Technics Processing:

The collected domestic sewage pass by grilling, remove bigger suspended matter,seston and ribbon in water, flow into regulating tank, set regulating tank purpose is regulate sewage volume and quality, in order to prevent suspended matter sediment in regulating tank, it equipped with aeration pipe in the bottom of regulating tank, using intermittent aeration. the effluent water from regulating tank will enter into primary settling tank and three level biochemical tank by lifting pump, proceed biochemical treatment. The Organic Ingredients is high in such sewage project, BOD5 /CODcr≈0.5, with better biodegradability, so adopt biological treatment manner reduce organic content is most economical, because the ammonia nitrogen and organic content is high in sewage , especial organic nitrogen ,in biological degradation organic matter , organic nitrogen will display in ammonia nitrogen form, ammonia nitrogen is important pollution control index ,so sewage treatment adopt Biological Contact Oxidation, biochemical tank need divide into primary settling tank and three level biochemical tank two parts. Inside of primary settling tank , due to organic matter content is high, Microbes in anaerobic condition, at this time, microbes is facultative microbes, they make the organic nitrogen into ammonia nitrogen in sewage , Use of organic carbon source as electron donor, make convert into N2 ,and adopt parts of organic carbon source and ammonia nitrogen synthesis new cells material. So the primary settling tank has the function of organic matter removal, reduce organic loading of subsequent three level biochemical tank, good for proceeding nitrification , and rely on high content organic matter in sewage ,finish denitrification, final eliminate nitrogen eutrophication pollution. After pass by primary settling tankbiochemical action, the sewage still contain some organic matter and higher content ammonia nitrogen. in order to make the organic matter further oxygenolysis, at the same time, carbonation tend to be completely, nitrification can proceeding smoothly, so set three level biochemical tank, its rely on Autotrophic type bacteria finish treatment, they adopt Organic decomposition producing inorganic carbon source or carbon dioxide in air as nutritional sources, make the ammonia nitrogen in sewage convert into . In primary settling tank and three level biochemical tank all install padding, the whole Biochemical process rely on many microbes attached on the padding. The dissolved oxygen in primary settling tank is control around 0.5mg/L, but in three level biochemical tank the dissolved oxygen is above 2mg/L,some effluent water from three level biochemical settling tank back flow into regulating tank proceeding internal Circulation, so achieve denitrification purpose, another parts will flow into secondary settling tank, proceeding solid-liquid separation, the effluent water after separated will enter into disinfecting tank, the effluent water afterdisinfection treatment will reach to standard and discharge into nearby waters.

 

(1)Grilling well: remove branch,plastic etc Larger impurities.

 

(2)Regulating tank: homogenize water volume and quality.

 

(3)Primary settling pond:the sewage ascending flow rate in this tank is 0.2-0.3mm/S, the settling sludge will lifting to sludge storage tank by Solid air lift.

 

(4) Contact oxidation pond: the primary settling sewage will flow into here proceeding biochemical treatment, it can divide three-level, the total retention time is 4-6h, padding is novelty elastic padding, easy to membrane, no blocking, padding/surface area is 160m2/m3, gas-water ratio is about 12:1.

 

(5) Second settling pond: the sewage after biochemical treatment will flow into second settling pond, ascending flow rate is 0.1-0.15mm/s,surface loading less than 1.0m3/m2.h, discharge sludge using air lift to sludge storage tank.

 

(6) Disinfection pool: add chemical agentia,such as liquid chlorine  or Sodium Hypochlorite etc.

 

(7) Sludge storage pond: all sludge in the primary settling pond and second settling pond need air lifting to sludge storage pond, then proceeding aerobic digestion, the supernatant liquor in sludge storage tank backflow into contact oxidation pond reprocessing , the surplus sludge is very little, it need clean 1 time every 1-2 years usually, cleaning manner can be use fecing suction truck stretch into sludge tank bottom from manhole of sludge storage tank sucking it and transport outward.

 

(8) Fan room: it set up above the sterilization tank, its inlet adopt two layer sound-proofing, the air intake has muffler ,fan filter, no noise when operation, air blower adopt two units L type roots blower , which can automatic replace operation, unit blower operation life about 30000h.

Used in sewage treatment plant

STEP ONE - The first step for the raw sewage when it reaches the Wastewater Treatment Plant is the removal of heavy particles from the liquid. This happens in the Grit and Screen Building. Here, the sewage passes through a screen system to remove any material greater that 12.5 mm in size.    This material is removed and transported to the landfill.  The wastewater then passes through a centrifical grit removal system. 

STEP TWO - The wastewater then travels to the Primary Sedimentation Basins where its speed is reduced even further. This allows fine particles to settle. The settling process divides the materials into settled material at the bottom of the basins, called sludge, and wastewater.

The sludge is moved to hoppers at the ends of the tanks by scrapers and is sent to the Fermenters (large, closed tanks with mixing mechanisms). Here, Volatile Fatty Acids (VFAs) are created through fermentation (a chemical process that breaks down organic matter). These VFAs are then used in the next stage of treatment.  Small amounts of fermenter sludge is periodically wasted to the Digesters to ensure the continued success of the fermentation process.

As the wastewater leaves these basins, any floating grease or scum is skimmed from its surface and sent to the Digesters. The wastewater, now called primary effluent, is pumped to the Bioreactors.

STEP THREE - The bioreactors are a state-of-the-art Biological Nutrient Removal (BNR) facility. The wastewater is treated by using micro-organisms instead of traditional chemical methods to break down the unsettled particles and nutrients. The micro-organisms do this by using the nutrients in the wastewater as a food source. VFAs created by the fermenters are used in this process by some of the micro-organisms. The process of BNR is environmentally friendly and helps ensure a cleaner, more natural final product.

STEP FOUR - After nine hours in the Bioreactors, the effluent flows by gravity to the Secondary Clarifiers. Here the micro-organisms in the wastewater settle to the bottom and are returned to the Bioreactors.

STEP FIVE - The clear effluent from the Secondary Clarifiers flows through the UV Disinfection system. Finally the treated effluent flows over a weir and into the South Saskatchewan River.

STEP SIX - The sludge and/or scum removed from the Primary Sedimentation Basins, Fermenters and Secondary Clarifiers will remain in the Digester at 35 degrees Celsius for approximately 20 days. Because there is no oxygen present in the Digesters, it is an anaerobic process and the bacteria begin to produce methane as they break down the sludge. The methane is used as a fuel for the boilers in the Heating Building that heat the Wastewater Treatment Plant.

STEP SEVEN - Stabilized sludge, the end product from the digestion process, is pumped 12 kilometres north of the Plant and is stored in deep ponds. Twice a year the sludge is pumped out and spread on farmers' fields by a process called liquid injection. The sludge is an excellent soil conditioner adding nutrients and moisture.

Highly trained Plant operators in the control room closely monitor all aspects of the Wastewater Treatment Plant, twenty-four hours a day, seven days a week. The on-site laboratory continuously tests the processes to ensure that the water going back into the river meets or exceeds environmental criteria.
