Description
Technical Field
the invention belongs to the technical field of sewage treatment, and particularly relates to a garbage leachate treatment process.
Background
the urban garbage is a difficult problem for urban environment management, and the garbage leachate of a garbage transfer station, an incineration plant or a landfill is composed of various compounds and rotten substances which are vomited and contain BOD, COD, nitrogen-containing compounds, phosphorus-containing compounds, organic halides, sulfides, inorganic salts and the like with extremely high concentration, so that the garbage leachate not only has foul smell, but also is a few carcinogenic substances. If the water body is discharged, the environment is polluted, the water source is dissolved underground and polluted, the urban environment and the human health are great hazards, the toxicity is far greater than that of the conventional urban sewage, and therefore the landfill leachate is required to be treated to reach the standard and can be discharged.
The landfill leachate is high-concentration organic wastewater which has complex components and large water quality and water quantity change. The source of the garbage percolate is direct precipitation, surface runoff, surface irrigation, underground water, garbage moisture, moisture in a covering material, water generated by biochemical reaction of the garbage and the like; the factors influencing the landfill leachate mainly comprise: the garbage composition, the site climatic condition, the hydrological rainfall condition of the site, the landfill condition, the landfill time and the like determine that the water quality and the water quantity of the garbage leachate have large change, the change rule is complex, the ammonia nitrogen of the leachate is increased year by year along with the increase of the site age, and the biodegradability is poor. The physicochemical and biochemical characteristics and the activity modes of all parts of the landfill sites are different, the PH value of the percolate of a young landfill site (within five years) is lower, the COD, the BOD, the VFA, the metal ion concentration and the BOD5/CODcr are higher, the PH value of the percolate of an old landfill site (more than ten years) is more neutral, the COD, the BOD, the VFA and the BOD5/CODcr are lower, the metal ion concentration is reduced, but the ammonia nitrogen concentration is higher.
after 2000 years, due to rapid development of economy, newly-built percolate treatment plants are generally far away from urban areas, percolate is not discharged into urban sewage pipe networks without conditions, so the treatment requirement is correspondingly improved, the treatment is generally required to reach the second-level or even first-level discharge standard, most of the refuse is not fermented and aged at the initial operation stage of the refuse landfill, and meanwhile, the fresh refuse carries more water, so the COD (chemical oxygen demand) of the landfill percolate is higher, and the landfill leachate has better biodegradability, and can be treated by adopting a biological method, such as anaerobic-aerobic combined processes such as UASB (anaerobic sludge bed reactor) anaerobic process, ASBR (anaerobic process), SBR (sequencing batch reactor) aerobic process, A2O (anaerobic-aerobic combined process) and. Along with the operation of the refuse landfill, the landfill garbage is gradually fermented and aged, a large amount of biodegradable substances are consumed, the COD value of the landfill leachate is reduced, meanwhile, the biodegradability is also reduced, and the applicability of biochemical treatment is weakened or even infeasible. Therefore, the emission standard is difficult to reach by adopting a simple biochemical treatment process.

Thirdly, putting the landfill leachate after anaerobic treatment into an aerobic tank, and carrying out oxidative decomposition for metabolism under the action of high-activity aerobic microorganisms;
After aerobic treatment, pumping the landfill leachate into a microfiltration filter by using a microfiltration filter, and then, entering a microfiltration production water tank for filtering;
step five, after the filtration of the microfiltration water production tank is finished, putting the garbage leachate into a quartz sand filter, removing suspended matters, and then putting the garbage leachate into the quartz sand water production tank for storage;
step six, performing nanofiltration on the landfill leachate in the quartz sand production water tank to further separate refractory large molecular organic matters, and storing the organic matters in the nanofiltration production water tank;
Seventhly, performing reverse osmosis treatment on the landfill leachate in the nanofiltration water production tank by adopting a reverse osmosis membrane, wherein the reverse osmosis operating pressure is 1.5-10.5 MPa, and the interception component is (1-10) multiplied by 10-10m small molecular solute and finally discharging the treated water reaching the standard.
The working principle and the beneficial effects of the invention are as follows:
The garbage leachate treatment process in the scheme comprises the steps of firstly, performing primary sedimentation and separation on the garbage leachate through a regulating tank,The buffering capacity of the treatment load of the landfill leachate is provided, water quality homogenization and water quantity regulation are carried out simultaneously, high-concentration toxic substances are guaranteed not to enter a subsequent treatment system, fluctuation of sewage flow is reduced, after the landfill leachate enters an anaerobic tank, the garbage leachate is subjected to microorganism anaerobic metabolism, macromolecule difficultly-degradable organic matters are decomposed into micromolecule easily-degradable organic matters and are finally converted into methane, carbon dioxide and water, after the anaerobic treatment, wastewater automatically flows into an aerobic treatment unit, the organic matters in the water are ingested through life activities such as metabolism of microorganisms, and part of CODcr, BOD and water are removed5、NH3-N; in the aerobic pool, through the action of high-activity microorganisms, oxidative decomposition carries out metabolism to maintain self growth and reproduction, and meanwhile, organic pollutants are degraded, in the aerobic pool, part of ammonia nitrogen is removed through biosynthesis, and part of ammonia nitrogen is converted into nitrate and nitrite under the action of high-efficiency nitrifying bacteria generated by domestication, and is reduced into nitrogen to be discharged, so that the aim of biological denitrification is fulfilled.
Use the suction pump to take out outside landfill leachate to inside by the micro-filtration outside, get into the micro-filtration at last and produce the water tank, hold back great particulate matter, suspended solid and biological bacterial through tiny gap, will adhere to the suspended particulate matter on the micro-filtration filter through the backwash and wash totally, when the filtering material layer of rivers through quartz sand filter that contain the suspended particle, the filtering material gap plays the screening effect to the suspended particulate matter and makes the suspended solid easily adsorb on the filtering material surface. The effluent after microfiltration and sand filtration has better water quality, but part of refractory organic matters cannot be removed, and the ammonia nitrogen content is slightly higher than the discharge requirement, so that the refractory large molecular organic matters are further separated by nanofiltration, the COD (chemical oxygen demand) and ammonia nitrogen of the effluent meet the discharge requirement, the COD, heavy metal ions and multivalent non-metal ions meet the effluent requirement, and finally, the effluent is subjected to reverse osmosis treatment, the operating pressure of the reverse osmosis is 1.5-10.5 MPa, and the interception component is (1-10) x 10-10m small molecular solute and water are divided into two parts after passing through a reverse osmosis membrane: the treated percolate (effluent) and trapped fluid (concentrated solution) further obtain the treated water which reaches the discharge standard.
further, an aeration fan is adopted when aerobic treatment is carried out in the fourth step. The utilization rate of oxygen can be effectively improved by adopting the aeration fan.
further, the reverse osmosis membrane in the seventh step is cleaned by citric acid. The reverse osmosis membrane is easy to exceed the limit or be infected by bacteria after being used for a long time, so the service life of the reverse osmosis membrane can be prolonged by adopting citric acid for cleaning.
