Description
Technical field
The utility model relates to a kind of biofilm reactor, mainly adopts the microbial film processing mode to carry out the processing of sewage.
Background technology
Water is the human lives, produce in requisite resource, along with economy in the global range and Increase of population, the demand of water is presented the trend that increases gradually.On the other hand, the pollution of water body and the atrophy at water source have produced the contradiction between water supply and the need water, and water has become the restraining factors of modern society and Economic development.
Municipal sewage as a resource is meant that municipal effluent and trade effluent reach certain water quality standard through suitably handling, and makes it to become the part of urban water resource, reaches the purpose that makes full use of water resources and alleviate ambient pollution burden.
China is as water big country and one of 13 poor-water states in the world, and under the limited prerequisite of gross amount of water resources, the new water resources of simple exploitation is not all right, and increasing income develops simultaneously with throttling is only the effective way that solves this difficult problem.
Biomembrance process is to utilize the microorganism (be microbial film) of apposition growth in some solids surface to carry out the method that organic sewage is handled.The ecosystem that microbial film is made up of aerobic bacteria, anerobe, amphimicrobe, fungi, protozoon and the algae etc. of highly dense, its solid dielectric that adheres to is called filtrate or carrier.Microorganism growth accumulative carrier (generally claiming filler) is set in sewage treatment structure, under the condition of oxygenation, microorganism is at the poly-formation microbial film that adheres to of filling surface, when the sewage of process oxygenation (oxygenate apparatus is made up of water treatment aeration blower fan and aerator) flows through filler with certain flow velocity, microorganism in the microbial film absorbs the organism in the water of decomposition, sewage is purified, and microorganism also obtains propagation simultaneously, and microbial film thickens thereupon.When microbial film rises to certain thickness, be restricted to the oxygen of microbial film internal divergence, its surface has been still oxygen condition, and internal layer then can be anoxic even anaerobic state, and finally causes biomembranous coming off.
Microorganism is along the general designation of the epontic bioremediation of solid (can claim carrier) in the waste water.Because of microbial population grows into the mucous membrane shape along solid surface, so name.When waste water contacted with microbial film, pollutent was transferred on the film from water, thereby obtained handling.
