Embodiment Construction

[0010] Stone and stone products are widely used today, and the stone processing industry is in constant development. During the cutting, polishing, and grinding processes of stone slabs, milky white wastewater containing suspended stone powder, oil, and other pollutants and dyes is produced. The disorderly discharge of wastewater has a wide range of environmental pollution, deep water pollution, and serious ecological damage.

[0011] Stone processing wastewater has high pollutant concentration, large quantity, and deep color, and it is difficult to treat due to the different particle sizes of suspended stone powder. Suspended substances with a particle size above 1000 μm can be quickly settled and separated without flocculant; suspended substances with a particle size of 600 to 1000 μm can be precipitated by adding different quantities and types of flocculants; suspended substances with a particle size of 200 to 600 μm can be precipitated by adding a certain amount Different ...

Abstract

The invention relates to the field of environment protection, in particular to a method for treating wastewater, more particularly to a technology for deeply treating stone processing wastewater. The technical effect of deeply treating the stone processing wastewater is achieved by adopting deep physicochemical treatment processes such as regulation, addition of an active flocculating agent, air floatation, beam current and sedimentation. The technology has the advantages of advanced process, high recycling efficiency of the treated water, good comprehensive utilization effect and low operation cost of the treating process, is beneficial to environment protection, energy saving, emission reduction and development of stone processing industry, and has remarkable environment benefit, social benefit and economic benefit.

Description

technical field [0001] The invention relates to the field of environmental protection, and relates to a wastewater treatment method, in particular to an advanced treatment technology for stone processing wastewater. Background technique [0002] During the cutting, polishing, grinding and other processes of stone slab processing, milky white wastewater containing suspended stone powder, oil pollution and other pollutants and impurities is produced. The disorderly discharge of wastewater has a wide range of environmental pollution, deep water pollution hazards, and serious ecological damage. [0003] Stone processing wastewater has high pollutant concentration, large quantity, and deep color. Due to the different particle sizes of suspended stone powder, it is difficult to treat it. In the traditional sewage treatment process, the commonly used flocculants are difficult to settle the small particle size suspended matter in the stone processing wastewater, and cannot achieve a...
