Palm root carbon preparing process and its biomembrane reaction apparatus

Abstract

The invention provides a palm root charcoal preparing process and a biomembrane reactor prepared by the palm root charcoal. And the preparing process comprises cutting into blocks, charring and screening, crushing and screening the palm roots and obtaining 1.0-1.5 cm-sized rough grains; and in the absence of air, heating and carbonizing the rough grains and degasifying, where the carbonizing temperature is 360-390DEG C and the carbonizing time is 1.5-2 h. And the biomembrane reactor comprises palm root charcoal biofiltering tank, water distributing pipe and gas distributor, where the water distributing pipe and gas distributor are arranged in the biofiltering tank, the biofiltering tank is filled with palm root charcoal, the bottom of the biofiltering tank is equipped with recoil gas pipe interconnected between water inlet and outlet pipes. And the prepared palm root charcoal has characters of large specific surface area and high mechanical intensity. And it adopts palm root charcoal to form the biomembrane, having high organic pollutant degrading speed and good sewage purifying effect.

Description

technical field [0001] The invention relates to a particle filler and a biofilm reaction device in sewage purification treatment equipment, and belongs to the technical field of a particle filler preparation process and a biofilm reaction device. Background technique [0002] Palm originates in the south of China and is widely distributed in my country. Palm tree roots are often treated by burning. Since palm tree roots are not easy to burn, this method not only pollutes the environment, but also wastes resources. Palm root is different from other plant roots. After carbonization, its exterior is microporous, and its interior is cellulose structure. It has the characteristics of large specific surface area and high mechanical strength. Strengthening the research and development of brown root charcoal utilization technology and accelerating its industrialization process will not only turn waste into useful resources, but also will promote the treatment of sewage in our countr...

AI Technical Summary

Problems solved by technology

The granular fillers commonly used in water treatment are mainly ceramsite or activated carbon; most of ceramsite has the disadvantages of high energy consumption, poor film-hanging performance, and is not conducive to the growth and reproduction of microorganisms, while activated carbon also has low mechanical strength, complicated process, Disadvantages such as poor economic benefits

[0004] At present, there is no report on the use of palm as a particle filler, and there is no report on the preparation process of palm root charcoal
