(1) By arranging the resource utilization device, the system integration is high

Sewage firstly enters the biological filler layer, the biological filler is a carrier of microorganism film, the biological filler has the advantages of large specific surface area, large void ratio, good hydrophilicity and the like, the biological film on the filler is uniformly distributed, obvious mud accumulation and agglomeration phenomena can not be generated, the treatment effect can not be influenced by the blockage of the biological film, and meanwhile, the microorganism is easy to attach due to the good hydrophilicity. Microorganisms on the surface of the packing layer can effectively reduce the concentration of pollutants in water and reduce the load of organic pollutants in the subsequent treatment process.

On the basis of biological filler purification, the coarse sand mainly utilizes the effects of physical adsorption, filtration and the like to effectively reduce the SS content in water. Meanwhile, microorganisms attached to the surface of the coarse sand further remove organic substances in water.

In soil, there are a large number of microorganisms in the roots and rhizosphere of plants, and there are complex interactions between these microorganisms and plants. The plants form carbohydrates through photosynthesis, then the carbohydrates are conveyed to roots, bacteria in the soil are provided by root systems, organic nutrients and energy which depend on survival are provided for rhizosphere microorganisms, and finally the activities of microorganisms and animals in the rhizosphere soil are improved. Soil microorganisms are the main decomposer of organic matters in soil and can also produce feedback effects on plants. The plant's fallen matter, secretion or plant dead stump and leaf and the organic fertilizer applied into soil are decomposed and released to produce nutritive elements for plant to utilize under the action of soil microbe to form humus for improving soil structure and fertility and benefiting plant growth.

The structural units are independent, interacted and mutually promoted to form a whole integrated system in space, so that the recycling effect of the domestic sewage is exerted to the best.

(2) Has obvious removing effect

When continuous water is discharged, on the basis of the sewage treatment effect of the traditional tri-format septic tank, the water quality purification effect is obviously improved by the synergistic purification effect of fillers, coarse sand, soil and plants in a longitudinal space, and the removal capacities of CODcr, ammonia nitrogen, total nitrogen and total phosphorus are respectively improved by 52.3% -65.7%, 48.2% -73.6%, 44.1% -56.8% and 57.1% -72.7%.

When water is intermittently or slightly fed, the sewage can be fully absorbed and utilized by vegetables.

(3) Low cost of investment, operation and maintenance

Has the obvious advantages of convenient installation, no leakage, good treatment effect, economic resource utilization and the like, and is especially suitable for rural areas and areas with imperfect matched facilities for scattered household sewage treatment. In addition, the device does not need to lay a large-scale sewage collection pipe network in the early stage of actual construction, and compared with the traditional mode of septic tank, pipeline conveying and tail end treatment, the construction investment cost is reduced by about 60% -70%. Meanwhile, no special person is required to be appointed to carry out operation and maintenance management on the whole system, and the operation and maintenance cost can be almost ignored.
