Description

A sewage physical treatment device

technical field

The utility model belongs to the technical field of sewage treatment and relates to a sewage physical treatment device.

Background technique

With the economic development and the strengthening of environmental protection awareness, the urban sewage treatment business continues to develop, and the total water treatment volume and treatment degree of sewage plants continue to expand and improve. The sewage treatment process generally includes physical, chemical or biological methods in sequence. The physical process is to separate and recycle the suspended pollutants in the sewage, and the chemical process is to separate and recycle the dissolved pollutants in the sewage through chemical reaction and mass transfer. , Pollutants in colloidal state, and transform them into harmless substances.

When treating sewage, first of all, physical methods should be used to remove visible impurities such as floating and suspended solids in sewage. Commonly used methods include sedimentation tanks, centrifugal separation, grids, screens, etc., but these methods have the following disadvantages: sedimentation The pond method occupies a large area, requires a large investment in civil construction, and takes a long time; the centrifugal separation method has the disadvantages of high energy consumption and high cost; the removal effect of the grid and screen is poor.

In order to solve the shortcomings of large area, low efficiency and high energy consumption in the physical removal of impurities in existing sewage treatment, the utility model provides a sewage treatment device with a new structure.

Contents of the invention

The purpose of the utility model is to provide a sewage treatment device in order to solve the problems of large occupied area, low efficiency and high energy consumption existing when using physical methods to treat sewage.

The utility model is achieved through the following technical solutions:

A sewage treatment device, comprising a water inlet pipe, an inner tank, a diversion tank, and an outer tank, the bottom of the outer tank is provided with a drain, and the inner tank is fixed above the cavity of the outer tank; the inner tank of the inner tank is fixed There is a sedimentation tank, the end of the water inlet pipe is fixed directly above the sedimentation tank, and the bottom outside the inner tank is provided with a water receiving tray; the upper part of the two sides of the diversion tank is a zigzag structure, which is horizontally arranged between the water receiving tray and the Between the outer tanks, one end is welded on the water receiving tray, and the other end is welded on the inner wall of the outer tank; the cavity of the outer tank at the lower part of the diversion tank is respectively provided with an upper filter layer and a lower filter layer from top to bottom .

Further, the sedimentation tank is a bottom discharge sedimentation tank, with an open upper end, a movable bottom plate for sealing the bottom, a lock on the bottom plate, and a matching lock on the inner tank, when the sedimentation tank is full , open the bottom plate to remove the sludge in the sedimentation box.

There are 6 diversion grooves, which are evenly fixed on the outer circumference of the water receiving tray.

The outer tank wall on the upper part of the upper filter layer is provided with a drain port equipped with a valve. After the system has been running for a period of time, the drain port at the bottom of the outer tank pumps, such as cleaning fluid, to backwash the two filter layers and open The valve discharges the flushed water from the drain port to ensure the continuous operation of the system and high-efficiency filtration.

The upper and lower filter layers are detachable. When the filter layer is fully loaded, the filter layer can be disassembled and cleaned to ensure the high efficiency of system filtration.

The utility model is suitable for the treatment of sewage that removes impurities through preliminary precipitation. The sewage slowly flows into the sedimentation tank through the water inlet pipe. When the sedimentation tank is full of sewage, the sewage overflows to the inner tank. After the inner tank is full of sewage, the sewage overflows Drain tray, in this process, the impurities in the sedimentation tank will be more and more, the sewage overflowing into the inner tank has already deposited part of the particles in the sedimentation tank, and when it overflows from the inner tank to the water accumulation tray, the water in the inner tank A part of impurities was deposited at the bottom, and the sewage in the water accumulation pan slowly flowed into the water guide groove, and then overflowed from the sawtooth structure to the outer tank. The two layers of filter layers in the tank again perform physical filtration and adsorption on the sewage, and the sewage filtered through the five layers of sedimentation is finally sent to the next treatment procedure from the outlet at the bottom of the outer tank for treatment.

After the utility model has been in operation for a period of time, the deposits at the bottom of the sedimentation tank, the inner tank, the water receiving tray and the water guide tank are removed, and the filter layer in the outer tank is cleaned and replaced to ensure the stable and efficient operation of the system.

The utility model has the advantages of simple structure, convenient operation, small occupied area, long service life, low energy consumption and high processing efficiency.
