Description
Technical field
The utility model relates to a kind of device of handling micro-polluted water.
Technical background
Conventional water treatment process can effectively be removed suspended substance and the colloidalmaterial in the former water, but can not effectively remove organic pollutant and chemical disinfection byproducts.In the face of constantly increasing the weight of of pollution of waterhead, particularly form the organic compound of mutagen and haloform and can be impelled people to research and develop the novel process of removing this compounds by the existence of microorganism as the solubility organic compound of carbon source.Absorption method can effectively be removed dissolved organic matter in the water, becomes one of effective measure in the water treatment.
Pulverous wilkinite has good adsorption treatment effect to the organic micro-polluted water that contains solubility, but because wilkinite is a kind of Powdered clay, swelling easily taking place behind the water logging bubble, form the mud of dispersion suspension, causes solid-liquid separation very difficult.At present a lot of solid-liquid separation adopt coagulating sedimentation or sand filtration technology.Coagulating sedimentation need add chemical agent, and processing cost causes secondary pollution easily than higher; And adopt sand filtration technology, and to stop up easily, back flushing is difficulty relatively, and effluent quality is poor.And absorption be separated in different processing units in carry out respectively, increased floor space greatly, the less water treatment plant of the scale that therefore is not suitable for uses.
Summary of the invention
The purpose of this utility model is to provide a kind of compact construction, the device of the close-coupled processing micro-polluted water of fractionation by adsorption that processing efficiency is higher.
The device of the close-coupled processing micro-polluted water of fractionation by adsorption of the present utility model, it is characterized in that it mainly comprises slop pail, the precoating bucket, pump, pre-filming filter and air compressor, water inlet pipe is arranged at the bottom of pre-filming filter, the top is provided with rising pipe and tensimeter, has the filter element that surrounds by filter screen of being separated by in the pre-filming filter with housing, the bottom of filter element is connected to water pipe and ventpipe, the water-in of pump also is connected to two water inlet pipes, the water outlet of pump also is connected to two rising pipes, the outlet of precoating bucket links to each other with a water inlet pipe of pump through first valve, a rising pipe of pump links to each other through the water inlet pipe of second valve with the pre-filming filter bottom, the rising pipe at pre-filming filter top is connected through the import of the 3rd valve with the precoating bucket, slop pail has water outlet, water outlet links to each other with another water inlet pipe of pump through the 4th valve, the water pipe of filter element bottom divides two the tunnel, wherein one the tunnel is connected with the import of slop pail through the 5th valve and under meter, another Lu Jingdi six valves link to each other with another rising pipe of pump, and ventpipe communicates with air compressor.
During this device work, at first in the precoating bucket, add diatomite (diatomaceous particle diameter is the 5-30 micron), open first valve, second valve and the 3rd valve, the circulated pre-coating system that is formed by precoating bucket, pump and pre-filming filter begins the precoating that circulates, and forming thick on filter element is the diatomite filtration layer of 1-5 millimeter.In slop pail, add wilkinite (80-200 purpose powder) then, micro-polluted water is mixed the suspension that forms with pulverous wilkinite, switch valve, first valve and the 3rd valve are closed, the 4th valve and the 5th opening of valves, at this moment slop pail, pump and pre-filming filter form circulated filter system, after suspension pumps into pre-filming filter, enter filter element through scribbling diatomaceous filtering layer, flow out from the water pipe of filter element bottom, be back to slop pail through pipeline and carry out the integrated circular treatment of fractionation by adsorption, the organism in the micro-polluted water is constantly adsorbed by wilkinite, and wilkinite is held back by the diatomite pre-coating film, continuous increase falls in the pressure of the inside and outside both sides of filter element, if the pressure when concentration of suspension is zero in the recirculated water is reduced to filtering ultimate value, when falling in pressure, the value of reaching capacity shows that solid-liquid separation finishes, stop filtration.Utilize the pressurized air blowback,, close second valve again, open the 6th valve, use the less water back flushing amassing the filter cake stripping that diatomite on the pre-filming filter filter element and wilkinite form.The micro-polluted water processing finishes, and discharges clear water, begins the integrated cycle of fractionation by adsorption of a new round again.
The utility model combines bentonitic high efficiency of additive capability and celatom pre-coating filter technology, because diatomite can form on the filter element surface and be easy to by the filtration precoating rete of stripping, the effectively catching bentonite suspension, thus successful solution absorption method solid-liquid separation difficult technologies difficult problem when handling in the micro-polluted water dissolved organic matter.The utility model apparatus structure is compact simple, can realize absorption and solid-liquid separation process integration are carried out simultaneously at a treatment unit, reduce floor space, and the precoating repeatedly of diatomite pre-coating film, wilkinite original soil and diatomite are cheap and easy to get, the processing efficiency height.Test shows that permanganate index is that water outlet dropped to 3.2mg/L after the former water of 6.8mg/L was handled through the fractionation by adsorption integrated technique.Micro-polluted water can reach the drinking water source water quality standard fully after the utility model device is handled.The utility model is fit to small-sized water treatment plant to be used.
