Abstract

The invention discloses a production method for active carriers used in sewage biological denitrification. The production method comprises the following steps: 1, selecting corallite bone black and plastic carriers; 2, conducting microbial carrier cultivation: artificially preparing wastewater, adding pond sludge into a container for mixing, adding corallite for aeration cultivation at 25-30 DEG C for 10-15 days, and adopting the Nessler's reagent method to detect ammonia nitrogen to show whether carrier bacteria generate or not; 3, conducting carrier enlarging cultivation: mixing cultivated nitrifying bacteria carriers with neosoma in a ratio of 1:3 for enlarging cultivation according to the carrier bacteria enlarging cultivation method; 4, completing the production when the removal rate of carrier ammonia nitrogen (8.0 mg/L) obtained is greater than 85%, and the nitrifying rate is greater than 8.0 kg/(m<3>.d) by adopting the method.

Description

A kind of production method of bio-denitrifying sewage active carrier
One, technical field
The present invention relates to a kind of production method of bio-denitrifying sewage active carrier.
Two, technical background
Polluted by nitrogen is to cause body eutrophication major reason, and the object of processing is to reduce nitrogen content.Water body denitrification method has physical adsorption, chemical reaction, coagulating sedimentation and biological denitrificaion etc., and biological denitrificaion is maximum with nitrated-denitrification combined utilization.Because remarkable, the simple to operate construction costs of the reliable effect of technology is low, do not cause secondary pollution.Be widely applied.
Adopt at present the method for biological denitrificaion to have A/O, A 2the technology that/O, SBR gather mutually with short distance nitration and Anammox, these are all the zoogloea of using microbe formation and the mud group of thread fungus and microfauna formation.Aspect experimental study, obtaining good result, still there is defect in various degree in the application of mass-producing.
Someone uses the fixedly bio-denitrification technology such as embedding, bio-carrier, material has biocycle and ball, porous insert, haydite, soft and elastic filler, the smooth surface that this class material has is unfavorable for that nitrifier adheres to and grows, and what have does not meet drinking water hygiene requirement, and overall rate of nitrification is not high.
Due to A/O and A 2/ O technique self exists carbon source competition, nitrated incomplete, heavy pond to float the factors such as mud, sludge bulking, mud Age ratio control, ammonia nitrogen qualified discharge inhuman meaning after denitrogenation.Water environment pollution can not get effectively administering and occurring eutrophication.Cast Some Lakes wawter bloom red tide of sea, cause many harm to industrial and agricultural production and people's life.
Biological denitrificaion is to utilize the effect in nitrogen cycle of nitrification and denitrification bacterium in physical environment.Low according to nitrifier capacity usage ratio, poor growth, the breeding cycle is long is obligate autotrophy bacterium, usings oxygen as final electron acceptor(EA) and obtain the needed energy of growth in oxidising process, can not on organic substratum, grow.The problem and the bio-denitrification technology requirement that based on this and sewage disposal, exist, the present invention is the nitrifier that screening one strain has efficient denitrification ability, being cultivated domestication increases bacterium and depends on the carrier of suitable growth breeding, growth and breeding under artificial condition, making it is that maximum rate of nitrification is brought into play in Engineering Service.
Three, summary of the invention
The object of the present invention is to provide a kind of production method of bio-denitrifying sewage active carrier, the production method of this active carrier is to be undertaken by following process:
1, select materials: 1. select high-quality corallite shell and bone black, granularity requirements 3-8mm; 2. plastic carrier is that corallite shell and bone black are crushed to separately and can merge mutually and be processed into thread or velutinate carrier with plastics;
2, carrier carries bacterium and cultivates: artificial wastewater's preparation, with 2 liters with 2.0 grams of upper container chlorination ammonia, 1200 milliliters of ordinary waters, with sodium carbonate adjust pH 7.5-8.0, add 200 grams, settling tank mud, be mixed, add 1000 grams of corallites, under the condition of 25-30 ℃, aeration is cultivated 10-15 days.If ammonia nitrogen is reduced to zero continuing and added ammonium chloride, pH value adds sodium carbonate lower than 7.0 and is adjusted to regulation.By nessler reagent colorimetric determination ammonia nitrogen situation, to judge whether carry thalline generates with qualified;
3, carrier enlarged culturing: wash away mud by cultivating nitrifier carrier appropriate and domestication, in mixing with 1: 3 ratio of corallite, carry bacterium cultural method expanding species by carrier;
Clearance > 85% when the carrier ammonia nitrogen that 4, this law is produced is 8.0mg/L.The nitrated rate of volume is greater than 8.0kg/ (m 3.d).
