Sewage treatment plant's operation unit may divide into physical, chemistry and the biological treatment three kinds.
Blocked sewage channels TK-101
Main function
The main waste water originates including buries the field water seepage, the sanitary sewage and the car wash waste water,Power
equipment is to be Blocked by him sewage channels (TK-101),Flow size to ultrasonic flow meter (FE-101) after the detection,
Transferred to the central control room, larger dirt to trash rack equipment (M-101) to remove, Trash rack equipment (M-101)
start the way (LS-101) to control by the liquidometer, avoids causing have blocking.
Leachate collection wells TK-102 TK-102
Main function
Besides will bury water seepage of interim the collection, in addition comes from the sand washing equipment
(M102/M1034), the chemical sludge concentration basin (TK-203) and the biological sludge concentration basin (TK-204) on the
clear liquid flow enters,wait until After a certain water level meter (LS-102) to detect liquid level to flow into the pump
(SP-101A / B) pumped to the subsequent processing.
Sand washing equipment M-102/M-103
Main function
Removal of seepage water contained in the sand to protect subsequent processing unit to prevent sedimentation.
Mix thoroughly pool TK-103
Main function
Seeping into the treatment system for water quality and water quantity are constantly changing, the follow-up unit of processing to
ensure uniform and stable,set mix thoroughly pool ,（TK-103）,In addition by air blower（B-101A/B）provides the aeration
maintains the suspended particulate matter does not subside, this trough has adjusts Gao Huo to lower the water quality and the water
volume, the water leakage divides into two parts,First, mix thoroughly pool water leakage pumps（SP-102A/B）provides treated water
, the other is the follow-up when the maintenance unit,Send to by returning raw water to pump to send(As SP-103s/B) send to landfill.
PH adjusts pool TK-104
Main function
his pool adding H2SO4 and NaOH products and using the pH meter (AE-101) control of wastewater pH value range of appropriate, to
facilitate coagulation reactions.
Mixes the pond quickly TK-105
Main function
In this pool in waste water by adding appropriate aggregation agent PAC (MP-303A/B) and adjust the pH value (AE-101), using fast
mixing mixer (MX-102) after rapid mixing, destruction steady state.
Cementitious pool TK-106
Main function
By adding a chemical Polymer Polymer (MP-304A/B) and the mixing device (MX-103) after adequate mixing, SS agglutination to
produce thick glue feathers, then overflow to the primary clarifier (TK-107) row solid-liquid separation, clear liquid on to the first
paragraph of anaerobic pool (TK-108A/B), scum and the underlying chemical sludge thickening of sludge to storage pools (TK-203).
Primary sedimentation tank TK-107
Main function
By adding chemical and after adequate mixing, SS aggregation into larger glue feathers, then overflow to the primary clarifier
(TK-107) do of solid-liquid separation, clear liquid on to the first paragraph of anaerobic pool (TK-108A/B), scum and the
underlying chemical sludge thickening of sludge to storage pools (TK-203).
first paragraph of anaerobic pool TK-108A/B
Main function
Anaerobic biological treatment technology of wastewater, is under oxygen-free environment, decomposition of organic matter is
due to a variety of common microorganisms,Phased manner in relay response, and finally generate CO2 and CH4,This point of view
of thermodynamics, anaerobic reaction is different oxidation / reduction of organic pollutants by type of microbial metabolism,
re-composition of organic pollutants in the highest oxidation state by microbial metabolism, re-composition of the highest oxidation
state of carbon dioxide and the highest reduction state of methane,in the pond waste water uniform mixing needs the mixer
(SMX-101A/B, SMX-102A/B) to coordinate to mix well the pond water pump (SP-102A/B) simultaneously the starting operation.
First paragraph aerobic pool TK-109A/B/C/D
Main function
After trash seeps out Water anaerobic-aerobic treatment processing, after waste water in nitrogen, phosphorus organic pollutant
elimination decrement, then uses the powdery activated carbon high contact surface area and the adsorption characteristic the
difficult decomposition the organic pollutant elimination.
Middle pool(一) TK-110
Main function
In First paragraph aerobic pool (TK-109C / D) back to the first anaerobic treatment tank (TK-108A / B).
Sedimentation tank(一) TK-111
Main function
The festivity of sewage treatment, the water delivered by gravity (TK-112A / B), scraping scum slag arm will be sent to scum
wells (a) (TK-201),produces the sludge after the gravitational settling (M-105) sweep to the mud scraper to the sludge well, a
partial backflow (VP- 106A/B) to front end biological treatment unit (TK-108A/B),A part of the waste (VP-107A / B) discharged
to the storage of biological sludge thickening tank (TK-204); return sludge pump (VP-106A / B), waste sludge pump (VP-107A / B)
And electric valve (MV-102, MV-103) by adjust evenly pool out water pump(SP-102A / B) starting close control.
The second section Anaerobic pond to enter flow well
Main function
Inlet sources including from sedimentation tank (a) (TK-111) return sludge distribution channel (TK-206), through the two brake
gate (GT-102A/B) assigned to the second paragraph after anaerobic pool (one or two) (TK-112A/B)
The second section Anaerobic pond TK-112A/B
Main function
With the anaerobic response pond (one, two)（TK-108A/B）。
The second section paragraph aerobic pool TK-113A/B
Main function
With the first paragraph of aerobic pool (1~4)（TK-109A~D）。
