The technical problems solved by the invention are as follows: provides a simple and cheap sewage purification facility.

In order to solve the technical problems, the invention provides the following technical scheme: a preliminary sewage purification facility of drain comprises bags and solid microorganisms, wherein the solid microorganisms are contained in the bags, and a plurality of bags are stacked in front of the drain.

Microorganisms are a generic term for organisms that are invisible or obscured to the naked eye. Including prokaryotes (bacteria, actinomycetes and cyanobacteria), eukaryotes (fungi and microalgae), and acellular organisms (viruses). The microorganism has the characteristics of small volume, large surface area, remarkable fertility and the like, and can continuously and rapidly exchange substances with the surrounding environment. The sewage has the condition of microorganism growth and reproduction, so the microorganism can obtain nutrients from the sewage and degrade and utilize harmful substances, thereby purifying the sewage.

According to the invention, the bags filled with the solid microorganisms are stacked in front of the sewage discharge outlet, namely the outlet of sewage discharged from the sewage discharge outlet, sewage flow is blocked by the stacked bags, the speed is slowed, and at the moment, the solid microorganisms in the bags purify the sewage, so that the sewage purification is facilitated, and the sewage purification effect is improved.

The sewage purification facility has a simple structure, is a common material, has low cost, can be used for the inconvenient arrangement of a sewage discharge outlet of the purification equipment in the prior art, or the arrangement of an uneconomical sewage discharge outlet of the purification equipment, or the arrangement of a sewage discharge outlet of the purification equipment with high cost in the prior art is not needed, can preliminarily purify sewage, has positive technical effect, and can be matched with other purification equipment with low cost and small occupied space for use.

Detailed Description

Referring to fig. 1 and 2, a preliminary sewage purification facility for a sewage draining exit comprises a bag 10 and solid microorganisms 20, wherein the solid microorganisms are contained in the bag, and a plurality of bags are stacked in front of the sewage draining exit 30.

In practical operation, the sewage flow flowing out of the sewage draining outlet 30 is blocked by the stacked bags 10, the sewage flow can pass through the bags 10 and the solid microorganisms 20 therein only at a slow speed, at the moment, the solid microorganisms in the bags purify the sewage, so that organic matters in the sewage can be treated as much as possible, and meanwhile, the bags and the solid microorganisms therein can also filter the dirt in the sewage.

Alternatively, the bag 10 is an ecological bag. The ecological bag is an ecological synthetic material with high strength, ultraviolet resistance, freeze-thaw resistance and acid and alkali resistance, is a novel special material in high and new technology, has the advantages of high strength, UV resistance, acid and alkali resistance, corrosion resistance, freeze-thaw resistance and no degradation for more than 70 years.

The solid microorganisms of the present invention are microorganisms attached to solid materials. Alternatively, the solid substance is steel slag, which has a greater mass and has a positive effect on the stability of the bag 10 in river water. In actual operation, the steel slag can be soaked in a microorganism pool, microorganisms are attached to the steel slag, and then the steel slag is filled into the bag 10; alternatively, the steel slag is first placed in the bag 10, and the bag is then soaked in a microbial pool, and the microbes permeate into the bag and adhere to the steel slag.

As an improvement, a limiting structure for limiting the bags is arranged in front of the stacked bags 10. The limit structure may be a pile fixed to the bottom of the river, and the bag 10 may be supported against the pile to prevent the water from the drain 30 from being impacted and not displaced. A limiting structure can be arranged behind the bag 10 to improve the impact resistance of the bag 10 in a river. The limiting structure can also be a net, the net is firstly laid on the river bottom, a plurality of bags 10 are stacked on the net, then the net is collected to wrap all the bags, so that all the bags are integrated, and the shock resistance is improved.

The height of the stacked bags 10 is higher than the waste outlet 30 so that the bags 10 and the solid microorganisms 20 therein can purify the waste water from the waste outlet as sufficiently as possible.

Several bags 10 are stacked in a semi-enclosed structure, as shown in fig. 1, with both ends bordering a revetment 40 where a drain 30 is located, within the semi-enclosed structure. Therefore, the sewage discharged from the sewage discharge outlet can completely pass through the stacked bags 10, and the effective degree of the purification facility for purifying the sewage is improved. Preferably, the semi-enclosed structure is curved, i.e., the plurality of bags 10 stacked together are curved as a whole.

As an improvement, with reference to fig. 1 and 2, the filler 50 is filled in the gaps between the upper and lower adjacent bags 10 and between the left and right adjacent bags, so that the full and thoroughness of the semi-enclosed structure for enclosing the sewage draining exit 30 is realized, and no waste sewage flow is missed. The filler can be attached with microorganisms, filter dirt and purify sewage. The filling material 50 may be laid on a layer of bags during the stacking of the bags 10, and then a layer of bags may be stacked thereon after the laying, so that the filling material can be pressed between the bags and is not easily dispersed by the flowing water. Alternatively, the filler 50 is a ceramic particle.

As shown in fig. 1 and 2, aquatic plants 60 are arranged above a plurality of stacked bags 10, and the upper half parts of the aquatic plants are positioned on the water surface. In actual operation, aquatic plants are planted in a plurality of basins, the basins are connected together through a rope to form a string of basins, and two ends of the string of basins are connected to a revetment 40 of a river channel through the rope. Or sludge is arranged above the stacked bags 10, aquatic plants are planted on the sludge, and root systems of the aquatic plants extend downwards into river water. The function of the aquatic plants: firstly, the river channel is provided with a sewage purification facility, so that the warning effect is achieved; secondly, absorb the ammonia nitrogen in the sewage, play the purification effect to the sewage.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description herein, since various changes and modifications can be made in the details of the embodiment and the application range according to the spirit of the present invention.
