Abstract

The invention relates to waste water or sewage treatment by using vegetable stalks as decontamination material, wherein the process for preparing the material comprises, subjecting the vegetable stalks to rolling, cutting into chunks, shred expelling, curing or drying, or rolling, disintegrating the vegetable stalks into 20-200 mesh particles, squeezing into particles with diameter being 3-4.5 mm by using starch as binding agent. The invention also discloses the process for treating sewage water by using the vegetable stalks.

Description

technical field [0001] The present invention relates to the treatment of water, waste water, sewage or mud. Background technique [0002] Red tide pollution in coastal waters; frequent occurrence of algal blooms in rivers and lakes; oil spills; sewage discharge from industrial production, etc., have not only caused huge direct damage to the growth of the national economy, but also threatened sustainable development. In order to improve the deteriorating water environment and to deal with major water pollution emergencies in a timely and effective manner, a large number of sewage interception, sewage discharge and sewage treatment plant projects have been built. In recent years, through the efforts of environmental protection scientists, a number of new scientific research results have been obtained. For example, the successful development of oil-condensing agent can timely and effectively deal with the serious pollution caused by oil tanker leakage; the application of the r...
