Treating method of heavy pollution river water

Abstract

The invention relates to a treating method of heavy pollution river water, and relates to the technical field of river water treatment processes. In the treating method, a machine body and a valve areincluded; a riverway is arranged inside the machine body; baffles are arranged at the upper ends of the two sides of the riverway; first inserting slots are inlaid inside the inner walls on two sidesof the riverway; a filtering plate is connected with the upper end of the inner side of the riverway; a water retaining gate is mounted inside the riverway; and a water inlet channel is fixedly arranged on the upper end of the right side of the riverway. The treating method has the beneficial effects that the baffles are arranged on two sides of the riverway, and are higher than the riverway, sothat sewage or water from other pollution sources, discharged industrially, can be effectively prevented from being intercepted and entering the riverway, meanwhile, household garbage on the machine body can be prevented from entering the riverway, and the baffles are directly inserted in the machine body, and can be pulled out from the machine body, so that the baffles can be selectively mounted,and are mounted at a position where industrial sewage is drained.

Description

technical field [0001] The invention relates to the technical field of river water treatment technology, in particular to a treatment method for heavily polluted river water. Background technique [0002] It is known that among the seven major water systems in my country, the Liaohe River and the Haihe River are heavily polluted, the Huaihe River, Songhua River, and the Yellow River are moderately polluted, and only the Yangtze River and the Pearl River have good overall water quality. The pollution of the river is more serious than that of the main stream. The main and tributary streams with a large population or industrial concentration near the coast are especially serious. Water pollution is developing from the east to the west, from the tributary to the main stream, from the city to the countryside, and from the surface to the underground. Infiltration, spreading from the region to the river basin, river water pollution poses a great threat to the development of human soc...

Problems solved by technology

[0004] The purpose of the present invention is to provide a treatment method for heavily polluted river water, to solve the in-situ biological enhancement treatment method for heavily polluted river water in villages and towns disclosed in the Chinese Invention Patent Application Publication Specification CN102863125A proposed in the above background technology. Although the in-situ biological enhancement treatment method for polluted river water passes through the water purification membrane filtration section, the concentratedly distributed sewage discharge nozzles are used as layout points to arrange high-efficiency water purification membranes to filter sewage according to 30% of the water area of ​​the section, and the water purification membranes can intercept Suspended matter and particles in the sewage, remove inorganic matter and some organic matter, and at the same time arrange a micro-nano bubble reoxygenation system in the middle of this section to treat a large number of planktonic algae, odor and other pollutants contained in the sewage, but the cost of the project is relatively high , takes a long time, and the water purification film will hinder the organisms in the water, affecting the normal life of the organisms
