Description

Multifunctional efficient filter

Technical Field

The utility model relates to a filtration processing technique, concretely relates to multi-functional high-efficient filter.

Background

At present, sludge concentration is an effective method for reducing the water content and the volume of sludge. Sludge concentration is mainly used for reducing interstitial water of sludge. The concentrated sludge is paste-like, and can retain fluidity, and can reduce water content of sludge discharged from water treatment structure, so that it is a sludge treatment method capable of reducing its volume, and is applicable to sludge with high water content, for example active sludge, and its water content is up to about 99%. When the water content of the sludge is reduced from 99% to 96%, the volume of the sludge can be reduced to 1/4. In order to further treat the sludge efficiently and economically, concentration must first be carried out. The water content of the concentrated sludge is generally 95-97%. In the process of sludge concentration, the discharged sludge water contains a large amount of organic substances, and the organic substances are generally mixed with the original sewage for treatment without direct discharge so as to avoid polluting the environment. The tradition carries out the concentrated processing to mud, often adopts the civil engineering sludge thickening pond method that has vertical current formula or radial flow formula shape, uses high-order concentrated jar, but this type of treatment all has a large amount of problems:

1. large floor area, high operation cost and high civil construction cost. In view of the complex installation and maintenance, the maintenance time is long, the failure rate is high, and the maintenance cost is high.

2. The effect is influenced by the retention time of the sewage. For example, the too short sewage retention time can cause the concentration of supernatant to be too high, the concentration of sludge to be too low, and the required concentration effect cannot be achieved; if the retention time is prolonged, anaerobic decomposition or denitrification can be carried out, sludge is directly floated, and the concentration can not be carried out smoothly.

3. The concentration effect is influenced by climate. For example, the effect of temperature on the concentration effect is reflected in two opposite aspects: when the temperature is increased, on one hand, sewage is easy to hydrolyze and acidify (putrefy), so that the concentration effect is reduced; on the other hand, the increase in temperature lowers the viscosity of the sludge, and makes it easy to separate interstitial water from the particles, thereby improving the thickening effect.

4. The sludge concentration condition can not be directly observed, and the working state is not convenient to adjust at any time.

5. The safety factor is low, the common pool/pot is deep, and people, animals and sundries are easy to fall into the pool/pot and are damaged.

On the other hand, the paper industry wastewater contains not only harmful chemical inorganic substances but also organic substances such as volatile phenols, precipitated solids, suspended substances, and cellulose, which are necessary raw materials in the paper making process, and thus cellulose needs to be recycled. At present, a flocculation precipitation tower method is generally adopted, and a sedimentation method is utilized to separate out fibers so as to achieve the purposes of recovering the fibers and clarifying white water. The settling tower is a more existing settling device, white water enters the inner cover body of the settling tower from the top of the tower, and the inner cover body and the shunt tubes are used for enabling the white water to form a rotational flow body with certain strength and form a stable centrifugal settling form to sink. When the concentration of the white water is higher, the white water can continue to precipitate in the cone part of the tower, and at the moment, the concentration of the tail pulp in the cone part of the tower forms a stable concentration gradient according to the height of the cone under the action of downward flow distribution formed by the tail pulp continuously discharged from the bottom of the cone of the tower and gradually accelerates to enter the precipitation speed of the concentrated white water in the cone part. Most of the primarily precipitated precipitation water bypasses the edge of the inner cover body, so that the tower body awakening part continues to precipitate at a slow upward movement speed until the precipitation water enters the overflow groove through the overflow ring. As mentioned above, the separation method using the precipitation column method also has a number of problems:

1. the settleable performance of the fiber in water is utilized, the fiber can be settled only by the residence time, so that the settling tower generally occupies huge area.

2. A certain amount of fibers still exist in the effluent, and the filtering and separating effect is not good.

3. The installation and maintenance are complex, the maintenance time is long, and the maintenance cost is relatively high.

4. The civil engineering construction cost is high.

5. The effect is influenced by the retention time of the white water, for example, the retention time of the white water is too short, so that the concentration of the supernatant fiber liquor is high, the concentration of the discharged fibers is too low, and the fiber recovery effect is poor; the excessive retention time causes hydrolytic acidification, and the white water contains various dissolved organic matters, inorganic matters and the like, so that the particle size of the particles such as fibers is reduced, the specific gravity is reduced, and the sinking is difficult.

6. The fiber recovery effect is affected by weather, and for example, when the temperature is increased, the white water is easily hydrolyzed and acidified (rotten), so that the fiber recovery effect is reduced.

7. The process conditions of fiber recovery cannot be directly observed.

8. The safety factor is low, the common pool/tank is deep, and people, animals and sundries are easy to fall into the pool/tank and are damaged.

Through the above description, it is necessary to design a novel multifunctional high-efficiency filtering device for both sludge concentration and liquid filtration and fiber recovery and filtration separation.
