Embodiment Construction

[0034] Such as figure 1 Shown, a kind of comprehensive purification method that contains heavy metal ion and organic waste water, comprises the steps:

[0035] (1) Measure and record in detail the chemical indicators, pollutant components, daily discharge, physical indicators and geographical location of muddy sewage discharged by each enterprise or each workshop in the enterprise.

[0036] (2) According to the measured data, choose a reasonable location to establish a comprehensive purification muddy sewage treatment site. A reasonable address can be selected by the optimization method to save construction costs.

[0037] (3) Classified collection of muddy sewage, build several waste water recycling pools 1, homogeneous pool 2, emergency pool 5, dosing pool 3, buffer pool 6 and neutralization pool 4 in muddy sewage treatment sites according to needs , classify and collect the muddy sewage generated into several waste water recycling tanks.

[0038](4) Utilizing the differe...

Abstract

The invention belongs to a method and a device for comprehensively purifying wastewater containing heavy metal ions and organics. The method comprises the following steps: blending and mixing different types of mud-containing sewage in a homogenization tank according to different chemical indexes and measured data of the mud-containing sewage in all wastewater recycle pools, so that the chemical indexes of the mud-containing sewage are changed, the water amount is uniform and floccules are formed, or pollutants in the water are precipitated. A mechanical purifying device comprises a base, a mud sewage magnetization tank, an electrolyzing and magnetizing machine, a medicine blending, flocculating and feeding tank and a mud-water separator. The method and the device disclosed by the invention can be used for comprehensively purifying industrial wastewater containing pollutants such as heavy metal ions, suspended solids and organics, and has the advantages that purifying equipment construction cost is low, the treatment cost is low and good energy conservation and environmental pollution effect and good purification effect are achieved.

Description

technical field [0001] The invention belongs to a method for purifying industrial waste water containing heavy metal ions, suspended solids, organic matter and other pollutants and a device used therein. Background technique [0002] Industrial wastewater (or muddy sewage) containing heavy metal ions, suspended solids, organic matter and other pollutants is one of the key pollution sources in my country's industrial system. These muddy sewage mainly come from mechanical processing, mining, textile printing and dyeing industries and The extraction and purification of various metal elements, the large amount of muddy sewage discharge, the concentration of various metal ions in the water, the concentration of suspended solids and the concentration of organic matter, etc., all greatly exceed the harmless discharge standards stipulated by the state. The discharge of these muddy sewage will cause serious pollution to the natural environment and endanger the living environment of or...
