Embodiment Construction

[0008] see figure 1 The flow chart of the implementation steps of the present invention, by figure 1 It can be seen that the method for resourceful treatment of water purification tank sludge of the present invention comprises the steps of:

[0009] Sludge pumping: the bottom sludge is extracted from the clean water tank and pumped to the sludge sedimentation tank;

[0010] Sedimentation: The clarified water is drained in a multi-tank alternate manner, and then the sludge is introduced until the sedimentation tank is full of thick sludge;

[0011] Filtration: filter the sludge to remove impurities;

[0012] Stirring: Stir the sludge after filtering out impurities with a strong stirring pump and cause reflux, so that the sludge no longer settles;

[0013] Shotcrete granulation: The mud is pressurized by a high-pressure pump, sent to the granulation nozzle, and sprayed into the high-temperature sterilization drying tower. The hot air with high-speed heat flow in the tower is ...

Abstract

The invention relates to a method for the resource treatment of water plant clear water reservoir sludge. The method mainly comprises the following steps: depositing the water plant clear water reservoir sludge into slurry, removing sand-stone impurities by filtering, placing the slurry in a reflux stirring slurry tank for stirring, transferring the slurry to a high-temperature sterilization prill tower by a high-pressure pump, performing hot air sterilization drying on the slurry to obtain grain-shaped sludge grain, calcining the sludge grain, and stabilizing other materials in the grain-shaped sludge grain such as free aluminum ion and the like into artificial sand which is stabilized and pollution-free for resource reutilization.

Description

technical field [0001] The invention belongs to the technical field of recycling of environmental protection resources, in particular to a method for recycling sludge from a water purification pool. Background technique [0002] At present, coagulation technology is widely used in the water treatment of modern waterworks, that is, adding flocculants to quickly reduce the turbidity of raw water. Generally used flocculants such as polyferric sulfate, polysilicon aluminum sulfate (PASS), polysilicon aluminum chloride (PASC), polysilicon ferric chloride (PFSC), polysilicon ferric sulfate (PFSS), polysilicon aluminum ferric chloride (PAFSC), polysilicon aluminum ferric sulfate (PAFSS) and alum (Potassium alum), etc. Taking alum as an example, alum is the abbreviation of potassium alum, also known as alum or raw alum. Alum is a double salt of aluminum sulfate and potassium sulfate. Its molecular formula is K 2 SO 4 ·Al 2 (SO 4 ) 3 24 hours 2 O, the molecular weight is equ...
