Abstract

The present invention relates to a kind of Sewage treatment systems based on artificial swamp, it comprises grid, water collecting basin, flocculation drug mixing pool, settling tank, aeration tank and the artificial swamp that connects successively, the matrix of described artificial swamp be in sand compound, rubble, zeolite, Wingdale, cinder, slag, blast furnace slag, rubble, haydite, melon seeds sheet and the cobble any one or several arbitrarily, the water outlet of described settling tank is provided with overflow weir, by the overflow weir water outlet, in the described flocculation drug mixing pool stirring rake is set.The present invention enters Pollutant levels in the sewage of artificial swamp significantly, some pollutents that are difficult for carrying out biochemical treatment also can take out through the mode of flocculation sediment, reduced to enter pollutant load in the sewage of artificial swamp thus, therefore also just can reduce the area of artificial swamp, reduce pollutent and in artificial swamp, deposit, avoided the generation of problems such as obstruction.Mainly be adapted to sanitary sewage and other similar organic sewages.

Description

Sewage treatment systems based on artificial swamp
Technical field
The present invention relates to a kind of Sewage treatment systems, particularly a kind of comprehensive sewage treatment system in conjunction with various processing modes based on artificial swamp belongs to field of environment protection.
Background technology
The mankind use precipitation, filtration process as centralized water treatment plant the earliest from Englishman in 1804, the American had invented coagulation, precipitation, filtration, chlorine disinfectant technology in 1884, use the history in existing 120 years till today, though the mankind constantly have new discovery and raising aspect clean water treatment, but the treatment process of domestic water but remains unchanged basically, does not upgrade in essence and breaks through.Yet very big variation has but taken place at the water source of process object: the water source before century-old is because industrial, agriculture undeveloped, and water body is not contaminated.And in decades, development of modern industry, especially chemical engineering industry happen suddenly, industrial wastewater discharge, the loss of agrochemical, agricultural chemicals, the pollution of sanitary sewage etc., serious day by day to the contaminated degree of source water, make the traditional water treatment process be difficult to guarantee fine water.
Artificial marsh sewage treatment system is a kind of sewage disposal technology that grows up the seventies in 20th century, compare with traditional sewage second-level biochemical processing process, have that good purification, processing unit are simple, the during-operation service convenient management, energy consumption is low, system configuration plasticity-strong,, engineering capital construction strong to load variations adaptability and working cost is low, water outlet has certain biological safety, ecological environment benefit significantly, can realize characteristics such as sewage recycling, obtain people's attention just more and more.Its defective is that floor space is big, and is easy to occur problem such as obstruction, is not suitable for the higher sewage disposal of pollution concentration.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of Sewage treatment systems based on artificial swamp, the required floor space of this system is little, is not prone to problems such as obstruction, can concentration of treatment than higher sewage.
Technical scheme of the present invention is: a kind of Sewage treatment systems based on artificial swamp comprises the grid, water collecting basin, flocculation drug mixing pool, settling tank, aeration tank and the artificial swamp that connect successively.
Owing to before sewage enters artificial swamp, carried out technologies such as grid, flocculation sediment, oversize material and the organism that can remove through flocculating and the particulate matter etc. in the sewage have been eliminated significantly, make the Pollutant levels of sewage significantly less, some pollutents that are difficult for carrying out biochemical treatment also can take out through the mode of flocculation sediment, reduced to enter pollutant load in the sewage of artificial swamp thus, therefore also just can reduce the area of artificial swamp, reduce pollutent and in artificial swamp, deposit, avoided the generation of problems such as obstruction.
Description of drawings
Fig. 1 is a system architecture synoptic diagram of the present invention.
Embodiment
Referring to Fig. 1, the present invention is to the processing elder generation process grid of sewage and the pre-treatment of flocculation sediment, and through aeration, enter the oxygen level of artificial swamp sewage with raising, avoid the peculiar smell that causes because of hypoxgia in the artificial swamp and to the negative impact of purification of water quality, improve the biodegradability of sewage, the mechanical grille under the preferred prior art of grid wherein, remove big solid sundries through mechanical grille, enter water collecting basin, when in water collecting basin, catchmenting, stirring rake or submersible pump are set in water collecting basin sewage is carried out homogenizing, then in the flocculation drug mixing pool, by on the flocculation drug mixing pool, administration device being set, in sewage, add flocculation medicament (flocculation agent and coagulating agent etc.), for common sewage, the concentration range of flocculation medicament is between 50-100mg/L, in the flocculation drug mixing pool stirring rake is set, stir, to improve flocculating effect, sending into settling tank then precipitates, after the mud of settling tank is squeezed into sludge thickener and is concentrated by the sludge pump that is provided with in settling tank bottom, row processing again, the water outlet of settling tank is provided with overflow weir, by the overflow weir water outlet, flow into the aeration tank, carry out sending into artificial swamp behind the aeration in the aeration tank, these pollutants in sewage content reduce significantly, and by modes such as aerations the oxygen level in the water is increased considerably, avoid the peculiar smell of artificial swamp to worsen environment on every side.
Described flocculation medicament can adopt iron trichloride, ferrous sulfate, ferric sulfate, the combination of one or more in Tai-Ace S 150, alum, aluminium chlorohydroxide, polymerize aluminum chloride, bodied ferric sulfate, aluminium iron polychloride, polymeric aluminium-silica, polymerization iron silicon and the polypropylene phthalein amine.
The matrix of described artificial swamp can adopt one or more the mixture in sand compound, rubble, zeolite, Wingdale, cinder, slag, blast furnace slag, rubble, haydite, melon seeds sheet and the cobble.The plant of artificial swamp can be adopted the suitable plant that is suitable for local environment conditions and sewage disposal needs, for example reed, Canna generalis Bailey, cattail, Rush, giantreed, Caulis Miscanthis floriduli etc.
By this processing mode, can significantly improve the hydraulic surface loading that artificial swamp is disposed of sewage, reduce the floor space of artificial swamp, reduce the sewage treatment project investment cost, for sanitary sewage and other similar combined sewages, through reaching emission standard after the native system processing.
