Description
Technical field
The present invention relates to a kind of kitchen garbage, waste-water treatment technology, especially a kind of kitchen garbage, waste-water preprocessing system.
Background technology
People will produce various waste rubbish constantly in urban life, wherein rubbish from cooking refers to the rubbish that kitchen process food materials are remaining, it is various based on the rubbish of discarded fruits and vegetables that fruits and vegetables rubbish mainly refers to that fruit and vegetable market produces, and it is main feature that two kinds of rubbish all have organism.Because domestic technology of garbage disposal still processes more rudimentary developmental stage, more than existing kitchen, classification process generally do not done by fruits and vegetables rubbish, transport to refuse tip landfill together with common rubbish, such process can cause great environmental pollution, the percolate that not only generates can polluted underground water, and the biogas produced and strong smell can have a strong impact on life and the health of people.But in fact the overwhelming majority is organism and thermal source in fruits and vegetables rubbish more than kitchen, reclaim bio-energy after slurrying can be considered again to utilize, reduce people to naturally asking for and consuming, great meaning will be had to protection environment for human survival.
Applicant once designed a kind of changing food waste removal of impurities slurrying all-in-one, and applied for that the patent No. was the utility model of 201330347758.9, simultaneously to the serial local improvement of this machine, had also applied for that series of patents is protected.When this changing food waste removal of impurities slurrying all-in-one uses, kitchen garbage breaking can be obtained the rubbish slurries being rich in biomass and thermal source.Then rubbish slurries are carried out high-temperature anaerobic fermentation process, obtained biogas can be decomposed and Collection utilization, fermentation after residual sludge can dewater after for the production of organic chemical fertilizer.Changing food waste is made to obtain abundant regeneration like this.
But wherein, the leachate waste water deviate from during dehydration, needs ability qualified discharge after sewage disposal; During sewage disposal, applicant considers mainly to adopt SHARON short-cut nitrification and denitrification technique to carry out sewage disposal in conjunction with the mode of MBR Membrane Bioreactor for Wastewater Treatment.But due to the singularity of kitchen garbage, waste-water composition, its contain a large amount of do not decomposed by thermophilic fermentation oil, organism, protein is by the nitrogenous compound that stays after ammonification and dehydration remaining levitation thing etc.Have that the water yield is large, draining is uneven, organism and ammonia nitrogen concentration is high, impurity and suspended substance many, the feature of good biodegradability is a kind of high concentrated organic wastewater.Therefore only lean on SHARON short-cut nitrification and denitrification technique in conjunction with the mode of MBR Membrane Bioreactor for Wastewater Treatment, still cannot meet the requirement of kitchen garbage, waste-water process.Need to design preprocessing system targetedly, improve wastewater treatment efficiency, can emission compliance.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention is, how to provide one can realize the effects such as oil removing, adjustment and scum silica frost cleaning, to improve the kitchen garbage, waste-water preprocessing system of the final treatment effect of waste water.
In order to solve the problems of the technologies described above, in the present invention, have employed following technical scheme:

Described kitchen garbage, waste-water preprocessing system comprises oil partiting precipitation pool, equalizing tank and Demulsification and coagulant air supporting deslagging device, one end of described oil partiting precipitation pool is provided with rubbish fermentation wastewater inlet pipe, the other end is connected with equalizing tank by outlet conduit, is provided with oil slick removal device in oil partiting precipitation pool; Described equalizing tank one end is the feed-water end be connected with the outlet conduit of oil partiting precipitation pool, the other end is water side and water side is connected with Demulsification and coagulant air supporting deslagging device with water outlet riser tubing by lift pump, position, equalizing tank water side is also provided with temp probe and apparatus for controlling water exit temperature, temp probe position and water outlet riser tubing water inlet position correspondence; Described Demulsification and coagulant air supporting deslagging device comprises a horizontally disposed accommodating body, accommodating body one end is connected with the water outlet riser tubing of equalizing tank water inlet, the other end is provided with waterwall near end position, the upper lateral part of waterwall in the face of accommodating body water inlet position is provided with removing dross groove, the side of removing dross groove face to accommodating body water inlet position is return side, scum silica frost groove sidewall is provided with scum silica frost outflow pipeline, waterwall forms out hydrospace back to the side of accommodating body water inlet position and is provided with outlet conduit, waterwall is positioned at below removing dross groove and is provided with water hole;
Waste water after b, pre-treatment is sent to SHARON pond, adopts sequencing batch operation mode to carry out short distance nitration denitrogenation processing, is discharged to sludge sump outside the mud of generation;
Waste water after the process of c, SHARON pond is drained into UVHSB bio-reactor and is hydrolyzed acidification, removes some organic pollutants in waste water, improves wastewater biodegradability, macromolecule contaminant in waste water is degraded to small molecule contaminants to produce sufficient carbon source;
Waste water after c, UVHSB bioreactor for treatment is by after receiving mill weir and collecting, and gravity flow enters MBR membrane biological reaction pond and carries out nitration denitrification and membrane biological reaction process in an overflow manner, completes whole waste water processes.
