Abstract
The invention discloses a rapid fabricated type constructed wetland filler unit comprising an outer frame skeleton of a rigid polyvinyl chloride pipe and elastic packing fixed on the outer frame skeleton. The spacing interval between the elastic packing is 100 to 200mm. The invention at the same time provides a wastewater treatment system on the constructed wetland which is built by adopting the fabricated type filler unit. The wastewater treatment system on the constructed wetland comprises a soil layer, a soil-insulation layer, a supporting layer, an artificial filler unit layer, a gravel supporting layer and an impervious layer from top to bottom. The rapid fabricated type constructed wetland filler unit adopts modular design and can be mass produced in a factory. The wastewater treatment system on the constructed wetland built by the fabricated type filler unit has great biomass, short hydraulic retention time and good treatment effect. Furthermore, the system cannot be blocked and can be repaired; the operation cost is low and the earth can be repeatedly used.
Description
Technical field
The present invention relates to the ecological water treatment project, be specifically related to a kind of quickly assembled sewage treatment system for artificial wet land and filler unit thereof.
Background technology
" wetland " general reference temporarily or for a long time covers lowland, the more grassy marshland of soil water-filling that the depth of water is no more than two meters, and the time of low water depth of water is no more than six meters coastland, comprises that various salt water pantanos ground, aquiprata, lake, river and floodplain, estuarine delta, peatlands, seabeach, lake are coated with, depression, river bank or overbank, wet grassland etc.Wetland is the ecosystem that has multiple unique function on the earth, it not only provides a large amount of foods, raw material and water resources for the mankind, but also play an important role at aspects such as keeping the eubiosis, maintenance species diversity and rare animal resource and water conservation, additional underground water, enjoy the good reputation of " kidney of the earth ".
The ultimate principle of artificial swamp biopurification technology is: the elite plant of plantation on certain filler, sewage is rendered on the wetland that is similar to the marsh of artificial construction.When effluent stream is crossed artificial swamp, to filter through sandstone, soil, the multiple microbial activities of plant rhizosphere is purified water quality, is simulation and reinforcement to natural wet land system.
The filler that the tradition wetland adopts usually is a graded gravel.There is following problem in conventional filler: the ability of degraded of (1) artificial swamp or absorb polluted matter depends on the probability that sewage contacts with filler, and the structures shape of conventional filler its enough touch opportunities are provided can not for sewage and filler, provide enough big attaching surface to microorganism, finally influence the scrubbing effect of wetland, can not bring into play the cleaning action of wetland to the full extent; (2) for the filler in the artificial swamp, except considering its adsorptive power, also should improve the composition of filler to pollution substances such as phosphorus, the breeding and the growth that are each quasi-microorganism provide adapt circumstance; (3) conventional filler density is very big, and earth volume is big, and for guaranteeing that filler by evenly filling of layer, does not destroy the grating and the anti seepage membrane of filler, all construction relies on and manually finishes; Bring very big inconvenience for transportation and construction, expend plenty of time and manpower.(4) recoverability of traditional artificial swamp is poor, in case stop up, is difficult to recover, and need carry out whole tilting table to wetland and handle, operational difficulty, quantities is big; (5) traditional artificial swamp is restricted because of uniformity of water distribution, and internal load there are differences, and microorganism growth speed is inhomogeneous, in case the inner somewhere of wetland short flow phenomenon will occur because of stifled match appears in the microorganism hypertrophy.
Goal of the invention
In view of this, for solving the deficiency that present artificial swamp exists, realize the quick modularization assembling of artificial swamp, shorten construction period and difficulty, the invention provides a kind of novel quick assembled type artificial swamp filler unit, this artificial swamp filler unit porosity height, possesses good waterpower penetration performance, specific surface area is big, can effectively improve the amount of microorganism in the artificial swamp, reduce the possibility of artificial swamp silting, effectively avoid dead stream, short stream, can realize quick modularization assembling simultaneously, shorten construction period, reduce difficulty of construction.
