Wastewater recycling device and use method

Abstract

The invention discloses a wastewater recycling device and relates to the technical field of wastewater treatment. The wastewater recycling device comprises a water inlet pipe, a filter tank is arranged on the right side of the water inlet pipe, an acid-alkali neutralizing box is connected to the bottom of the right side of the filter tank by a connecting water pipe, an ultrasonic cleaner is connected to the bottom of the right side of the acid-alkali neutralizing box through a connecting water pipe, an ozone oxidizer is connected to the bottom of the ultrasonic cleaner, an HBR composite biochemical reactor is connected to the bottom of the right side of the ozone oxidizer through a controllable water pipe, a solenoid valve is disposed on the controllable water pipe, an ultrafiltration tankis connected to the bottom of the right side of the HBR composite biochemical reactor through a connecting water pipe, a plasma-purification activated carbon adsorption net is disposed in the inner cavity of the ultrafiltration tank, and a disinfection device is connected with the bottom of the ultrafiltration tank. The wastewater recycling device can ensure full degradation of organic matter andremove nitrogen and phosphorus, so that the water quality reaches the purification standard, chemical production wastewater is purified efficiently, the water recycling rate is improved, and economicbenefits are good.

Description

technical field [0001] The invention relates to the technical field of waste water treatment, in particular to a waste water recycling device and a use method. Background technique [0002] With the rapid development of industrial production, industrial drainage has gradually increased, which has exacerbated the shortage of pool water resources. In chemical production, tap water is often used to clean packaging barrels and their reactors for cooling. At the same time, ground cleaning also requires a lot of water. These The waste water after use will contain a large amount of sediment and chemical raw materials, which will cause great pollution to the environment. The production process of chemical products needs to discharge a large amount of chemical wastewater, and the composition of chemical wastewater is complex, the water volume changes greatly, the pollutants in the wastewater are high, and there are many toxic and harmful substances. If only chemical methods are used ...
