Abstract

A method and apparatus for clarifying wastewater containing solid and/or fibrous materials is described in which the incoming wastewater stream containing the solid or fibrous materials is aerated. The aerated incoming stream is conveyed to and through a separation vessel 6 having a baffle arrangement 12 where it is evenly distributed by the baffle arrangement 12 to allow the wastewater stream to be de-aerated. As the incoming wastewater stream de-aerates by passage through the baffle arrangement 12 the contamination of solids and fibre material is floated to the surface of the wastewater by the rising air or gas bubbles floating to the top of the separation vessel 6. In one embodiment the baffle arrangement 12 includes three substantially circular baffle plates 16, 18 and 20 arranged in partially overlying spaced apart relationship to define a tortuous flow path through which the aerated wastewater flows to assist in facilitating release of the gas or air from the wastewater to float the solid/fibrous materials to the top of the treatment vessel 6 where it is removed as a sludge or foam. The flowpath is such that two different zones are formed, one being a quiescent zone of substantially clarified wastewater and the other being a turbid zone containing fibre/solids material where no eddy currents or similar are produced to mix the two zones at their interface. In one example the sludge/foam or similar is further treated in a hydro-cyclone defoamer 60 or similar vessel.

It can be set in Qiying 14 in the separation tank 6 and in the tank 6 Between the top flow grooves, low or high velocities' and low or two back pressures are produced. The introduced mixed gas waste water flow is adjusted so that there will be two areas formed or close to the bottom of the separation tank with an interface 28. One of these areas is the A area referred to in the first figure, which is located under the surface 28. It is a clean liquid area that contains almost no pollutants such as particles or fibrous substances contained in the wastewater stream; and the other The area, which is located above the interface 28, is the area “B, as shown in FIG. 1, which is a contaminated liquid area containing particles or fibrous matter” and an area containing rising air or gas bubbles with solid / fiber. Note that the area B extends from the interface 28 to the liquid level at the top of the separation tank 6 where the opening 32 is located. Before being introduced into the tank 6, the fine air bubbles generated when the wastewater is mixed with gas can contain particles or fibrous substances contained in the bubbles, so when the bubbles float towards the top surface of the polluted area B During the rise, the solid or fiber particles will similarly float to the top surface of the tank 6 to separate the substances from the wastewater.
