Abstract
The invention discloses an imidacloprid waste water treating technology and relates to the field of environmental protection. The imidacloprid waste water treating technology comprises the five steps of chemical phosphorus removal, alkaline hydrolysis, ammonia nitrogen air stripping, microelectrolysis and biochemical combination. The method is set out from the water quality characteristics of waste water, the design experience of treatment of degradation-resistant organic waste water including other kinds of pesticide waste water is used for reference, the practicability and the economical efficiency of the selected technology are taken into consideration, the technical route of chemical phosphorus removal, alkaline hydrolysis, ammonia nitrogen air stripping, microelectrolysis and biochemical combination is determined, and finally the quality of the treated water can reach a very high level.
Description
Technical field
The present invention relates to field of Environment Protection, be specifically related to a kind of imidacloprid wastewater treatment process.
Background technology
Provado is efficient with it, the feature of low toxicity, low residue, becomes the representative of agricultural chemicals of new generation, has good market outlook.But but there is no ripe technique to the process of its factory effluent can follow, and the not qualified discharge of this waste water, causes serious pollution to environment.Therefore, not only can remove difficulties and alleviate sufferings for enterprise to the research of Provado factory effluent Processing tecchnics, a kind of effective process means can also be sought for the improvement of high concentration hard-degraded organic waste water.
The feature such as high according to its organic concentration, water quality is complicated, biodegradability is poor, adopts chemical dephosphorization-alkaline hydrolysis-ammonia-nitrogen desorption-light electrolysis-biochemistry combination process to administer this waste water.
Summary of the invention
Problem to be solved by this invention is to provide a kind of imidacloprid wastewater treatment process.
To achieve these goals, the technical scheme that the present invention takes is a kind of imidacloprid wastewater treatment process, comprises the steps:
(1) chemical dephosphorization: utilize precipitation agent process imidacloprid wastewater, is formed insoluble phosphate precipitation, is then removed from sewage by phosphorus by solid-liquid separation;
(2) alkaline hydrolysis: utilize 20%NaOH solution to dissolve in step (1) waste water afterwards, be placed in 30-60 DEG C of thermostat water bath, keeps 1-3h;
(3) ammonia-nitrogen desorption: utilize 20%NaOH solution regulating step (3) waste water ph within the scope of 7-10, recycling oxygen dissolved aerator carries out static stripping, can realize the removal of ammonia nitrogen;
(4) light electrolysis: utilize dilute hydrochloric acid that the water after step (3) is regulated initial pH to 7-10, then be placed in light electrolysis post and carry out static aeration;
(5) biochemical combination: utilize the waste water after active bacteria liquid biofilm treatment step (4) of configuration.
Preferably, the precipitation agent that described step (1) uses is the one in aluminium salt, calcium salt and molysite or arbitrary combination.
Preferably, described step (2) alkaline hydrolysis temperature is 40-50 DEG C.
Adopt technical scheme of the present invention, the present invention is from the water quality characteristic of waste water, use for reference the design experiences of the organic wastewater with difficult degradation thereby improvement comprising other kind agricultural chemicals waste water, take into account the practicality of selected technique, economy, determine chemical dephosphorization-alkaline hydrolysis-ammonia-nitrogen desorption-light electrolysis-biochemistry combination process route, after finally making process, effluent quality reaches very high level.
Embodiment
The technique means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
Embodiment 1:
(1) chemical dephosphorization: utilize precipitation agent process imidacloprid wastewater, is formed insoluble phosphate precipitation, is then removed from sewage by phosphorus by solid-liquid separation;
(2) alkaline hydrolysis: utilize 20%NaOH solution to dissolve in step (1) waste water afterwards, be placed in 45 DEG C of thermostat water baths, keeps 1h;
(3) ammonia-nitrogen desorption: utilize 20%NaOH solution regulating step (3) waste water ph 8, recycling oxygen dissolved aerator carries out static stripping, can realize the removal of ammonia nitrogen;
(4) light electrolysis: utilize dilute hydrochloric acid to regulate initial pH value to 8 in the water after step (3), then be placed in light electrolysis post and carry out static aeration;
(5) biochemical combination: utilize the waste water after active bacteria liquid biofilm treatment step (4) of configuration.
Based on above-mentioned, the present invention is from the water quality characteristic of waste water, use for reference the design experiences of the organic wastewater with difficult degradation thereby improvement comprising other kind agricultural chemicals waste water, take into account the practicality of selected technique, economy, determine chemical dephosphorization-alkaline hydrolysis-ammonia-nitrogen desorption-light electrolysis-biochemistry combination process route, after finally making process, effluent quality reaches very high level.
Obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
