Description

Vertical flow device for water treatment channel

According to the present invention, in a water treatment channel such as an artificial wetland, a water treatment channel type reactor, a connection channel between water treatment facilities, and an ecological channel, the treated water flow in the upper portion of the water channel and the treated water flow in the lower layer are, of course, pressurized or separated. An upper and lower alternating current device that can be replaced without a pumping system. A pair of inclined transverse plates, which are installed symmetrically with respect to the center line of the channel at the top and the bottom of the channel, respectively, and are symmetrically installed on each other. Consists of a pair of triangular flat plate connecting the bottom of the cross plate and the top of the lower inclined cross section plate to enable quick and easy construction.

In water treatment techniques such as artificial wetland, ecological treatment using ecological waterway, and advanced biochemical treatment, waterway-type treatment tanks such as connecting waterways or reactors for each stage of wetland or reactor, and aquatic plants are planted or microorganisms are inoculated. In this ecological waterway, the treatment water flow in the upper part of the water channel and the treatment water flow in the lower layer can be replaced with each other to improve the water treatment efficiency.

This flow of the upper and lower flows of the water channel is a variety of water treatment such as homogenizing effect of the distribution of microorganisms and contaminants through gradual agitation and increasing the nutrient removal efficiency by exchanging the aerobic environment in the upper layer and the sub-anaerobic environment in the lower layer. The performance improvement effect will be expressed.

Interchange of the upper and lower flows of the channel can be basically carried out by means of the upper and lower sorting of the channel, and transfer through the pump and bypass channel, but this requires complicated attachments and facilities, The need for power, bar power up and down AC channel 10 as shown in Figures 1 and 2 has been developed to effectively exchange the upper and lower flow in the channel 10 without a separate bypass or pumping means It became.

In the conventional AC channel 10 as shown in FIGS. 1 and 2, the flow alteration plate 11, which is a plate body twisted 180 degrees around a center line, is installed inside the channel 10 to provide a total flow cross section of the channel 10. In the maintained state, the flow of the upper layer and the lower layer of the channel 10 are interchanged.

As shown in FIGS. 1 and 2, the conventional vertical flow channel 10 to which the flow change plate 11 is applied has a twist formed on a plate having a width greater than that of the channel 10, and then precisely cuts the channel. (10) To be precisely bonded to the inside, not only the construction is very complicated, but in the case of large-scale facilities, there was a problem that is practically impossible to apply.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and in the upper and lower alternating current devices for replacing the treated water flow in the upper layer and the treated water flow in the lower layer, each of the upper and lower portions of the channel 10 in the water treatment channel 10 A pair of inclined transverse plates 21 arranged diagonally across (10) but symmetrically with respect to the center line of the waterway 10, and the lower inclined transverse plates 21 at the lower side and the lower inclined transverse plates 21 at the lower side. It is an up and down alternating current device for water treatment waterway, characterized in that consisting of a pair of triangular flat plate (22a) connecting the top.

In addition, a water treatment channel comprising a plurality of frame modules 23 having a triangular prism shape in which all five surfaces are open, and a triangular flat plate 22b and a wall plate 24 attached to the surfaces of the frame modules 23. It is a top and bottom AC device.

Through the present invention, a simple and quick construction of the up and down alternating current channel is possible, and thus the effect of improving the water treatment efficiency by applying the non-powered up and down alternating water channel to various types of water treatment facilities.

The detailed configuration of the present invention through the accompanying drawings as follows.

First, Figure 3 is a perspective view showing a representative embodiment of the present invention, Figure 4 is a rear perspective view of the embodiment, as can be seen through the drawings the present invention is a waterway (top and bottom of the channel 10, respectively) 10) obliquely traversed 10, but a pair of inclined transverse plate 21 which is installed symmetrically with respect to the center line center line, and the lower inclined transverse plate 21 of the upper side and the inclined transverse plate 21 of the lower side It consists of a pair of triangular flat plate 22a connecting the top.

That is, the upper inclined transverse plate 21 and the lower inclined transverse plate 21 are installed diagonally across the planar channel 10, the lower end of the lower inclined transverse plate 21 is in contact with the bottom surface of the channel 10, the upper side The upper end of the inclined transverse plate 21 is located at the upper end of the waterway 10, the lower center of the upper inclined transverse plate 21 is located at the upper center of the lower inclined transverse plate 21, X pair of plates of the same shape It has a structure stacked on it.
