Embodiment

[0021] In this embodiment, a certain eutrophic water area is used as the experimental area (the water area includes Lake A and Lake B, and the total water area capacity reaches 517,000 square meters), and a water pollution control system and a method for applying the system to control water pollution are provided. details as follows:

[0022] (1) Lake A

[0023] The area is 0.178km 2 , with an average water depth of 2.4m and a lake capacity of 427,000m 3 . The water quality of the lake is: COD10.8mg / L, TN20.18mg / L, TP1.06mg / L, NH3-N10.34mg / L.

[0024] 14 biofilters (also V-type filters can be used in other embodiments) are set by the lake, the size of each biofilter is 3.5m × 7.2m × 4.0m, and the filtration speed is 4.0m / h, 14 The total treatment capacity of each biofilter is 1200m 3 / h. Each biofilter is also correspondingly provided with a water pump, and the inlet of the water pump is connected with the lake A through a pipeline, and the water is delivered to the biof...

Abstract

The invention relates to the technical field of water body pollution abatement, in particular to a water body pollution abatement system and method. According to the method, a diversion wall and a plug-flow aeration machine are arranged in a water body, which have the effect of pushing water and aeration and prevent a dead water zone from being formed during water body circulation. A biological film net and an ecological floating island are arranged in the water body, certain dissolved oxygen gradient is formed at the bottom and the peripheral region of the ecological floating island under the photosynthesis of aquatic plants on the ecological floating island, and the dissolved oxygen gradient is beneficial to removing pollutants in the water body, such as N, P and the like, through the combined effect of aerobic bacteria, anoxic bacteria and anaerobic bacteria, so that the water quality is purified. Meanwhile, the plug-flow aeration machine is arranged in the water body, sufficient oxygen dissolved in the water body is guaranteed. The water body is firstly filtered through a filter chamber, a large proportion of organic matters and inorganic matters, such as suspended solids, algae and the like, in water can be removed, the filtered water flows into the water body again and forms water body circulation with the diversion wall arranged in the water body.

Description

technical field [0001] The invention relates to the technical field of water body pollution control, in particular to a water body pollution control system and method. Background technique [0002] According to the 2013 China Environmental Status Bulletin, the proportions of nationally controlled key lakes (reservoirs) with excellent water quality, light pollution, moderate pollution and heavy pollution are 60.7%, 26.2%, 1.6% and 11.5%, respectively. The indicators are total phosphorus, chemical oxygen demand and permanganate index. In the nationally controlled sections of the ten major river basins, including the Yangtze River, Yellow River, Pearl River, Songhua River, Huaihe River, Haihe River, Liaohe River, Zhejiang-Fujian Rivers, Northwest Rivers and Southwest Rivers, the water quality of Grade I-III, Grade IV-V and inferior to Grade V The proportions of sections are 71.7%, 19.3% and 9.0% respectively, and the main pollution indicators are chemical oxygen demand, perman...
