Embodiment Construction

[0028] see figure 1 , is a flow chart of the manufacturing method of the present invention. After mixing thermoplastic materials with biodegradable organic materials, extrusion processing can be used to produce filter materials for water treatment with rough surfaces, which is conducive to the attachment of microorganisms in water.

[0029] The filter material for water treatment of the present invention can be made into different shapes according to requirements, and is not limited by the processing method. The filter material has a rough surface due to physical phenomena such as different specific gravity and flow coefficient between biodegradable organic materials and thermoplastics; biodegradable organic materials can account for 5% to 30%. The thermoplastic can be PP, PE, ABS, etc., and the biodegradable organic material can be cornstarch, rice husk powder, wood flour, etc. The hot pressing conditions are as follows:

[0030] When the thermoplastic is PP, the melting t...

Abstract

The present invention relates to a method for making filtering material for treating water and its products. The making method includes the following steps: firstly, mixing thermoplastic material with bio-degradable organic material, making them undergo the process of thermocompression forming or ejection forming treatment so as to obtain the invented water-treating filtering material with rough surface. Said invention can make various products with large specific surface area and large porosity, specially, said filtering material can be made into porous plate material, pipe material and film products with various forms.

Description

【Technical field】 [0001] The invention relates to a manufacturing method of a water treatment filter material with a rough surface and its products. 【Background technique】 [0002] For example, the patent case of "biological filter material structure" in Taiwan Patent Publication No. 291696, the biological filter material can be used for water treatment and filtration, but the filter material is usually made of mechanical means to make the surface of the material adhere to microorganisms. Rough surface, products made of rough surface by mechanical means, due to the limitation of mechanical draft angle and strength factors, can only be made into products with simple structure, small surface area and small porosity, or secondary processing and other methods are required In order to make products with large surface area and large porosity. [0003] Therefore, the manufacturing method adopted by the known biological filter materials for water treatment to make the surface rough...
