Embodiment 1

[0019] As shown in Figure 1, the decentralized sewage purification method includes the following steps: After the domestic sewage enters the pool body by gravity through the open ditch, under the guidance of the enclosure, it first enters the purification area of ​​the bionic water grass filler, and the organic matter is mainly removed in the purification area of ​​the bionic aquatic grass filler and ammonia nitrogen, and then enter the submerged plant purification area. After the plant absorbs nitrogen and phosphorus, part of the tail water is pumped into the high-level water tank on the high-level rockery through the return pump installed in the submerged plant purification area, and returns to the bionic after falling. Aquatic grass filling purification area, another part of the tail water is discharged.

[0020] As shown in Figure 1, the decentralized sewage purification facility includes an ecological pond unit and a return unit. The ecological pond is a baffle structure,...

Embodiment 2

[0024] As shown in Figure 1, the decentralized sewage purification method includes the following steps: after the domestic sewage enters the pond by gravity through the pipeline, under the guidance of the enclosure, it passes through the purification area of ​​bionic aquatic plants and the purification area of ​​submerged plants in sequence, and part of the tail water passes through The return pump installed in the purification area of ​​submerged plants returns to the drop platform, and then returns to the purification area of ​​the floating belt packing after falling, and the other part of the tail water is discharged.

[0025] As shown in Figure 1, the decentralized sewage purification facility includes an ecological pond unit and a return unit. The ecological pond is a baffle structure, and the pond is divided into a bionic aquatic plant filler purification area and a plant purification area by using soft enclosures. The two areas are connected in series. Soft curtain-like ...

Abstract

The dispersed in-site ecological sewage purifying process belongs to the field of sewage treating technology. Pond in countryside used as sewage treating apparatus is separated with water separating barricading into a purifying stuffing zone and a purifying plant zone. In the purifying stuffing zone, bionic water weed stuffing is set; and in the purifying plant zone, submergent plant is planted. Under the guide of the barricading, sewage is made to pass through the purifying stuffing zone and the purifying plant zone successively, so that organic matters and trophic salts are eliminated. The treated water is returned with a reflux pump to aerate and raise the treating effects of purifying water, beautifying environment and preventing water eutrophication.

Description

technical field [0001] The invention relates to an economical and effective decentralized sewage treatment method, which is especially suitable for on-site treatment of sewage in relatively scattered residential areas such as villages, sanatoriums, tourist resorts, etc., and is also suitable for the treatment and restoration of landscape water bodies such as tourist areas and gardens. Background technique [0002] In recent years, with the development of society and economy, environmental problems have become increasingly prominent, and the requirements for sewage treatment are getting higher and higher not only in cities, but also in rural areas. The domestic sewage in scattered rural areas carries a large amount of nitrogen, phosphorus, organic matter and other pollutants into the water body, which makes the water body face the danger of serious eutrophication. In addition, with the increasingly serious situation of water resources, there are more and more requirements for...
