Abstract

The utility model discloses a city black and smelly riverway treatment facility which comprises a garbage grid and a geotextile arranged on the upper course of the riverway to be treated, and a garbage grid and a geotextile arranged on the lower course of the riverway to be treated; the garbage grids and the geotextiles are orderly arranged along the water flow direction; a biochemistry buffering area is formed between the garbage grid of the upper course and the geotextile of the lower course; an aeration device is arranged in the biochemistry buffering area. Compared with the traditional treatment facilities, the utility model has the advantages that the black and smelly environment of the riverway can be eliminated in a short time; the effect is rapid and obvious because sludge in the riverway does not need to clean; various microbes of natural environment can automatically degrade the sludge in the riverway gradually; the sludge need not to be stopped to recover the inherent self-cleaning capability of the riverway, etc.

Description

Smelly river regulation facility is deceived in the city

(1) technical field:

The utility model relates to a kind of treatment facility of river course, particularly the treatment facility in black smelly river course, a kind of city of severe contamination.

(2) background technology:

It is open that city river mostly is greatly, and the main source of pollution of river have two classes, and a class is the sewage that enters the river course, another kind of for be discharged into the pollutent the river from bed mud, the bed mud in general river course is thicker, and contains a large amount of pollutents in the bed mud, as organic matter, nitrogen, phosphorus etc.And the improvement in black smelly river course, existing city, mainly based on physics methods such as desilting and section dirts, desilting promptly utilizes the gate in river course or manually does the cofferdam, with the river course closed at both ends, river is drained the back to adopt the method for machinery that mud is cleaned out again; Cut dirt and be the source of pollution that to enter the river course processing of damming.There is following shortcoming in existing river regulation method: 1, the quantities of channel cleanout is big, and the cycle is long, engineering cost is high; 2, to cut the difficulty of dirty management big in pollution of river source, can't implement in a short time; 3, be difficult to behind the water correction keep, because open river course is difficult to stop to control pollutent and enters, after improvement for some time, the river course is black gradually again smelly, and forms new polluted bed mud gradually.

(3) utility model content:

At the problems referred to above, it is a kind of without desilting, section dirty black smelly river regulation facility in city that also can recover river course inherent self-purification capacity that the purpose of this utility model is to provide.

For achieving the above object, technical solution of the present utility model is:

Smelly river regulation facility is deceived in a kind of city, comprise and be arranged at rubbish grid, the geotextile of waiting to administer the upstream, river course, and be arranged at rubbish grid, the geotextile in this downstream, pending river course, described rubbish grid, geotextile set gradually along water (flow) direction, between the geotextile in the rubbish grid of described upstream and downstream, form biochemical buffer zone, in this biochemistry buffer zone, be provided with aerator.

Ball float all is installed on the described geotextile.

Described aerator is oxygenating machine or diving oxygenating machine.

Because comprising, the utility model is arranged at rubbish grid, the geotextile of waiting to administer the upstream and downstream, river course, between the geotextile in the rubbish grid of described upstream and downstream, form biochemical buffer zone, rubbish grid, geotextile can be tackled suspended substance big in the river and floating matter, guaranteeing that the equipment in the pending section normally moves, and the buffering river is treated the quality of river water of treatment zone and the impact load of the water yield; In addition, owing in biochemical buffer zone, be provided with aerating apparatus, after river is carried out pre-treatment, biochemical buffer zone can be the physical environment microorganism provides normal growing environment, utilize aerobic in the buffer zone, double oxygen, the absorption degradation ability of various physical environment microorganisms such as anaerobism is eliminated black smelly, reduce the concentration of water pollutant, make the concentration of pollution of river thing reach running balance, recover the self-purification capacity in river course, and the aerator in the river course also has the plug-flow effect, can increase the flowability of river and the effect of air reaeration, form the balance environment that a following current promotes.Therefore, the utility model is compared with traditional treatment facility, have and can eliminate the black smelly of river course in the short period of time, effect is got instant result, the river course is without desilting, multiple physical environment microorganism can degrade voluntarily gradually riverway sludge, need not cut dirt, can recover advantages such as river course inherent self-purification capacity.Owing on the geotextile ball float is installed, geotextile can be adjusted height and obliquity automatically according to the variation of the river water level and the water yield, and it is unimpeded to be beneficial to streamflow.

(4) description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of geotextile.

(5) embodiment:

Smelly river regulation facility is deceived in a kind of city of the utility model, as shown in Figure 1, the black smelly river regulation facility in the utility model city comprises along water (flow) direction and is set in turn in the rubbish grid 1 of waiting to administer the upstream, river course, geotextile 2, and be arranged at the rubbish grid 3 in this downstream, pending river course, geotextile 4, between rubbish grid 1 and geotextile 4, form biochemical buffer zone 5, this biochemistry buffer zone 5 is about 30 meters, in this biochemistry buffer zone 5, be provided with aerator 6, this aerator 6 can be selected oxygenating machine and diving oxygenating machine etc., described geotextile 2 for use, ball float 7 all is installed on 4.

In governance process, rubbish grid, geotextile are normally moved suspended substance big in the river and floating matter interception to guarantee the equipment of waiting to administer in the section; Because dissolved oxygen content is very low in the black smelly river course, city, open 6 a few days of aerator earlier, the dissolved oxygen content in river course is reached more than the 1mg/l, subsequently, the physical environment microorganism begins a large amount of breedings, and black smelly river course can produce in 1 month obviously and improve, the color of water body becomes grey by black earlier, become normal light green by grey again, the stink in river course also can be eliminated in a few days, and the transparency of river also can obviously improve.Because river bottom mud organic content height, natural microorganisms is in decomposing river in the pollutent, utilize the Degradation of anaerobion, bed mud is also effectively degraded, so just can fundamentally prevent because pollutants in sediments discharges the pollution of estuary that causes, recover the self-purification function of water body, keep the water quality in river course for a long time.

In addition, general open river course, city all has the function of flood discharge in rainy season concurrently, for guaranteeing the unimpeded of river course between storm period, ball float 7 is installed on

geotextile

2 and 4, as shown in Figure 2,

geotextile

2,4 can be adjusted height and obliquity automatically according to the variation of the river water level and the water yield like this, and it is unimpeded to be beneficial to streamflow.

The utility model construction is simple, less investment, effect are got instant result, and can be kept the water quality in river course for a long time.
