Description
Technical field
The utility model relates to water-treatment technology fields, and in particular to a kind of artificial wet land system.
Background technique
Artificial swamp is the ground similar with marshland by manually building and controlling operation, and sewage, sludge are had control
Dosing to the wetland through manually building on, sewage and sludge mainly utilize soil, people during flowing in a certain direction
Work medium, plant, the physics of microorganism, chemistry, the triple synergistic effects of biology, a kind of technology that sewage, sludge are handled.
Artificial swamp is divided into surface current artificial wetland (FWS) and drowned flow artificial wet land by unusual in the way of Inlet and outlet water water distribution
(SFS).Surface current artificial wetland's essential characteristic is mainly that sewage flows on the upper layer of soil, and the water surface is directly contacted with air.It is this
The sewage that the artificial swamp of type is relatively suitble to processing pollutant concentration less high, design is simple, and operating cost is low, but load
Low, dirt-removing power is also limited, and is influenced by natural climate condition big, takes up a large area, sewage, which directly exposes earth's surface, to be produced
Raw stink.The water intake mode of drowned flow artificial wet land is from top to bottom to intake, and sewage is even into packed bed bottom, inside wetland
Reacted, the water outlet after reacting by outlet pipe be discharged, therefore subsurface flow wetland system can make full use of root system of plant with
And it is enriched in the biomembrane of stromal surface.
According to water flow to difference, drowned flow artificial wet land can be divided into two kinds again: horizontal drowned flow and vertical subsurface flow.Horizontal drowned flow
Wet land system hydraulic loading and pollutional load are larger, to the processing such as COD, biochemical oxygen demand (BOD), suspended solid and heavy metal
Effect is good, but since air reaeration is ineffective, and plant root zone oxygen release amount is again limited, so nitrification ability is poor, to ammonia nitrogen and always
The removal rate of nitrogen is relatively low;Vertical subsurface flow wetland can be divided into upstream, downstream and three kinds of tidal current, waterpower shape again
Condition combines the characteristics of free water surface wetland and horizontal subsurface flow wetland.Removal rate ratio of the vertical subsurface flow wetland system to COD, TN
Horizontal drowned flow artificial wet land wants high, and anti-load impact ability is strong, cost of investment is few, running cost also use it is low, but relative to
Horizontal drowned flow artificial wet land, the ability that vertical subsurface flow wetland removes organic matter is bad, and vertical subsurface flow wetland is set
It is standby to require high, operational process complexity.In short, drowned flow artificial wet land climate influences smaller, the higher cost of construction, matrix
It is easy to block, so that water flow on surface be caused to stagnate, the longtime running to system is simultaneously unfavorable.
Nowadays pollutant component is complicated in many sewage, and fluctuation of concentration is big, and due to wetland longtime running, some to be difficult to
The larger molecular organics and suspended matter of degradation, which are largely accumulated in wet land system, to result in blockage, after blocking, artificial swamp system
The infiltration coefficient of the matrix of system can sharply decline, and discharge capacity also decreases, a large amount of direct heaps of sewage for introducing wet land system
On wetland surface, long-term ponding causes stench, mosquitos and flies is caused to breed product, influences surrounding enviroment.
