Example Embodiment

[0036] Example 1: The pollution control methods of the eutrophic water body of Dianchi Lake are as follows:

[0037] 1. Overview

[0038] (1) Dianchi Lake: Under the normal high water level (1887.4m) of Dianchi Lake, the water area of ​​Dianchi Lake is 309.6km 2 , The total storage capacity is 1.56 billion m 3 In the north, it is divided into two parts: Caohai in the north and Waihai in the south. Caohai area 7.3km 2 (Excluding the two separated water bodies: Dongfeng Dam and Laogan Fish Pond), which accounts for 3.5% of the area of ​​Dianchi Lake, with a water storage capacity of 22.58 million m 3 , 1.5% of the total storage capacity of Dianchi Lake. The outlet of Caohai Sea is an artificial tunnel—Xiyuan Tunnel, with a water exchange period of about 3.5 months; the outlet of the open sea is the Haikou Zhongtan Gate, which is discharged into the Tanglangchuan, with a water exchange period of about 3 years; between Caohai and the open sea The water body cannot be exchanged free...

[0066] Example 2: The pollution control methods of eutrophic water bodies in the suburbs of cities are as follows:

[0067] 1. Overview

[0068] Calculated in large and medium-sized cities: population of 500,000 to 1 million, per capita water consumption quota is 200L / d. The water supply is 0.365-73 billion cubic meters per year. It is assumed that the amount of supplemental water is related to the amount of water taken. The quality of supplementary water is divided into I, II, and III. The quality of the polluted water source used is The water storage capacity is 300 million cubic meters, and the water change cycle is 6 years.

[0069] 2. The pollution control method of this eutrophic water body (influent water quality is Class IV), the design scale is 100,000 m 3 / d (Meet the water consumption of 500,000 people), the specific operation is as follows:

[0070] (1) At room temperature, feed the eutrophic water body water from the upper part of the biological filter evenly t...

[0088] Example 3: The pollution control methods of eutrophic water bodies in the suburbs of cities are as follows:

[0089] 1. Overview

[0090] Calculated as a medium-sized city: the population is 500,000, and the per capita water consumption quota is 200L / d. It is assumed that the amount of supplemental water is related to the amount of water taken. The quality of supplementary water is divided into I, II, and III. The quality of the polluted water source used is The water storage capacity is 300 million cubic meters, and the water change cycle is 6 years.

[0091] 2. The pollution control method of this eutrophic water body (influent water quality is Class IV), the design scale is 100,000 m 3 / d (Meet the water consumption of 500,000 people), the specific operation is as follows

[0092] (1) At room temperature, feed the water from Dianchi Lake from the upper part of the biological filter evenly through the filter layer, and the water is discharged from the bottom, and th...

Abstract

The invention discloses a pollution control method for an urban suburb eutrophication water body. According to the method, the eutrophication water body is used as a life drinking water source, in addition, the original water source is used as supplementing water of the eutrophication water body, the original water plant water purification process is improved so that the eutrophication water body is used as urban drinking water after being purified, and in addition, the pollution government cost is put into practice onto a pollution discharge main body or customers in a water supply charge form of a water plant. The method has the advantages that the traditional water pollution control concept is changed, the cyclic utilization of water resources is realized through the organic coupling of the pollution discharge main body and the responsibility main body of the water pollution government, meanwhile, the water change period of the eutrophication water body can be shortened by the method, in addition, the water quality of the supplemented water is good, the concentration dilution speed of nutrients in the pollution water body is favorably accelerated, and the pollution control of the urban suburb eutrophication water body is finally realized.

Description

technical field [0001] The invention relates to a pollution control method for eutrophic water bodies in the suburbs of cities, and belongs to the field of restoration of polluted water bodies in the suburbs of cities. Background technique [0002] Eutrophication of water body refers to that under the influence of human activities, a large amount of nutrients such as nitrogen and phosphorus required by organisms enter slow-flowing water bodies such as lakes, estuaries, and bays, causing algae and other plankton to multiply rapidly, and the dissolved oxygen in water bodies decreases. Deterioration of water quality, massive death of fish and other organisms. Since the eutrophication of water bodies is caused by the nutrients discharged by human activities, the water bodies in the suburbs of cities, as the receiving water bodies of human activities, are more prone to eutrophication and the degree is particularly serious. At present, water eutrophication has become one of the m...
