Embodiment Construction

[0024] Attached below figure 1 , 2 The content of the present invention is further described.

[0025] A kind of hydro-oxygenation ecological algae removal boat, comprising a double-boat boat 8 and a hydro-power oxygenation algae removal equipment arranged on the double-boat boat 8, the hydropower oxygenation ecological algae removal equipment consists of 24 to 48 hydraulic boosters It is composed of oxygen algae removal unit and secondary sedimentation tank. The hydraulic oxygenation and algae removal unit is set on the secondary sedimentation tank, which is divided into 4 to 6 layers. The hydraulic oxygenation and algae removal units on each layer are arranged in 2 rows in the horizontal direction and 2 to 4 in the vertical direction. Arranged in rows, the hydropower aeration and algae removal unit on the top floor is provided with a water inlet pipe, which is connected to the submersible pump 6 located in the water;

[0026] The outside of the secondary settling tank is p...

Abstract

The invention discloses a hydraulic aerobic biological algae removal boat which comprises a two-bateau ship and a hydraulic aerobic algae removal device arranged on the two-bateau ship. The hydraulic aerobic biological algae removal device which comprises 24-48 hydraulic aerobic algae removal units and a secondary sedimentation tank on which the hydraulic aerobic algae removal units are arranged, the upmost layer of the hydraulic aerobic algae removal unit is provided with a water intake pipe which is connected with a submersible pump arranged in water, a drainpipe is arranged at the outer side of the secondary sedimentation tank and connected with a diffuser, each hydraulic aerobic algae removal unit comprises a water tank, filling and a negative pressure generator, a water intake region is arranged at one end of the water tank, the filling is arranged between the inhalant region and the negative pressure generator, a water sucking mouth of the negative pressure generator is arranged in a position 25 mm from the bottom of the water tank in the hydraulic aerobic algae removal unit, a drainage outlet of the negative pressure generator is arranged a water intake region at the other end of the next layer of the hydraulic aerobic algae removal unit, and a drainage outlet of the negative pressure generator of the undermost layer of the hydraulic aerobic algae removal unit is arranged in the secondary sedimentation tank.

Description

technical field [0001] The invention relates to a water treatment method, in particular to a device for removing cyanobacteria and eutrophication from polluted water, and belongs to the technical fields of water environment ecological restoration and sewage treatment. Background technique [0002] At present, there are two types of deep treatment of polluted water bodies at home and abroad. One is to introduce and apply sewage biological treatment technology to treat it in depth. When the treatment reaches the first-class A standard, the operating cost has reached 2 yuan. / m 3 So far, there is no example of treatment reaching Class III of surface water; the other is to use special treatment methods, such as molecular sieves, nanometers, etc., and its operating costs are 1 to 2 times higher than biological treatment. All the popular sewage biological treatment processes today need to use blast aeration or other various aeration methods to increase the dissolved oxygen in the...
