System, counter-infiltration system is connected to Fenton oxidation system and clear water reserviors.
It is preferred that, the pretreatment unit includes coagulation reaction tank, the preliminary sedimentation tank being sequentially connected.Ensure that biochemical system is stable
Operation, it is necessary to pre-processed to agricultural chemicals waste water.Coagulation reaction tank adds PAC, PAM and is used as coagulant.
It is preferred that, the preliminary sedimentation tank is connected to sludge treating system, and the sludge treating system includes sludge concentration tank, dirt
Mud conditioner and plate and frame filter press, the liquid circulation that the sludge treating system is produced are fed in regulating reservoir.Such sheet frame
The dewatered sludge that filter press is made can send utilization outside.
It is preferred that, the anaerobic system is EGSB anaerobic reation pools.In the reactor, suitable pH and at a temperature of enter
Organic matter in row anaerobism, sewage is decomposed by anaerobic bacteria to be utilized, and macromolecule organic changes into the VFA of small molecule
And methane, partial contamination material is converted into water and carbon dioxide, while biogas is produced, finally by the three-phase separate in reactor
Gas-solid-liquid is carried out from device to be separated.
It is preferred that, the A/O systems include A/O ponds, second pond.Using A/O processing systems, COD and NH is removed3-N。
It is preferred that, the A/O systems are connected to sludge treating system.
It is preferred that, the Fenton oxidation system includes conditioner, Fenton oxidation pond, reaction tank, neutralization precipitation pond.It is logical
Fenton oxidation system reduction waste water COD is crossed, while destruction has the structure and activity of inhibitory action material, such as dichloro to microorganism
The materials such as methane, methanol, bromide.
It is preferred that, the neutralization precipitation pond is connected to sludge concentration tank.
It is preferred that, oil interceptor is provided with regulating reservoir.Enter before regulating reservoir and to be handled by oil interceptor, remove the grease type in waste water
Material.
Set, after the utility model is pre-processed by coagulation reaction tank, handled through preliminary sedimentation tank by such, waste water is through pre-
Enter subsequent biological treatment device after processing, biological treatment mainly uses " EGSB anaerobic reactions+A/O " facture, then by anti-
Osmosis system and Fenton oxidation system further handle qualified discharge, and whole course of reaction is simply efficient, resource weight in system
It is multiple to utilize, reduce the cost of operation.
Brief description of the drawings
Fig. 1 is a kind of structural representation of agricultural chemicals waste water processing system of the utility model.
Embodiment
As shown in Figure 1：Behind the adjusted pond of the utility model waste water, into aftertreatment systems.Entering biochemical treatment system
Before system, in order to ensure biochemical system stable operation, it is necessary to which agricultural chemicals waste water is pre-processed.The coagulating conduct of this process choice
Pretreatment measure, reduction waste water COD and SS.
Contain grease, organic solvent class material wherein in agricultural chemicals waste water, enter before regulating reservoir and to be handled by oil interceptor, remove useless
Oil substances in water.
Regulating reservoir waste water first passes through the medicaments such as coagulation reaction tank dosing coagulant, flocculant, removes COD and SS, then through first
Heavy pond mud-water separation, preliminary sedimentation tank water outlet enters subsequent biological treatment.Waste water enters subsequent biological treatment after materialized pretreatment and filled
Further processing qualified discharge is put, biological treatment mainly uses " EGSB anaerobic reactions+A/O " facture.Waste water is through EGSB anaerobism
Reaction tank, further removes organic solvent class material, reduces waste water COD.In the reactor, suitable pH and at a temperature of enter
Row anaerobism, the organic matter that macromolecule organic is changed into the VFA and methane of small molecule, sewage is by anaerobic bacteria point
Solution is utilized, and most of polluter is converted into water and carbon dioxide, while biogas is produced, finally by the three-phase in reactor
Separator carries out gas-solid-liquid and separated.In A/O systems microorganism live in the alternate environment of anaerobic-aerobic and by
Screening.A sections of main function is that microorganism fungus kind is screened and optimized, and microorganism is in this section simply to organic in waste water
