Abstract
The invention discloses a comprehensive treatment method for livestock dirt. The method comprises the following steps of: a, collecting solid manure and liquid manure of pigs in an anaerobic tank for anaerobic treatment; b, feeding the solid manure and the liquid manure which are subjected to anaerobic treatment into an aeration tank for aerobic treatment; and c, settling the solid manure and the liquid manure which are subjected to aerobic treatment, and performing slag-liquid separation. The solid manure and the liquid manure of the pigs are collected and settled in the anaerobic tank, are subjected to anaerobic treatment and aerobic treatment, and then are completely purified through electrolysis treatment, so that the content of chemical oxygen demand determined by a potassium dichromate method (CODcr), biochemical oxygen demand (BOD5) and suspended solids (SS) in the liquid manure can be greatly reduced; and meanwhile, the electrolytic reaction can eliminate heavy metal ions in the liquid manure and can further improve the purification effect of the liquid manure, so that the ecological pollution caused by heavy metal substances when the liquid manure is discharged or recycled after being purified is avoided.
Description
Technical field
The present invention relates to a kind of sewerage treating method and device, particularly the integrated conduct method of a breeding stock dirt and device.
Background technology
In livestock breeding industry, drain the dirt and the waste water that produce by animals such as pig, ox, birds and belong to high concentration organic sewage, big characteristics that it has the organic concentration height, suspended substance is many and the water yield fluctuates.If these wastes are concentrated discharging or are dealt with improperly, not only cause a large amount of losses of available stock, reduce economic benefit, and bring havoc to agroecological environment.
Prior art is handled the method for excrement dirt, normally adopt processes such as filtration, precipitation, solid-liquid separation, biochemical treatment successively, final chemical oxygen demand (COD) (CODcr), biochemical oxygen demand (BOD) (BOD5), suspended substance (SS), ammonia nitrogen (NH3-N) equal size that reduces in the sewage is to reach " livestock and poultry breeding industry pollutant emission standard " (GB18596-2001) specified standards.
See also in the first phase in 2007 " Chinese milk cow " 49～51 pages, " the simple and easy technology of stock-farms sewage disposal is probed into " literary composition, article numbering: 1004-4264(2007) 01-0049-03, a kind of processing solid-liquid separation process sewage is later on disclosed, adopt anaerobic treatment method, oxygen consumption oxygen facture, and waterplant pool handling procedure, by plash, solid-liquid separation tank, hydrolysis acidification pool, anaerobic pond, aeration tank and the settling tank that matches, the waterplant pool, artificial swamp, make sewage be purified preferably, particular case is as follows:
A, at first carry out solid-liquid separation by plash, solid-liquid separation tank and hydrolysis acidification pool and handle;
Realize that filtration, precipitation and solid-liquid separation, the CODcr in the dirt can remove 60%, BOD5 can remove 50%, SS can remove 60%;
B, carry out anaerobic treatment by anaerobic pond;
In anaerobic pond, the organism generation chemical reaction in the sewage generates gases such as NH3-N, H2, CO, and after desulfurization etc. is handled as energy utilization.
C, carry out aerobic treatment by the aeration tank;
Carrying out oxygenation in the oxygen pond of exposing to the sun handles, sewage is fully contacted with air, increase the dissolved oxygen amount in the water, the organism that does not have to decompose at upper level is further decomposed in aerobic environment, further promote the abundant oxidation of the sewage behind the anaerobically fermenting, and impel aerobic microbiological further to consume CODcr, BOD5 and SS in the sewage.
D, carry out post-processed by the waterplant pool, artificial swamp etc.;
Plant itself can absorb the nutritive substance in the sewage, this can make sewage be purified to a certain extent, the oxygen that plant is made under photosynthesis gives sewage oxygenation for microbial respiratory by root system simultaneously, and root system micro-flora and enzyme can also be degraded, the mineralising organism.
In addition, SS is trapped in the sewage, makes sewage obviously become clear through water quality behind the waterplant pool.
But it still has the following disadvantages:
1, in the sewage after the employing aforesaid method is handled, the content of chemical oxygen demand (COD), biochemical oxygen demand (BOD), suspended substance is still higher, though can satisfy emission standard, but still be not enough to satisfy the demand of recycling;
2, owing in the livestock industry, contain heavy metal contaminants such as Cu, Zn in the additive of animal feed, the sewage after aforesaid method is handled still contains more heavy metal contaminants;
3, the sewage after the employing aforesaid method is handled, the content of intestinal bacteria and other bacteriums is still higher, enters river or occurring in nature and can cause pollution of waterhead, forms pestilence easily.
4, the solid dirt after solid-liquid separation and the anaerobic treatment owing to lack drying plant, fuel cost height, directly discharges the solid excrement material that originally can dry as waste material usually, and utilization ratio is lower.
Summary of the invention
The objective of the invention is to overcome existing above-mentioned deficiency in the prior art, the integrated conduct method of a kind of good purification, poultry dirt that pollutant load is few is provided;
Further, provide a kind of integrated conduct method that can significantly reduce the poultry dirt of heavy metal, intestinal bacteria and other bacteria contents in the pig dirt waste water;
Further, provide a kind of integrated conduct method that takes full advantage of the poultry dirt of anaerobic treatment and solid dirt.
Another goal of the invention of the present invention is: a kind of good purification, poultry dirt waste water one treatment unit that pollutant load is few are provided;
Further, provide a kind of poultry dirt waste water one treatment unit that can significantly reduce heavy metal, intestinal bacteria and other bacteria contents in the pig dirt waste water;
Further, provide a kind of inflammable gas that anaerobic treatment forms, and poultry dirt waste water one treatment unit of livestock and poultry solid dirt of taking full advantage of.
