Description

Pressure type ceramic tubular membrane hardness and silicon removal integrated system
Technical Field
The invention belongs to the technical field of water treatment hardness and softening treatment devices, and particularly relates to a pressure type ceramic tubular membrane hardness and silicon removal integrated system.
Background
In the treatment of industrial waste water with high hardness and containing silicon, the chemical softening method is the most mature and commonly used method. The traditional process comprises the following steps: water to be treated → coagulant reaction tank → hardness-removing medicament coagulation reaction tank → flocculation reaction tank → sedimentation tank → effluent, and the process treatment has some disadvantages: the process treatment flow is long, the chemical reaction time of the system is long, so that the volume of the tank body is enlarged, and the occupied area of the whole process is large; the effluent quality of the system is unstable, and auxiliary agents such as amide and the like need to be added for flocculation and precipitation reaction, so that the adding cost of the agents is high; after flocculating agents such as amide and the like are added, a large amount of sediment is generated in the sedimentation tank, the sludge amount is greatly increased, and the subsequent sludge treatment cost is greatly increased. In recent years, the traditional treatment process is replaced by an organic tubular membrane hardness and silicon removing device, and the process flow is as follows: the water to be treated → a coagulant reaction tank → a hardiness removing medicament coagulation reaction tank → a flocculation reaction tank → organic tubular membrane filtration → water discharge, the organic tubular membrane adopted in the treatment process has some disadvantages: in order to prevent pollutants from forming enrichment on the surface of the organic tubular membrane and causing fouling of the membrane in the operation process, cross-flow high-speed scouring needs to be formed on the surface of the membrane to prevent fouling of the membrane, so that most of energy consumption of the water pump is used for circulating cross-flow scouring due to the high-speed cross-flow scouring, a large amount of energy consumption is consumed, and the operation cost is greatly increased; the system can form a large amount of solid particles after adding the chemical agent for removing hard silicon, and the solid particles generated after adding the chemical agent can cause abrasion to the surface of the organic membrane tube due to the cross-flow high-speed scouring on the membrane surface, so the process has higher requirement on the material strength of the membrane, and the total investment cost of the system is higher because foreign inlet membranes are mostly adopted at present; the system operates under the working condition for a long time, the solid particles wear the surface of the membrane tube for a long time, the water quality effect of produced water is reduced, the service life of the membrane is greatly shortened, the replacement period is short, and the maintenance cost of the system is greatly improved.
