Embodiment 1

[0123] Example 1: Treatment of closed artificial lakes

[0124] Take the artificial lake of 20,800 cubic meters in a certain golf course as an example to illustrate this embodiment, and its treatment plan is as follows:

[0125] 1. Geographical conditions of the lake:

[0126] 1) The lake water is black and smelly, with green algae and flowers, and the transparency is 0.3 meters;

[0127] 2) The water area of ​​rivers and lakes is 15,000 square meters, with an average depth of 1.4 meters;

[0128] 3) The artificial lake is fed by rainwater, and the pollution sources are chemical fertilizers, pesticides and humus;

[0129] 4) Fish often die;

Embodiment 2

[0157] Example 2: River surge control of tributaries of rivers

[0158] 1. River geography and water quality:

[0159] 1.1. Geographic location

[0160] B Chung is located in the commercial center of a certain urban area. It is a famous landscape river in a certain urban area. The total length of the river is 1000 meters and the average width is 20 meters. Chung B is a newly opened river, and the revetment and greening projects have been completed. Weeping willows and banyan trees are planted on both sides of the river, forming weeping willows and green trees. It has both the scenery of the north and the unique cultural landscape of the south. B is a tidal surge, and its water level is affected by the river tide. There are two high tides and low tides every day, and the level difference between the rising and falling tides is about 0.6-1 meter.

[0161] As the domestic sewage and industrial wastewater along the river rise with the tide and enter the B stream, where they stay...

Abstract

The invention provides a water plant imitating biological carrier, a polyurethane composite material and a water quality purifying technology. The water plant imitating biological carrier comprises a multiple structure formed from a polyurethane layer, fiber web layers and fiber yarn layers, wherein the polyurethane layer is located in the inner layer; the two fiber web layers are respectively covered on the upper surface and the lower surface of the polyurethane layer; and the two fiber yarn layers are respectively covered on the external surface of the two fiber web layers. The polyurethane composite material contains 2-6 wt% of activated carbon fiber and 94-98 wt% of polyurethane. In the water quality purifying technology, submersible type photo-electro-magnetic river lake water quality purifying device is adopted with the water plant imitating type biological carrier to operate in the same area for water quality purification. When used for purifying bodies of surface water, the invention has the advantages of no land occupation by equipment, low investment cost and operating cost, high the removal efficiency on organic pollutants, and good application prospect, and the purification efficiency is more than 2 times greater than that of whole ecological restoration.

Description

technical field [0001] The invention belongs to the field of sewage and river and lake water treatment, and in particular relates to a biological carrier imitating aquatic plants, a composite material used for the carbon fiber layer of the biological carrier imitating aquatic plants, and a water purification process using the biological carrier imitating aquatic plants. Background technique [0002] With the rapid development of social economy, the industrialization and urbanization of human society are increasing day by day, and water pollution is becoming more and more serious. A lot of untreated sewage is directly discharged into rivers and lakes, causing rivers and lakes to gradually lose their self-purification ability, forming the first generation of water pollution represented by black odor and anoxic, or forming pollution represented by heavy metals and toxic chemicals. The second generation of water pollution, or the third generation of water pollution represented b...
