Technical field
The present invention relates to sewage water treatment method, and in particular to a set of sewage water treatment method with biological rotating disk.
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It is continuously increased, yet with the outdated ideas of past " reconstruction is set, light environmental protection ", cities and towns infrastructure construction lags far behind cities and towns and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.
The biological treatment structures that biological rotating disk is made up of tank and the rotation disk body being partially submerged in sewage.Disk body
The microbial film grown on surface the repeatedly oxygen in contact groove in dirty water and air, is purified sewage.
Biological rotating disk technique is one kind of biomembrance process dirty water living creature processing technique, is the people of sewage irrigation and land treatment systems
Work is strengthened, and this facture makes a kind of microfauna of the microorganism of bacterium and mushroom, protozoan be carried in biological rotating disk filler
Growth reproduction on body, form membranaceous biological sludge --- biomembrane.Sewage connects after sedimentation basin primary treatment with biomembrane
Touch, the organic pollution in microorganism panning sewage on biomembrane is purified sewage as nutrition.Turn in pneumatic biology
In disk, the dissolved oxygen needed for microbial metabolism is supplied by being located at the aeration tube on the downside of biological rotating disk.Disc surfaces are covered with air
Cover, the compressed air-driven airhood discharged from aeration tube rotates rotating disk, when rotating disk leaves sewage, in disc surfaces
A thin layer of water layer is formed, water layer also absorbs dissolved oxygen from air.
Biological rotating disk technique is the artificial-strengthening of sewage irrigation and land treatment systems, and this facture makes the micro- of bacterium and mushroom
A kind of microfauna of biology, protozoan growth reproduction on biological rotating disk filling carrier, forms membranaceous biological dirt
Mud --- biomembrane.Sewage after sedimentation basin primary treatment with biofilm contact, in the microorganism panning sewage on biomembrane
Organic pollution as nutrition, be purified sewage.In pneumatic biological rotating disk, the dissolved oxygen needed for microbial metabolism leads to
Cross the aeration tube supply being located on the downside of biological rotating disk.Disc surfaces are covered with airhood, the compressed air discharged from aeration tube
Driving airhood rotates rotating disk, when rotating disk leaves sewage, a thin layer of water layer is formed in disc surfaces, water layer is also from sky
Dissolved oxygen is absorbed in gas.
The content of the invention
The problem of existing for prior art, the present invention provide a set of sewage water treatment method with biological rotating disk, utilize
Water acidification pool and biological rotating disk combine design, can be good at handling sewage, and economic and environment-friendly saving water resource.Multiple place of settling
Reason, sewage impurity is thoroughly removed, and recycled.
The technical scheme is that：A set of sewage water treatment method with biological rotating disk, 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 for passing through desilting processing in step 2 is passed through into water acidification pool, acidification is carried out；
Step 4: the water after progress first class purification process in step 3 is passed through into sedimentation basin, second of precipitation process is carried out；
Step 5: the water after progress secondary precipitation processing in step 4 is passed through biological rotating disk, it is net through biological sabot depth
Change is handled；
The 3rd is carried out Step 6: the water after two stage biological sabot deep purifying is handled will be carried out in step 5 and be passed through second pond
Secondary precipitation process；
Step 7: the water in step 6 after third time precipitation process is passed through sterilization pool, at sterilized pond reaction
Water after reason is emitted or recycled.
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, Step 2: in step 4 and step 6, the sludge after precipitation is passed through sludge treating system and entered
Row sludge recycles.
Further, it is provided with aeration tube on the downside of the biological rotating disk.
The beneficial effects of the invention are as follows：A set of sewage water treatment method with biological rotating disk is provided, using water acidification pool and
Biological rotating disk combines design, can be good at handling sewage, and economic and environment-friendly saving water resource.Multiple precipitation process, it is thoroughly clear
Water impurity is decontaminated, and is recycled.
