Embodiment 1
[0053] An engineering mud treatment system, the mud treatment system comprising:
[0054] In the embodiment, the filter press used is a quick-opening diaphragm filter press, model KMZGF600 / 2000-U.
[0055] Pretreatment unit A, adjustment unit B, conditioning modification unit C, filter press dehydration unit D and residual water treatment unit E;
[0056] After the mud passes through the pretreatment tank, the impurities in the mud are removed;
[0057] The pretreatment unit A includes: a pretreatment pool A1, a rotary grille A2, a debris conveyor belt A3 and a debris recovery device A4, the pretreatment pool A1 is provided with a mud inlet A101; the pretreatment pool A1 is divided into Pretreatment pool water distribution area A102, heavy object settlement area A103 and light impurity removal area A104. The pretreatment pool water distribution area A102 is triangular and gradually expands along the direction of the heavy object settlement area A103. The mud inlet A101 It is...
Embodiment 2
[0082] Use the system of Embodiment 1 to process engineering mud.
[0083] This treatment method is applied to the construction mud treatment plant in Yinzhou District, Ningbo City, and the designed construction mud treatment capacity is 3600m 3 / d, with a total area of 13,500㎡. Due to certain restrictions on the amount of mud entering the site, the average daily processing capacity in actual operation is about 3,000m 3 / d; The output mud cake is used as raw material for the production of green planting soil, and the remaining water is discharged after treatment and reused for plant greening and dust reduction.
[0084] The treated mud is mainly the construction mud produced by piling in Ningbo City, which is transported to the factory through sealed tank trucks. The moisture content of the mud varies greatly, generally between 70% and 90%. The amount of mud entering the factory at different times of day and day by day Fluctuates violently and is greatly affected by seasons...
Embodiment 3
[0117] Use the system of Embodiment 1 to process engineering mud.
[0118] This treatment process is applied to Binhai Construction Mud Treatment Plant in Keqiao District, Shaoxing City, with a designed construction mud treatment capacity of 7200m 3 / d, with a total area of 33,000㎡, the actual average daily processing capacity is about 6,600m 3 / d; The output mud cake is used as project backfill, and the remaining water is treated and reused for plant greening, dust reduction and other purposes, and the remaining part is discharged up to the standard.
[0119] The treated mud is the construction mud produced by piling in Keqiao District, Shaoxing City, which is transported to the factory by mud ships and sealed tank trucks. The moisture content of the mud is generally between 70% and 90%.
[0120] Step S1: The engineering mud enters from the pretreatment tank, removes sundries such as sedimentary sand and construction waste; every 2 days, the sundries cleaned out are mainly...
