Embodiment Construction

[0035] Combined with the preliminary research project of "Eryuan Miju River Water Environment Comprehensive Treatment Project" in Dali, Yunnan, the research on the Fengyu River non-point source pollution control side-by-side biological purification system was carried out in the Fengyu River in the upper reaches of the Erhai Lake. The plane layout of the purification system is shown in Figure 2. Fengyu River is the main supply water source for the upper reaches of Erhai Lake. Due to the pollution sources such as mountain soil erosion, village sewage, farmland non-point source, etc., the non-point source pollution of Fengyu River is currently serious, and the water quality has deteriorated significantly. After treatment, it will pollute the Miju River upstream of Erhai Lake and Erhai Lake. By adapting measures to local conditions and using the small (one) type reservoir located in the middle reaches of Fengyu River - Shangcun Reservoir, it will be transformed into a side-by-side...

Abstract

A biologic cleaning method for treating the water surface pollution of river features the water reservoirs and ponds nearby the polluted river are reformed to become a biologic cleaning system consisting of water retaining gate and water guide system, sand depositing system, water distributing and optimizing system, plant strengthened cleaning system, deep water cleaning system, water draining gate, and optimized running and management.

Description

technical field [0001] This method provides a method for transforming the existing reservoir or pond beside the river into a side-mounted biological purification system, and removes suspended solids, nitrogen, phosphorus, etc. The purpose of non-point source pollution, the method belongs to the technical field of water pollution control and ecological restoration. Background technique [0002] In recent years, with the increase of human activities, the vegetation in the upper reaches of many rivers has been severely damaged, resulting in soil erosion, pollution of villages on both sides of the river, and massive discharge of non-point source pollution from farmland, which has brought serious non-point source pollution to rivers. Rivers are direct importers of suspended solids, nutrients, nitrogen, and phosphorus in lakes. The increase in non-point source pollution in rivers makes it difficult for rivers to meet the needs of water environment functions, and increases the poll...
