Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] refer to figure 1 , is a detection and recovery device for concrete wastewater disclosed by the present invention, comprising a sedimentation tank 1, an acidification tank 2, a detection tank 3 and a recovery tank 4 connected in sequence. The bottom of the sedimentation tank 1 is provided with a funnel 15, the bottom of the funnel 15 is provided with a discharge port 16, the discharge port 16 is provided with a pneumatic discharge valve 17, and the inner ring of the discharge port 16 is provided with a sealing ring. A sand-stone separator 23 is arranged below the discharge port 16 , and the discharge port 16 communicates with the inlet of the sand-stone separator 23 . The settling tank 1 is embedded and slidably connected with a filter plate 18, and a plurality of small holes are penetrated on the filter plate 18 to prevent sand and gravel from passin...

Abstract

The invention relates to a concrete wastewater detection device. The device comprises a sedimentation tank, an acidification tank, a detection tank and a recovery tank which are sequentially communicated. A dosing device is arranged on the acidification pool. A PH value sensor is arranged in the detection pool. A first connecting pipe and a second connecting pipe are communicated between the acidification pool and the detection pool from top to bottom, the first connecting pipe is provided with a first one-way valve for enabling water to flow from the acidification pool to the detection pool in a one-way mode, and the second connecting pipe is provided with a second one-way valve for enabling water to flow from the detection pool to the acidification pool in a one-way mode. The acidification pool and the detection pool are designed as different pools, so that the influence of residual acidic chemicals in the acidification pool on the PH value of the acidified wastewater is reduced, finally, the qualified wastewater is discharged into the recovery pool for storage so as to be conveniently used for dust falling of a concrete mixing plant and used as general domestic water, and the effect of conveniently increasing ways of wastewater use after the wastewater is detected to reach the standard is achieved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a detection and recovery device and method for concrete wastewater. Background technique [0002] At present, with the continuous acceleration of my country's urbanization process, the concrete industry has been booming. 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 th...
