Problems solved by technology

Since the above-mentioned water pollution accidents have the characteristics of uncertainty in time, place, and pollutants, and strong suddenness, it is difficult to prevent them. If they cannot be dealt with in time, they will often cause different degrees of pollution spread and social impact.
At present, sewage is usually treated by biological and chemical methods. The facilities are bulky, cumbersome, and lack mobility. Moreover, it takes a long time for commissioning when the facilities are put into operation. All have great uncertainty, sudden and strong water pollution accidents
Therefore, there is currently no method and device that can promptly and effectively deal with sudden water pollution accidents with great uncertainty in time, place, and pollutants.
[0007] Whether it is possible to use an emergency method and a highly mobile water treatment device to transport the water treatment device and supporting facilities to the scene of the water pollution accident in the shortest possible time after the occurrence of the water pollution accident, so as to timely and effectively treat the pollution Treatment and purification of water bodies, rapid control and elimination of pollution, and reduction of the social impact of pollution accidents have not been reported so far

Embodiment 1

[0073] The sudden water pollution accident handled by this embodiment is the pollution of the river waters near the factory caused by the leakage of pollutants from a chemical factory, causing the chemical oxygen demand (CODCr), total mercury, total cadmium, chromium (hexavalent), and total Lead, total cyanide, and volatile phenol indicators seriously exceeded the standard. Adopt the present invention to carry out emergency treatment to polluted waters, the method and device of emergency treatment are made up of water intake part, water treatment part and logistics support part, comprise: two water pump trailers 8, twenty-five water treatment equipment trailers 22, two water pump trailers Processing equipment support trailer 24, a monitoring trailer 26, a regeneration device trailer 38, an oil tank trailer 42, a material trailer 45, a catering trailer 48, and two sleeper trailers 57.

[0074] The water intake part is composed of a metal cage 1, a bottom valve 2, a buoy 3, an a...

Embodiment 2

[0099] The sudden water pollution accident dealt with in this embodiment is a lake with eutrophication as a source of urban water. The monitoring data shows that the nitrogen, phosphorus, and chlorophyll a contents in the water seriously exceed the standard, and the temperature of the lake exceeds 20 degrees Celsius due to the weather. The water level is higher than normal years, but the water level is lower than normal years. The higher water temperature and lower water level lead to further deterioration of water quality. The water supply is safe. The present invention is used for emergency treatment of algae-rich water in the waters near the water source. The emergency treatment method and device are composed of a water intake part, a water treatment part and a logistics support part, including: three water pump trailers 8, thirty-eight water pump trailers Treatment equipment trailer 22, two water treatment equipment bracket trailers 24, one monitoring trailer 26, one regen...

Abstract

The invention discloses an emergency treatment device for water pollution accidents, which comprises a water taking part and a water treatment part, wherein the water taking part consists of a water pump trailer and a substance trailer, the inside of the water pump trailer is provided with a sewage pump, and the sewage pump is connected with an electric control cabinet; the substance trailer is dispersedly equipped with rubber water pipes; a water inlet of the sewage pump is connected with the rubber water pipes, and a water outlet of the sewage pump is connected with the water treatment part;and the water treatment part arranges an activated coke absorption device on a trailer, and a water inlet of the activated coke absorption device is connected with the water outlet of the sewage pumpof the water taking part. The rubber water pipes connected with the water inlet of the sewage pump on the water pump trailer are placed into sewage, the sewage pump is started to convey the sewage into the activated coke absorption device arranged on the trailer for sewage treatment, and treated water is drained from a water outlet of the activated coke absorption device.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a treatment method and device for sudden water pollution accidents Background technique [0002] During the production process of the enterprise, due to production accidents and other reasons, the chemical or pollutants of the enterprise leak into the rivers, reservoirs, lakes and other waters around the factory area, resulting in the pollution of the water bodies of the above-mentioned rivers, reservoirs, lakes and other waters. [0003] During the operation of the water treatment enterprise, due to the failure of the sewage treatment facilities, the discharge outside the enterprise exceeded the standard, causing water pollution in the rivers, reservoirs, lakes and other waters around the factory area. [0004] During the transportation of chemicals, due to traffic accidents or other reasons, chemicals leak into the surrounding rivers, reservoirs, lakes and ...
