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, the density of putting filter-feeding fish in a suitable place to breed is 50 ~ 100g/m
3;
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; Filler in packing layer a is vermiculite, zeolite, and 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; Filler in packing layer b is vermiculite, zeolite, and particle diameter is 5 ~ 20mm, and porosity is 40% ~ 50%;
Described horizontal drowned flow artificial wet land and vertical subsurface flow wetland plant emergent respectively;
Described physical adsorption district is provided with natural pebble and zeolite.
Preferably, described filter-feeding fish selects silver carp, the initial stocking size of silver carp be 1 age fish, long about 20 centimeters of its body.
Preferably, described emergent is one or more in reed, raupo and Scirpus tabernaemontani.
Beneficial effect of the present invention is:
(1) the present invention can effectively reduce sewage effluents pollutant load, it is a kind of effective ecologic assemblage type reuse water supply river course further treatment technique, make reuse water realize ecology and resource utilization, expense is lower, has very large actual application value and promotional value.
(2) reuse water supply river course of the present invention further treatment technique is a kind for the treatment of technology filter-feeding fish ecological pond, two-stage combination current wetland, three kinds, physical adsorption district process combination got up, hydrobiont is repaired and combines with wetland recovery technique, greatly improve the ecological purification effect to reuse water, reduce each cell processing load, especially in reduction artificial wetland treatment load, enhancement process effect, reduce to safeguard pressure and have good effect in increasing the service life.
(3) filter-feeding fish ecological pond not only increases water transparency, reduces water nutrition load, slows down artificial swamp substrate clogging problem, reduces artificial wetland treatment load, also has good ecoscape effect in addition.
