Description
Technical field
A kind of enriched medium for acclimated activated sludge of the present invention, belongs to technical field of waste treatment.
Background technique
Daily use chemicals detergent is household chemicals inseparable in people's daily life, and the application of detergent improves people
Quality of life, China's detergent industry develops comparatively fast in recent years, and yield increases year by year, while expired overstock of business inventory is washed
It is also increasing to wash agent product volume, how to handle and most of daily use chemicals manufacturing enterprises is caused to perplex, be current daily chemical industry urgently
It solves the problems, such as.
Under the overall background of the marketization, expired or overstocked commodities are handled, because daily use chemicals cleaning product is inherently
Containing a large amount of organic carbons, underground water can be impacted by carrying out landfill or emission treatment.And harmless biological processing just become can
The only way of sustainable development, therefore this technology is by tamed strain and screening, using the organic carbon in detergent as carbon source,
Using the degradation technique of microorganism, so that organic carbon constituents such as surfactant, macromolecular chelating agent in detergent is degraded, reach
National emission standard, and associated byproducts are obtained, realize the harmless treatment of expired daily use chemicals detergent product.
Summary of the invention
To solve the shortcomings of the prior art, the invention discloses a kind of enrichment cultures for acclimated activated sludge
Base, the culture medium fertilizer efficiency duration is long, and raw material is easy to get, low in cost.
Technical scheme is as follows:
A kind of expired daily use chemicals cleaning product method for innocent treatment, includes the following steps:
A. mix: by expired daily use chemicals cleaning product liquid charging stock and urea, by expired daily use chemicals cleaning product liquid charging stock and urea,
Fe2+, Mg2+, Mn2+, Co2+, Ni2+, B family vitamin and water are uniformly mixed, mixture are made, so that each ingredient in the mixture
Concentration are as follows: 20~30g/l of expired daily use chemicals cleaning product, urea 5~15g/l, Fe2+5~12mg/l, Mg2+1~5mg/l, Mn2+3
~8mg/l, Co2+40~60mg/l, Ni2+10~20mg/l, 1~5mg/l of B family vitamin；
B. composite flora is added to be inoculated with mixture, so that composite flora concentration is 60~200g/l in the mixture,
Using deflector type zymotechnique, at a temperature of 30-37 DEG C, ferment 5~10 days；
The composite flora includes: the activated sludge 35~50% after domestication, and photosynthetic bacteria 5~10%, methane backeria 20%~30% is withered
Careless bacillus 5%~15%, Trichoderma 5~15%；
C. ferment generation biogas slurry enter settling tank carry out sedimentation separation, supernatant direct emission, biogas residue conduct after drying
The devil liquor recovery of bio-bacterial manure, purifying column uses；
D. ferment the biogas product of generation, pressurizes after purifying column purifies, into gas storage tower, compression, and transport or directly
It uses.
The daily use chemicals cleaning product raw material be solid when, to solid material be crushed rehydration dissolution after, then with urea, Fe2+,
Mg2+, Mn2+, Co2+, Ni2+, B family vitamin and water be uniformly mixed, mixture is made.
The Fe2+, Mg2+, Mn2+, Co2+, Ni2+Addition form be Fe, Mg, Mn, Co, the chloride or sulphur of Ni element
Hydrochlorate.
It is stirred continuously in the fermentation process, and the defoaming agent of 10~50mg/l is added, generated in elimination fermentation process
Foam.
Deamination, carbon dioxide removal, desulfurization and dewatering unit are equipped in the purifying column.
The activated sludge acclimatization method are as follows: take the activated sludge 100- of daily use chemicals cleaning product manufacturer sewage treatment mouth
90~150ml enriched medium is added in 300ml, and culture solution is made in the detergent product of 4-8g, after sealing, by the culture solution
Domestication is cultivated under the conditions of 35~37 DEG C, domestication is divided into 4~6 stages progress, acclimation period 4~6 weeks, daily use chemicals is gradually increased and wash
Wash influence of the products material to activated sludge；The additive amount of the enriched medium gradually halves, and the detergent product adds
Dosage gradually increases, and increases 0.5-2g every time；Last time only adds detergent, does not add enriched medium, until finally making
Daily use chemicals cleaning product additive amount in system reaches 30 ± 2g/l, continues culture 7~10 days, until total organic carbon contains in culture solution
