Described water collecting basin, organic composite soil water purification unit and outlet sump all can be set to several according to sewage disposal demand, organic composite soil water purification unit also can be set to two-stage or multistage, can be divided into two or more connected organic composite soil water purification unit and at least one is connected with outlet sump.
Preferably, on the pipeline of described water collecting basin and organic composite soil water purification unit, be provided with transferpump, to overcome the transporting resistance causing due to physical features and to improve transport efficiency.
Preferably, the other end of described outlet sump is by being communicated with organic composite soil water purification unit with the pipeline of transferpump, with to COD higher water outlet carry out circular treatment, further lifting waste water treatment effect.
Organic composite soil water purification unit in the utility model, adopt the mode of alternation of wetting and drying, be divided into four cycles that can loop: water inlet is oozed soon phase, retaining and oozed slowly the phase, oozes deep purifying phase and vacant decubation slowly, sewage, can be fast, stable and purify efficiently and reach emission level under soil, microorganism and herbal acting in conjunction.
The beneficial effects of the utility model are:
1, can control water inlet and water distribution according to sewage discharge rule, general farm sanitary sewage after first class purification water outlet can be up to standard direct outer row, can consider to carry out organic soil purification more than two-stage to the town sewage of water quality relative complex.
2, floor space is little, and anti impulsion load is high, adopts ripe earth working material, short construction period, and cost is low, and initial cost is few, and can increase economic benefit by kind of plant.
3, Personnel Skill Levels is required low, maintenance management is convenient, and power consumption is little, and operation cost is low, during water inlet, earth's surface is dry state, sanitary condition is good, and is conducive to cultivated land protection because of a large amount of original soils that adopt.
