Description
Affiliated technical field
The present invention relates to the flocculation sedimentation tank that a kind of desalinization preliminary treatment is used.
Background technology
" seawater desalination " also claimed in desalinization, promptly removes salinity in the seawater to obtain the technical process of fresh water.Desalinization is the increment technique of increasing income that realizes the water resource utilization, can increase the fresh water total amount, and not receive space-time and climatic effect.Water quality is good, price is gradually reasonable, can ensure coastal resident's drinking water and water for industrial use demand.
The target of desalinization forward high efficiency, low energyization and scale development in the world in recent years, counter-infiltration (SWRO), multistage flash evaporation (MSF) and multiple-effect evaporation (MED) more become the main flow that is applicable to large-scale desalination technology.
Large-scale desalinization project is a unusual complicated system engineering often.With regard to main processes, comprise sea water preprocessing, desalination, desalination water post processing etc.Wherein preliminary treatment is meant that the device that has got into the desalination function at seawater before to its necessity of doing processing, removes marine growth as killing, and reduces turbidity, removes suspension (to hyperfiltration), or outgas (to the way of distillation), the medicament that interpolation is necessary etc.The pre-processing device that adopts has flocculation sedimentation tank, filter tank, UF, MF etc. usually; Desalination then is to remove the salinity in the seawater through above-listed a certain method; It is the core of whole desalination system; This process often need solve the anticorrosion of equipment and antiscale problem except that requiring efficient desalination, also require to have corresponding energy recovery measure in some technology; Post processing then is the product water to different desalination methods, to processing such as regulating and controlling water quality that different customer requirements carried out and storings.
The flocculation sedimentation tank of conventional water treatment process can't satisfy the particular surroundings of seawater medium, and the flocculation sedimentation tank that is used for desalinization need satisfy himself special requirement.In order to overcome the deficiency of prior art, be necessary to develop the flocculation sedimentation tank that satisfies the desalinization specific (special) requirements.
Summary of the invention
In order to fill up the blank of existing flocculation sediment pool technology, the present invention provides a kind of desalinization preliminary treatment to use flocculation sedimentation tank.This flocculation sedimentation tank has solved the endurance issues of structures and material in the corrosive environment of sea water.The sealing of flocculation sedimentation tank water string; There is following problem in the water string atlas 02S404 that publishes according to China Inst of Architectural Standard Design: 1, because there are foozle in aqueduct and steel sleeve pipe through walls; Cause in the practice of construction process seal clearance between the aqueduct and steel sleeve pipe through walls less than normal, can't require fill out encapsulants such as breaking asbestos cement according to atlas; 2, because thickness of wall body surpasses 500mm, tool using can't seal tight when filling out encapsulants such as breaking asbestos cement; 3, common asbestos cement seawater corrosion resistance for a long time.The invention solves the sealing and the seawater corrosion resistance problem of flocculation sedimentation tank water string.
The technical solution adopted for the present invention to solve the technical problems is: flocculation sedimentation tank is used in a kind of desalinization preliminary treatment, and the flocculation sediment tank main body adopts reinforced concrete structure.Because flocculation sedimentation tank is inner, the outside all is in the corrosive properly media environment, and concrete and inner reinforcing bar are had corrosivity.For improving the flocculation sedimentation tank durability, in concrete, add the RMA anticorrisive agent of seawater corrosion resistance; With the contacted concrete inner surface of seawater, the anticorrosive paint of brushing sea water resistance; Reinforcing bar brushing reinforcing bar rust remover in the concrete; Metalwork with contact with sea water in the pond all adopts high alloy two phase stainless steel S32205 (ASTM), and nonmetallic materials adopt the material of seawater corrosion resistances such as FRP fiberglass reinforced plastics, the second third copolymerization engineering plastics, UPVC and EPDM rubber.
Sea water resistance, ageing-resistant non-toxic material are adopted in the sealing of flocculation sedimentation tank water string, meeting between aqueduct and steel sleeve pipe through walls, the elongated twice expanded rubber of laying specification 20mm * 30mm of each annular of back side.Do not leak encapsulant in the expanded rubber outside with rapid hardening water and bury aluminium alloy sealing grouting syringe needle underground, the position is in the water string bottom.Meeting, between the back side twice expanded rubber, selecting for use the cyanogen that adds auxiliary agent to coagulate the TPT grouting material through aluminium alloy sealing grouting syringe needle high-pressure injection chemical sizwe, till water string overhead stream slurry.Remove the grouting syringe needle and accomplish seal operation.
The invention has the beneficial effects as follows: relate to a kind of flocculation sedimentation tank that is used for the desalinization pretreating process.In the flocculation sedimentation tank concrete, add seawater corrosion resistance anticorrisive agent, with the anticorrosive paint of the contacted concrete inner surface of seawater brushing sea water resistance, concrete in all adopt high alloy two phase stainless steel S32205 (ASTM), nonmetallic materials to adopt the material of seawater corrosion resistances such as ERP fiberglass reinforced plastics, the second third copolymerization engineering plastics, UPVC and EPDM rubber with the metalwork of contact with sea water in the reinforcing bar brushing reinforcing bar rust remover, pond.Improved the durability of flocculation sedimentation tank; The sealing of water string adopts cyanogen to coagulate TPT grouting material high-pressure injection chemical sizwe, has solved because foozle and body of wall are blocked up, causes the water string can't tight seal and encapsulant seawater corrosion resistance problem not.
