Description

A kind of novel hydraulic type enhanced biological septic tank
Technical field
The utility model relates to the domestic sewage in rural areas by using biological treatment and sewage recycling utilizes technical field, is meant a kind of novel hydraulic type enhanced biological septic tank especially.
Background technology
In recent years, wastewater treatment in China factory constantly builds, but mainly concentrates on the city, and the sewage in national most of rural area can not get handling.The processing approach of domestic sewage in rural areas by using mainly contains two kinds at present: the one, include sewage in city planting ductwork; The 2nd, set up sewage on-the-spot disposal facility.The densely populated zone in the urban district; Improve pipe network and collect fraction of coverage, the lifting sewage ability of focusing on is undoubtedly correct choice, and in the exurb; Concentrated pipe network can't be led to; Even can extend with main roads, adapter expense and long-distance sewage pumping station are carried, working cost is all very high, and the unit cost of sewage disposal also improves greatly.Therefore, rural decentralized wastewater should be taked the mode of on-the-spot disposal.Septic tank is used as a kind of sewage on-the-spot disposal facility easy, that need not to consume energy widely, and is wherein, extensive with the use of three format manure pits.
Because the blow-by of the septic tank of a design part can't be collected biogas at present; Though another part is with the septic tank sealing, the biogas air pressure that produces is unstable, is prone to cause explosive incident.In addition, when fecal sewage and sewage interflow entered septic tank, short easily on the one hand stream made C/N than reducing on the other hand, influences the generation of biogas.The septic tank effluent concentration of suspension is high, and it also is a problem demanding prompt solution that a large amount of mikrobes are run off.
Summary of the invention
The purpose of the utility model is the above-mentioned shortcoming and defect that exists to prior art, and a kind of novel hydraulic type enhanced biological septic tank is provided.
The utility model is the technical scheme that its purpose of solution is taked:
A kind of novel hydraulic type enhanced biological septic tank is made up of spherical tank body and two opening for feeds thereof and a wet well.It in the spherical tank body one three format manure pit; On its vault, do well head, double-deck movable well lid is installed on well head, guarantee resistance to air loss, can conveniently pass in and out during maintenance in any lattice in three lattice; Its head space is an air storage chamber, and gas pipe line is set, and makes methane recovery, turns waste into wealth.Opening for feed has 2, is respectively solid manure opening for feed and liquid manure opening for feed.The solid manure opening for feed connects first grid septic tank, and the liquid manure opening for feed connects second septic tank.Solid-liquid is shunted, and increases the C/N ratio of first grid septic tank, improves biogas output.Hang with the soft-filler that fixes in the three-grid septic tank; Microorganism concn and area that contacts with pollutent and time in the pond have been increased greatly; Played simultaneously the effect of water distribution uniformity again, avoided taking place short flow phenomenon, and suspended substance has been had good crown_interception; Reduce the loss of mikrobe, improved effluent quality.Wet well connects three-grid septic tank, and wet well is provided with the bend pipe water outlet, guarantees that whole system is in the water seal state, guarantees that the biogas that is produced can only upwards get into air storage chamber, and water outlet also is a riser simultaneously.When internal system biogas increased gradually, air storage chamber pressure was pressed onto opening for feed and wet well respectively with three format manure pit liquid, to reach internal and external pressure balance along with increasing.When the user used biogas, the pond internal pressure reduced, and the liquid level of opening for feed and wet well reduces, and liquid returns in the pond, to keep new balance.In general, when aerogenesis, when using gas, the fermented liquid hand-deliver in ager and the pond just produces certain pressure for rising, descending, and can guarantee that biogas is carried, the requirement of incendiary pressure.But when biogas produces when excessive, huge pressure is a very big potential safety hazard, also can liquid flooding be gone out opening for feed simultaneously, has a strong impact on environmental health, and therefore riser is set in the utility model.
The advantage of the utility model mainly comprises:
1, the utility model adopts the mode charging of solid-liquid ight soil shunting, increases the C/N ratio of first grid septic tank, has improved the productive rate of biogas; Reduce the C/N ratio of second grid septic tank simultaneously, helped the enrichment anaerobic ammonia oxidizing bacteria, can play certain denitrification effect.
2, the utility model adopts the design of hydraulic type septic tank, can not only a good water seal effect be arranged to septic tank, and can discharge air pressure by balance biogas, and SF is high.
3, in the utility model three-grid septic tank hanging filler is housed, specific surface area is big, and microbial biomass is high in the unit volume; But the effect of water distribution uniformity avoids taking place short flow phenomenon, and suspended substance is had good crown_interception; Reduce the loss of mikrobe, improved effluent quality.
4, the utility model has strengthened decontamination effect improving, and the effective rate of utilization of pool volume is high.
5, the utility model is imbedded undergroundly, does not influence any facility in ground, and good heat preservation performance does not receive seasonal effect, and microbial metabolism is stable.
6, the utility model good airproof performance, no stink is not multiplied mosquitos and flies, noiseless.
7, the utility model is no energy consumption equipment, investment, economic operating cost.
In a word, the utility model be a kind of rational in infrastructure, aerogenesis is effective, do not have gas leakage, SF is high, the water outlet concentration of suspension is low, evolution usefulness is high, cost of investment is low a kind of novel hydraulic type enhanced biological septic tank.
