Description

Sewage interception filtration equipment

Technical Field

The utility model relates to an environment improvement technique.

Background

The municipal sewage treatment process generally determines the treatment degree of sewage and a corresponding treatment process according to the utilization or discharge direction of the municipal sewage and considering the natural purification capacity of a water body.

The sewage treatment technology is divided into a first-stage treatment process, a second-stage treatment process and a third-stage treatment process according to the treatment degree. The first stage treatment of sewage is carried out by removing insoluble suspended solids and floating substances from sewage by physical methods such as screening, sedimentation, etc. The secondary treatment of sewage is mainly a biological treatment method, namely a process of substance conversion through the metabolism of microorganisms, and various complex organic substances in the sewage are oxidized and degraded into simple substances. The third-stage sewage treatment is to remove insoluble organic matters, phosphorus, nitrogen and other nutritive substances in sewage by physical and chemical methods such as coagulation, filtration, ion exchange, reverse osmosis and the like on the basis of the first-stage treatment and the second-stage treatment.

The primary treatment of the sewage is pretreatment, the secondary treatment is main body, and the treated sewage can generally reach the discharge standard. The third-stage treatment is advanced treatment, the effluent quality is better and even can reach the drinking water quality standard, but the treatment cost is high, and the application is less except in some countries and regions with extreme water shortage

The biological treatment method can specifically adopt a biological contact oxidation method to treat wastewater, a biological film is fully distributed on the filler, the wastewater is in wide contact with the biological film, organic pollutants in the wastewater are removed under the action of metabolism of microorganisms on the biological film, and the wastewater is purified.

SUMMERY OF THE UTILITY MODEL

Detailed Description

Referring to fig. 1, the sewage intercepting and filtering device is arranged in front of a sewage draining exit 10 and comprises an intercepting cloth 20 which is vertically arranged and a biological membrane carrier 30 which is matched with the intercepting cloth, wherein the biological membrane carrier is vertically arranged, and at least one layer of the intercepting cloth is positioned in front of the biological membrane carrier.

Drain 10 can be located the top or the below of water level line, however, must fall from drain exhaust sewage the rear of sewage interception filtration equipment, sewage flows forward, filtration equipment just can purify sewage.

The intercepting cloth 20 does not completely prevent the sewage from passing through, but decelerates the sewage to slowly pass through the intercepting cloth and the biofilm carriers 30. Under the blocking of the intercepting cloth, the sewage staying near the intercepting cloth can be purified as sufficiently as possible by the microorganisms on the biofilm carrier, so that the purifying effect is improved.

The intercepting cloth 20 is vertically arranged, the biological membrane carrier 30 is vertically arranged, and the intercepting cloth and the biological membrane carrier are both vertical to the water surface and in a vertical state.

The number of the intercepting cloths 20 is not limited to one layer, and may be a plurality of layers arranged in front of and behind each other with a certain distance therebetween, which can accommodate one layer of the biofilm carriers 30, and which can also serve only as a water flow decelerating function. In this way, when the intercepting cloth 20 has a plurality of layers, the biofilm carriers 30 may have a plurality of layers and be distributed in the gap between the intercepting cloth and the intercepting cloth.

In the whole structure of the intercepting cloth 20 and the biofilm carrier 30, the intercepting cloth should be a layer of the intercepting cloth at the forefront rather than the biofilm carrier, because the intercepting cloth can block the sewage and the sewage is decelerated and reflows, and the biofilm carrier behind the intercepting cloth can purify the sewage as fully as possible by using the condition. If the layer of intercepting cloth and the layer of biological membrane carrier behind the layer of intercepting cloth form a purification unit, a plurality of intercepting cloths and biological membrane carriers which are arranged alternately form a plurality of purification units which are arranged in front of and behind the purification units. As shown in fig. 1, the sewage intercepting and filtering device is provided with two layers of intercepting cloth 20 and two layers of biofilm carriers, totaling two purification units.

As shown in fig. 2, the floating objects 40 are connected to the top of the intercepting cloth 20, and the weights 50 are connected to the bottom of the intercepting cloth, so that the intercepting cloth is erected. The biofilm carrier 30 is connected with the floats and is next to the intercepting cloth, the biofilm carrier 30 is in a vertical state under the action of the gravity of the biofilm carrier, and if necessary, a heavy object can be connected to the bottom of the biofilm carrier to enable the biofilm carrier to be in a vertical state, namely in a vertical state. Alternatively, the float 40 may be a floating ball, and the weight 50 may be an annular metal ring.

In practice, the floats 40 above the intercepting cloth 20 are strung using first connecting ropes 41 connected to stakes fixed in the river or the pond to position the floats. The intercepting cloth 20 positioned under the string of floats is connected to the first connecting string 41 by the second connecting string 21. The biofilm carrier 30 is connected to a first connection string 41.

Alternatively, the biofilm carrier 30 is composed of a plurality of carbon fiber grasses. The purification unit is explained by one, and comprises a layer of intercepting cloth and a layer of biological membrane carrier, wherein the layer of biological membrane carrier is adjacent to the intercepting cloth and positioned behind the intercepting cloth; the layer of biofilm carrier is composed of a plurality of carbon fiber grasses which are all connected with a third connecting rope 31, and the third connecting rope is connected with a first connecting rope 41, so that the connection of the layer of biofilm carrier and a string of floats 40 on the layer of biofilm carrier is realized.

Alternatively, the intercepting cloth 20 is made of polyethylene.

As an improvement, like fig. 1, sewage interception filtration equipment partly surrounds drain 10, and the drain setting is on sewage pool wall or sewage revetment, sewage interception filtration equipment and sewage pool wall or sewage revetment soil, form the enclosure to the drain, can purify the sewage that comes from the drain not leaving over. Alternatively, the sewage intercepting and filtering device is in the shape of a circular arc, and both ends of the sewage intercepting and filtering device are respectively bordered with the wall of the sewage pool or the sewage revetment.

In order to purify the sewage from the sewage drain 10 more without leaving behind, the bottoms of the intercepting cloths 20 and the biofilm carriers 30 are sunk to the bottom of the sewage tank or the bottom of the river.

In actual operation, about five days later, a mucous biofilm appears on the part of the biofilm carrier 30, and microorganisms begin to adhere and grow; after about ten days, a large number and a large variety of attached growth microorganisms appear on the surface of the biofilm carrier. Various algae and zooplankton such as diatom, mythimna separata, coccoid, rotifer and nematode can be detected from the biomembrane formed on the surface of the biomembrane carrier. The appearance of rotifers at the later stage is a sign that the water body is in a low-pollution zone, which indicates that the water quality is gradually good.

Sewage interception filtration equipment can regard as the secondary treatment technology's of municipal sewage treatment equipment to use, also can directly handle the domestic sewage that discharges in the river course.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
