Phosphorus-containing nanofiltration concentrated water treatment equipment

Technical Field

The utility model relates to the technical field of sewage treatment, in particular to phosphorus-containing nanofiltration concentrated water treatment equipment.

Background

Concentrated water refers to wastewater, sewage and waste liquid produced in the industrial production process, and contains industrial production materials, intermediate products and products lost with water and pollutants produced in the production process.

In the prior art, concentrated water is preliminarily filtered and then is adsorbed by a filter material layer to treat and purify sewage, for example, in the prior published patent 202123135010.0, a novel total phosphorus adsorption water treatment device is disclosed, and the use method of the device is explained in paragraph 0026 of the specification, specifically, sewage is guided into a filter screen cylinder in a tank body through a water inlet pipe, a motor works to drive a stirring shaft and a stirring rod to rotate and stir the sewage continuously, so that the sewage impacts the filter screen cylinder continuously to avoid the blockage of the filter screen cylinder, impurities in the sewage are filtered by the filter screen cylinder, the filtered sewage flows into the tank body, and the impurities in the sewage are intercepted and fall into a sewage receiving hopper; the sewage flowing into the tank body enters the adsorption tank through the water permeable holes at the upper section, and total phosphorus in the sewage is adsorbed through a biological ceramsite filter material layer, a quartz sand filter material layer and a fiber ball filter material layer in the adsorption tank, so that suspended matters and oil stains in the water are removed, and the sewage is treated and purified; the treated sewage enters the bottom of the tank body through the water permeable hole at the lower end, and the valve is opened, so that the treated sewage can be discharged from the water outlet pipe.

As shown in fig. 1, which is a schematic structural diagram of the above-mentioned publication, fig. 4 is a dirt receiving hopper, fig. 3 is a filter screen cylinder, a stirring mechanism is composed of a motor 6, a stirring shaft 7 and a stirring rod 8, sewage enters the filter screen cylinder from a water inlet pipe, the stirring mechanism stirs the sewage to prevent the filter screen cylinder from being blocked, impurities in the sewage will fall into the dirt receiving hopper, at this time, the dirt receiving hopper and the filter screen cylinder are communicated, the sewage will flow into the dirt receiving hopper, and the disclosure does not describe that the bottom of the dirt receiving hopper is limited, the sewage will not leak from the dirt receiving hopper, so that the dirt receiving hopper is filled with the sewage, the impurities will float at the junction of the dirt receiving hopper and the filter screen cylinder, will not fall into the dirt receiving hopper, and possibly cause the filter screen cylinder to be blocked; even be equipped with the weeping hole in connecing dirty fill bottom, at the in-process of large tracts of land impurity accumulation gradually, the weeping hole also can lose original effect gradually to also can lead to impurity will float and connect the juncture of dirty fill and filter screen section of thick bamboo, can not drop to connect dirty fill in.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a dense water treatment facilities is received and strained to phosphorus has solved when handling sewage, and impurity deposits the shutoff on the filter screen and crosses filter mesh to cause the problem of filter screen section of thick bamboo jam.

In order to solve the above problem, the utility model discloses the technical scheme who adopts is: the phosphorus-containing nanofiltration concentrated water treatment equipment comprises a water inlet pipe, a water outlet pipe, a tank body and a tank cover fixedly mounted above the tank body through bolts, wherein the tank body is vertically arranged, the water inlet pipe comprises a main flow pipe and a flushing pipe, the main flow pipe and the flushing pipe vertically penetrate through a tank cover and extend into the tank body, and the lower end of the flushing pipe is communicated with at least two flushing branch pipes for flushing impurities deposited on a filtering funnel; the water outlet pipe is communicated with the middle part of the lower end of the tank body; the filter funnel is vertically fixed in the tank body and is positioned below the water inlet pipe, and the contact position of the filter funnel and the tank body is fixedly connected through a bolt.
