Summary of the invention

The objective of the invention is: propose a kind of the assurance under the ideal water treatment effect prerequisite, need not to be provided with specially the biochemical complex water body treating method of diversion runner, its investment is little, running cost is low, can give full play to environmental protection effect, is adapted at applying in physical environment or the manmade landscape, artificial landscape's water body.

In order to reach above purpose, the present invention is directed to the physical environment pond is the characteristics on the pool, the bottom of a pan substantially, proposes following biochemical complex water body treating method, and its basic step is:

A, in the pond, cultivate active sludge, cultivate naturally or introduce required spawn culture all can, keeping the volume of active sludge is that pond water volumetrical 5%-15% is advisable;

B, the anchor that falls along the border in the pond are settled one group of floating carrier spaced apart, intercalation plantation emergent on the described floating carrier, as calamus, Chinese celery, hay grass, arrowhead, aquatic iris, mullet grass and Spiked Loosestrife etc., the floating carrier geometric centre is advisable with center, distance pond 1/6 to 1/2 average pond radius, and spacing distance 3-5 rice is advisable;

C, unifiedly in floating carrier bottom tangentially settle diving to make the stream biochemical processor (or to claim to make the stream aerator towards the border, is ZL2004200241419 Chinese patent bulletin document referring to the patent No.), the water screw underwater penetration that diving is made the stream biochemical processor is in the darkest 1/8 to 1/2 being advisable in pond;

D, startup diving are made the stream biochemical processor, make the pond form eddy flow.

Like this, floating carrier not only makes water surface emergent and the water-bed active sludge on it form complementary equilibrium water ecotope, help the long-term good water treatment condition that keeps, and the diving under the floating carrier make stream biochemical processor can near the center, pond, form eddy flow, thereby the fluidised form that makes full use of water body makes active sludge can carry out nitrification and denitrification fully, have good denitrification effect, reduce the generation of sludge quantity simultaneously greatly.The present invention has saved the water body treating investment greatly, have less investment, energy consumption is low, adaptability is strong, working cost is low advantage, the pond or the manmade landscape, artificial landscape's water body that are highly suitable for physical environment are used, eutrophication water there is good regulation effect, also can be used for handling low concentration waste water, therefore have promotional value.

Description of drawings

The present invention is further illustrated below in conjunction with accompanying drawing.

Embodiment

Embodiment one

The biochemical complex water body treating method of present embodiment may further comprise the steps as shown in Figure 1

A, in the pond, cultivate active sludge.Both can cultivate naturally, promptly utilize original microorganism self-reproduction cultivation in the pond, also can introduce required spawn culture.Usually keeping the volume of active sludge is that pond water volumetrical 5%-15% is advisable.

B, the anchor that falls along the border in the pond are settled one group of floating carrier spaced apart.Present embodiment adopts the chinampa filter bed as floating carrier.

This chinampa filter bed contains upper and lower two circle rigid border, upper and lower two circle rigid border connect by vertical web member, constitute three-dimensional frame, the rigid border layout is fixed with latticed water-fast cable, be fixed with radial fine material (being commonly called as environment-friendly filler) on the cable, fill floating material between the upper and lower two circle rigid border.Its concrete structure as shown in Figure 2, between the opposite side of stainless steel rigid border 1 with the fine material 3 of self band radiation nylon, be the nylon rope layout of brushing shape and become latticed (can buy on the market).During layout, vertically cable 5 and laterally cable 4 mutual interlacings.Determine the spacing of upper and lower stainless steel rigid border 1 according to the target plant kind, and fixing with the limit rope, and wherein the filling foamed plastics floating material 2.This chinampa filter bed is cost economy not only, and because rigid border is two-layer about being set to, relative fixed in the grid of layout played effect resistant to lodging about plant can rely on.
