Description

Interim integral type sewage precipitation treatment equipment in building site

Technical Field

The utility model belongs to the technical field of sewage treatment equipment, and particularly relates to temporary integrated sewage precipitation treatment equipment for a construction site.

Background

The sewage contains a large amount of organic matters, such as cellulose, starch, grains, fat and protein. There are also pathogenic bacteria, viruses and parasite eggs; without chloride, sulfate, phosphate, bicarbonate, sodium, potassium, calcium, magnesium, and the like. The total characteristics are that the total nitrogen and the total phosphorus are high, and malodorous substances are easy to generate under the action of anaerobic bacteria. With the steady promotion of national economy, the infrastructure construction of real estate, transportation, airports, ports, bridge communication, water conservancy and the like is developed all over the country. The construction site with large attached scale is a functional carrier for catering, washing, lodging and the like, which must generate a large amount of sewage, the main sources are concentrated in the food and wash places and toilets, and aerobic microorganisms and digestive bacteria oxygen microorganisms exist in septic tanks or other treatment facilities to decompose organic matters into CO2 and H2O; under the condition of sufficient oxygen supply, the nitrification of nitrifying bacteria oxidizes the nitrifying bacteria into O3-, and through sample control and anaerobic conversion, the denitrification of heterotrophic bacteria under the anoxic condition makes NO 3-minute oxygen automatically flow into the sedimentation tank for sedimentation, the effluent of the sedimentation tank enters the disinfection tank for chlorine dioxide disinfection, and the disinfected effluent is discharged after reaching the standard.

The sedimentation tank is a common sewage treatment device, the sedimentation tank is mostly in a advection type structure, wastewater enters the sedimentation tank with a rectangular plane through a water distribution tank and slowly flows along the horizontal direction, oil products float on the water surface in the flow, and the oil products are pushed into an oil collecting pipe by an oil collecting pipe or an oil scraper arranged on the surface of the tank to flow into a dewatering tank.

The sewage treatment process is an integral project designed according to the characteristics of sewage quality, and common domestic sewage, industrial sewage and the like can be treated by adopting different treatment processes. The sewage of the construction site has different characteristics, and because the workers in the construction site are dense and the amount of the wastewater generated in the construction process is large, a matched sewage treatment facility needs to be independently constructed, and the sewage treatment system has important significance for protecting the health and safety of the surrounding environment and the living environment of the camp.

The construction site sewage has the characteristics of dispersion, large amount, and the like. The places where part of the construction sites are built do not have urban sewage pipeline collecting systems, so that the urban sewage pipelines are difficult to be concentrated to urban sewage treatment plants for uniform treatment, and a treatment facility mode suitable for the characteristics of the construction sites is developed. However, construction sites can be distinguished according to the matching conditions of the sites, for example, the sites are located in mature city groups, a sewer pipeline system for receiving domestic sewage is arranged, and the domestic sewage in the construction sites does not need to be mixed and is directly discharged into sewer pipelines for centralized treatment. However, other sewage except domestic sewage needs to be treated separately, and the sewage with the characteristics of oil stain and a large amount of phosphoric acid, nitric acid and sulfate cannot be treated quickly and effectively in a biological treatment mode, so that a large-scale sewage treatment facility is established, the cost is higher, and a construction site does not have the condition for arranging a large-scale fixed sewage treatment facility.

Further, have a plurality of heavy grooves in the settling zone, heavy groove bottom central point puts and all has a mud discharging port, outwards transmits mud through being equipped with the sludge pipe 3 that communicates every mud discharging port in support 4. Simultaneously, in order to realize better sediment control, still be equipped with in this application and add the medicine pipeline, mix the back with the medicament through the pipeline input deposit the district by the medicine mixing pump that the outside set up. Since this embodiment has two settling zones, the drug filling is typically performed by two separate dosing and mixing pumps. The added agents can be adjusted according to requirements and generally comprise flocculating settling agents, demulsifiers, coagulant aids, pH regulators, disinfectants and the like.

A dosing port is arranged for each sinking groove, the water quality monitoring system is used for monitoring water quality, a management program and a control system can be preset according to the actual water quality condition, and parameters such as medicament delivery quantity, delivery time, hydraulic retention time, sludge discharge period and the like of the whole equipment are managed through the control system.

A connecting pipe 8 is provided between the two settling zones, and a three-way valve (not shown) is provided on the connecting pipe 8. The three-way valve is not only connected with the settling zone at the other side, but also connected with the water storage barrel 2 arranged outside through a pipeline, and the water outlet pipe mouth of the other settling zone is also connected with the water storage barrel 2 through a pipeline. Still be provided with quality of water sampling pipe mouth alone in retaining bucket 2, go out water quality of water in case change, the accessible changes and corresponds the processing parameter and realize better process control.

For example, when the amount of the entered sewage is large, the medicine filling amount can be properly increased in a step mode, the water levels of the settling areas on the two sides are enabled to be at a high position, the quality of the discharged water is monitored, and once the situation that the discharged water does not reach the standard occurs, the return pipe is opened for retreatment.

Meanwhile, if the water amount is reduced or the sludge amount in the later settling zone is obviously reduced through detection, the medicament amount can be reduced or one settling zone can be directly closed, so that the operation cost can be reduced, and the closed settling zone can be cleaned.

It should be noted that the structure of the tank body 1 shown in the attached drawings is only schematic, and the scale and the pipeline design of the tank body are not the same as those of the equipment actually constructed.

The present invention is not limited to the above-described alternative embodiments, and various other forms of products can be obtained by anyone in light of the present invention.
