Description
Technical field
The utility model relates to sewage treatment area, specifically refers to a kind of waste water treatment system for nursery of resource utilization.
Background technology
In the last few years, China's aquaculture development was rapid, and the plant that sets up mass-producing has become the development trend of current aquaculture.Modern plant is stricter to hygienic requirements, usually produces a large amount of flushing waste waters.These flushing waste waters usually contain a certain amount of excrement slag, and very easily breed bacteria and virus, discharge if just dealt with improperly, very easily cause that plant livestock falls ill on a large scale, causes great loss.Existing waste water treatment system for nursery conventionally only carries out disinfection before discharge, has ignored bacterium and virus in wastewater treatment process and may breed once again and propagate, and causes livestock morbidity.Particularly, first existing waste water treatment system for nursery utilizes grid filtration macrobead suspended substance conventionally, and the main component of these macrobead suspended substances is ight soil, with a large amount of pathogenic bacterium, easily causes livestock morbidity.
Utility model content
Thereby being to provide a kind of, the purpose of this utility model can prevent bacterium and the viral waste water treatment system for nursery of breeding once again and propagate the resource utilization that causes livestock morbidity in wastewater treatment process.
The utility model is achieved through the following technical solutions:
A kind of waste water treatment system for nursery of resource utilization, system is disinfecting tank foremost, system least significant end is sterilization pool, between disinfecting tank and sterilization pool, be provided with the marsh gas fermentation pool, plate-and-frame filter press, equalizing tank, contact-oxidation pool, settling tank, the activated carbon adsorption tank that connect successively, marsh gas fermentation pool is connected with disinfecting tank, activated carbon adsorption tank is connected with sterilization pool, and settling tank is tube settler.
Further, described marsh gas fermentation pool is connected with disinfecting tank by acid-alkali accommodation pond.By acid-alkali accommodation pond, not only can eliminate plant waste water and impact the impact on marsh gas fermentation pool fermentation, can also eliminate the impact on microorganism growth breeding in marsh gas fermentation pool of the disinfecting drug taken out of from disinfecting tank.In addition, by acid-alkali accommodation Chi Kejiang plant waste water pH-value, be adjusted to suitable marsh gas fermentation pool and ferment, thereby the speed of quickening biogas fermentation reduces the treatment time of plant's waste water in marsh gas fermentation pool.
Further, also comprise thionizer, activated carbon tower and gas-holder, described thionizer is connected with marsh gas fermentation pool, and described activated carbon tower is connected with thionizer, and described gas-holder is connected with activated carbon tower.By thionizer, can carry out desulfurization processing to the biogas producing in marsh gas fermentation pool, produce desulfurization biogas.Activated carbon tower can be dry except water deodoring by desulfurization biogas, obtains dry desulfurization biogas.Dry desulfurization biogas just can be as commodity selling after being stored in gas-holder, and the sale of commodity brings economic benefit can to plant's wastewater treatment, reduces plant's wastewater treatment expense.
Further, also comprise sludge drying bed, described sludge drying bed is connected with plate-and-frame filter press.Plate-and-frame filter press, when fermented waste fluid being carried out to solid-liquid isolation, has produced excrement slag.Excrement slag obtains compost after processing by sludge drying bed, and compost is good fertilizer, can be used for selling.Compost is sold will bring certain economic benefit to plant's wastewater treatment, thereby can reduce plant's wastewater treatment expense.
Further, described contact-oxidation pool is connected with deamination pond.At present, China adopts chlorine or oxychloride to sterilize to discharge water conventionally.But ammonia nitrogen concentration is high in plant's waste water, if directly use chlorine or oxychloride to carry out disinfection, easily produce chloramines, waste disinfecting drug, causes disinfection cost to rise.By setting up the deamination pond being connected with contact-oxidation pool, the denitrification in the nitrification of contact-oxidation pool and deamination pond loops, can be nitrogen and nitrate by the mineralized nitrogen in plant's waste water, reduce the use of follow-up sterilization pool disinfecting drug, reduce disinfection cost.
Further, also comprise chlorine dioxide generator, described chlorine dioxide generator is connected with sterilization pool.Dioxide peroxide is a kind of novel powerful disinfectant, and its sterilization and disinfection ability is that existing chlorine is 3-5 times of sterilizing agent, has the advantages such as efficient, safe.Dioxide peroxide does not only produce carcinogenic halogenide in sterilization and disinfection process, can also remove the peculiar smell in water, and disinfection cost is low, is the desirable medicament of existing plant wastewater treatment sterilization and disinfection.By being connected of chlorine dioxide generator and sterilization pool, can accomplish to produce on one side, use on one side, reduced the waste of dioxide peroxide in preservation process.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) first the utility model carried out disinfection to plant's waste water by disinfecting tank before wastewater treatment, thereby not only avoided bacterium in plant's waste water and virus to breed once again and propagate, cause livestock morbidity in wastewater treatment process, can also eliminate bacterium and the restraining effect of virus to microorganism growth breeding in marsh gas fermentation pool in plant's waste water;
(2) the utility model by setting up acid-alkali accommodation pond between disinfecting tank and marsh gas fermentation pool, not only can eliminate plant waste water and impact the impact on marsh gas fermentation pool fermentation, can also eliminate the impact on microorganism growth breeding in marsh gas fermentation pool of the disinfecting drug taken out of from disinfecting tank;
(3) the utility model, by setting up the deamination pond being connected with contact-oxidation pool, not only can make water outlet ammonia-nitrogen content up to standard, can also reduce the use of sterilization pool disinfecting drug, reduces processing cost.
