Description

Low Temperature type Waste Water Processing Apparatus}

The present invention relates to a low-temperature evaporative wastewater treatment system that evaporates wastewater and separates it into pure water.

In general, as a method of purifying industrial wastewater or livestock wastewater, there is a method of storing the wastewater in one place and then injecting a coagulant so that foreign substances such as suspended matter contained in the wastewater are entangled with each other and sedimented, and sludge (waste) There is a method of purifying the wastewater by flowing it through a screen device that filters the wastewater.

However, in the method using the coagulant described above, wastewater treatment is not perfect because the coagulant, which is a chemical agent for coagulating foreign substances, is not completely coagulated and settled, and moreover, the coagulant does not settle together with the sludge and If it remains, there is a problem of causing secondary contamination.

In order to solve this problem, recently, various wastewater, such as industrial wastewater discharged from various factories, livestock wastewater from ranches, or garbage leachate containing chemicals, is treated by heating and evaporating the wastewater without using separate chemicals or coagulants. It is called an evaporative wastewater treatment system that separates water vapor and sludge, and then reduces the water vapor to condensed water to collect pure water and sludge in a state in which water is removed.

Evaporative wastewater treatment equipment is widely used because it consumes less energy through efficient heat exchange by using a heater, evaporator, condenser, etc.

On the other hand, in the evaporative wastewater treatment system, the concentration of wastewater increases according to the continuous supply of wastewater and sludge, and the internal humidity increases in the process of generating water vapor by heating the wastewater with the moisture of the sludge and the evaporator. There was a problem in using it for a long time due to a high failure frequency, and there was a difficult problem in separating pure water from wastewater and sludge.
