The solid-liquid separation includes primary filtration and reverse-osmosis treatment. The reclaimed water reuse and treatment process has the advantages such as good effect in water treatment and low operation cost, and water treated by the process reaches the standards.
Description
Technical field
The present invention relates to technical field of sewage, be specifically related to a kind of Treated sewage reusing and process technique.
Background technology
Waste water, waste gas enter river, river, lake, Hai Hou, severe contamination water body.Many hotels, restaurant and Scenic Spots, holiday village all have sewage treatment facility, and through the water outlet that sewage treatment facility processes, water quality can reach the standard of two grades of discharges.But reach the waste water of secondary discharge standard, can not reuse, in addition it is also necessary to carry out advanced treating.
At present, technique for sewerage disposing substantially can be divided three classes: one is physical treatment process, generally use membrane filter technique, membrane filter technique is under the effect of external force, the solution separated is flowed along filter membrane surface with certain flow velocity, in solution, solvent and low molecular weight substance and inorganic ions enter low-pressure side from high-pressure side through filter membrane, and discharge as filtrate；And polymer substance, colloidal particles and the microorganisms etc. in solution are retained by ultrafilter membrane.Two is physical-chemical process, it is adaptable to the situation that sewage quality changes greatly, and typically uses the methods such as sand filtration, activated carbon adsorption, flotation, coagulating sedimentation.Three is biological treatment, it is applicable to the sewage disposal that content of organics is higher, typically use the bioremediations such as activated sludge process, contact oxidation method, biological rotating disk, or be used alone, or several bioremediation is applied in combination, such as flow processs such as catalytic oxidation+biofilter, biofilter+activated carbon adsorption, rotating disk+sand filtrations.
In prior art, advanced treatment of wastewater occupation area of equipment is big, and investment is many, and the construction period is long, fluctuation of service, and the water outlet processed can not reach reuse standard.
Summary of the invention
For solving the problems referred to above, the invention discloses a kind of Treated sewage reusing and process technique, high treating effect, operating cost is low, water quality reaching standard.
In order to achieve the above object, the present invention provides following technical scheme:
nullA kind of Treated sewage reusing processes technique，This technique is former water with Wastewater Form Circulating Cooling Water，Pollutant in described former water are reducing substances and graininess rubbish，Described reducing substances includes Organic substance、Nitrite、Sulfide and ferrous salt，This technique includes bio-contact oxidation and solid-liquid separation，Described bio-contact oxidation is carried out in contact-oxidation pool，Described contact-oxidation pool includes a biochemistry pool and secondary biochemistry pool，Polymer fiber element ether filler it is respectively equipped with in a described biochemistry pool and secondary biochemistry pool，Described polymer fiber element ether filler arranges active microorganism，Described active microorganism includes anaerobic bacteria and aerobic bacteria，Described aerobic bacteria is arranged on the filler in a biochemistry pool，Sewage is carried out once biochemical by aerobic bacteria，Described anaerobic bacteria is arranged on the filler in secondary biochemistry pool，It is biochemical that anaerobic bacteria carries out secondary to sewage；Described solid-liquid separation includes once filtering and reverse-osmosis treated.
As a further improvement on the present invention, the described process once filtered is successively through active carbon filter, accurate filter and MBR membrane bioreactor.
As a further improvement on the present invention, the pH value of described former water controls at 5.5-6.5.
As a further improvement on the present invention, the concentrated crystallization apparatus of regeneration flushing water after described reverse-osmosis treated processes, and condensed fluid uses as boiler fired coal desulfurizing agent as recycle-water, residue.
As a further improvement on the present invention, before raw water to contact-oxidation pool, first former water is imported a grille well, and utilize basket filter to filter, remove graininess rubbish.
The present invention is compared with prior art, have the beneficial effect that: the present invention utilizes aerobic, anaerobe to decompose the organic substance in sewage, the inorganic substances such as the nitrite in water, sulfide and ferrous salt are adsorbed, multiple filter is utilized sewage solid to be separated with reverse-osmosis treated, the clear water meeting city integrated discharge primary standard can be obtained, can be as Treated sewage reusing, required equipment advanced treatment of wastewater occupation area of equipment is few, construction period is short, stable.
Detailed description of the invention
The technical scheme provided the present invention below with reference to specific embodiment is described in detail, it should be understood that following detailed description of the invention is merely to illustrate the present invention rather than limits the scope of the present invention.
A kind of Treated sewage reusing processes technique, this technique is former water with Wastewater Form Circulating Cooling Water, pollutant in described former water are reducing substances and graininess rubbish, described reducing substances includes Organic substance, nitrite, sulfide and ferrous salt, controls the pH value of former water at 5.5-6.5 by adding acid or alkali.
This technique mainly includes bio-contact oxidation and solid-liquid separation, bio-contact oxidation is carried out in contact-oxidation pool, contact-oxidation pool includes a biochemistry pool and secondary biochemistry pool, polymer fiber element ether filler it is equipped with in biochemistry pool and secondary biochemistry pool, polymer fiber element ether filler arranges active microorganism, utilize microorganism that the Organic substance in sewage is decomposed, active microorganism is divided into anaerobic bacteria and aerobic bacteria two kinds, aerobic bacteria is arranged on the filler in a biochemistry pool, realize aerobic bacteria and sewage is carried out once biochemical, anaerobic bacteria is arranged on the filler in secondary biochemistry pool, it is biochemical that anaerobic bacteria carries out secondary to sewage.
After secondary biochemistry, then carrying out solid-liquid separation, in the present invention, solid-liquid separation mainly includes once filtering and reverse-osmosis treated, and the process once filtered is successively through active carbon filter, accurate filter and MBR membrane bioreactor.The concentrated crystallization apparatus of regeneration flushing water after reverse-osmosis treated processes, and condensed fluid uses as boiler fired coal desulfurizing agent as recycle-water, residue.Water outlet COD≤1mg/L after reverse-osmosis treated, total hardness≤0.5mg/L, total alkalinity≤6mg/L, chloride ion≤7mg/L.
