Abstract
The utility model discloses a composite flow artificial wetland structure for treating chromium-containing wastewater. The structure is characterized in that one end of an artificial grid tank (1) is communicated with a water inlet pipe, the other end of the artificial grid tank (1) is communicated with an adjusting tank (2), and the adjusting tank (2) is sequentially communicated with a primary vertical flow artificial wetland (3), a primary horizontal subsurface flow artificial wetland (4), a primary surface flow artificial wetland (5), a secondary vertical flow artificial wetland (6), a secondary horizontal subsurface flow artificial wetland (7) and a secondary surface flow artificial wetland (8); and purification plants are grown in each artificial wetland.
Description
Technical field
The utility model relates to a kind of artificial swamp structure, particularly a kind of compound flow constructed wetland structure.
Background technology
Electroplating wastewater shared proportion in trade effluent is less, but because Electroplating Production pollutant discharge amount is large, waste water complicated component, especially heavy metal wastewater thereby are the great waste water classifications of potential hazard in Electroplating Operations.Therefore, the improvement of electroplating wastewater is all a very important problem all the time.Be positioned at the Jinhua Qing Hu Electroplate Factory in Su Meng township, Jinhua in recent years because wastewater discharge increases, cause through still severe overweight of chemical precipitation heavy metal out of electroplating wastewater concentration after treatment, " integrated wastewater discharge standard " (GB8978 1) that does not reach national regulation is far away extremely serious to the environmental pollution of periphery resident living.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of compound flow constructed wetland structure of energy processing waste water containing chrome, to solve the problem of the pollution of waste electroplating liquor containing chromium to environment.
The technical solution of the utility model is: a kind of compound flow constructed wetland structure of processing waste water containing chrome, artificial grating tank one end is communicated with water inlet pipe, the other end is communicated with equalizing tank, rear equalizing tank is connected with one-level vertical current constructed wetland, one-level horizontal drowned flow artificial wet land, one-level surface current artificial wetland and secondary vertical current constructed wetland, secondary horizontal drowned flow artificial wet land and secondary surface turning flow artificial wetland successively, all plants purifying plant in each artificial swamp.
The coarse rack that artificial grating tank comprises 20 ㎜ and the fine fack of 5 ㎜.
In equalizing tank, add fenton reagent.
One-level vertical current constructed wetland and secondary vertical current constructed wetland are all communicated with upper level pond by water distributor.
In one-level vertical current constructed wetland, add successively from the bottom to top gravel bed, coarse sands layer, wherein coarse sand particle diameter is 1-2cm, and grain size of gravel is 3-5cm.
In one-level horizontal drowned flow artificial wet land, secondary horizontal drowned flow artificial wet land and secondary vertical current constructed wetland, add successively from the bottom to top gravel bed, coarse sands layer and fine sand layer, wherein fine sand particle diameter is 0.2-0.4cm, coarse sand particle diameter is 1-2cm, and grain size of gravel is 3-5cm.
Purifying plant in one-level vertical current constructed wetland and secondary vertical current constructed wetland is Herba Eichhorniae, barnyard grass, thatch barnyard grass or power flower again.
Purifying plant in one-level horizontal drowned flow artificial wet land and secondary horizontal drowned flow artificial wet land is yellow flag, reed, Spiked Loosestrife or Canna generalis Bailey.
The purifying plant of one-level surface current artificial wetland and secondary surface turning flow artificial wetland is macro.
The beneficial effects of the utility model: can more be better than other single botanical systems, efficiently enrichment chromium in comprehensive removal heavy metal chromium aspect by combinations of plant system.In the time using various plants combination, be conducive to learn from other's strong points to offset one's weaknesses between plant, keep comparatively stable purifying chromium-containing wastewater efficiently, this kind of artificial swamp structure can reach more than 85% the clearance of chromium.
