technology, artificial swamp and ecology are floating
Bed technique etc..Bio-ecological restoration technology can repair the balance of ecosystem, and operating cost while repairing water body
