Description

High-concentration sewage treatment system 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.
Enter the pollution load of artificial swamp for minimizing, improve the subject range of artificial wet land treating system,, can also utilize the natural wetland condition that wetland is transformed for place with good conditionsi, be adapted to the processing of higher concentration sewage, and do not need land occupation resource separately.Reducing concentration of wastewater can realize by pre-treating technology, for example aerobic biochemical, anaerobic biological, mechanical separation, flocculation sediment or the like, for these modes, need to consider the suitable condition of different places, stability of cost, place, maintenance, quantity of wastewater effluent or the like for example, under passable situation, sorting charge is with minimum pre-treatment mode.
The aerobe method is rapider, thorough than anaerobic treatment method to the removal of organic pollution materials, though need to consume more energy, but still be the most frequently used method of sewage disposal.The aerobe method is divided into two kinds of activated sludge process and biomembrance process substantially, and both differences are that the aerobic microbiological form with mud in sewage in the activated sludge process is the suspended state growth, and the embrane method microorganism then anchors on the filler of setting and grows.These two kinds of aerobic processes respectively have relative merits, and long developing history is arranged all, totally it seems, the former is better to the removal effect of organic pollutant, need lower initial cost, but operation is complicated, is used for the occasion than big yield more: and the latter more adapts to the impact load that the variation of water quality, the water yield brings, operate also simpler, thereby be used for the less water yield or micro-polluted water more. processing.Be very rough, in actual engineering, the aerobic process quality relatively be many-sided, comprise technology, economical and factor society etc.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of high-concentration sewage treatment system based on artificial swamp, the required floor space of this system is little, can concentration of treatment than higher sewage, and processing costs is relatively low.
Technical scheme of the present invention is: a kind of high-concentration sewage treatment system based on artificial swamp, comprise anaerobic hydrolysis pond, activated sludge tank, second pond and artificial swamp, the water outlet in described anaerobic hydrolysis pond inserts described activated sludge tank, the water outlet of described activated sludge tank inserts described second pond, and the water outlet of described second pond inserts described artificial swamp.
The present invention has adopted the combination of kinds of processes, earlier larger molecular organics is decomposed into the small organic molecule that is easy to aerobic biochemical by the anaerobic hydrolysis pond, because sewage is in the oxygen consumption of the process of catchmenting, this anaerobic hydrolysis is easy to realize and the regulation and control operating parameter, and can not produce peculiar smell overflows, then by described activated sludge tank aerobic biochemical, micromolecular organism further is decomposed into inorganics and water, warp is at the second pond post precipitation, water enters artificial swamp and carries out the various ways biological treatment, owing to before artificial swamp, carried out hydrolysis and aerobic treatment, greatly reduced pollutants in sewage concentration, help improving the hydraulic load of artificial swamp, improve the degree of purification of water outlet.In addition, this system architecture is simple, and is easy to operate, is adapted to the processing of the sewage of higher concentration.
Description of drawings
Fig. 1 is a system architecture synoptic diagram of the present invention.
