Description

Wastewater Treatment System {Equipment for the treatment of waste liquid}

The present invention relates to a wastewater treatment apparatus, and more particularly, to a wastewater treatment apparatus for treating wastewater containing waste printing ink generated at a printing plant or wastewater containing oil such as lubricating oil generated at a general plant.

In general, since a printing factory prints various printed matters using aqueous or oil ink, waste water containing waste ink is generated, and oil such as lubricating oil is introduced into the waste water according to operation of the printing machine. Wastewater containing such waste oil has been generated in a general machine shop.

Conventionally, in order to prevent environmental pollution caused by such factory wastewater, waste ink or oil contained in the wastewater is filtered or purified by using a filter or sedimentation method using sewage treatment or chemicals.

However, the method of using the filter has a problem that must be retreated, such as incineration, because if the waste filter is filtered as a variety of sludge, such as waste ink particles or oil particles, as it is reduced to the original waste water when water is added. In addition, the sedimentation method using chemicals has a problem of polluting the stream when it is discharged as the biological oxygen demand (BOD) is insufficient as well as the cost burden and the sediment should be retreated. As a result, in many cases, the factory wastewater is discharged as it is, and as a result, wastewater flows into general sewage and rivers, and contaminates soil and water, thereby destroying the natural environment.

In addition, when wastewater flows into the combustion chamber in the gas in which the inlet of combustible general waste disclosed in Korean Patent Laid-Open Publication No. 98-1841 and the outlet of combusted ash and the exhaust port of combustion air are introduced, water is evaporated and the sludge contained A processor equipped with a burner for incineration, a feeder for supplying the wastewater to be treated to the processor side, a spout for discharging the wastewater supplied by the feeder into the combustion chamber through a nozzle, and an outlet of the processor. There is a wastewater treatment apparatus characterized by including a dust collector for collecting dust and the like contained in the discharged gas discharged, but this is a vertical combustion chamber, using one burner, and incineration within a short combustion time, There was a limit.

Therefore, the present invention has been devised to solve the above problems, and an object of the present invention is to provide a more efficient wastewater apparatus in wastewater treatment by providing a sufficient combustion time in the combustion chamber and operating an auxiliary burner according to the combustion state. have.

Another object of the present invention is to provide a wastewater apparatus further comprising a facility for cooling the exhaust gas.

Still another object of the present invention is to provide a wastewater apparatus further comprising a facility capable of efficiently saving fuel and utilizing waste materials.

The above object of the present invention is to completely incinerate and remove sludges such as waste oils such as aqueous or oily waste printing ink contained in plant wastewater, lubricating oil, cutting oil, etc., and evaporate the water to eliminate the need for reprocessing. In the apparatus, the space of the combustion chamber was formed in two or more stages, and two or more burners were installed, and the nozzle was equipped with the spray nozzle which sprays waste water from a nozzle into fine particles.

Another object of the present invention was achieved by installing a cooling pipe or a watering device in the combustion chamber outlet pipe.
