Abstract

The sewage purifying plant facility consists of sewage collecting fermentation pond, water pipe, plant bed and water collecting ditches; and features the plant bed, which consists of water permeating blocks on two sides, filtering grit layer and earth layer between the blocks. There are plant on the earth layer, porous pipes in the filtering grit layer and connected to the fermented sewage source, water collecting ditches in the lower part of the plant bed and connected to the draining channel, gate and precipitating pond in the draining channel, and pump station to lift the initially treated sewage for conveying to the porous pipes of the next plant bed. The present invention can eliminate TN, TP, CODcr and BOD from sewage effectively.

Description

The device and method of sewage purifying plant

Technical field

The present invention relates to a kind of waste disposal plant and method, especially a kind of device and method of sewage purifying plant.

Background technology

Water is the precious resources that the mankind depend on for existence, constantly enlarge along with the suitability for industrialized production scale in recent years and the raising of people's living standard, industrial sewage and sanitary sewage amount are increasing, environmental pollution is more and more serious, people adopt physics at present, chemical process is purified waste water investment greatly, the running cost height, be difficult to generally use, cause many in, small business even part large enterprises industrial sewage directly are discharged into rivers and lakes, many cities and towns, especially the small town citizen sanitary sewage does not obtain any processing and directly is discharged into rivers and lakes, makes the available water resources deficient more.Begin one's study imitated natural ecosystem such as artificial swamp, land percolation technology of people in recent years, the overland flow technology waits to purify waste water and has obtained effect preferably, but above-mentioned technology is used and is subjected to restrictions such as geologic condition, edaphic condition, the sewage amount of confluxing on the one hand, on the other hand, wastewater treatment efficiency is difficult to control.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of investment and running cost low, wastewater purifying efficiency is good and can better beautify the environment, and improves the sewage purifying plant treatment unit and the method for natural condition.Purpose of the present invention realizes by following technical proposals: the inventive system comprises sewage and collect fermentation vat, hydraulic pipe (canal), plant bed, collecting gutter etc., plant bed sandstone filtering layer and dirt bed by permeable building block inboard, both sides constitutes, plant on the dirt bed and be implanted with landscape plant or trees, plant bed sandstone filtering layer surface or top are provided with orificed lateral, orificed lateral links to each other with fermentation back source of sewage, plant bed side lower part is provided with collecting gutter and links to each other with drainageway, drainageway is provided with gate and settling tank, the settling tank position is provided with pumping plant, makes to handle for the first time back sewage and can rise to and need be highly again export in the orificed lateral of next stage on plant bed by hydraulic pipe.Can establish three grades, level Four pumping plant even seven to eight grades of pumping plants in case of necessity, form the plant bed system of classification radiation-like.

Plant bed can be rectangle, circle, prismatic, and its permeable building block inboard is the sandstone filtering layer, and the centre is a dirt bed.

Said plant bed also can be in the middle of for the sandstone filtering layer, sandstone filtering layer both sides are dirt bed, dirt bed is outward permeable building block.

Position, aperture on the said orificed lateral is provided with retaining and penetrates plate, to prevent directly to wash away earth after water from penetrating.

Said hydraulic pipe also can be a canal for water conveyance, and the conveyance canal side is arranged with plant bed.

Treatment process of the present invention is as follows:

1, the separation of slag gas is carried out in elder generation's fermentation in fermentation vat behind the collection sewage after 3-7 days;

2, the sewage after the fermentation is transported in the orificed lateral on plant bed by the water delivery pipe duct;

3, sewage drips to be sprayed on behind the sandstone filtering layer by orificed lateral and carries out one-level by soil permeability for plant root whisker and absorb and handle;

4, sewage comes together in drainageway by collecting gutter after one-level is handled;

5, the sewage after by pumping plant on the drainageway one-level absorb being handled rises in the plant bed hydraulic pipe of next stage (canal) and carries out secondary and absorb and handle by the plant bed orificed lateral of going up in the second stage, by this method carry out three grades successively, that level Four directly causes last step is plant bed, the water after the processing directly discharges in rivers or the lake.

The present invention mainly utilizes fermentation vat that sewage is carried out fermentative processing, after organism decomposed and kill pathogenic bacteria, the biogas that produces is done combustion gas by pipe-line transportation and is used, waste residue is drawn out in the settling tank of fermentation vat one end, sewage is by pipe duct and hydraulic pipe, arm, be transported to plant bed going up through the diafiltration of sandstone filtering layer to dirt bed, and through collect by collecting gutter behind the root system of plant absorption cleaning and promote water level by pumping plant after plant bed through the second stage again, still to 3,4 grades of plant bed purifications, the water that gives off at last generally can reach sewage drainage standard.One aspect of the present invention utilizes the sandstone dirt bed to filter and the plant absorbing organism, and root system of plant discharges oxygen and kills the pathogenic bacteria material in matrix simultaneously, and the corresponding heavy metal thing etc. that neutralizes makes wastewater purifying efficiency very good, can remove TN, TP, COD _Cr, BOD ₅More than 80%, the present invention simultaneously has in the process of disposing of sewage and beautifies the appearance of the city preferably, the effect of improving the ecological environment.Orificed lateral of the present invention is located at sandstone filtering layer surface or top, can prevent effectively that plant root whisker from stopping up pore, the present invention can install the sewage transport order as required in operational process, promptly pressing the plant bed order of one, two, three, four within a certain period of time purifies, another section period purifies by four, three, two, one plant bed order, to reach the best purification effect, the present invention can effectively control wastewater purifying efficiency.

The present invention is applicable to city or lawn, sub-district, greenery patches, small town citizen district, medium-sized and small enterprises.The industrial park, artificial forest land and roadside greening district.
