Description
Technical field
The invention belongs to useless (dirt) water-treatment technology field of chemical industry, particularly relate to a kind of activated sludge culture method for chemical wastewater treatment.
Background technology
The aboundresources such as Xinjiang Coal, oil, non-ferrous metal and shortage of water resources, there is water resources and the irrational contradiction of other resource distributions, water resources is the important restriction factor of restriction Economy in Xinjiang society great-leap-forward development, current urgent need, by waste water reclaiming, solves the problem of Xinjiang water resource shortage.
Secondary biochemical treatment mainly removes chemical oxygen demand (COD) in waste water (CODcr), biochemical oxygen demand (BOD) (BOD
5).Usual waste water reaches the object of waste water recycling and resource utilization after secondary biochemical treatment by tertiary treatment.The economic pattern in Xinjiang is mainly based on petroleum and petrochemical industry, Coal Chemical Industry, chemical industry for making chlorine and alkali, cotton spinning fiber printing-dyeing, mineral products exploitation etc., and these industries have the advantages that water loss is large, discharge water pollution concentration is high, treatment for reuse difficulty is large.At present, the wastewater treatment of most domestic chemical enterprise, adopting with biochemistry is the treatment process of core, and is aided with advanced treatment process, to reach reuse requirement.But this type of technique mesophytization section exists some problems: (1) biological degradation is not thorough, and the foam of generation is many, a large amount of new water to carry out froth breaking, but weak effect; (2) the wastewater treatment residence time is long, and because hard-degraded substance residual in water is more, the colority of water after process is higher, and variation water quality is comparatively large, is unfavorable for follow-up recycling.
The general acclimation method of active sludge is divided into according to adding bacterial classification: 1. add active sludge, when breeding is to predetermined settling ratio, adds actual waste water blast aeration, by taming step by step to full dose on a small quantity.2. add specified strain, after first putting the breeding of small incubation case hyperalimentation fluid into, the pond that then has high input is bred and is reached required settling ratio.Be divided into according to cultivation domestication program: 1. synchronized culture domestication, while namely cultivating active sludge with ight soil water or sanitary sewage, add trade effluent to be processed.2. asynchronous cultivation domestication, namely first cultivate active sludge with ight soil water or sanitary sewage, the mode that then concentration gradient increases progressively adds trade effluent, until active sludge reaches required settling ratio.In the prior art, once patent report was had to cross the cultivation acclimation method of several microorganism, as " a kind of screening of sea pollution by oil microorganism species and acclimation method and application " (Authorization Notice No. CN102433260B), be a kind of for the reparation of sea pollution by oil wastewater biological, but be not suitable for the domestication of Sewage Plant microorganism." a kind of preparation of oil removing microbial inoculum and the method for this oil removing microbial inoculum process oilfield sewage " (application publication number CN102876574A), be screened specific bacterial classification, method does not have general applicability.

During use, 1:1 is pressed in biologic detoxication agent and bioactive P, dilute with water 10 times, drips continuously at biochemistry pool feed-water end.
Concrete practice is verified: Xinjiang Guang Hui new forms of energy coal chemical industrial wastewater processing system, its biochemical processing process section order is followed successively by: UASB, hydrolysis acidification pool, contact-oxidation pool, CASS, BAF, but Biochemical Treatment is very poor, waste water for a long time can not be up to standard.Wherein, CASS pond has a large amount of foam to produce, and has a large amount of suspended substances, causes BAF to block, and active sludge color is Vandyke brown, microscopic examination, finds a small amount of beans shape worm, flagellate and erythema Hubei Province body worm, but basic outage, activity is very low.According to Site Detection record analysis (design water outlet CODcr68mg/L, oil-contg 5.9mg/L, actual water outlet average CODcr 180.73mg/L, oil-contg 15.9mg/L), select the active sludge in CASS pond as the object cultivating domestication, and be equipped with biologic detoxication agent and bioactive P.Concrete operation step is as follows: (1) domestication process adopts the mode of continuum micromeehanics water outlet to carry out, and temperature controls at 30-37 DEG C, continuous aeration, and dissolved oxygen remains on 2-5mg/L; (2) the influent COD cr concentration in CASS pond is 300 ~ 600mg/L, oil-contg 10 ~ 30mg/L.Biologic detoxication agent and bioactive P dilute with water 10 are accompanied, and in CASS pond, feed-water end drips continuously, and the first stage adds biologic detoxication agent and bioactive P, and dosage is 7mg/L, and the time is 11 days.Subordinate phase adds biologic detoxication agent and bioactive P 5mg/L, and the time is 15 days.Before adding biological growth promoter and biologic detoxication agent to CASS pond, CASS pond water outlet CODcr mean value is 180.73mg/L, oil-contg mean value 15.9mg/L.Add the first stage of medicament, the impact that system is subject to water quality impact is less, and CODcr and the oil-contg mean value of water outlet are respectively 120.45mg/L, 8.96mg/L.Add the subordinate phase of medicament, aeration tank water outlet CODcr and oil-contg mean value are respectively 60.33mg/L, 1.23mg/L.
Conclusion: this illustrates after adding medicament, and biological activity is enhanced, and the organic ability of microbiological deterioration is improved, system run all right.From continuous microscopy, before biologic detoxication agent and bioactive P use, find that in CASS pond, zoogloea appearance profile is not obvious, loosely, and flco is less, finds a small amount of beans shape worm, flagellate and erythema Hubei Province body worm for sludge structure, but basic outage, activity is very low.This phenomenon shows, CASS pond toxic material concentration is higher, and the mud that is in CASS pond is in toxic state.Adding after biologic detoxication agent and bioactive P subordinate phase terminate, microscopy finds, mud flco increases, edge clear, close structure, has protozoon and metazoan kind to increase, active grow.Also can find out adding of medicament from biophasic change, reach desired result.
