Embodiment Construction

[0014] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail:

[0015] As shown in the figure, the sewage treatment device of the factory, the wastewater pool 1, the wastewater treatment device, the dosing device 11 and the sump 9, and the sewage from each workshop are imported into the wastewater pool 1 through pipelines. The waste water tank 1 is connected to the input end of the waste water treatment device, and the waste water treatment device includes a regulating tank 2 , a reaction tank 3 , an air flotation tank 4 , a water distribution tank 5 and an anaerobic tower 7 connected in series. The pool body of the regulating tank is divided into a water inlet chamber and an aeration chamber through a partition, the water inlet chamber is connected with the waste water pool, the aeration device 21 is arranged in the aeration chamber, and the aeration chamber is connected to the reaction tank 3 through a ...

Abstract

The invention provides factory sewage treatment device capable of realizing complete treatment. The sewage treatment device regulates sewage and then sends the regulated sewage into a reaction tank for reaction; the particulate matters are accelerated in a floatation tank to form bubbles, and the bubbles are fed into a scum tank through a scum scraper. Foam in the scum tank is sent into a spiral sludge dewatering machine for solid-liquid separation, liquid flows back to an adjusting tank for subsequent treatment and circulation, sewage treated by the floatation tank is sent into an anaerobic tower for treatment after being treated again in a water distribution tank and finally discharged into a water collecting tank, the sewage is completely processed in the system, and environmental pollution caused by the sewage is effectively reduced.

Description

technical field [0001] The invention relates to the field of factory wastewater treatment, in particular to a factory wastewater treatment device. Background technique [0002] Chemical production usually produces a variety of sewage with chemical substances, including alkaline, acidic and neutral sewage. Sewage needs to be treated before it can be discharged. The sewage treatment in the prior art usually mixes the acidic sewage and the alkaline sewage and then neutralizes it, then treats the neutralized sewage with microorganisms and aeration, and finally discharges the sewage after sedimentation. The sedimentation speed in this treatment method is too slow, and the flocculant is added in time and cannot be completely and fully precipitated, and the treatment is not sufficient. Contents of the invention [0003] The purpose of the present invention is to provide a completely treated factory sewage treatment equipment. [0004] The technical scheme that the present inve...
