Problems solved by technology

However, many existing concrete mixing plants do not carry out effective detection of waste water and blindly recycle it, resulting in defective concrete produced by recycling waste water

Embodiment Construction

[0028] The technical solutions of the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0029] Such as figure 1 Shown, a kind of detection technology of concrete waste water, comprises the following steps:

[0030] Step 1. Wastewater collection: Collect rainwater from the concrete mixing plant, wastewater from site washing, wastewater from sand separators, wastewater from spraying facilities, and domestic water through water pipes arranged on the ground of the site;

[0031] Step two, five-stage sedimentation: the collected wastewater is passed into the first-stage sedimentation tank for sedimentation, and then the wastewater impurities are precipitated in sequence through the second sedimentation tank, the third sedimentation tank, the fourth sedimentation tank and the fifth sedimentation tank, and finally Discharged into the cesspool for storage as sewage;

Abstract

The invention relates to a concrete wastewater detection process and belongs to the technical field of concrete detection processes. The concrete wastewater detection process comprises the following steps of (1) wastewater collection: collecting concrete mixing plant wastewater through a water pipe arranged on the ground of a site, (2) five-stage precipitation: sequentially introducing the collected wastewater into five precipitation tanks for wastewater impurity precipitation and finally discharging the wastewater into a sewage tank for storage to obtain sewage, (3) solid content, pH value and color detection of the sewage, wherein the solid content of the sewage is measured through a mud hydrometer measuring method, the solid content is not larger than 8%, the pH value is directly measured through an acidometer, the pH value ranges from 6 to 8, the color of the sewage is observed through naked eyes, and the sewage is colorless, and (4) proportioning sewage concentration, wherein thetotal concentration does not exceed 5%. The concrete wastewater detection process has the advantage that the content of the wastewater is effectively and quickly detected before the wastewater is recycled so that the wastewater meets a recycling requirement.

Description

technical field [0001] The invention relates to the technical field of concrete detection technology, in particular to a detection technology of concrete wastewater. Background technique [0002] In recent years, with the continuous acceleration of my country's urbanization process, the concrete industry has developed vigorously. During the production of concrete, a large amount of waste water and waste residue will be generated. For each cubic meter of concrete produced, 0.17 tons of clean water will be consumed, and the average production of waste water and waste slurry will be 0.03 tons. my country's annual concrete output exceeds 1.5 billion cubic meters. According to this calculation, my country's annual waste water and slurry production is as high as 50 million tons. Concrete enterprises must deal with the waste water and waste residue produced by the mixing plant, realize green production, truly realize the goal of zero discharge of waste water and waste residue in t...
