Embodiment 1
[0068] figure 1 It is a schematic diagram of the structure of the present invention, such as figure 1 The shown automatic dewatering system for seawater pretreatment sludge includes a sedimentation tank 1, a maturation tank 2, a sand injection tank 3 and a coagulation tank 4. The maturation tank 2 is connected to one side of the sedimentation tank 1, and the sand injection tank 3 is connected. On one side of the maturation tank 2, the coagulation tank 4 is connected to one side of the sand injection tank 3, and the sedimentation tank 1, the maturation tank 2, the sand injection tank 3 and the coagulation tank 4 are connected to each other. The circulation mode realizes the efficient mixing and multi-stage sedimentation mode of extending the seawater flow channel. Coagulation aid) is mixed evenly and then conducts a coagulation and sedimentation; the sand injection tank 3 is used as a high-efficiency coagulation and sedimentation tank for seawater pretreatment. Treatment of h...

The invention relates to the technical field of seawater desalination, in particular to an automatic dehydration system and method for seawater pretreatment sludge, the system comprises a sedimentation tank, a curing tank, a sand injection tank and a coagulation tank, the curing tank is connected to one side of the sedimentation tank, the sand injection tank is connected to one side of the curing tank, and the coagulation tank is connected to one side of the sand injection tank; the sedimentation tank, the curing tank, the sand injection tank and the coagulation tank are communicated with one another; a plurality of inclined pipes which are obliquely arranged at an angle of 45-60 degrees are arranged in the sedimentation tank; and a clarified seawater collecting tank is arranged at the upper ends of the inclined pipes. The problems that a traditional seawater pretreatment process is large in occupied space, single in system arrangement, short in cycle operation, poor in water quality index, high in maintenance cost in the sludge cleaning and transporting process, long in operation cycle, small in limited space, large in airing occupied space, large in safety risk and many uncontrollable factors, not ideal in comprehensive effect and the like are effectively solved. And safe and stable water feeding operation of the seawater desalination system is ensured.
Description
technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a seawater pretreatment sludge automatic dewatering system and a method thereof. Background technique [0002] At present, the commonly used seawater desalination processes in the world are mainly concentrated in two forms: thermal method and membrane method. For different seawater desalination treatment processes, the corresponding pretreatment technologies have different goals. In seawater desalination processes such as multi-stage flash evaporation and low-temperature multi-effect evaporation, in order to ensure the stable operation output requirements of the seawater desalination plant and meet different process technology and water quality requirements, the seawater pretreatment process must be carried out. [0003] The purpose of seawater pretreatment is to remove impurities such as particles, mud sand, colloids and microorganisms in surface seawater. When sea...
