Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The fully mixed bio-augmented hydrolysis tank includes a tank body, a specialized engineering bacteria dosing device, an immobilized biofilm device, a swirling aeration device, and a bacterial circulation return device. The upper end of the tank body is open, the lower left end of the tank body is provided with an inlet, the inlet is used to input the waste water from the previous step into the tank body; the upper right end of the tank body is provided with a water outlet, and the water outlet is used to output the treated waste water. The inlet is connected with the tank through the pipeline mixer. One side of the tank body is provided with an immobilized biofilm device; the specific engineering bacteria dosing device is arranged above the tank body to add specific engineering bacteria into the tank body. The other side of the tank body is provided ...

Abstract

The invention relates to a completely mixed bio-enhanced hydrolysis tank, which includes a tank body, a special engineering bacteria adding device, an immobilized biofilm device, a swirl aeration device and a bacteria circulation reflux device; an inlet is arranged at the lower end of one side of the tank body. The inlet is connected with the tank body through a pipe mixer. The upper end of the other side of the tank body is provided with an outlet and the lower end is provided with a mud discharge port. The biofilm immobilized device is arranged on one side of the tank body, and the special engineering bacteria adding device is arranged on the top of the tank body. The other side of the tank body is provided with the bacteria body circulation reflux device. The swirl aeration device is arranged in the lower part of the tank body. A carbon-free carbon paper coating wastewater treatment method uses the completely carbon-free carbon paper coating wastewater treatment system. The tank hasthe advantages of high removal rate of COD and organic matters, good purification effect and convenient treatment and the like. The invention belongs to the technical field of industrial sewage treatment.

Description

technical field [0001] The invention belongs to the technical field of industrial sewage treatment, and in particular relates to a fully mixed bio-intensified hydrolysis tank, a carbonless copy paper coating wastewater treatment system and a carbonless copy paper coating wastewater treatment method. Background technique [0002] Carbonless copy paper is a kind of coated processed paper, and the coating of carbonless copy paper is an important part of carbonless copy paper. Carbonless copy paper includes bottom sheet, top sheet, and middle sheet. Bottom paper: The paper is only coated with color-developing layer coating, also known as surface coated paper (CF: Coated Front), and its coating method is the same as that of ordinary coated paper. Upper page paper: The paper is only coated with microcapsule paint, also known as back-coated paper (CB: Coated Back), which is coated with microcapsules containing Limin pigment oil solution on the back of the paper. Middle page paper...
