Using method of floating upper filtering type filter capable of cleaning by backflushing

Abstract

The present invention relates to a using method of a floating upper-filtering style filter with backwashing pollution-cleaning capability, belonging to the technique field of sewage disposal. A tank body is respectively welded with a manhole, a water outlet, a backwashing water inlet, a draining outlet and a water distributor, and the tank body is tightly fixed with a water filter and is connected with a vent flange and is embedded with a vision lens. The water outlet is connected with a water draining pipe through a water draining valve; the backwashing water inlet is connected with a water inlet pipe through a backwashing water inlet valve; the water inlet pipe is connected with the water distributor through a water inlet valve; a backwashing gas inlet is connected with a gas inlet pipe through a gas inlet valve; the draining outlet is connected with the filter body through a connecting valve, and the filter body is connected with a seal cylinder and the seal cylinder is connected with a draining pipe all through draining valve flanges; and the filter body is fixedly connected with a strainer film. The filtering material adopted in the method comprises polystyrene, pentane vesicant and cinnamene free monomer with a proportion less than 1. When in sewage disposal, the filtering materials are filled and draining is closed, and connection is done and gas is supplied, and then the water inlet valve is backwashed and the water draining valve and the inlet valve are opened; when pollutions cleaning, the water draining valve and the inlet valve are closed, and draining is opened and connection is done and the water inlet valve and the gas inlet valve are backwashed. The invention can be applied to sewage disposal, and the upper filtering filter occupies less space and the filtering materials have a long service life for pollution cleaning.

Description

technical field [0001] The method for using a floating upper-filter type filter capable of backflushing and cleaning pollution according to the present invention relates to the technical field of sewage treatment; in particular, it relates to the technical field of sewage treatment by means of filtration; in particular, it relates to an upper-filtering type sewage treatment technology capable of backflushing and cleaning pollution Field; specifically relates to the technical field of the use method of a floating upper filter type filter that can be recoiled and decontaminated. Background technique [0002] At present, whether it is sewage treatment devices / or equipment, or methods of sewage treatment, it can be said that there are many kinds of methods. As far as filter type sewage treatment devices / or equipment and the methods involved are concerned, all are down-filtering The equipment and method of this down-filtering type generally have many deficiencies, defects and dra...

[0002] At present, whether it is sewage treatment devices / or equipment, or methods of sewage treatment, it can be said that there are many kinds of methods. As far as filter type sewage treatment devices / or equipment and the methods involved are concerned, all are down-filtering The equipment and method of this down-filtering type generally have many deficiencies, defects and drawbacks such as large floor area, large investment costs, high operating costs, and poor comprehensive benefits; what is more prominent is that this existing known There are still problems in the technology that are all lower filter type and no upper filter type, the amount of sewage treatment is small and limited, the effect of sewage treatment is not ideal, the specific situation of sewage treatment cannot be observed, the service life of filter material is short, and the filter material It cannot be used repeatedly and many times, and the cleaning and treatment of the filter material is difficult and cumbersome, and many other shortcomings, defects and disadvantages
