Description
Technical field
The present invention relates to a kind of water processing establishment one flocculation sedimentation tank, be specifically related to the efficient horizontal sedimentation tank of a kind of short distance.
Background technology
Current, the resource of water supply of China municipal administration water factory is mainly river, Lake Water and reservoir water, and the water of Economic development association pollutes and caused the pollution of river serious, for the water that turns over that increase water resources is carried out is put in storage, cause Reservoir Water Quality to be worsened equally, water treatment difficulty is strengthened; And along with Economic development, the size of population increases, municipal water supply demand strengthens gradually, makes water supply problem further outstanding.Some old municipal water factories due to water supply capacity a little less than, processing unit falls behind, water supply quality, the water yield are all difficult to meet modern water requirements, the reconstruction and extension project of municipal water factory has been extremely urgent.The reconstruction of Dan Lao factory, place is very limited, and traditional water technology floor space is large, processes the water yield little, in the situation that former civil engineering main body is motionless, reconstructs, and is difficult to meet water requirements.Especially summer, resource of water supply grew algae, in winter low temperature, low turbid situation, had more increased the operating load of water factory.Meanwhile, new < < drinking water sanitary standard > > (GB5749-2006) implemented on July 1st, 2007, and new standard set quota is increased to 106 by 35 of primary standard (GB5749-85).The problems referred to above all handling technology of water supply are had higher requirement.
At present conventional flocculation process adopts grid (grizzly bar) flocculation basin, and depositing technology adopts counterflow tilted plate (inclined tube) precipitation or horizontal sedimentation tank.Grid flocculation is characterized in that flocculation basin to be divided into many vertical shafts, and current vertical folding refluxes moving, until outlet.In vertical shaft, Transverse to the flow direction is placed grid or grizzly bar, when current pass through, forms certain disturbance effect.Parallel plate or parallelpiped (sometimes can utilize honeycomb filler) that the utilization of counterflow tilted plate (inclined tube) settling tank is tilted are divided into a series of shallow layer precipitating layers, to realize the separation of muddy water.
Above-mentioned grid flocculation, counterflow tilted plate (inclined tube) settling tank can meet effluent quality requirement in the situation that raw water quality is good, but the micro-pollution of current former water, summer algae grow, under the low turbid overall situation of winter low temperature, guarantee that effluent quality becomes the challenge that it is difficult to reply.And above-mentioned grid flocculation, counterflow tilted plate (inclined tube) settling tank mostly are level and build jointly, and occupation of land is many, reaction vertical shaft spoil disposal valve is many, easily stops up, and management maintenance workload is large.
Summary of the invention
Main purpose of the present invention is for the problems referred to above, existing flocculation sedimentation tank to be improved, water has realized good flocculating effect under the effect of self-rotary micro swirl flocculation plant, long horizontal gallery has played homogenizing to the water yield of water and water quality simultaneously, then overturn and enter settling region through training wall, A template lateral flow separator for mud and water hold back and rear throwing out under realize the separation of muddy water, thereby guarantee good effluent quality.
The technical solution adopted for the present invention to solve the technical problems is: the efficient horizontal sedimentation tank of short distance, it is characterized in that horizontal gallery type flocculation zone and A template lateral flow settling region connect up and down, between upper and lower twoth district, leaving hole is connected, A template lateral flow settling region water inlet portion is provided with training wall, has equal discharge orifice on wall.One end, A template lateral flow settling region is provided with installation and repairing district.Bottom, A template lateral flow settling region is provided with spoil disposal facility.Horizontal gallery type flocculation zone and A template lateral flow settling region are respectively equipped with core apparatus self-rotary micro swirl flocculation plant and the side direction based on micro-throwing out (level) stream muddy water shunting A type swash plate.
The self-rotary micro swirl flocculation plant (applied for patent of invention, patent is accepted, and application number is 201210395291.X) of the set autonomous invention of core apparatus Shi Wo company in horizontal gallery type flocculation zone.
In A template lateral flow settling region, the side direction based on micro-throwing out (level) the stream muddy water shunting A type swash plate of the set autonomous invention of core apparatus Shi Wo company (has been applied for utility model patent, patent is accepted, and the patent No. is 201320023125.7).
Beneficial effect of the present invention:
1. the present invention superposes flocculation zone and settling region up and down, can greatly reduce floor space, not changing original elevation design, do not increase under the condition of initial cost, realize old water factory propose mark, transformation and upgrade.
The problems such as 2. horizontal gallery type flocculation zone valveless is controlled, and manageability, does not stop up, and has solved conventional mesh flocculation valve many, and management difficulty is large, easy obstruction.
3. the structure of the A type swash plate in A template lateral flow settling region makes shallow layer precipitating theory obtain in actual applications real embodiment, is easy to large-scale industrialized production and application.
4. the present invention is stronger to low temperature and low turbidity water, micro-polluted water adaptive faculty, guarantees the up to standard of effluent quality.
