Description
Technical field
The invention belongs to environmental technology field, be specifically related to a kind of method of processing sanitary sewage.
Background technology
Sanitary wastewater is the sewage producing in human lives's process, is one of primary pollution source of water body.Mainly ight soil and wash water.The sanitary sewage amount that discharge everyone every day in city is 150-400L, and its amount has substantial connection with standard of living.In sanitary sewage, contain large amount of organic, as Mierocrystalline cellulose, starch, carbohydrate and fat protein etc.; Also often contain pathogenic bacteria, virus and parasitic ovum; The muriate of inorganic salts, vitriol, phosphoric acid salt, supercarbonate and sodium, potassium, calcium, magnesium etc.Total feature is nitrogenous, sulfur-bearing and phosphorous height, and post-processed is more difficult.People should water conservation. and China's actual conditions are more special, and water resources occupancy volume per person is few, and spatial distribution is uneven.Along with Chinese Urbanization's, industrialized acceleration, the demand gap of water resources also increases day by day.Under such background, sewage treatment industry becomes new industry, at present and tap water production, water supply, draining, middle water reuse industry in status of equal importance.
Although municipal aspect has dropped into a large amount of funds and administered sewage, prior art also has many methods can effectively remove ammonia, as physical method has reverse osmosis, distillation, soil irrigation; Chemical method has ion exchange method, ammonia stripping, chemical precipitation method, breakpoint chlorination, electrodialysis, electrochemical treatment, catalytic pyrolysis; Biological method has nitrated and algal culture, yet physical method treatment effect is not good, than chemical method, biological method is processed waste water and is had the following advantages: 1) every kind of chemical article is all the product that specific aim is very strong, when running into other chemical substances, just likely lost efficacy, and biotechnological formulation has spectrum to the removal of pollutent; 2) chemical products can temporarily be eliminated some objectionable impurities and mask malodors, but can not stop the generation of objectionable impurities; 3) use after chemical products, in water body, have residually, may cause secondary pollution.The contained natural microbial of biotechnological formulation,, containing pathogenic bacterium and pathogenic agent, these microorganisms are not under the katalysis of enzyme, the organic nutrient substance of take in sewage is food, after sewage is purified, these microbes reduce gradually with the reduction of pollutent, until wither away; 4) nontoxic, non-corrosiveness, easy to use, substantially do not need interpolation equipment or engineering, save fund input.Yet microbial process is disposed of sewage and easily caused the secondary pollution of microorganism to water body, how microorganism being processed is also the technical issues that need to address.In field of Environment Protection, how sanitary wastewater is purified, and reach emission standard and recycling is the technical issues that need to address.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of technique of processing sanitary sewage.Technology of the present invention has adopted complex microorganism preparations, environment friendly and pollution-free, and utilizes discarded microorganism to prepare organic fungi-manure, and whole technological process produces without extra pollutent, has realized and having turned waste into wealth.
The present invention adopts following technical scheme to realize:
A method of processing sanitary sewage, it comprises the steps:
Prepare microbial preparation: mixed bacteria liquid, kaolin and wheat bran are mixed according to the weight ratio of 2:1:1, stir, then put cryodrying at 4 ℃, dry rear water content is controlled at 5%, obtains; Described mixed bacteria liquid is mixed by the raw material bacterium of following parts by volume: subtilis 8-10 part, colloid bacillus cereus 6-7 part, aspergillus niger 5-6 part, 3 parts of rhodococcus, thiobacillus denitrificans 2,1 part of 2 parts of bacillus cereuses and Sphingol single-cell; The concentration of above-mentioned raw materials bacterium is all controlled at 3-5 * 10
7individual/ml.
Preliminary impurity-removing precipitating: sanitary sewage, successively by grid and mud, reclaims solid matter, can be used as ferment preparation of sludge gas preparation; Then sewage enters settling tank, and standing 12 hours, wherein, the bottom filling of settling tank was the river sand of 100cm thickness, and the particle diameter of river sand is 1mm, can some flocculated impurities tentatively be adsorbed and be precipitated;
Advanced sewage purification: be drained into treating pond through settling tank oettIed sewage, then regulating pH is 7-8, by every cubic metre of liquid, add 10 grams of microbial preparations at every turn, add every day 1 time, add continuously after three days, standing one week again, liquid is filtered by plate filter, finally discharge plate filter filtered and recycled microorganism and tunning thereof, obtain mixture A, for the preparation of bacterial manure;
Organic fungi-manure preparation: maize straw is dried, be then ground into corn stalk powder with pulverizer, add in fermentor tank, then add humic acids, the peat composed of rotten mosses, wilkinite and water, the speed of 1000 revs/min stirred after 15 minutes, standing 7 days, made organic matter; Organic matter is mixed to 10 ℃ of dry, low temperature granulations and get final product according to 10:1 with mixture A; Wherein, the weight ratio of corn stalk powder, humic acids, the peat composed of rotten mosses, wilkinite and water is 3:1:1:1:4; More than corn stalk powder, humic acids, the peat composed of rotten mosses and bentonitic particle diameter are 100 orders.
Bacterial classification of the present invention belongs to conventional bacterial strain, all can buy and obtain from commercial sources such as CGMCC, CCTCC and US mode culture collection warehousings (ATCC).The enlarged culturing of each bacterial classification of the present invention is the cellar culture mode of this area, is not innovative point of the present invention, does not describe in detail herein.
The beneficial effect that the present invention obtains mainly comprises:
Treatment process simple possible of the present invention, input cost is low; When the present invention processes sanitary sewage, prepared organic fungi-manure, avoided a large amount of bacterium and tunning to be discharged in water body and caused secondary pollution, killed two birds with one stone, turned waste into wealth, greatly provided cost savings; The present invention processes in the Technology of sanitary sewage and has mainly adopted microbial process, reasonable compatibility between each bacterial classification wherein, and symbiosis is coordinated, antagonism not mutually, its preparation method is easy, easy to implement the method, and it is easy and simple to handle, is beneficial to suitability for industrialized production; The present invention adopts the raw materials such as agricultural wastes to combine discarded microorganism to prepare organic fungi-manure, turn waste into wealth, greatly provide cost savings; That organic fungi-manure prepared by the present invention can reach is disease-resistant, increase production, improve fruit quality texts, and environment friendly and pollution-free.
