Description
Technical field
The present invention relates to sewage water treatment method, and in particular to a kind of multi-stage sewage processing method.
Background technology
With cities and towns expanding economy, villages and small towns population is constantly concentrated, and township enterprise develops rapidly, town sewage discharge capacity
It is continuously increased, yet with the outdated ideas of past " reconstruction is set, light environmental protection ", cities and towns infrastructure construction lags far behind cities and towns and built
If development, lack necessary sewage collection system and sewage treatment facility, the unordered sinuous flow of sewage, not only directly pollute cities and towns
Itself ecological environment, and cause the serious pollution of water bodies of rivers and lakes, it has also become the important pollution sources of regional water environment.Together
When, because samll cities and towns are close to the pollution of area source such as rural area, livestock and poultry cultivation, aquaculture, agricultural chemicals and chemical fertilizer also extremely seriously, to city
Town drinking water safety and resident's living environment constitute a serious threat, and constrain economic development and Town Sustainable Development.
COD (COD or CODcr) refers to that under conditions of necessarily strictly the reducing substances in water is additional
In the presence of strong oxidizer, the quantity that oxidant is consumed when decomposing is oxidized, is represented with the mg/L of oxygen.COD reflects
The degree polluted in water by reducing substances, these materials include organic matter, nitrite, ferrous salt, sulfide etc., but one
As in water and waste water inorganic reduction material quantity it is relatively little, and be very universal by Organic Pollution, therefore, COD can
A composite target as organic substance relative amount.
Many chemical plant social now, discharge the higher sewage of a large amount of COD contents, thus, how rapidly and efficiently to COD
The higher sewage of content is handled, and is recycled, and turns into an important topic.
The content of the invention
The problem of existing for prior art, the present invention provide a kind of sewage water treatment method with acidification, utilize
Hydrolysis acidification pool, biological contact oxidation pond and multiple settlers combine design, can be good at handling sewage, and economic ring
Protect, it is convenient and swift.And wastewater ocean disposal after handling, energy-conserving and environment-protective.
The technical scheme is that：A kind of sewage water treatment method with acidification, is comprised the following steps that：
Step 1: sewage is introduced into grid pond, grid processing is carried out；
Step 2: the water in step 1 after grid is handled is passed through into aeration settling pit, the desilting of inorganic particle is carried out
Processing；
Step 3: the water in step 2 after aeration settling pit desilting processing is passed through into regulating reservoir, water quality and quantity is carried out
Homogenizing processing；
Step 4: the water in step 3 after the homogenizing processing of water quality and quantity is passed through into air-floating apparatus, carry out at air supporting
Reason；
Step 5: collecting-tank will be entered by the reacted water of air-floating apparatus in step 4, collected, stored and balanced
Processing；
Step 6: by collect in step 5 by collecting-tank, store and equilibrium treatment after water pass through the second elevator pump pump
Enter hydrolysis acidification pool, acidification is hydrolyzed；
Step 7: the water in step 6 after hydrolysis acidification is handled is passed through into biological contact oxidation pond, carries out biology and connect
Touch oxidation processes；
Step 8: the water in step 7 after biological contact oxidization treatment is passed through second pond, after sedimentation in secondary sedimentation tank
Mixed liquor feedback enter collecting-tank, form circulation, until when second pond is without precipitation, liquid qualified discharge in second pond.
Further, the grid pond described in step 1 include two, a coarse rack, a fine fack, sewage first from
After coarse rack enters the grid processing for carrying out bulky grain, enter back into fine fack and carry out short grained grid processing.
Further, connected through the reacted scum silica frost of air-floating apparatus with the sludge pipe after sedimentation in secondary sedimentation tank dense into sludge
Contracting pond, the sludge pipe connection after sludge concentration tank concentrates enter sludge dewatering squeezer, squeezed through sludge dewatering squeezer
Transported outward into mud cake.
The beneficial effects of the invention are as follows：A kind of sewage water treatment method with acidification is provided, using hydrolysis acidification pool,
Biological contact oxidation pond and multiple settlers combine design, can be good at handling sewage, and economic and environment-friendly, convenient and swift.
And wastewater ocean disposal after handling, energy-conserving and environment-protective.
