Description

The composite ecotype micro-electrolysis mobile water body in-situ prosthetic device

Technical field

The invention belongs to sewage disposal, environmental protection technical field, be specifically related to a kind of water body prosthetic device.

Background technology

In the water body recovery technique of sewage disposal, generally adopt methods such as microorganism, plant and chemical agent flocculation sediment at present.But existing method ubiquity treatment efficiency is low, treatment effect is unstable, be subjected to such environmental effects such as temperature big, add the big and problems such as cost height of dose.The development of water body recovery technique rapidly, successively disclosed 200410044014 " mobile landscape water body prosthetic devices ", 200510010789.X " the microorganism colonization biological floating island water body restorative procedure that is used for the great water body Pollution abatement " and 200710061455.4 " city ditch polluted water in situ ecological purifying processing device " or the like of Chinese patent for example, said apparatus exists all that method is single, treatment efficiency is low, treatment effect is unstable, be subjected to problems such as such environmental effects such as temperature are big, can't reach good water body repairing effect.

Summary of the invention

At pressing for of existing water body recovery technique above shortcomings and numerous cities and towns polluted river/lake reparation, the purpose of this invention is to provide a kind of composite ecotype micro-electrolysis mobile water body in-situ prosthetic device, catchment body reparation and ecoscape of this device is one, highly effective has very strong specific aim and adaptability.

The object of the present invention is achieved like this:

A kind of composite ecotype micro-electrolysis mobile water body in-situ prosthetic device, include little bed electrolysis and planting purify bed, this device is the center with the inhalant region at center, the little bed electrolysis of ring, interior ring planting purify bed, the little bed electrolysis of outer shroud and outer shroud planting purify bed in outwards being furnished with successively, and the Inlet and outlet water passage of each is communicated with successively.This device will have the plant bed of Ecological Disposal ability and combine on the basis that makes up based on little bed electrolysis, and forming collection Ecological Disposal and little electrolysis treatment is the compound treatment unit of one.Water inlet is entered by the center inhalant region, and the little bed electrolysis of ring in entering after water pump lifting is by organism and the phosphorus in little electrolysis removal water; Ring planting purify bed in water outlet enters utilizes absorption of plant and the microbial process in the matrix thereof to remove organism and nitrogen phosphorus, and water outlet enters little bed electrolysis of outer shroud and outer shroud planting purify bed, further removes the pollutent in the water body, handles back effluent recycling water body.

Described little bed electrolysis is made of the convenient little electrolysis cells of net cage shape that takes out, so that replenish or clear up the mud in little bed electrolysis.Plantation configuration water cattail, Canna generalis Bailey, reed or cyperus alternifolius in the planting purify bed.

In described little bed electrolysis and the planting purify bed traverse baffle is set, the current through hole staggered arrangement on the adjacent baffle to prolong the current flow process, prevents short stream.

Compared to existing technology, the present invention has following characteristics:

(1) highly-efficient treatment is flexibly stable.Little bed electrolysis is not subjected to such environmental effects such as temperature, can efficiently remove organism and phosphorus; The metal ion that produces of electrolytic process particularly, the dephosphorizing rate height has clear superiority aspect the body eutrophication eliminating.And plant bed absorption and removal organism of the microbial process in the matrix and nitrogen phosphorus by plant have further been strengthened the removal to pollutent, and establish traverse baffle to prolong the current flow process in each annular bed, prevent short stream.In addition, the mobility of device can be according to the pollution condition of water body different sites, the appliance ensure treatment effect of combination different quantities.

(2) ecoscape is effective.Plant bed part in this device can be planted the good various plants such as water cattail, Canna generalis Bailey, reed and cyperus alternifolius of configuration clean effect; But this treatment unit floats on relative fixed in the water simultaneously, can require to do different change in location according to view, makes up different patterns, has good handiness, becomes " mobile potted landscape " and floats on the water.

(3) maintenance management is convenient.In ring and the little bed electrolysis of outer shroud can make the little electrolysis cells of many convenient net cage shapes that take out and constitute so that replenish or clear up mud in little bed electrolysis.

(4) processing cost is low.Little electrolytic system, the formations such as scrap metal slag of available coke cheaply and factory, be simple and easy to, cost is low.Do not have the artificial oxygen replenishing equipment that consumes energy in the device, meet the target of " energy-conservation ", " utilizing again ".

Embodiment

Referring to Fig. 1, Fig. 2 and Fig. 3, the center of this composite ecotype micro-electrolysis mobile water body in-situ prosthetic device is an inhalant region 1, with inhalant region 1 is the little bed electrolysis 2 of ring, interior ring planting purify bed 3, the little bed electrolysis 4 of outer shroud and outer shroud planting purify bed 5 in the center outwards is furnished with successively, and the Inlet and outlet water passage of each is communicated with successively.Be provided with water pump in the inhalant region 1, water inlet is entered by center inhalant region 1, and the little bed electrolysis 2 of ring in entering after water pump lifting is by organism and the phosphorus in little electrolysis removal water; Ring planting purify bed 3 in water outlet enters, utilize absorption and the microbial process in the matrix thereof of plant to remove organism and nitrogen phosphorus, water outlet enters little bed electrolysis 4 of outer shroud and outer shroud planting purify bed 5, further removes the pollutent in the water body, handles back effluent recycling water body.

Little bed electrolysis can be emitted the principle of a large amount of strong oxidizing property radicals by little galvanic cell, the organism in the oxidation removal sewage, and utilize the metal ion that produces in the microelectrolysis process that the phosphorus in the water body is carried out flocculation sediment and remove; Plant bed part in the device is removed organism and nitrogen phosphorus by absorption and the microbial process in the matrix thereof of plant, has strengthened the removal to pollutent.Little bed electrolysis is made of many convenient little electrolysis cells 6 of net cage shape that take out, and is convenient to replenish or clear up the mud in little bed electrolysis.Establish traverse baffle 7 in each annular bed, and current through hole 8 staggered arrangement on the adjacent baffle, to prolong the current flow process, the setting of traverse baffle simultaneously can effectively prevent the short stream of current.

The main technical details of this device:

The residence time: little bed electrolysis total residence time is 1.5h～3h.
