Description
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 Aerobic Pond 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.
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 the processing of micro-polluted water more.
For aerobic biological process for treating, important factor is the oxygen level in the sewage, and the usefulness that therefore improves aerator is one of key that relates to purification efficiency and degree of purification.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of high-efficiency aerobic biochemical and artificial marsh sewage treatment system, this system can increase substantially the oxygen level in the sewage, effectively improves aerobic purification efficiency and degree of purification.
Technical scheme of the present invention is: a kind of high-efficiency aerobic biochemical and artificial marsh sewage treatment system, comprise and connect a heavy pond successively, Venturi meter, splash board, Aerobic Pond, second pond and artificial swamp, the convergent portion import of described Venturi meter connects the top in described one heavy pond by high-pressure pump, throat connects atmosphere by inlet pipe, the outlet of flaring portion is provided with the jet pipeline that extends forward, described splash board is positioned at described jet pipe front and Aerobic Pond top, be provided with the fixed bed of packings in the described Aerobic Pond, described second pond is positioned at the back of described Aerobic Pond, the water outlet that connects described Aerobic Pond, the water outlet of described second pond inserts described artificial swamp.
The present invention is by carrying out aeration efficiently in the Aerobic Pond front by modes such as Venturi meter and splash boards, increase substantially the oxygen level in the sewage, for the not too high general organic sewage of most concentration such as sanitary sewage, can effectively improve follow-up Aerobic Pond treatment condition, improve the aerobic biochemical processing power, improve the degree of purification of the water outlet of Aerobic Pond; Owing to be provided with artificial swamp, residual contamination thing in the sewage is carried out the processing of number of different types, even also can obtain satisfied degree of purification for the higher sewage of Pollutant levels thus in the aerobic treatment back.In addition, because a heavy pond is established in the Aerobic Pond front, the foreign material and the settleable matter of bulk in the sewage are precipitated out, alleviated the pollutant load of subsequent technique, and reluctant bulk of biochemical reaction and large particulate matter have been eliminated, avoid these materials to stop up bed of packings in Aerobic Pond, the setting of second pond then is used for precipitating mud and other settleable matters of sewage, avoids these mud to enter artificial swamp.In addition, this system architecture is simple, and is easy to operate, and adaptability is good, allows sewage quantity that bigger rangeability is arranged.
