Description
Technical field
The present invention relates to field of environmental improvement more particularly to a kind of sewage water treatment methods.
Background technology
In recent years, it is carried out in a deep going way with new countryside construction, by implementing graceful small towns construction and rebuilding old villages and village
Great changes have occurred in training works, the villages and small towns infrastructure construction of China some areas and environment looks.At the same time, rural area
The problem of sanitary sewage discharge unordered, welding, increasingly causes extensive concern.But country sewage collection for a long time is handled
System is not perfect, and waste water collection rate and handling rate are low, seriously affects local water environment and the looks of integrated environment, and endanger city
The safety of water supply.Rural Water Environment present situation has several features at present：
The first, lack sewage collecting and treatment facility, sewage are in line.The small market town in 95% or more village of China and 90% or more
All imperfect sewage collecting and treatment facility, the sanitary sewage and part industrial wastewater of generation, almost without any place
Reason is directly discharged into the water body in villages and small towns（River, pond, underground water etc.）, cause the serious pollution of villages and small towns water body.
The second, water pollution is serious.Since sewage is directly discharged into water body for a long time, villages and small towns water body is usually smaller in addition, in river
The mobility of southern area water body is also smaller, and environmental carrying capacity is extremely limited, caused by result be exactly not only water body lose it is due
Function, and it also seriously destroys the integrated environment and landscape in villages and small towns.The lake of black-odor riverway, pond and eutrophication has become
The universal phenomenon for the south of the lower reaches of the Yangtze River that beautiful environment in the past.
Third, water environment pollution and destruction also will produce related polluting effect, unhealthful.Studies have shown that many diseases
Generation be all of close concern to each other with water environment.Water pollution is possible to promote the generation of some malignant diseases.
4th, lack targetedly advanced and applicable sewage disposal technology.Since villages and small towns sewage is with displacement children point
It dissipates, the features such as variation water quality is bigger, and compared with city, difference of the villages and small towns in the conditions such as society, economic and technical,
More mature municipal sewage technique should not be used in the sewage disposal of villages and small towns, and some so-called environmental techniques tend not to completely
Sufficient processing requirement, or lack the condition implemented（Such as land resource）.
Invention content
In view of the above problems, the present invention provides a kind of sewage water treatment method, this method concise in technology, treatment effects
Good, occupation of land saves, low energy consumption, operational management is easy, secondary pollution is few.
In order to solve the above technical problems, a kind of sewage water treatment method provided by the invention, is made of following steps：
（1）The tilting pipeline that sewage is built-in with multiple tracks barrier by one first makes large-scale particulate matter in sewage, miscellaneous
Matter is stopped by barrier；
（2）Sewage is entered in aerobic nitrification pond；
（3）Aerobic nitrification pond will be passed through then into zeolite reaction tank；
（4）It, by the promotion of pump, will be entered in combined biofilter by the sewage in zeolite reaction tank；With
Biomembrane therein is come into full contact with；
（5）It will be entered in stripping tower by the sewage in combined biofilter；
（6）The sewage for entering later in stripping tower is entered into artificial wet land system；
（7）Purification water outlet.
The step（1）Described in the quantity of barrier be at least 4 layers, and the through hole of later layer barrier is respectively less than previous
Layer barrier.
The step（5）In stripping tower in wooden or plastic slat filler is installed.
The sewage water treatment method of the present invention, combines multiple screening system and nitrogen phosphorus processing system, has effluent quality
Well, have the advantages that stronger nitrogen phosphorus processing capacity, operation and maintenance are convenient, management is simple, investment and operating cost are low, compare suitable
The Small Urban and rural area that, energy shortage few together in fund and technician lack.
Specific implementation mode
Using specific implementation mode below, present invention will be explained in further detail.
A kind of sewage water treatment method, is made of following steps：
（1）The tilting pipeline that sewage is built-in with multiple tracks barrier by one first makes large-scale particulate matter in sewage, miscellaneous
Matter is stopped by barrier；In this step, the quantity of barrier is at least 4 layers, and the through hole of later layer barrier is respectively less than preceding layer
Particulate matters more as possible, impurity can be intercepted on barrier, be beaten for subsequent sewage purification by barrier, such structure setting
Lower basis.
（2）Sewage is entered in aerobic nitrification pond, mainly under aerobic condition, passes through nitrite bacteria and nitric acid
The effect of salt bacterium, by the ammonium oxidation in sewage at nitrite nitrogen and nitrate nitrogen；
（3）Aerobic nitrification pond will be passed through then into zeolite reaction tank, in practical application, zeolite reacts
Zeolite in pond mainly has well-regulated pore passage structure and hole with clinoptilolite in the three-D space structure of clinoptilolite,
The excellent performances such as sieve effect, small ring adsorptive selectivity, thermal stability and shape stability are made it have, for the middle ammonia nitrogen of sewage
Removal and adsorption capacity it is stronger.
（4）It, by the promotion of pump, will be entered in combined biofilter by the sewage in zeolite reaction tank；With
Biomembrane therein is come into full contact with, after the procedure, a large amount of pollutants in sewage can by by microorganism adsorption simultaneously
Degradation；
（5）To be entered in stripping tower by the sewage in combined biofilter, ammonia nitrogen in waste water mainly with
Ammonium ion (NH4+) and free ammonia (NH3) state exist, and equilibrium relation is as follows：This pass NH3+H2O-NH4++OH-
System is influenced by pH value, and when pH value is high, balance is moved to the left, and the ratio of free ammonia increases, when room temperature, when pH value is 7 or so
When most of ammonia nitrogen exist with ammonium ion state, and when pH is 11 or so, free ammonia substantially accounts for 98%, and free ammonia is easy to from water
Effusion.
Ammonia-nitrogen stripping tower generally uses double tower series winding operation, to improve the recycling concentration of ammonia.And it is installed behind stripping tower
Ammonia nitrogen absorption tower greatly reduces the ammonia and nitrogen components in sewage after so that the ammonia nitrogen exhaust gas that stripping comes out is handled by absorption tower.
（6）Sewage later in stripping tower will be entered and enter artificial wet land system, artificial swamp is a kind of with relatively wide
The New Technology about Wastewater Treatment of general application, its main feature is that effluent quality is good, has stronger nitrogen phosphorus processing capacity, operation and maintenance side
Just, management is simple, invest and operating cost is low, is relatively more suitable for the middle small city that few fund, energy shortage and technician lack
Town and rural area.But, traditional Artificial Wetland Techniques there is also treatment effeciency relatively low, floor space mistake similar with Efficiency for Soil Aquifer Treatment
Greatly, it is easy to block the shortcomings of causing systemic breakdown.But the concrete condition in China villages and small towns is engaged, it can be by artificial swamp
Structure and filling system are improved, and form high-throughput Artificial Wetland Techniques, by itself and other advanced treatment technology optimum organizations,
It as a kind of subsequent processing technology, can both overcome artificial wet land system easily to block take up a large area Deng inherent defects in this way, protect
Card system normal operation, and effluent quality can be improved, while can also beautify the environment.
（7）Purification water outlet.
