Abstract
The invention discloses a built-in membrane symbiosis reactor, relating to a phycomycete reinforcement symbiosis reactor and a membrane filtration system. The membrane symbiosis reactor for domestic sewage and industrial waste water treatment comprises an annular reactor, a guide wall, a submerged propeller, and a built-in membrane filtration system. The reinforcement symbiosis system comprises algae and bacteria in the reactor and has no need of extra oxygen supply.
Description
Technical field
Built-in film symbiosis reaction unit relates to a kind of phycomycete and strengthens the symbiosis reaction unit.The built-in film symbiosis reactor assembly that specifically is used for sewage and Industrial Wastewater Treatment belongs to water-treatment technology field.
Background technology
Aerobic biological process for treating is an important step indispensable in present municipal sewage treatment and the Industrial Wastewater Treatment.In aerobic biological process for treating, need provide competent oxygen to supply mikrobe to carry out metabolism, thereby reach the purpose of handling pollutent.The oxygen supply mode generally adopts mechanical system aerations such as gas blower aeration or surface aerating machine at present; Consume a large amount of electric energy; The municipal sewage plant handles sewage per ton and consumes the 0.15-0.45 degree approximately; And gas blower aeration ubiquity noise is big, and surface aerating machine ubiquity efficient is low, the shortcoming of envrionment conditions difference.
Algae is synthesized organism with carbonic acid gas as carbon source, and discharges oxygen as a kind of photosynthetic organism under suitable illumination and sufficient nutrient thing condition.And the oxygen that the bacterium algae capable of using in the aerobe processing discharges carries out the oxygenolysis of pollutent, produces carbonic acid gas and supplies algae as carbon source, thereby make up cogeneration system with algae.
But this kind algae-bacteria symbiotic system is confined to the biological pond form basically at present, and there is following shortcoming in biological pond:
1, algae-bacteria symbiotic system is unstable in the pool, and living weight is few, and is low to the removal efficient of pollutent;
2, the depth of water is shallow, and hydraulic detention time is long, and floor space is excessive;
3, algae free settling not contains a large amount of suspended substances in the water outlet, and water quality is relatively poor.
Summary of the invention
The objective of the invention is to disclose a kind of built-in film symbiosis reaction unit that is used for sewage and Industrial Wastewater Treatment; This device available depth is more shallow; Utilize the nature sunshine, realize the growth of algae in reactor drum, produce oxygen through algae photosynthesis; And then the growth of realization aerobic bacteria in reaction unit; Form algae-bacteria symbiotic system, reach the purpose of pollution substances such as organism, nitrogen and phosphorus in the efficient removal water, and realize that simultaneously algae bio oxygen supply mode substitutes highly energy-consuming oxygen supply mode such as gas blower aeration or mechanical aeration in the existing sewage disposal technology; This device utilizes built-in membrane filtration system that water outlet is filtered simultaneously, makes to be difficult for settled algae and to be trapped in the reaction unit, guarantees to have competent phycomycete living weight in the reaction unit, and significantly improves effluent quality.This device has that processing efficiency height, energy consumption are low, noiselessness, stable advantage.
For reaching above-mentioned purpose, the present invention realizes through following technical scheme:
Built-in film symbiosis reaction unit at first is an annular reactor; For making algae growth and breeding in reactor drum, confirm the available depth and the useful volume of reactor drum according to influent quality and weather condition, wherein available depth is no more than 2 meters.For keeping the good mixing reaction conditions, the diving impeller is set in the reactor drum, mixed solution is flowed around training wall, flow velocity is not more than 1 meter per second.When phycomycete is cultivated startup, advanced a small amount of sewage in reactor drum, liquid level should not surpass 0.5 meter, opens submersible agitator, begins the cultivation of algae; When the sewage color obviously changes green, the algae culture success; When significantly descending appearred in organic concentration to sewage, algae-bacteria symbiotic system formed.Repeatedly water inlet on a small quantity afterwards slowly promotes the interior liquid level of reactor drum, finally makes liquid level reach design water level.Start membrane filtration system at last, realize being back to back water, when biological concentration reaches design requirements in the question response device, accomplish the debugging of whole built-in film symbiosis reaction unit, get into steady running.
Described built-in membrane filtration system comprises vacuum pump, mould material assembly, pickling tub, alkali cleaning pond, clean water basin, instrument, valve.
Built-in film symbiosis reaction unit of the present invention has following advantage:
1, keeps the biological concentration that is difficult for settled algae in the reactor drum through membrane filtration system, thereby strengthened the algae-bacteria symbiotic system of occurring in nature, realized that the reinforcement of nature self-cleaning system is bionical.
2, than the traditional wastewater biological treatment, need not oxygen supply, save energy consumption.In addition,, reduce investment outlay need not to need not the drum Ventilator Room under the condition of oxygen supply, and the operation noiseless.
3, startup and operation are simple, comparatively are adapted at the area, small towns and apply.
4, relative traditional activated sludge process, a large amount of absorbed nitrogen phosphorus of algae synthesis of organic substance is difficult for discharging repeatedly, can realize the steady removal to eutrophication materials such as nitrogen phosphorus.
