Title: Innovations by Wencong Rong in Chromium Recycling

Introduction

Wencong Rong is a notable inventor based in Guangdong, China. He has made significant contributions to the field of environmental technology, particularly in the recycling of chromium from hazardous materials. With a total of 2 patents, his work focuses on innovative methods for detoxifying and recycling chromium-containing residues.

Latest Patents

Wencong Rong's latest patents include a detoxification treatment method for extracting and recycling chromium from hexavalent chromium-containing residues. This method involves several steps, starting with the addition of water to the residues and mixing uniformly. Following this, sodium sulfate, sodium chlorate, and sulfuric acid are added to create a mixed liquid. The mixed liquid is then treated using a hydrothermal method or direct heating. After cooling, the solid-liquid mixture is separated, and the solid residues are washed and dried. The chromium-containing supernatant is precipitated using CaCl2, allowing for the recycling of chromium solutions.

Another significant patent by Rong is a treatment method for resource recycling of hexavalent chromium-containing residues. This method also begins with the addition of water to the residues, followed by the incorporation of mineralizers such as sodium chlorate, sodium perchlorate, and hydrochloric acid. Similar to his first patent, the mixed liquid undergoes hydrothermal treatment or direct heating, followed by cooling and separation of solid residues and chromium-containing supernatant.
