Embodiment Construction

[0012] In one embodiment of the present invention, the sewage river treatment method is applied at the mouth of the river.

[0013] Such as figure 1 As shown, a sluice is set at the mouth of the river, and a water pump is set in front of the sluice. The number of water pumps can be one or more. The water pump is equipped with an automatic control pumping system, which continuously pumps water from the river 24 hours a day and discharges it to the sea side , its total pumping flow is slightly greater than the required daily sewage discharge, so that the water in the river is always at the lowest level.

[0014] Since there is no seawater intrusion phenomenon, after the water level of the river bed is significantly lowered, the black and smelly phenomenon of the river water will be significantly improved if the principle of flowing water does not rot. When the flood comes, the gate is opened to release the water without affecting the flood discharge.

[0015] The method of the...

Abstract

The invention discloses a process for treating river sewage comprising, arranging a gate at the convergence of the river and its entrance for preventing sea water encroachment, installing a water pump in front of the gate (on the river side) for pumping the water from the river to discharge to the sea side so as to lower the water level of the river bed. The process provided by the invention can prevent the salt-water encroachment and improve the river condition substantially.

Description

technical field [0001] The invention relates to the field of environmental protection engineering, in particular to a sewage river treatment method. Background technique [0002] The phenomenon of black and odorous rivers is a common problem in cities, especially in more developed cities. There are many reasons for the black and smelly rivers. It is generally agreed that the main source of the black and smelly rivers is the pollution of domestic sewage and industrial sewage flowing into the river. The existing sewage river treatment method is mainly realized by reducing the discharge of pollution sources by diverting rain and sewage. The investment is large, the project is complicated, and the effect is not significant enough. Contents of the invention [0003] The purpose of the present invention is to solve the problems of large investment, complex engineering and insufficient effect in existing sewage river treatment methods, and provide a simple sewage river treatment...
