The biochemical combined reactor of the sewage disposal of above-mentioned structure can not established wall of container and directly place and in the pond sewage disposal is carried out as container in the pond, also can be provided with outside vessel, make to have above-mentioned structure in the container, entire sewage is handled biochemical combined reactor place the place that to carry out sewage disposal.
On the basis of the above-mentioned basic structure of the biochemical combined reactor of described sewage disposal, manually construct out a comprehensive ecological wastewater processing reactor of forming by biological (as: bacterium, algae, protozoon, metazoan, waterplant, high hydrocoles) and abiotic (illumination, wind, temperature, organic loading, pH value, dissolved oxygen, N and P nutritive element etc.).
The biochemical combination of described sewage disposal reacting appliance has pollution not shift, reduce discharging guaranteed, ecological all standing, the biological full essential characteristic of handling.Sewage has realized that in biochemical combined reactor sewage, mud, dirt handle fully, has thoroughly eliminated secondary pollution and pollution transportation that conventional Sewage Plant grid slag, dirty sand, mud, stink etc. cause.Specifically, have the following advantages.
1) there is not stink in the treating processes
The biochemical combined reactor bottom of sewage disposal is the anaerobic sludge digestion treatment zone.Gases such as the hydrogen sulfide that produces in the digestive process can only be by effluxing behind the aerobic zone.There is a large amount of dissolved oxygens therefore gas moment oxidations such as hydrogen sulfide thoroughly can have been eliminated the stink that produces in the sludge disposal in the aerobic zone.
2) seldom and inorganicization, stabilization of sludge yield, cleaning in general 10~25 years once.Avoided the secondary pollution and the transfer that produce in conventional sewage work disposing sludge dirt and the transportation.
3) the biochemical combined reactor construction period weak point of sewage disposal, low to the construction land requirement, required job facilities are few: level land, hillside fields all can be built; Hole, the pool, ditch are repaired and can be used; Because free from extraneous odour, no dirt produce, and can be used as water scenery and incorporate in the construction in Urban Parks, greenery patches; Can also on dispersive vacant lot, city, build.
The biochemical combined reactor of sewage disposal comprises the sludge treatment district, has saved the popular response device and must establish expensive sludge disposal equipment, structures in addition.
4) effluent quality is good, and is stable
Electromechanical equipment quantity is few, and the probability that produces fault is low.
5) running cost is low
The biochemical combined reactor of sewage disposal has merged self purification of water body and two functions of artificial aeration's intensive treatment, has integrated multinomial advanced reactor, need not handle mud, dirt for many years, and therefore, processing cost has only the 1/3----1/2 of popular response device.
6) reactor is succinct, operational administrative is simple, strong shock resistance.
7) flexible operation, processing power are adjustable in a big way.
8) perfect adaptation of realization sewage disposal and landscape construction makes peripheral land price increment;
Breaking the normal procedure, (air that is produced and mud pollute in sewage work, directly or indirectly reduce peripheral Land values) fixed pattern, the biochemical combined reactor of sewage disposal can build up ecological park, both can build ecoscape, improve the ecological environment, can be dissolved in the urban afforestation again, make peripheral land price increment.The shape of the biochemical combined reactor of sewage disposal can according to view require and topographical condition definite, can be rectangle, trapezoidal, circular, semicircle, Polygons, irregular polygon or other shapes, adopt a kind at least, its cross section can be for trapezoidal.
