Abstract

The utility model discloses a concentric circular platform type domestic sewage processing and recycling device, which comprises a plurality of concentric annular concrete walls, wherein the diameters of the concrete walls are increased gradually in sequence, and the heights of upper edges of the concrete walls are reduced gradually in sequence, the intermost circle of concrete wall is internally provided with multiple layers of filtration packing, a sewage inlet pipe directly enters the bottom layer of the multiple layers of filtration packing, and the packing in the intermediate circles of concrete walls is soil; and the internal part of the outmost circle of concrete wall serves as a recycled water reservoir, and is provided with a recycled water outlet pipe. The concentric circular platform type domestic sewage processing and recycling device disclosed by the utility model can process and recycle domestic sewage so as to realize the aim that one family or many families uses one set of concentric circular platform type domestic sewage processing and recycling device. The concentric circular platform type domestic sewage processing and recycling device has the advantages of multifunction, short low, rapid speed, favorable water quality, large concentration ratio, low cost and low energy consumption, and moreover, the recycled water after sewage process can be used for irrigation so as to save fertilizer and fresh water resources.

Description

A kind of coaxial round platform sanitary sewage disposal and recycle device

Technical field

The utility model belongs to sewage recycle utilization field, relates to a kind of coaxial round platform sanitary sewage disposal and recycle device.

Background technology

Widespread pollution from the overuse of fertilizers and pesticides in rural area is topmost one type of non-point pollution; Mainly be meant all contaminations matter that in the agriculture prodn activity, produces; In precipitation or irrigation process, through farmland rainwash, farmland drainage and underground leakage, make a large amount of pollution substances get into water bodys and the pollution that causes.Domestic sewage in rural areas by using is one of topmost pollution source in the widespread pollution from the overuse of fertilizers and pesticides in rural area.The domestic sewage in rural areas by using staple has nitrogen, phosphorus, organic matter, LAS, pathogenic bacteria etc., and wherein some material is the nutritive element useful to plant like nitrogen, phosphorus, can important nutrient be provided for plant-growth, and organic matter can be increase soil fertility and the level of the productive forces.Yet, excessive nutrient, organic matter, also some other material may exert an influence to edatope and plant growth.Therefore, the processing of domestic sewage in rural areas by using being carried out to a certain degree is very important.The rural development of current recycling economy type is an important development trend of rural society sustainable economic development, reuses such as based on recycling economy visual angle, rural area, the reuse water after domestic sewage in rural areas by using is handled can be used as and flushes the toilet, carwash, irrigation.

Along with becoming increasingly conspicuous of Freshwater resources imbalance between supply and demand, adding water source for irrigation also becomes various countries' solution water resources crisis question of common concern.Reclaimed water for irrigation can avoid utilizing sewage directly to irrigate caused serious pollution of area source problem on the one hand, and for plant-growth provides important nutrient, increases soil fertility and the level of the productive forces thereby increase the soil organism.On the other hand, excessive nutrient, toxic chemical substance and the pathogenic agent while input environment ecosystem also can cause environmental pollution to a certain degree in the reuse water, might endanger environment and human health.

Summary of the invention

The utility model provides a kind of coaxial round platform sanitary sewage disposal and recycle device, and sewage is efficiently handled and can be carried out the reuse of multiple purpose simultaneously, and is simple, cost is low, energy consumption is low.

The technical scheme that the utility model adopts is; A kind of coaxial round platform sanitary sewage disposal and recycle device comprise the ring-like concrete walls of a plurality of coaxial circles, and the diameter of each concrete walls successively from small to large; Concrete walls upper edge height successively from high to low; Be provided with the bed filtration filler in the concrete walls of inner ring, sewage water inlet pipe directly feeds among the bed filtration filler lower floor, and the filler in the several concrete walls of intermediary in the circle is pedosphere; As reuse water deposition water reservoir, be provided with the reuse water rising pipe in the concrete walls of outmost turns.

The device of the utility model; Adopt coaxial round platform sanitary sewage disposal and recycle apparatus processes and reuse sewage; Realize a family one cover or a few family one cover; Purposes is many, flow process is short, speed is fast, water quality is good, concentration ratio is big, cost is low, energy consumption is low, and the intact reuse water of WWT is irrigated also and can be saved chemical fertilizer and Freshwater resources, has broad application prospects.

Description of drawings

Fig. 1 is the structural representation of the utility model device.

Among the figure, 1. sewage water inlet pipe, 2. waterplant, 3. pedosphere, 4. hybrid filtering layer, 5. large gravel bed, 6. reuse water rising pipe;

In addition, A, B, C, D are respectively four circular ring type concrete walls from inside to outside.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.

Like Fig. 1; The coaxial round platform sanitary sewage disposal and the recycle apparatus structure of the utility model are; Comprise four ring-like concrete walls A of coaxial circles, B, C, D, the diameter of concrete walls A, B, C, D successively from small to large, concrete walls upper edge height is successively from high to low; Be provided with the bed filtration filler among the concrete walls A of inner ring; Be followed successively by large gravel bed 5, hybrid filtering layer 4 (being mixed by little gravel-coal dust ash-slag), pedosphere 3 from top to bottom, sewage water inlet pipe 1 directly feeds among the large gravel bed 5, on pedosphere 3, can plant corresponding waterplant 2; Filler in concrete walls B and the concrete walls C in the circle is kind of the pedosphere 3 that waterplant 2 is arranged; Do not put filler in the concrete walls D of outmost turns,, be provided with reuse water rising pipe 6, be used to discharge the reuse water after the filtration as reuse water deposition water reservoir.

Above-mentioned concrete walls can be provided with 3-6 circle, the diameter of each concrete walls successively from small to large, concrete walls upper edge height is provided with successively from high to low.

The utility model principle of work is; Sewage is by in the bed filtration filler in the most inboard concrete walls of water inlet pipe 1 entering; Water from bottom to top moves, and passes through large gravel bed 5, hybrid filtering layer 4 and pedosphere 3 successively, upwards permeates from level to level and flows out to the outer ring; Successively degrade through modes such as filling adsorption among concrete walls B and the C or plant absorbing; The reuse water of finally handling stores at the deposition water reservoir that outermost layer concrete walls D surrounds, and is used for utilizing once more through rising pipe 6, or gets into other bigger water reservoirs as required in order to other purposes.

Embodiment: concrete walls A from inside to outside, B, C, D diameter are respectively: 1.0m, 1.8m, 2.4m, 3.0m; Highly be respectively: 0.4m, 0.7m, 1.0m, 1.3m.Concrete walls A bottom large gravel bed 5 thickness are 0.3m, and hybrid filtering layer 4 thickness above the large gravel bed 5 are 0.5m, and the superiors are that pedosphere 3 thickness are 0.5m.

The device of the utility model; Propose with a kind of coaxial round platform sanitary sewage disposal and recycle apparatus processes and reuse sewage; Purposes is many, flow process is short, speed is fast, water quality is good, concentration ratio is big, cost is low, energy consumption is low, and the intact reuse water of WWT is irrigated also and can be saved chemical fertilizer and Freshwater resources.
