Water-entering adaptive adjusting sewage outfall device

Abstract

The invention discloses a self-adaptive adjustment pollutant-discharge port device for entering the water body, comprising a float pool, a fixed pier, an anchoring bar, a floating drum, a flexible soft connection pipe, a connector, a sewage inlet pipe, and a sewage outlet pipe; the float pool is arranged beside a bank, the middle and the lower parts of one side of a pool wall that is near a riverbed is provided with a through groove, and the width of the groove is matched with the pipe diameter of the sewage outlet pipe; the number of the fixed piers is two, the piers are respectively arranged on the bottom of the pool; the anchoring bar is fixedly connected on the fixed pier and extends vertically onto the top of the float pool; the floating drum is actively connected on the anchoring bar via the casing rings at the two sides; the flexible soft connection pipe is connected between the sewage inlet pipe and the sewage outlet pipe; the sewage inlet pipe is connected with a pollutant-discharge pipe or is connected with an open channel via an aggradation pool; the sewage outlet pipe is connected with the floating drum via the connector, and the water outlet end is arranged in the flowing water body. The sewage outlet pipe of the invention can move upward and downward with the change of water level, thus making the discharged sewage be at the optimal waterpower intersection position, diffuse and transport rapidly, and avoiding the problem of re-pollution.

Description

Technical field [0001] The invention belongs to the technical field of sewage discharge devices for environmental water conservancy projects, and in particular relates to a self-adaptive adjustment sewage outlet device designed based on the water flow characteristics of the river confluence area. Background technique [0002] With the continuous deepening of people’s understanding of water environmental pollution, as well as the sustainable development requirements of controlling water pollution and protecting water quality, domestic and foreign has gradually formed the treatment of industrial wastewater and domestic sewage, and then enter the river through various modes of sewage discharge. , Lakes, canals, channels, reservoirs and oceans. Or according to the requirements of environmental standards in different regions, pollutant concentration indicators or total indicators, or indicators required by both of them, are used to control the discharge of sewage. According to the co...

Problems solved by technology

[0004] The purpose of the present invention is to aim at the defects of the existing fixed sewage outlets, and provide a device for self-adaptively adjusting the sewage outlets entering the water body. This device can not only prevent sewage from entering the river from the air, but also make better use of water Features Diffusion and transport of pollutants to avoid the problem of re-pollution caused by the accumulation of sewage in the confluence and return areas
