Description

Rainwater grate cut dirty facility

Technical Field

The utility model relates to a water environment improvement field, concretely relates to rainwater grate cut dirty facility.

Background

Recently, the phenomenon of black and odorous river channels in China is serious, and sponge cities are propelled rapidly, wherein initial rainwater interception and remediation are involved. Present initial stage rainwater is held back and is renovated mainly including setting up the vatch basin, setting up regulation pond etc. these are terminal renovation measures, have more drawback and not enough, because it is located whole drainage system's end, when the rainwater converges at different times of converging, the definition of initial stage rainwater is comparatively fuzzy to bring and hold back multiple value problem etc.. In addition, the later maintenance difficulty of the regulation and storage tank is higher, and the cost is higher. Therefore, a pollution interception measure for solving the problem of initial rainwater from the source is urgently needed.

SUMMERY OF THE UTILITY MODEL

The utility model provides a rainwater grate intercept dirty facility to the solution initial stage rainwater that solves prior art existence intercepts dirty problem of handling and leading to the maintenance degree of difficulty big in regulation pond later stage through the filtration of front end.

In order to solve the technical problem, the utility model provides a rainwater grate intercept dirty facility, including rainwater grate, rainwater side ditch, separator, filter layer, be provided with separator and filter layer in the current rainwater side ditch, the rainwater grate is located rainwater side ditch top, the separator is located the top of filter layer.

Preferably, the work flow of the sewage intercepting facility of the rainwater grate is as follows: rainwater gets into the separator, and the reposition of redundant personnel is realized to the rainwater, and suspended solid is detained in both sides in the rainwater, and clear stream gets into the filter layer, and the filter layer carries out secondary purification to the rainwater again, gets rid of the heavy metal ion of the inside, and final rainwater gets into rainwater side ditch and realizes discharging.

Preferably, the water passing capacity of the rainwater grate, the separator and the filter layer is not lower than the design standard.

Preferably, the rainwater grate can intercept large sundries, the separator can effectively retain suspended matters, and the filtering layer can effectively remove metal ions.

The utility model discloses the beneficial effect who brings:

(1) the utility model has simple structure, compact design and convenient installation;

(2) the utility model discloses compare in traditional rainwater grate, can reduce the pollution of suspended solid in the rainwater, the maintenance cost is low.

FIG. 1 is a schematic view of the whole structure of a rainwater grate;

wherein, 1-rain water grate, 2-rain water side ditch, 3-separator and 4-filter layer.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to specific embodiments.

As shown in figure 1, the utility model discloses the implementation provides a rainwater grate's dirty facility of intercepting, including rainwater grate 1, rainwater gutter 2, separator 3, filter layer 4, its characterized in that, be provided with separator 3 and filter layer 4 in the current rainwater gutter 2, the rainwater grate is located rainwater gutter 2 top, the separator is located the top of filter layer.

Further, the work flow of the sewage intercepting facility of the rainwater grate is as follows: rainwater gets into separator 3, and the reposition of redundant personnel is realized to the rainwater, and suspended solid is detained in both sides in the rainwater, and clear stream gets into filter layer 4, and filter layer 4 carries out the secondary purification to the rainwater again, gets rid of the heavy metal ion of the inside, and final rainwater gets into rainwater gutter 2 and realizes discharging.

Further, the water passing capacity of the rainwater grate 1, the separator 3 and the filter layer 4 is not lower than the design standard.

Further, the rainwater grate 1 can intercept large impurities, the separator 3 can effectively retain suspended matters, and the filter layer 4 can effectively remove metal ions.

To sum up, the utility model discloses simple structure, the design is compact, simple to operate compares in traditional rainwater grate, can reduce the pollution of suspended solid in the rainwater, and the maintenance cost is low.

It should be noted that, the utility model discloses the multiple standard component that uses all can be obtained from the market, and nonstandard component then can customize very much, the utility model discloses the connected mode that adopts such as bolted connection, welding etc. also are very common means in the mechanical field, and the inventor is no longer repeated here.

The above description is only an example of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
