Embodiment 1

[0017] The decentralized sewage purification method includes the following steps: after the domestic sewage enters the pool body through the open ditch, under the guidance of the enclosure, it first enters the purification area of ​​the bionic aquatic plant filler, in which the organic matter and ammonia nitrogen are mainly removed, and then enters the bionic aquatic plant filler purification area. In the submerged plant purification area, after the plants absorb 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 aquatic plant filler purification area after falling. Part of the tail water is discharged.

[0018] The decentralized sewage purification facility includes an ecological pond unit and a backflow unit. The ecological pond is a baffle structure, and the pond body is divided into a bionic water plant filler...

Embodiment 2

[0022] The decentralized sewage purification method includes the following steps: after the domestic sewage enters the pond by self-flow through the pipeline, under the guidance of the enclosure, it passes through the bionic aquatic plant filler purification area and the submerged plant purification area in sequence, and a part of the tail water is purified through the submerged plant. The return pump in the area returns to the water drop platform, and then returns to the purification area of ​​the floating belt packing after falling water, and the other part of the tail water is discharged.

[0023] The decentralized sewage purification facility includes an ecological pond unit and a backflow 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 bionic fillers are added to the filler purificatio...

Abstract

The invention provides an in-situ ecologic purification method for decentralized waste water. A soft enclosure is arranged in an existing pond to form a two-stage type strengthened ecologic pond with a packing purifying region and a submerged plant purifying region, an in-situ purifying ecologic pond system is established by a powered drop water oxygenating circulating facility, and the in-situ ecologic purification method for decentralized waste water comprises the following specific steps: A, establishing an enclosure in a region where the decentralized waste water joins in a natural pond, and dividing the pond into a packing purifying region and a submerged plant purifying region; B, feeding bionic aquatic plant packing in the packing purifying region of a region where the decentralized waste water joins in, and planting submerged plants in the submerged plant purifying region of a region where the decentralized waste water flows out; and C, establishing a waterfall type drop water artificial hill at a starting end of the region where the waste water joins in, returning part of drained water to the artificial hill by a submerged pump, and enabling the water to flow backwards and enter a water feeding region through waterfall type drop water.

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] 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 the reuse of sew...
