Description
Technical field
The present invention relates to sewage treatment area, relate in particular to a kind of magnetic separation technique, fixed biologically bed water treatment system and treatment process.
Background technology
Along with the high speed development of industrial and agricultural production and the raising day by day of living standards of the people, more and more yearn for " blue mountains and green waters " living environment like poetry picturesque, yearn for the natural beautiful scenery of " bluish waves swing appearance, peaceful and charming environment ".In urban green space, construction of park and the large-scale landmark building, artificial lake, sloot and landscape pond continue to bring out.Because the factor affecting such as intrusion of design management, xenobiotic pollutants, the eutrophication problem of water body is increasingly serious.According to statistics, the lake over half in the world and the water quality of reservoir are worsened because of polluting constantly, and the liquid fresh water of earth surface 90% is from these lakes and reservoir.Along with the continuous increase of world population, the problem of water resources maybe be with further worsening.With Beijing Environmental Protection Administration statistics in 2010 is example, monitors 17 in water lake the whole year altogether, and totally 8 in II, III class water quality lake account for 49.3% of monitoring lake area; 24 in IV class water quality lake accounts for 10.2% of monitoring lake area; Totally 2 in V class water quality lake accounts for 10.2% of monitoring lake area; 5 in bad V class water quality lake accounts for 30.3% of monitoring lake area.
There is comparatively serious little contamination phenomenon in landscape water body, as not controlling, will certainly cause the deterioration of whole lake region water quality; Therefore, build manmade landscape, artificial landscape's river sewage and handle, the local water resources of recycle; To protecting local ecotope all will produce great economy, society, environment, ecologic effect; The whole society should from politics, pay attention to water resources problems legally, with economical means management of water resource, and pay attention to water-saving education and measure in the whole society.In addition, do one's utmost to advocate conservation-minded society now, development of the present invention also has very big meaning to economizing on resources, and therefore has good economic benefits and social benefit.
Summary of the invention
The objective of the invention is to disclose a kind of magnetic separation technique, fixed biologically bed water treatment system and treatment process; Be primarily aimed at the processing of polluted water such as lake, river course, small watershed water body, the water outlet after the processing reaches cities and towns purification of water quality plant effluent one-level A or one-level B standard.
Goal of the invention of the present invention is to realize by the following technical programs.
The present invention discloses a kind of magnetic separation technique, fixed biologically bed water treatment system, and this system comprises: magnetic separates waste water purification system, fixed biologically bed; Described fixed biologically bed is to fill the argillous manual work of certain mixing to construct groove, comprising iron particle or iron chip.
The magnetic separator that described magnetic separates in the waste water purification system is a disk.
Also fill carrier in the described fixed biologically bed with strong absorption property; Said carrier is meant natural zeolite, coke, volcanics.
Can also be filled with in the described fixed biologically bed and be beneficial to fixed nitrogen or water purifying plant-animal.
Described fixed biologically bed is provided with aerating apparatus in the middle layer.
The present invention also discloses a kind of magnetic separation technique, fixed biologically bed water treatment method, polluted water is carried out pre-treating technology after, separate waste water purification system through magnetic, flow into the fixed biologically bed after the water outlet water distribution and handle, the water body after the purification is discharged.
Described pre-treating technology is meant grid, catchments.
Can be drawn by technical scheme disclosed by the invention, the present invention has following characteristics:
1, do not produce active sludge, the processing costs of saving active sludge can not cause because of activated sludge disposal is improper to cause second environmental pollution.
2, investment cost is economized, and the direct construction cost of ton water that the present invention handles the ton project is about 800～1200 yuan/ton.
3, working cost is low.The working cost of treatment process of the present invention is 1/3rd of a general activated sludge process working cost.
4, water outlet effect is superior to traditional activated sludge process, all can reach cities and towns purification of water quality plant effluent one-level A or B standard.
5, be convenient to operation, be easy to administer and maintain, alleviated labor intensity of operating personnel.
6, anti-shock loading is strong, can handle COD less than the good water body of 800mg/L biodegradability; For sink drainage out of service after, the fixed biologically bed system can recover normal operation rapidly in 3～5 days.
7, process system noiseless does not have obvious stink, does not influence surrounding enviroment.
8, the present invention fully keeps the advantage of magnetic separation technique efficient dephosphorization, is reducing further the raising COD and ammonia-N removal rate on the running cost basis.
The usefulness of magnetic separation waste water purification system mainly is to remove suspended substance (SS), total phosphorus (TP) and portion C OD in the water among the present invention, improves the filter infiltration rate degree of fixed biologically bed, prevents to stop up, and reduces the processing load of biological of subsequent fixed simultaneously.
Fixed biologically bed treatment process belongs to a kind of technology that polluted water land is handled, and is provided with aerating system at the middle part, makes filler or carrier space be in aerobic state, and is in anaerobic state in the mixed soil soil block.Sewage make pollutent be able to remove through producing comprehensive physics, chemistry and biological respinse in the process, wherein mainly is biochemical reaction, and alternately the helping of aerobic and anaerobic condition purifies waste water effectively.Aerobic condition can promote nitration reaction, organic degraded, ferrous ion to be oxidized to the ferric iron that is easy to phosphorus generation precipitin reaction down; Anti-nitration reaction takes place down in anaerobic condition; Simultaneously be minimized total nitrogen by packing layer and supporting vegeto-animal absorption nitrogen fixation; Ammonia nitrogen, portion C OD in final removal or the curing water body, the water body discharging after the purification.
