Embodiment 1

[0036] A treatment method for black and odorous water, the method comprises the steps of:

[0037] Step 1, turn over the bottom mud of black and smelly water, mix the water body with the bottom mud, and form a mud-water mixing area in the water, so that N and P in the bottom mud can be transferred to the water medium, preferably, in the mud-water mixing area Aeration treatment enables the water body to undergo preliminary oxidation and purification treatment in the mud-water mixing area, which greatly reduces the treatment time of the water body in the biological aeration filter. At the same time, the air bubbles generated during aeration can accelerate the splitting of the sediment and promote N, P transferred to the water body;

[0038] Step 2, extract the muddy water in the muddy water mixing area, send the extracted muddy water into the grill room, and use the filter method of intercepting the bottom mud between the grilles and passing through the water to separate the mud...

Embodiment 2

[0042] Such as figure 1Shown is a ship-borne equipment for treating black and odorous water bodies. The ship-borne equipment includes: a hull 2, the hull 2 ​​travels in the river channel 1, and processes the passing waters. Of course, multiple ships can also be equipped depending on the width of the river channel 1. Hulls 2 work together in the river channel 1 side by side, and an aeration turning machine 3 is arranged at the tail of the hull 2, and the aeration turning machine 3 is to increase the aeration function on the basis of the existing turning machine, such as: in the turning machine The rotary shaft of the rotary shaft is set as a hollow shaft, the inner cavity of the rotary shaft is an air supply channel, and an aeration hole is arranged on the rotary shaft, and the gas is sent into the inner cavity of the rotary shaft by the aeration machine room 14, and aeration is performed through the aeration holes; or, An aeration head or other aeration devices are added to th...

Abstract

The invention discloses a treatment method for black foul water. The method comprises the steps: (1) overturning bottom sludge of the black foul water so as to form a sludge-water mixed area; (2) pumping muddy water of the sludge-water mixed area, and separating pumped bottom sludge from water; (3) adding a solidifying agent into the bottom sludge separated out in the step (2), carrying out stirring and mixing, solidifying N and P in the bottom sludge, and returning the solidified bottom sludge to a river; and (4) carrying out purifying treatment on the water separated out in the step (2), and returning the purified water to the river. The invention further discloses shipborne equipment for treating the black foul water.

Description

technical field [0001] The invention relates to the field of black and odorous water treatment, in particular to a treatment method for black and odorous water, and a shipboard device capable of treating black and odorous water. Background technique [0002] In recent years, the economy of various parts of our country has developed rapidly, but there are still problems of insufficient supervision and supervision in terms of environmental protection. Excessive discharges and illegal discharges have occurred from time to time, causing ecological damage to rivers and environmental pollution, and the formation of black and odorous water bodies has become a relatively common problem. Phenomenon. [0003] The "Water Pollution Prevention Action Plan" issued by my country clearly proposes to intensify efforts to solve the problem of black and odorous water bodies. The control of black and odorous water bodies is related to the national economy and the people's livelihood, and is an...
