Floating type temporary in-situ purification device for sewage draining exits of riverway

Abstract

The invention relates to a floating type temporary in-situ purification device for sewage draining exits of a riverway. The floating type temporary in-situ purification device comprises a solar aeration system, a buoyancy system, an aquatic plant system, a floating bed framework supporting system, a combined filler system and a floating type water purification barrier system, wherein the solar aeration system is arranged on the buoyancy system; the buoyancy system, the combined filler system and the aquatic plant system are arranged in the floating bed framework supporting system; the floating type water purification barrier system is arranged below the floating bed framework supporting system. By the adoption of an in-situ ecological purification technology, the device can effectively remove organic pollutants and nutritional salt such as ammonia nitrogen which are discharged from the sewage draining exits and also can efficiently remove SS. The device does not need a piling fixing device; a floating type water purification barrier floats up and down according to a water level change and can effectively prevent rain wash; by the adoption of a solar system for aeration, no electricity is needed, so that the operation cost is low, the occupied area is small, the investment cost is low, and the dismounting and movement are facilitated; the floating type temporary in-situ purification device is applicable to in-situ temporary purification treatment for the scatteredly dispersed sewage draining exits of the riverway.

Description

technical field [0001] The invention relates to the field of black and odorous river treatment and sewage purification, in particular to a floating temporary in-situ purification device for sewage outlets of rivers, belonging to the technical field of environmental engineering. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, the problem of river water pollution has become increasingly prominent. There have been many black and smelly rivers in the country. However, in some areas, the sewage interception and management plan of sewage outlets lags behind the black and odorous river improvement plan, and many sewage outlets cannot be solved temporarily. Problems to be solved urgently in the management of black and odorous rivers. [0003] The treatment methods for river sewage outlets mainly include flower bed type purification tanks, sewage outlet purification tanks, and in-situ purification c...

Problems solved by technology

[0002] With the rapid development of the economy and the continuous improvement of people's living standards, the problem of river water pollution has become increasingly prominent. There have been many black and smelly rivers in the country. However, in some areas, the sewage interception and management plan of sewage outlets lags behind the black and odorous river improvement plan, and many sewage outlets cannot be solved temporarily. Problems to be solved urgently in the treatment of black and smelly rivers

[0003] The treatment methods for river sewage outlets mainly include flower bed type purification tanks, sewage outlet purification tanks, and in-situ purification corridors. Among them, flower bed type purification tanks build sump pools in the river, and pump the discharged domestic sewage to the shore for treatment. The investment cost is high, and the space along the river needs to be occupied. Some rivers have existing buildings along the river, and there is no space available. Therefore, it is difficult to use this method for construction; the purification tank of the sewage outlet is built with a constructed wetland treatment tank at the sewage outlet in the river, covering an area of Large, need regular mud discharge, difficult to manage
