Description
Technical field
The utility model belongs to the environmental protection equipment technical field, is specifically related to the higher plant of a kind of purification efficiency-zoobenthos effluent treatment plant.
Background technology
Along with the continuous quickening of urbanization process, the nervous situation of Urban water supply has become universal phenomenon, and the municipal sewage treatment load increases day by day, handles the resource that back tail water becomes a kind of recyclable utilization.In many cities, sewage treatment plant tail water has become the main nourishment source of public landscape water body.Except that landscape water body, sewage treatment plant tail water mainly is back to river Hu Ku.
At present, even the tail water water quality of sewage work reaches the strictest one-level A standard, still have big gap from the minimum one-level V of natural water class water (agricultural water and general landscape water) standard.Generally speaking, so clear that you can see the bottom usually when sewage treatment plant tail water dispatches from the factory, transparency reaches more than 1.5 meters.When entering impounded body, behind pond, park or little reservoir, water body becomes brown or tawny very soon, the water transparency variation, and sensory effects is poor, and submerged plant more can't normal growth, and it is high to satisfy the natural water transparency, the water quality requirement of suitable pasture and water growth.
For improving the water landscape effect, prior art comprises chemical method, plant method, physics method three major types to the treatment process of sewage treatment plant tail water.The ultimate principle of chemical method is that part (as 10%) water is extracted out, and adds flocculation agent, makes phosphorus wherein drop to lower level, suppresses algal grown, reaches the effect of improving transparency.Shortcoming is high running cost (0.2-0.3 unit/m
3) become long-term burden.And can produce mud in the chemical method operational process, and must be transported to refuse landfill specially, also increased the public administration work load.The plant method is to utilize the emergent of plantation and nitrogen, phosphorus and the organic matter in pleuston and the rhizospheric microorganism absorption water body, reaches and reduces the water nutrition level, suppresses algal grown, improves the effect of water landscape.Plant method decontamination effect improving is limited, can only remove 20% pollutent, and water transparency also can only reach 0.5 meter.It is to avoid the water body blackout smelly that the physics method mainly acts on, and for fish guarantee life condition, weak point is that improvement, the purification of water quality effect to transparency is not obvious.In sum, press for a kind of tail water treatment technology that can satisfy low cost, high-level efficiency double technique effect of exploitation.
The utility model content
It is a kind of simple in structure that the purpose of the utility model is to provide, the plant that technology is easy-zoobenthos effluent treatment plant.
First purpose of the utility model is to realize like this; Comprise plant growing pond and zoobenthos pond; A described plant growing pond front end high position is provided with the tail water import; Rear end, a plant growing pond high position sets out the mouth of a river and is connected with the high-order water-in in zoobenthos pond, and rear end, a described zoobenthos pond high position is provided with clear water output; Described plant growing pond, zoobenthos pond reduce highly successively along water (flow) direction and are linked in sequence.
The sewage purification technology that the utility model adopts submerged plant and zoobenthos to cooperate has been realized the combination of plant water purifying device and zoobenthos purifier, and is simple in structure; Technical process is easy, and is stable, and implementation cost is low; Treatment effect is good, and need not to spend the operational management expense basically.The purifying treatment that can be used for sewage treatment plant tail water, effluent quality can be used as landscape water or directly enter the river course.
Description of drawings
Fig. 1 looks synoptic diagram for the utility model device configuration relation master.
Among the figure: the preposition plant of 1-pond, 2-zoobenthos pond, 3-thrust-augmenting nozzle.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described, but never in any form the utility model is limited,, all fall into the protection domain of the utility model based on any conversion that the utility model training centre is done.
As shown in the figure; The utility model comprises plant growing pond 1 and zoobenthos pond 2; Described plant growing pond 1 a front end high position is provided with the tail water import; Plant growing pond 1 a rear end high position sets out the mouth of a river and is connected with the high-order water-in in zoobenthos pond 2, and described zoobenthos pond 2 rear end high positions are provided with clear water output; Described plant growing pond 1, zoobenthos pond 2 reduce highly successively along water (flow) direction and are linked in sequence.
Described plant growing pond 1 and zoobenthos pond 2 are along the step setting of successively decreasing of water (flow) direction liquid level successively.
The water outlet in described plant growing pond 1 is than the low 0.3 ~ 0.6m of its water-in; Described zoobenthos pond 2 water-ins are than the low 0.2-0.4m of plant growing pond 1 liquid level; Described zoobenthos pond water outlet 2 is than the low 0.2-0.4m of its water-in liquid level.
Described plant growing pond 1 is divided into two-stage, along the step setting of successively decreasing of water (flow) direction liquid level successively; The prime water outlet in described plant growing pond 1 is than the low 0.3-0.6m of its water-in; The back level water outlet in described plant growing pond 1 is than the low 0.3-0.6m of prime water-in liquid level; Described zoobenthos pond 2 water-ins are the low 0.2-0.4m of back level plant growing pond 1 liquid level; Described zoobenthos pond water outlet is than the low 0.2-0.4m of its water-in liquid level.
