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It is continuously increased, yet with the outdated ideas of past " reconstruction is set, light environmental protection ", cities and towns infrastructure construction lags far behind cities and towns and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.
Urban wastewater treatment feature：
(1) population is few, and water supply standard is relatively low, sewage disposal small scale；
(2) industrial structure region particular differences, influenceed by rainy season and water consumption hourly variation factor is larger, therefore sewage water
Amount, change of water quality are big；
(3) level of economic development is relatively low, and ability to shoulder economically is weak, and alternative applicable technology is few；
(4) cause expense for construction and operating cost too high because treatment scale is small；
(5) maintenance management technical staff and operational management experience famine etc..
The content of the invention
The problem of existing for prior art, the present invention provide a kind of multi-stage sewage processing method, at one-level machinery
Reason, secondary biochemical treatment and three-level in-depth processing combine design, can be good at handling sewage, and economic and environment-friendly, convenient and swift.
The technical scheme is that：A kind of multi-stage sewage processing method, by one-level mechanical treatment, secondary biochemical treatment and
Three-level in-depth processing is combined as a whole；Comprise 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: sedimentation basin will be passed through through overregulating the water of processing in step 3, precipitable solid in water in suspension is removed
Suspension；
Step 5: the water after being precipitated in step 4 is passed through into A/O biochemistry pools, biochemical treatment is carried out；
Step 6: the water in step 5 Jing Guo biochemical treatment is drained into coagulating basin carries out coagulating treatment；
Step 7: the water in step 6 after coagulating treatment is passed through into adsorption tank carries out adsorption treatment；
Step 8: the water in step 6 Jing Guo adsorption treatment is passed through into sterilization pool, go out to degerm, viral and parasite；
Step 9: the sludge after sterilization is drained into sludge-tank, afterwards by being recycled after sludge concentration tank.
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 4: in step 5 and step 6, at the sludge, A/O biochemistry pools after sedimentation basin precipitates
Sludge after the sludge and coagulating basin coagulation of reason is passed through sludge treating system and carries out sludge recycling.
The beneficial effects of the invention are as follows：A kind of multi-stage sewage processing method is provided, utilizes one-level mechanical treatment, secondary biochemical
Processing and three-level in-depth processing combine design, can be good at handling sewage, and economic and environment-friendly, convenient and swift.
Embodiment
A kind of multi-stage sewage processing method, one-level mechanical treatment, secondary biochemical treatment and three-level in-depth processing are combined into
One；Comprise the following steps that：
Step 1: sewage is introduced into grid pond, grid processing is carried out；Described grid pond include two, a coarse rack,
One fine fack, after sewage first enters the grid processing for carrying out bulky grain from coarse rack, it is short grained to enter back into fine fack progress
Grid processing.
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: sedimentation basin will be passed through through overregulating the water of processing in step 3, precipitable solid in water in suspension is removed
Suspension；
