Current considerable part city water resource shortage, urban water shortage scope constantly expands, and degree of water shortage is on the rise, and need to take joint
About with water, water conservation, open up the measures such as new water source and alleviate water resources crisis.With municipal sewage as water source, through suitably
After process, it is back to water for industrial use, agricultural water, urban reclaimed water, water-use for environment and for make-up water source water etc., including
Building and one residential reclaimed water reuse.This reclaimed water reuse method be the most effectively develop Discussion about Unconventional Water Resources measure it
One, owing to it has the advantages such as water source is reliable and stable, processing cost is relatively low, the most increasingly paid attention to by various countries.Recycled water
Depth treatment technology currently mainly includes: the filtration of chemical coagulation and precipitation filtering technique, coagulating sedimentation, microfiltration, ozone technology,
The physicochemical techniques such as super magnetically separating and purifying technology, it is the most relatively conventional mode that sewage treatment plant tail water carries out Ecological Disposal.
At present, utilize Combination System of Constructed Wetland to process sewage disposal plant effluent both at home and abroad and recharge river course technology many engineering cases
Example, artificial swamp runs and is As time goes on easily generated substrate clogging problem, mainly part nutrient substance, microbial metabolism
Product, wastewater suspended substance, plant decay root system blocking filler hole.In order to reduce Wastewater Treatment by Constructed Wetlands load, improve people
Work wetland group technology entirety purifies water effect, is wherein no lack of and combines case with the unit such as stabilization pond, ecological pond, but Ren Rancun
At body eutrophication, artificial swamp runs and is As time goes on easily generated substrate clogging problem.
Summary of the invention
It is an object of the invention to the shortcoming overcoming prior art to exist, seek to design a kind of recycled water Wetland ecological cleaning system,
By artificial swamp and biological restoration combination technique, improve the ecological purification effect to recycled water, reduce each unit and process load.
To achieve these goals, the technical solution used in the present invention is: a kind of recycled water Wetland ecological cleaning system, including again
Raw water pipe, filter-feeding fish ecological pond, horizontal drowned flow artificial wet land, vertical subsurface flow wetland, physical absorption district, described
Recycled water pipeline is connected with filter-feeding fish ecological pond water inlet, filter-feeding fish ecological pond outlet and horizontal drowned flow artificial wet land
Water inlet is connected, and horizontal drowned flow artificial wet land outlet is connected with vertical subsurface flow wetland water inlet, vertical subsurface flow wetland
Outlet is connected with physical absorption district water inlet, and physical absorption district outlet is passed through river；
Plant planting submerged plant bottom described filter-feeding fish ecological pond, put filter-feeding fish in a suitable place to breed in filter-feeding fish ecological pond, put in a suitable place to breed
The density of filter-feeding fish is 50～100g/m3；
Described horizontal drowned flow artificial wet land is respectively arranged with top layer soil layer, packing layer a, gravel supporting layer from top to bottom；Packing layer a
In filler be Vermiculitum, zeolite, particle diameter is 10～30mm, and porosity is 40%～50%；
Described vertical subsurface flow wetland is respectively arranged with top layer soil layer, packing layer b, gravel supporting layer from top to bottom；Packing layer b
In filler be Vermiculitum, zeolite, particle diameter is 5～20mm, and porosity is 40%～50%；
Emergent aquactic plant is planted respectively on described horizontal drowned flow artificial wet land and vertical subsurface flow wetland；
Described physical absorption district is provided with gravel by nature and zeolite.
Preferably, described filter-feeding fish select Hypophthalmichthys molitrix, the initial stocking size of Hypophthalmichthys molitrix be 1 age fish, its body length about 20 centimeters.
Preferably, one or more during described emergent aquactic plant is phragmites communis, Typha angustifolia and Herba Scirpi Tabernaemontani.
The invention have the benefit that
(1) present invention can effectively reduce sewage effluents pollutant load, is a kind of effective ecological assemblage type recycled water supply river
Road further treatment technique, makes recycled water realize ecology and resource, and expense is relatively low, has the biggest actual application value and promotional value.
(2) recycled water of the present invention supply river course further treatment technique is that one is by wet to filter-feeding fish ecological pond, two-stage combination undercurrent
The treatment technology that ground, three kinds of physical absorption district process combination are got up, repairs aquatile and combines with wetland recovery technique,
Be greatly improved the ecological purification effect to recycled water, reduce each unit and process load, especially reduce artificial wetland treatment load,
Enhancement process effect, reduction safeguard that pressure and the aspect that increases the service life have good effect.
(3) filter-feeding fish ecological pond not only increases water transparency, reduces water nutrition load, slows down artificial swamp substrate
Blockage problem, reduces artificial wetland treatment load, the most also has good ecoscape effect.
