Stone material cutting sewage coarse sand precipitation sand discharging system

Abstract

The invention discloses a stone material cutting sewage coarse sand precipitation sand discharging system, which comprises a coarse sand precipitation pool with the big upper end and the small lower end, wherein a sewage dressing device is arranged in a position of a water inlet of the coarse sand precipitation pool; a spiral coarse sand conveying device used for conveying precipitation coarse sand to a position outside the coarse sand precipitation pool is arranged at the bottom of the coarse sand precipitation pool; a sand blocking flow separation plate is arranged in the coarse sand precipitation pool; a fine sand sewage outlet chamber is formed between the sand blocking flow separation plate and the pool wall of the coarse sand precipitation pool; a fine sand sewage conveying device is arranged in a position outside the fine sand sewage outlet chamber. The system can realize the grading recovery and utilization of ore powder (iron powder) and coarse sand in the sewage; the environment pollution is avoided; the resource treatment of the stone material cutting sewage is facilitated.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to a coarse sand sedimentation system for stone cutting sewage. Background technique [0002] Stone cutting sewage treatment has always been the focus of environmental protection concerns of various production enterprises and governments, and a complete set of stone cutting sewage comprehensive treatment equipment has gradually appeared on the market. However, due to the large cost and high operating costs of the existing comprehensive treatment equipment, some enterprises do not have such comprehensive sewage treatment equipment, but use various methods to settle the stone cutting sewage, and the waste water and sawing silt cannot be recycled. Utilization will pollute the environment more; and the processed sand is the best purified water resource in the river. Over the years, many river courses have lost sand, which has caused great harm to the environment. Al...
