PROCESS OF WASTEWATER TREATMENT TECHNOLOGY
Domestic wastewater generated from the daily life of workers, company employees + production wastewater will be collected according to the ditch system through the waste basket system. The placement of garbage baskets to retain the components of rubbish, dregs are relatively large size to avoid the impact on the rear. After separating garbage, the wastewater flows to the tank. The collectors are tasked to concentrate wastewater while grease is also retained there, periodically picking up fat to be processed. Waste water from the tank will be pumped through the air conditioning tank. In the air-conditioning tank, the air blower will provide air and uniformly mix the air throughout the tank area, preventing sedimentation in the tank producing unpleasant odors, and at the same time regulating the flow and concentration. wastewater input. Wastewater after conditioning will be pumped onto aerobic biological sludge.
In aerobic bioremediation, aerobic microorganisms use dissolved oxygen to break down and convert organic matter into waste water into biomass, carbon dioxide and water. Microorganisms are grouped together in the form of activated sludge. Dissolved oxygen is supplied from the air blower through the gas distribution system. When the source of dissolved oxygen is ensured, the biological oxidation of pollutants and the nitrification process takes place. The resulting water is cleaned and the microbial biomass is increased.
After aerobic bioremediation, the effluent will flow through the sedimentation tank to separate the microbial biomass (sludge) present in the wastewater stream. Wastewater will be distributed to the central sediment trap, the sludge will settle to the bottom of the tank, the internal water will flow over the surface and in the trough system to collect water to sterilize TB. Here, disinfectants will be pumped into the tank to destroy the harmful microorganisms present in the wastewater and at the same time oxidize the remaining organic matter in the water.
Finally, the wastewater will be pumped into a pressure filter consisting of layers of gravel, quartz sand to remove soluble organic compounds, trace elements, difficult or non-biodegradable substances. Study, create the necessary degree of waste water.
After treatment, the A-QCVN 40: 2011 / BTNMT will be discharged into the receiving environment. Solid sediment from biological sedimentation tank will be led to the sludge decomposition tank. Anaerobic sludge stabilization takes place over a long period of time, which will make the sludge stable, lose its odor and be easy to settle. From the sludge decomposition tank, the sludge is separated from the water and periodically sucked and treated. Water after the separation of sludge will circulate back to the tank to continue processing.
