Sewage and Wastewater Treatment Devices {SEWAGE, DIRTY AND WASTE WATER TREATMENT DEVICE}

The present invention relates to a sewage and wastewater treatment device, and more specifically, to provide more than two tanks of wastewater and wastewater reaction tanks to sequentially distribute and stably treat the incoming wastewater and wastewater. The present invention relates to a sewage and sewage treatment apparatus which allows the material to be discharged from the discharge tank by the collecting means, and the sediment mixed in the waste water is easily removed by the sediment removing means.

In general, nutrients contained in sewage and wastewater are inorganic elements necessary for the growth and proliferation of microorganisms that cause the decomposition of organic substances. Among them, nitrogen compounds and phosphates are continuously used for biological cell formation and life energy acquisition. Is the element to be supplied.

However, when nutrients such as nitrogen and phosphorus increase in rivers, coastal seas and lakes, the nutrients that activate nutrient-based organisms produce red tide in the sea and green algae in the lake. Happens.

This process is smooth in the natural world, but living sewage, livestock waste, and factory wastewater

If the back is introduced in large amounts, the nutrients increase and accordingly the suspended substances are mixed in large quantities to paralyze the natural purification ability.

As a result, eutrophication progresses rapidly, lowering the utilization of water resources and destroying ecosystems.

Therefore, nutrients from various wastewaters should be removed before they enter the sea, appeals, and streams to prevent eutrophication and nutrient removal methods have been developed to prevent them efficiently.

In Korea, most sewage and wastewater treatment facilities remove organic substances. In other words, the active sludge method, its transformation method, and catalytic oxidation method are mainly used to remove organic matters and suspended solids, and are not suitable for the nitrogen and phosphorus removal process recently known as eutrophication agents of rivers and lakes.

Therefore, recently, a method for removing nutrients has been developed and applied. The treatment process arranges anaerobic tanks, anaerobic tanks and aerobic tanks, and internally returns them according to the operating conditions of the tanks. Remove it.

The methods include VIP, SBR, A2O, and UCT, which are selected by considering the sewage and wastewater characteristics of the region and economic feasibility. I use it.

However, these processes have a lot of unit processes to remove nitrogen and phosphorus, and it requires a lot of facility cost, power cost, and maintenance cost according to the internal return for nutrient removal, and there are many additional facilities in converting existing facilities to advanced treatment. Difficulties in construction and a lot of site for the process facility is a problem.

In addition, the sewage and wastewater reaction tank is composed of one tank, and the sedimentation of the waste due to the continuous inflow of wastewater does not occur, and there is a problem in that untreated wastewater and purely purified wastewater are mixed.

The present invention has been devised to solve the above problems, and its purpose is to perform anaerobic and aerobic treatment in one sewage and wastewater reaction tank, and to provide inflow of sewage and wastewater having two or more tanks. The present invention provides a sewage and wastewater treatment apparatus for distributing the sewage and treating the sediment sequentially to achieve stable denitrification and dephosphorization.

In addition, another object of the present invention is to remove the sediment mixed in the waste water and waste water very easily with the sediment removal means, and the waste water treatment to discharge the purified water purified in the waste water reaction tank by the collecting means. In providing a device.
