Integrated submersible photoelectromagnetism river and lake water purifying method and device thereof

Abstract

The invention relates to an integrated submersible photoelectromagnetism river and lake water purifying method and a device thereof. In the method, a sewage inhalation device, a gas-water mixer and a purifier which are successively connected are arranged at the bottom of a stream, a lake, an artificial lake, a fountain or a scenery fish pond. A water outlet of the purifier is arranged at a position near the water surface of the river and lake water; sewage water to be purified is inhaled by the sewage water inhalation device and is sprawled into the gas-water mixer in a jet flow way and at high speed after being magnetized strongly by a magnetizer; the sewage water in a gas mixing chamber of the gas-water mixer is forced to be mixed with ozone in the gas mixing chamber to compose a gas-liquid mixed flow; the mixed fluid is injected into the purifier; the high speed jet is utilized to involve and inhale sewage water near a water inlet of the purifier into the purifier; a photoelectric combined catalytic oxidation treatment is carried out on the sewage water mixed with the ozone in the purifier; then, outlet water forms a level circulating water flow on the periphery of the water outlet of the purifier to realize gradient exchange purification of the whole river and lake water. The integrated submersible photoelectromagnetism river and lake water purifying method and the device thereof have the advantages of less land occupation, little investment and operating cost and good purifying effect.

Description

technical field

[0001] The invention relates to the field of sewage treatment, in particular to the combination of photoelectricity and electromagnetics combined with strong oxidation, combined with aeration and oxygenation and artificial flow, which integrates a variety of processes into one to quickly treat rivers and lakes such as rivers, lakes, artificial lakes, fountains, and landscape fish ponds. A purification treatment method that removes organic pollutants such as COD, BOD, HS, and humus (humus is divided into four parts: humin, fulvic acid, humic acid, and Jimadomelonic acid), and can quickly eliminate bacteria and algae in river and lake water and devices. 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 t...

Examples

Embodiment 1

[0153] Example 1: Treatment of closed artificial lakes

[0154] 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:

[0155] 1. Geographical conditions of the lake:

[0156] 1) The lake water is black and smelly, with green algae and flowers, and the transparency is 0.3 meters;

[0157] 2) The water area of ​​rivers and lakes is 15,000 square meters, with an average depth of 1.4 meters;

[0158] 3) The artificial lake is fed by rainwater, and the pollution sources are chemical fertilizers, pesticides and humus;

[0159] 4) Fish often die;

[0160] 2. Water quality before treatment:

[0161] 1 color color black 2 Smelly Strong smell 3 Transparency, m≤ 0.3 4 pH value 6-9 5 Dissolved oxygen, mg / L 1-3 6 Chemical oxygen demand (COD)mg / L≥ 60 7 Biochemical Oxygen Demand, (BOD 5 )mg / L≥ 25 8 Ammonia nitrogen mg / L 6.5...

Embodiment 2

[0186] Example 2: River surge control of tributaries of rivers

[0187] 1. River geography and water quality:

[0188] 1.1. Geographic location

[0189] 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.

[0190] As the domestic sewage and industrial wastewater along the river rise with the tide and enter the B stream, where they stay...
