Description

algae filter

technical field

The utility model belongs to the technical field of water treatment, in particular to a water treatment device used for algae removal and filtration of water bodies in river basins, lakes, reservoirs or reservoirs.

Background technique

In the water treatment process of domestic water and industrial water, it is usually necessary to carry out algae removal treatment on water bodies taken from river basins, lakes, reservoirs or cisterns. The existing algae removal technology mainly contains the following categories: one is the method of solid-liquid separation using mechanical screening, such as using a microfilter, the aperture of the filter screen of the microfilter is 10-45 μm (mostly 35 μm), The algae removal rate can reach 50% to 70%. The algae removal rate of the microfilter varies with the type of algae. The finer the algae is, the harder it is to remove. There is a long-term use of the filter to filter, and the filter needs to be removed and washed frequently. The lack of frequent disassembly and assembly of the machine not only consumes manpower, but also easily damages the machine and reduces the service life of the machine; the other is the filter algae removal device using membrane technology, which uses ion exchange membrane or organic polymer synthesis The mechanism of membrane composition can be divided into microfiltration, ultrafiltration, nanofiltration and reverse osmosis according to the different membrane pore sizes. Although this technology is the only technology that can achieve 100% algae removal, the membrane technology requires high Infrastructure investment and operating costs are rarely used in large-scale production practice at present; there is also a type of air flotation tank type algae removal device, which adopts the method of harvesting algae mechanically in a container, and the air flotation tank is suitable for turbidity less than 100NTU. Algae water, but the solid-liquid separation speed of this device is small, so it occupies a large area, and if the sludge is not properly treated, it will cause secondary pollution.

CN2490153 discloses a "dual-field type algae removal and sterilizer" water treatment device, which mainly sets two water treatment electric fields in the casing, and the positive and negative electrodes of the electric energy generator are connected to the anode tube and the cathode tube. After the water to be treated flows in through the inlet, it is treated successively by two water treatment electric fields to achieve the purpose of algae sterilization and disinfection. However, the use of electric energy generators has the problem of large energy consumption. Therefore, there is an urgent need for an algae-removing type filter with convenient cleaning, less investment and good algae-removing effect on the market to solve the problems in the prior art.

(2) After the water to be treated is pressurized by the water pump, it enters from bottom to top. After most of the water flows through the microfiltration tube, the clear liquid enters the water collection chamber and flows out from the outlet pipe. A small part of the water flow (carrying some retained impurities) passes through the waste water. pipe, and finally discharged from the waste water main. This filtration method can reduce the retention of retained impurities in the microfiltration tube and greatly improve the filtration efficiency; four microfiltration tubes are used in parallel to increase the filtration area; the pore size of the microfiltration tube is 30-50 μm, and the filtration effect is excellent. High; the microfiltration tube is made of stainless steel, which increases its strength and can withstand high pressure and should not be damaged;

(3) The backwashing of the microfiltration tube is to use the water pressure difference inside and outside the microfiltration tube to complete automatic flushing, which can overcome the shortcomings of other mechanical filtration devices that require an additional backwashing system, greatly reduce power consumption, and thereby reduce the operating cost of the device; When one microfiltration tube is used, the other three microfiltration tubes can work as usual through valve control, without affecting the normal filtration in water treatment;

(4) A settling bucket with an inclination angle of 45° is arranged under the device body, which is beneficial to remove deposited mud and sand; compared with the existing algae removal filter device, it also has the advantages of small footprint and good algae removal effect.
