Embodiment Construction

[0016] figure 1 It is a cylindrical structure filler of the present invention, which is composed of a composite wing plate 1, a fixed connection ring 2, a water-repellent foam plastic 3, and a middle fixed ring 4. Composite wing plate 1 is made of nylon wing plate 5, functional water treatment material 6 is made of powdered zeolite, activated carbon, diatomaceous earth, ceramsite, activated aluminum, and manganese sand, and is bonded by surface thermal bonding or surface adhesive Composite on the surface of wing plate 5. The wing plate 5 is fixedly connected with the fixed connection ring 2 and the middle fixed ring 3 through its outer side up and down and its inner side up and down. By sandwiching a certain amount of water-repellent foam plastics 4 between some composite wing plates 1, the specific gravity of the filler of the present invention is adjusted so that it is close to one, so that it can be fully fluidized for water treatment during aeration. .

Abstract

The present invention relates to one kind o water processing functional suspended stuffing and its preparation technology, and the functional suspended stuffing is suitable for treatment of various kinds of waste water. Winged plates for stuffing, fixed connecting ring and middle connecting ring are made with polar plastic and connected to form an integral, and powdered functional water processing material is covered onto the surface of the winged plates via hot binding or adhesion with surface adhesive to constitute composite winged plates. The present invention has convenient making, great surface area, high water processing capacity and convenient maintenance with less back flushing needed.

Description

technical field [0001] The invention relates to a functional suspended filler for water treatment and its production technology, which is suitable for the treatment of various waste water. Background technique [0002] The existing fillers for water treatment are basically made of plastics such as polyethylene, polystyrene, polypropylene, etc., as the carrier of microorganisms in biological treatment. Due to the hydrophobicity of these plastics, microorganisms are not easy to adhere to their surfaces. Usually, such fillers have no other functions except as a carrier for microorganisms to adhere to. In order to improve and improve the functionality of the filler, the invention patent application "A New Functional Suspended Filler" (CN 03115913.3) proposes to combine hydrophobic plastic fillers with materials with special water treatment functions such as: zeolite (molecular sieve) and activated carbon. Functional material particles are embedded an...
