Description
Technical field
A kind of compound flow constructed wetland sewage disposal system is the utility model is related to, belongs to water-treatment technology field.
Background technology
Artificial swamp (Constructed wetland) is the new skill of a kind of wastewater treatment to grow up in the last thirty years
Art.1974, since preceding West Germany builds artificial swamp first, the technology was in the U.S., Canada and some European developed countries
Developed rapidly.The research of China's artificial swamp is started late, and it is wet that China's first man work is built up in Shenzhen July nineteen ninety
Ground sewage treatment project-white clay hole artificial marsh sewage treatment system.Since the 1970s, artificial swamp water technology
Start to be concerned by people, there is Low investment, low energy consumption, turn into the study hotspot of water environment technology.
Artificial swamp be for processing sewage and artificially on the depression for having certain length-width ratio and the bottom surface gradient with soil and
Filler (such as gravel) mixing composition packed bed, makes sewage be flowed in the filler gap of bed body or in bed body surface flow, warp
The multiple-microorganism activity of sandstone, soil filtering and plant rhizosphere, is handled sewage, water quality is purified.Artificial swamp
Cleaning principle be that sewage is handled by the synergy of the physics in wetlands ecosystems, chemistry and biological three, pass through
Filtering, absorption, precipitation, ion exchange, microbial assimilation are decomposed and the approach such as plant absorption removes suspension in waste water, organic
Thing, nitrogen, phosphorus and heavy metal etc., it has, and operating cost is low, maintenance management is simple, it is small that surrounding enviroment are influenceed, can be with decentralized
The characteristics of being built with miniaturization.
P elements, generally quilt are removed using the matrix in artificial wet land system, water plant and the collective effect of microorganism
It is considered a kind of cheap effective wastewater processing technology.Artificial swamp in stromal surface above and below, can be divided into by water level
Surface current artificial wetland and drowned flow artificial wet land two types.Drowned flow artificial wet land can be divided into horizontal latent again according to water (flow) direction
Stream, vertical subsurface flow and composite underflow three types.At present, artificial swamp shows in wastewater treatment and eutrophied water treatment
Go out great advantage, there is suitable vast potential for future development.But because people are shorter to the search time of artificial swamp, in reality
Many deficiencies are still suffered from application process, as pollutant burden is low, oxygen supply is insufficient, dwell time of sewage is short, wetland easily blocks, takes off
Nitrogen phosphor-removing effect is undesirable, easy formation slough and floor space are big etc..
Vertical current constructed wetland can be divided into three kinds of upstream, downstream and tidal current, and its hydraulic condition combines surface
The characteristics of flowing wetland and horizontal subsurface flow wetland.At present the vertical compound flow constructed wetland processing method of sewage be mainly downstream with it is upper
Row flows compound, is primarily present following weak point：(1) artificial wet land system of descent activation complex form is to pollution
The removal effect of thing is not very good, easily causes current and leads to not smooth, filler infiltration coefficient reduction, the decline meeting of water penetration speed
Extend hydraulic detention time, cause the oxygen in downstream pool surface formation ponding layer hinders air to enter hypothallus, make
Obtain the aerobic microbiological activity decrease in composite vertical current.(2) system entirety anoxic, oxygenation capacity are relatively low.Although batch (-type) enters
Water improves oxygen situation, but the dissolved oxygen in water inlet has been consumed to very low level in downstream tank, it is impossible to provides good nitre
Change acts on environmental condition, it is impossible to produces substrate of a large amount of nitrate as denitrification, makes nitrification-denitrification approach not smooth
It is logical, limit nitrogen removal rate.(3) carbon source required in denitrification process cannot sufficiently ensure to further suppress always
The removal effect of nitrogen.(4) phosphor-removing effect of matrix is not highly desirable.
There is water barrier at horizontal subsurface flow wetland bed bottom, longitudinally there is the gradient.Throw in the cloth ditch that sewage is constructed from water inlet end along bedside
Enter in bed, advance along filler bottom undercurrent in horizontal diafiltration, flowed out from other end exhalent canal.Rely primarily on physics, chemistry, biology
Synergy complete waste water purification process, make full use of the biomembrane of filler superficial growth, abundant root system of plant and table
Layer soil and the effect of filler retention etc., improve heavy metal and the suspended solid SS effect of damming, strengthen natural wetland ecosystem
The dirt-removing power of system.Horizontal subsurface flow wetland system hydraulic load and pollutional load are larger, and COD (COD), biochemistry are needed
The high treating effects such as oxygen amount (BOD), suspended solid (SS) and heavy metal, but because air reaeration is ineffective, plant roots area is released
Oxygen amount is again limited, so nitrification ability is poor, to the clearance of ammonia nitrogen and total nitrogen (TN) than relatively low.
Research for many years shows, selects the big emergent aquactic plants of biomass such as reed, cattail and prominent bio-diversity is special
Color has good effect to pollutant removal；Different matrix is different to the purification efficiency of pollutant, and zeolite and ceramics are right
The removal effect of total nitrogen and ammonia nitrogen is good, and blast furnace slag, anthracite, slag, flyash have the ability for preferably going dephosphorization, then
Multistage wetland is arisen at the historic moment, and different plants and matrix or compound wetland is established effectively to remove various pollutants by arranging in pairs or groups
Matter, but nowadays pollutant component is complicated in many sewage, and fluctuation of concentration is big, and traditional artificial wet land system can not be solved effectively
These problems；Additionally, due to wetland longtime running, some be difficult to the larger molecular organicses degraded and suspension be largely accumulated in it is wet
Resulted in blockage in ground system, this is also to hinder one of artificial swamp development and the major reason promoted.
At present, the popularization and application of domestic Artificial Wetland Techniques are also mainly the wet land system of single flow pattern, cause to protect
Demonstrate,proving various contamination indexs has higher clearance, and outlet effect is undesirable, and artificial wet land system easily causes blocking.
