Abstract

The utility model discloses a porous and multicavity concave-convex type modified filter medium. The porous andmulticavity concave-convex type modified filter medium is made into a spherical body or a square body by china clay or porcelain clay; the spherical body or the square body is provided with through holes (2) which are mutually separated or communicated; the surface of the spherical body or the square body is provided with a convex body (3), a concave body (4) and a slot (5) which are mutually separated to cause the spherical body or the square body to form a reticular body; the interior of the reticular body has a plurality of cavities, and the surface of the reticular body is convex-concave; thus, the porous and multicavity concave-convex type modified filter medium has a large specific surface area; the porous and multicavity concave-convex type modified filter medium can form a crossed turbulent state during biological treatment, can improve the film hanging speed of a filter medium, can change the hydraulic condition of the filter medium, can improve biological treatment effect and can lower the cost of the biological treatment.

Description

A kind of porous multi-cavity convex-concave modified filter material

Technical field

The utility model relates to a kind of biological treatment filtrate, especially a kind of biofilm speed height, the porous multi-cavity convex-concave modified filter material that hydraulics is good.

Background technology

At present, when in BAF, carrying out a biological disposal upon, gac commonly used, spherical haydite, porcelain sand etc. are carried out a biological disposal upon as the biofilm carrier of biology, and these filling intensities are lower, and it is high that filler is piled up, the back flushing vector is big, the biofilm of intersecting in the water is left alone without help stays the time short, uses in the existing market, does not satisfy the needs that filtrate uses in BAF, thereby the biological treatment cost is higher, and treatment effect is not so good.

Technology contents

At above-mentioned existence with gac, spherical haydite, porcelain sand as the filtrate production cost height of carrying out a biological disposal upon, the problem that treatment effect is not so good, the utility model provide a kind of intensity height, and hydraulics is good, the biological treatment cost is low, the porous multi-cavity convex-concave modified filter material that treatment effect is good.

The utility model purpose is achieved in that it makes a kind of modified filter material by price low potter's clay or china clay, and described modified filter material can be formed by single filtrate body, its this body profile of filtrate body spherical in shape or square body; Described modified filter material also can be the plum blossom shape by a plurality of spheroplast filtrate bodies and be interconnected to form, spheroplast or square body are provided with apart or continuous through hole, spheroplast or square body surface are provided with apart convex body or concave volume, and spheroplast or square body surface are provided with groove.

Spheroplast described in the utility model can be a solid, also hollow body; Described through hole is a circular hole, also can be square hole; Described convex body or concave volume are the hemisphere bodily form, also can be the cylinder bodily form or the square bodily form.

The utility model is because its spheroplast or square body are provided with apart or continuous through hole, be provided with apart convex body or concave volume in its surface, be provided with groove in its surface, make it form inner multi-cavity, surperficial convexo-concave reticulate body, thereby have very big specific surface area, when biological treatment, can form the intersection turbulent state, can improve the biofilm speed of filtrate, change the hydraulics of filtrate body, improved biological treatment effect, reduced the biological treatment cost.
