Recycled-water reusing combination pool and recycled-water reusing method

Abstract

A combination tank for reclaimed water designed in the present invention mainly includes reaction tanks, four of which are independent of each other and arranged in a rectangular array. A mud tank is arranged at the bottom of each reaction tank, and the four mud tanks pass through pipelines. Connected with the mud pump, there is a clear water pump and a submersible mixer in each reaction tank. The method of reclaimed water reuse is to inject the sewage in the fur production into the reaction tank, and add the medicament at the same time, use the submersible mixer to fully stir and settle for 20‑30 minutes, then pump out the clarified liquid in the reaction tank through the clean water pump, and repeat the cycle 10 times The sludge settled in the mud tank is pumped out by the mud pump. Such a reclaimed water reuse combination tank has a mud tank inside the reaction tank, and the reclaimed water is filled in the reaction tank, and the sediment produced by the chemical reaction will enter the mud tank, and the treated reclaimed water in the reaction tank will pass through Clean water pump out. After several cycles, the sludge is pumped out at one time by the mud pump, which can reduce the cost of use and improve efficiency.

Description

technical field [0001] The invention relates to the fields of wastewater treatment and reclaimed water reuse in the fur industry, in particular to a reclaimed water reuse combination pool and a reclaimed water reuse method. Background technique [0002] At present, the treatment of reclaimed water in the fur industry is only treated as sewage and then discharged. In this way, the temperature of reclaimed water needs to be cooled and the harmful substances in it must be separated before the reclaimed water can be discharged into rivers. This not only requires a large amount of cost to treat the reclaimed water, but also wastes a large amount of energy in the reclaimed water. In addition, the existing facilities for reclaiming reclaimed water are limited. Generally, reclaimed water is only put into one pool, and chemicals are added to precipitate harmful substances. However, the precipitation of harmful substances in the pool will be difficult to clean up, requiring a lot of m...

This not only requires a lot of cost to treat the reclaimed water, but also wastes a lot of energy in the reclaimed water

In addition, the existing facilities for reclaiming reclaimed water are limited. Generally, reclaimed water is only put into one pool, and chemicals are added to precipitate harmful substances. However, it will be difficult to clean up the sedimentation of harmful substances in the pool, requiring a lot of manpower.
