Flow with meal kitchen sewage to prevent filler, and block the first water-permeable pipe 3 and the second water-permeable pipe 4, preferably, in the first water-permeable pipe 3 and the second water-permeable pipe 4, filtering net (not shown) is all set, prevent filler from flowing in the first water-permeable pipe 3 and the second water-permeable pipe 4 along with meal kitchen sewage, prevent the first water-permeable pipe 3 and the second water-permeable pipe 4 from blocking.
Preferably, filtering net is dismountable is installed on the first water-permeable pipe 3 and the second water-permeable pipe 4, facilitates routine cleaning and replacing.
The rough sand infiltrated in pond 5 to prevent rough sand excessively runs off or raw sewerage flows directly into rough sand and infiltrates pond 5, preferably, as depicted in figs. 1 and 2, infiltrate the opening end in pond 5 at rough sand to arrange rough sand and infiltrate Chi Gai, prevent rainwater or wind from being taken away by rough sand, prevent raw sewerage from polluting or blocking rough sand, in use for some time, replaceable rough sand, to keep the filtration efficiency of rough sand.
In order to prevent people or thing from falling in sewage collecting well 1 further by mistake, and reduce the vaporization loss amount of meal kitchen sewage, and prevent the smell of meal kitchen sewage from shedding, preferably, described sewage collecting well 1 is provided with well lid (not shown).
It should be noted that, the quantity of the size of reaction tank 2 and the planting density of moisture-proof herbaceous plant 23, the first permeable hole and the second permeable hole, specifically arrange according to the size of sewage collecting well 1.
In the present embodiment, sewage collecting well 1 for the degree of depth be 150-200cm, opening end diameter is 60-100cm, and base diameter is more than 120cm, and in the bottom of sewage collecting well sidewall 11, the even circumferential along sewage collecting well sidewall 11 arranges four first water-permeable pipes 3; On the top of reaction tank sidewall 24, and four second water-permeable pipes 4 are set along the even circumferential of reaction tank sidewall 24, wherein, the caliber of the first water-permeable pipe 3 and the second water-permeable pipe 4 is 8-12cm, and the first water-permeable pipe 3 is 15-20cm to the distance of the bottom of sewage collecting well 1, prevent mud from blocking the first water-permeable pipe, second water-permeable pipe 4 is 30-50cm to the distance of reaction tank 2 upper surface, when the water level of meal kitchen sewage is higher than the second water-permeable pipe 4, meal kitchen sewage process is just understood and is entered rough sand from the second water-permeable pipe 4 and infiltrate pond 5.
During use, sewage collecting well 1 is arranged near kitchen, sewer line directly will eat kitchen sewage discharge in sewage collecting well 1, when the water level of kitchen sewage of eating arrives the first water-permeable pipe 3, meal kitchen sewage will enter gravel bed 22 by the first water-permeable pipe 3, meal kitchen sewage filters through first in gravel bed 22, water level is higher than after geotextile 25, part meal kitchen sewage can by the Root Absorption of wet fastness herbaceous plant 23 prosperity, along with the further raising of water level, the meal kitchen sewage quantity that wet fastness herbaceous plant 23 absorbs process also can synchronously increase, and oxygen-starved area also constantly increases (oxygen-starved area maximum range is the region in reaction tank between the second water-permeable pipe to the first water-permeable pipe) simultaneously, before full water is not store in oxygen-starved area (before namely water level does not reach the second water-permeable pipe), meal kitchen sewage can not be discharged from reaction tank 2, meal kitchen sewage is enable for a long time denitrification to occur, reduce the nitrate nitrogen content in the sewage of meal kitchen to greatest extent.After water level is more than the second water-permeable pipe 4, the meal kitchen sewage processed can be discharged into rough sand gradually and infiltrate pond 5, after filtering through rough sand, flow into soil.Process like this, can reduce the nitrogen of 32-65% and the phosphorus of 65-79% in the sewage of meal kitchen, and reduces heavy metal, the pathogenic bacteria concentration in the sewage of meal kitchen, thus promotes water quality.
It should be noted that, the rough sand that fine sand layer, gravel bed and rough sand infiltrate in pond all can regularly or be changed according to practical situation.
In sum, meal kitchen provided by the invention waste disposal plant, the reaction tank comprising sewage collecting well and arrange around sewage collecting well, fine sand layer, geotextile and gravel bed is set gradually from top to bottom in reaction tank, plant in fine sand layer and be implanted with moisture-proof herbaceous plant, the bottom of sewage collecting well sidewall and sewage collecting well all adopts water-tight structure, prevents sewage from directly penetrating in soil, and only the first permeable hole is set at sewage collecting well sidewall, make sewage be discharged into gravel bed by fixed route, bottom and the reaction tank sidewall of reaction tank all adopt water-tight structure, and only on reaction tank sidewall and the position being positioned at described fine sand layer arranges the second permeable hole, meal kitchen sewage after process can be discharged from the second permeable hole, second permeable hole is higher than the first permeable hole, extend the residence time of sewage in reaction tank, enhancing fine sand and the herbal root system of moisture-proof are to the absorption of dirty water pollutant and assimilation effect, make as far as possible many sewage generation denitrifications, reduce the nitrate nitrogen content of sewage to greatest extent, realize concentrating process meal kitchen sewage effectively, alleviate meal kitchen sewage to destroy the pollution of edatope.
Last it is noted that above embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
