Embodiment 1

[0036] When the mud moisture content ω n ≥300%, according to formula C n =eC 3 ω n / ω 0 , to obtain the corresponding flocculant concentration at this time, e is a constant, which can be obtained through the flocculation test of known gradient mud moisture content, the value of e is 0.3 according to the small test test, C 3 is the corresponding flocculant concentration when the water content of the mud is 300%, and C is measured according to the small test 3 The value of 2‰, a certain known water content of mud ω 0 The value of is 200%; assuming that the mud water content at this time is 400%, the flocculant C n The concentration is C n =0.3×0.002×4÷2, C n =1.2‰. After the flocculant concentration is configured, it is sent to the mud delivery pipeline 3 . The flocculant delivery pipeline 4 is an anti-corrosion plastic pipeline with a diameter of 5 cm, and the pipeline at the mud delivery inlet of the material tank A is an S-shaped pipeline 5, where the mud and the flo...

Embodiment 2

[0039] When the mud moisture content ω n When ≤300%, the signal receiving processor 6 will transport the mud to the annular pipe 29, and at this time the switch 32 is closed, and the mud will be uniformly diluted in this pipe until the light transmittance is consistent with the light transmittance when the water content of the mud is 300%. , according to the small test, the transmittance T of mud moisture content 300% 1 =60%, assuming that the water content of the mud at this time is 200%, the corresponding light transmittance is T n , the transmittance of the diluted mud T 1 =T n =60%, now open switch 32, then mud enters mud delivery pipeline 3 by L shape mud delivery pipeline 31, C 3 The flocculant of =2‰ is delivered to the mud delivery pipeline 3 and mixed with the mud. The flocculant delivery pipeline 4 is an anti-corrosion plastic pipeline with a diameter of 5 cm, and the pipeline at the mud delivery inlet of the material tank A is an S-shaped pipeline 5, where the m...

Abstract

The invention discloses a waste slurry treatment system capable of continuously adjusting a flocculation scheme in real time and an implementation method thereof, wherein the system comprises a slurry pool, a slurry water content real-time detection system, an optimal flocculation scheme control system, a supernatant guiding and discharging system and an anti-clogging suction filtration mud scraping system; and the slurry pool is communicated with the slurry water content real-time detection system through a slurry conveying pipeline, the anti-clogging suction filtration mud scraping system is located in the supernatant guiding and discharging system, and the slurry water content real-time detection system, the optimal flocculation scheme control system and the supernatant guiding and discharging system are communicated through pipelines. The water content of the slurry can be tested in real time at the slurry water content monitoring device, and the optimal flocculation method is realized by diluting the slurry or adjusting the concentration of a flocculating agent.

Description

technical field [0001] The invention relates to a treatment device and method for waste engineering high water content mud, in particular to a waste mud treatment system and an implementation method for continuous real-time adjustment of flocculation schemes. Background technique [0002] At present, most of the treatment methods for high water content mud use belt filter press, plate and frame filter press, centrifuge, etc. for mud water separation and dehydration. These methods have working efficiency in treating high water content waste mud with high clay content. Low, can not work in batches and other defects. Most of the existing rapid mud dehydration and reduction methods are technical solutions of vacuum filtration, such as the Chinese invention patent publication "A Concentration System for Rapid Concentration of Mud" with the application number 201210317079.1. The pipeline realizes mud concentration through the combined action of gravity and negative pressure diffe...
