Abstract
The combined process of reinforced biochemical flocculation and artificial wet land treatment of sewage includes the following steps: A. pre-treatment through eliminating large solid foreign mater in lattice, collecting to well and pumping to the regulating pond for homogenizing; B. reinforced biochemical flocculation inside reaction pond with flocculant and coagulant in concentration 0-100 mg/L and sludge-water separation in settling pond; and C. artificial wet land treatment with exhaust reaching the discharge or reuse standard. The present invention has the advantages of no jamming of artificial wet land, greatly raised surface treating load, reduced covered area of artificial wet land, and low sewage treating cost, etc.
Description
Technical field
The invention belongs to environmental protection science and engineering field, the novel process that relates to a kind of sewage disposal specifically is the combined sewage treatment process of reinforced biochemical flocculation and artificial swamp.
Background technology
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.
But present artificial swamp ubiquity: floor space is big and easily stop up two significant deficiency, thereby has limited the popularization of constructed wetland waste water treatment technology.
Summary of the invention
Deficiency at prior art exists the object of the present invention is to provide a kind of " reinforced biochemical flocculation+artificial swamp " combined sewage treating process.
It is the sewage treatment process that utilizes biofloculation and the symphyogenetic reinforced deposition of chemical flocculation that biofloculation is strengthened.In such system, the sunk solid in the water inlet can obtain activation, has good flocculation adsorption and settling property, except that dissolved matter and fine can not sink suspended solids of absorption in the sewage, also can make dissolved organic matter obtain the part degraded.
Constructed wetland waste water treatment technology is by going up the specific wetland plant of plantation in certain matrix (sandstone, soil etc.), thereby set up artificial Wetlands ecosystems, when sewage passes through system, pollution substance wherein and nutritive substance are purified water quality by absorption or decomposition such as the microorganisms that is produced in the system.
Goal of the invention of the present invention is achieved by the following technical solution:
A kind of reinforced biochemical flocculation, artificial swamp combined sewage treating process, its step is as follows:
A, pre-treatment: sewage is removed big solid sundries through mechanical grille, enters pump well, and the pump well sump pump is delivered to equalizing tank homogenizing water quality and quantity;
B, reinforced biochemical flocculation are handled: add flocculation agent and coagulating agent in reaction tank, the concentration range of flocculation agent and coagulating agent enters settling tank through the reacted sewage of reinforced biochemical flocculation between 0～100mg/L, carry out mud-water separation;
C, artificial swamp are handled: the water outlet of settling tank enters artificial swamp and handles, artificial wetland effluent qualified discharge or reuse.
Described flocculation agent and coagulating agent are 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 polyacrylamide.
Described artificial swamp matrix is 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 present invention adopts biofloculation to strengthen pretreatment technology before sewage enters artificial swamp can significantly reduce water inlet Pollutant levels, the especially concentration of suspension that enters the Wetland ecological processing.This combination process can effectively solve dispose of sewage latch up phenomenon in the operational process of artificial swamp, can significantly improve the hydraulic surface loading that artificial swamp is disposed of sewage, and reduces the floor space of artificial swamp, reduces the sewage treatment project investment cost.Case history proves, the sanitary sewage after " reinforced biochemical flocculation+artificial swamp " combined sewage treating process is handled, and its water outlet can reach " town sewage plant pollutant emission standard " (GB18918-2002) middle one-level B standard.
