Description
Technical field
The invention belongs to technical field of sewage, more particularly to a kind of modularized artificial wetland Water tight and uniform fluid flow
Property control method, be particularly suitable in short-term, emergent sewage disposal and the lower rural area of the density of population, Small Town Wastewater processing.
Background technology
Artificial swamp is a kind of dirty water living creature processing technique to grow up phase late 1970s.The technology is due to tool
There is investment and operating cost is low, maintenance management is convenient, is particularly suitable for fund and the relatively backward rural area of technology.
Under this overall background of China's rural environment Concetrated control, which has obtained widely promoting the use of.However, being run on the spot
Cheng Zhong, it has been found that although the technology has the advantages that maintenance management is convenient, also have the shortcomings that can not significantly regulating and controlling.It removes
Outside the influent load of system, content that administrative staff can regulate and control is simultaneously few.Controllable poor performance is most of at present artificial
, such as there is the major reason of substrate clogging in wetland operation failure.To improve the operational flexibility of artificial wet land system and controllable
Property, to artificial swamp carry out modularization transformation by be technology future developing direction.However, by traditional artificial wetland by monoblock
After wetland is divided into several small modules, the streamflow regime in artificial swamp will be had an important influence on.Whether water distribution is uniformly straight
It connects and is related to wetland whether being capable of stable operation.Therefore, the present invention is directed on present in artificial wetland modules transformation process
Problem is stated, a kind of control method of modularized artificial wetland Water tight and flow uniformity is provided.
To achieve the goals above, the technical solution adopted by the present invention is：
A kind of modularized artificial wetland Water tight and flow uniformity control method, the modularized artificial wetland is by several
A module is formed by way of series, parallel or connection in series-parallel combination, and module 1 is located at water inlet end, by pretreated sewage
It is introduced into water distributing trough 26 before entering modularized artificial wetland, water distribution tracery wall 27 is equipped between water distributing trough 26 and module 1, makes sewage
The Uniform Flow on entire matrix section.
Only be directly connected to own mechanical component between the modularized artificial wetland adjacent module and module, module with
Inlet and outlet pipes need not be set between module, be greatly reduced it is traditional by monoblock artificial wet land system modularization segmentation cause
The interference to sewage moisturizing uniformity on Wetland Substrate cross section.
The mechanical component is lock 14, is provided with watertight rubber circle 13 between the adjacent module and module, can prevent
It is only flowed between gap of the sewage between module and matrix unit, ensures to enter all dirts in specific artificial Wetland Substrate unit
Water can improve the validity of system section water distribution by Wetland Substrate.
There are gap between the modularized artificial wetland adjacent module and module, it is not filled with Wetland Substrate in gap,
By the way that overflow plate 22 is arranged, realizes again sub-distribution of the sewage between module and module, ensure the uniform fluid flow between downstream module
Property is not interfered by up-stream module.Compared with traditional artificial wet land sewage treating process, ensureing flow in Wetland Substrate section
On moisturizing uniformity on more advantage
Each module includes cubical frame 12, and matrix unit one is disposed with along water (flow) direction in frame 12
3, matrix unit 24 and matrix unit 35, wherein be to fill out in matrix unit 1, matrix unit 24 and matrix unit 35
Material 28, the filler 28 is made of filling block 1, filling block 27, filling block 38 and the filling block 49 being distributed from bottom to top,
Packing material size therein is sequentially reduced, and has independent draw ring 2 11 on each filling block, between filling block and filling block, matrix list
Member and matrix unit between and matrix unit and frame 12 between, be both provided with non-woven fabrics 25, with block water each gap it
Between flow.
The matrix unit 1 is identical with the structure of matrix unit 35, is up-small and down-big bucking ladder structure, matrix
Unit 24 be up big and down small bucking ladder structure, be stuck between matrix unit 1 and matrix unit 35, matrix unit 1 by
It is moved to the left to extruding to the left, further compresses the watertight rubber circle 13 of water inlet end；Matrix unit 35 by the right squeeze
It presses and moves right, the watertight rubber circle 13 of further compression module water outlet keeps the Water tight of module more preferable.
The side wall Transverse to the flow direction of the framework 17 of the matrix unit 1, matrix unit 24 and matrix unit 35 is equal
Even to open up several permeable holes 18, the average equivalent dynamics of the seepage channel of the bore dia of permeable hole 18 with sewage in filler is straight
Diameter is suitable, is conducive to water Uniform Flow in module.Framework 17 is made of waterproof material, close between outer wall and module inner wall
Contact.
The system water outlet setting catch basin 23 of the modularized artificial wetland, catch basin 23 overflow with the setting of last intermodule
Water plate 22, the height by adjusting overflow plate 22 control the depth of water of each artificial wetland modules, enhance the uniform fluid flow of artificial swamp
The Modulatory character of property and water level.
In module, the filler of same particle size is laid at same depth of water, under the premise of ensureing contaminant-removal properties to the greatest extent
The filler of same grain size, flow uniformity in guarantee system may be used.
Compared with prior art, the beneficial effects of the invention are as follows：
The configuration of the present invention is simple, easy for installation, the construction period is short, stable, and debug time is short, and treatment effect is high.
Performance of Constructed Wetlands Substrates block when, it is not necessary to stop bed rest and reorganization can restore its partial permeability, need not more replace on a large scale, excavate it is wet
Ground filler only needs to change and blocks module or matrix unit, greatly reduces wetland operation and maintenance cost.
The present invention can be achieved now to fill current, greatly shorten the time that artificial swamp reaches high treatment efficiency；Artificial swamp mould
Block can global transfer, strange land is built, will not permanently be taken up an area again；When wetland blocks, filling block or matrix unit are lifted
Draw ring proposes blocking portion, changes new filling block or matrix unit；Old module, matrix unit and interior filler, pass through after returning factory
It safeguards, regeneration is, it can be achieved that repeatedly utilization, avoids the wasting of resources.
The present invention realizes quick-replaceable and blocks module, extends the artificial swamp service life, improves wetland variation efficiency, is artificial
Wetland applies in the sparse rural area of population, samll cities and towns and outlying mountain area, provides advantageous embodiment.
The present invention realizes accurately controlling for modularized artificial wetland Water tight and flow uniformity.
