Industrial wastewater treatment system

Nowadays, the industrial zones have become more and more developed, accompanied by such rushing development as the increasing amount of wastewater discharged into the environment, causing serious environmental pollution. Therefore, the demand for industrial wastewater treatment is indispensable here. In the industrial zones, the wastewater consists of two main types: wastewater from factories in the industrial park and waste water from the living quarters, toilets, offices ...

Daily-life wastewater is very stable in terms of components, however, production wastewater is frequently changed in terms of properties as well as composition. Domestic wastewater polluted mainly by COD, SS, N, P, BOD5, fat, etc., while wastewater produced in industrial zones is only determined in each production item. Specifically. Therefore, for factories and workshops, it is necessary to build a wastewater treatment system before discharging wastewater into the sewage system of the industry.
Industrial waste water treatment
The amount of wastewater generated from the workshops in the IZ leads to the sewers of the wastewater treatment plant under the drainage network. In these pits, to protect the pipeline network, the traps are installed in the pit to remove large-scale impurities from the effluent. After this, the amount of waste water will be pumped into the air conditioning tank. In front of the air-conditioning tank, the garbage bins are installed to remove the remaining suspended solids before letting the water flow into the regulating tanks. (The size of the refuse trap is 1mm, Small size reduces SS by 15%.
In the air conditioning tank, the gas distribution system will mix waste water throughout the tank area, preventing deposits in the tank generated unpleasant odors, while also regulating the flow and concentration of water. Discharge of inputs. Wastewater from the air-conditioned tank is pumped into the reactor. At the reactor, the flocculant was injected into the tank at a certain dosage and tightly controlled by a chemical dosing pump. Under the effect of a large-scale agitator system installed in the tank, the agglomerates are quickly mixed and disposed of in the wastewater. This wastewater mixture itself flows through a cotton-seedling tank.
Under the effect of coagulants and stirring motor systems at a slow speed, the dregs will move, collide, coalesce and form deposits of large size and mass. initial deposits, which facilitate sedimentation in sedimentation tanks. Water and cotton mix in the coagulating tank makes self-flowing cotton to the settling tank. The slurry in the wastewater mixture is retained at the bottom of the settling tank. The sludge is pumped through the sludge tank, the water after the sludge separates into the intermediate tank and then pumped into the SBR tank. Here, oxygenated microorganisms will use organic matter for growth. SBR is a combination tank between aerobic and sedimentation tanks so no sludge is required.
The water collected in the SBR tank is pumped through a multi-layer pressure filter tank: gravel, quartz sand and activated carbon to remove dissolved organic compounds, trace elements , difficult or non-biodegradable substances. After passing through the filter tank, the wastewater passes through the dry nano tank to remove the remaining amount of SS in the wastewater and disinfect the wastewater. Water after passing through dry-type nanoparticles meets the requirement of discharge into receiving sources according to current law provisions.
Sludge in the sludge tank is pumped through a conveyor belt slurry machine to remove water, reducing the volume of sludge. The dry dregs are collected and processed periodically by functional agencies. In the sludge tank, the air is supplied to the tank to avoid the odor generated by the biodegradation of organic matter.
