Pulp and Paper Waste Management System

The centrifuge system of BZ pulp and paper wastewater treatment can effectively solve the problem of pulping and paper making wastewater treatment in the industrial production of paper making factory. It is a simple, economical and efficient treatment equipment. Small floor area, high wear resistance and low energy consumption, easy maintenance, is the ideal treatment equipment.

Description

Pulp and Paper Making Wastewater mainly comes from pulping and paper making processes in paper making industry.

1. Pulping is the plant raw materials in the fiber separation, into pulp, bleach pulp;

2. Paper is the pulp dilution, molding, pressing, drying, copying, processing into paper.

Pulp and Paper Making Wastewater Produce Source and Processing:

Pulping and paper are discharging a lot of wastewater. The wastewater produced by pulping is the most polluted. When the slurry is washed, the effluent is black brown, known as black water. The concentration of pollutants in black water is very high, BOD is as high as 5-40g/L, and contains a lot of fiber, inorganic salt and pigment. The wastewater from bleaching process also contains a lot of acid and alkali substances. The wastewater discharged by the paper making machine is called white water, which contains a large number of fibers and fillers and adhesives added in the production process.

Paper making factory wastewater mainly contains the suspended material such as cellulose, lignin, lignin and cellulose can biological sex is very low, all can hardly degradable in the conventional biochemical treatment, and paper mill wastewater lignin and cellulose suspension after entering biochemical reactor, the influence on biochemical reactor operation, and in the biochemical reactor, a large number of suspended matter will exclude biochemical reactor sludge layer in the sludge, the sludge layer of sludge are almost no biological activity of lignin, cellulose, serious influence biochemical reactor running effect, serious when even make the system collapse, after cannot complete its proper function.

So that need before the biochemical treatment must first remove most of the suspended solids, to ensure the smooth progress of the follow-up processing, at present the method of removal of suspended solids fine machine, grille, filtration, precipitation, air flotation, etc., used here is more convenient and effective method, using the horizontal screw centrifuge of paper mill wastewater treatment, for the following reasons:
1. Paper making wastewater contains surfactant. If activated sludge process is used to treat it, a lot of foam will be produced on the surface of the water, which will seriously interfere with the production;
2. Aerobic biochemical method has the following advantages: high volume load and short treatment time; High biological activity, biological diversity, good mass transfer effect; High biological concentration, low sludge yield, no back flow; The water output is stable and the power consumption is relatively low. The film hanging is more convenient and the time is shorter. No sludge bulking problem.

Pulp and Paper Wastewater Treatment Equipment Decanter Centrifuge System Product Features:

1. A variety of models and capacity of centrifuges to choose from

2. It uses less water for cleaning centrifuge and consumes less energy

3. Less wearing parts, easy to maintain daily

4. Compared with other processing equipment, the BZ centrifuge occupies a small area

The centrifuge system of BZ pulp and paper wastewater treatment can effectively solve the problem of pulping and paper making wastewater treatment in the industrial production of paper making factory. It is a simple, economical and efficient treatment equipment. Small floor area, high wear resistance and low energy consumption, easy maintenance, is the ideal treatment equipment.
