Process for reclaiming lead and producing environment-friendly building material by waste flint glass and corollary equipment thereof

Abstract

The invention establishes a vacuum carbon thermal reduction process applied in high added value and resource recycling of waste flint glass, and optimizes corollary equipment, direct to the current situations of serious environment pollution and resource recycling technology of the waste flint glass. The process has the characteristic that while reclaiming lead in the waste flint glass, the rest glass residue is formed into a good-quality environment-friendly building material through controlling conditions. Results of toxicity extraction experiments prove that extraction amount of lead and other heavy metals in a product is lower than the reference value of national regulation, and can be used as a light environment-friendly building material.

Description

technical field

[0001] The invention relates to resource utilization and pollution control technology of waste lead-containing glass, belongs to the technical field of environmental protection and resource comprehensive utilization, and is especially suitable for resource utilization of lead-containing hazardous solid waste. Background technique

[0002] The hazards of lead have attracted widespread attention over the years. Japan and western countries have enacted a series of relevant laws to limit the use and discharge of lead. Lead can accumulate in the body and cause lead poisoning. The effect of lead poisoning is quite slow and the toxicity is hidden, and it is not easy to be detected before the toxicity appears. my country has promulgated discharge standards for lead-containing sewage in nonferrous metals, petroleum, textile, sulfuric acid and other industries. With the continuous development of technology, lead standards for household products are also being continu...
