Abstract
A potential of hydrogen (PH) probe type coal mine acid waste water treatment device belongs to the field of waste water treatment. A PH probe (2) is disposed on an adjusting tank (1) with a water inlet and connected to a dosing pump (8) with a metering pump through a programmable logic controller (PLC) control cabinet. The dosing pump (8) with the metering pump is connected to an alkali dissolution device (6), the bottom of the alkali dissolution device is provided with a sedimentation tank, and the alkali dissolution device is connected to a tap water tube network. The adjusting tank (1) is connected to a neutralization reaction tank (4) and a neutralization aeration tank (5) the bottom of which is an aeration system (9). The neutralization aeration tank (5) is connected to a flocculation reaction tank, and a fan (7) is connected to the aeration system (9). The waste water treatment device is used for coal mine acid waste water treatment, and automatic control replaces manual operation. PH probe signals are transmitted to the PLC control cabinet which controls the metering pump to add in neutralization medicaments, thereby increasing chemical dosing precision and reducing human input.

Coal seam, colliery sulphur content decision waste-water from coal mine character, waste-water from coal mine has the branch of soda acid, in handling acid waste-water from coal mine, because coal mine institute effluent water quality has unstable, its pH value changes greatly, artificially control adder-subtractor in waste water, add in and the medicament difficulty bigger.
Summary of the invention:
The purpose of this utility model is to provide a kind of pH sonde-type colliery acid waste water treatment unit, utilize this device to carrying out automatization control with the medicament dosing system in the acid waste water of colliery, to alleviate sewage works operative employee labour intensity, realize the sewage works automated operation.
Formation of the present utility model: a kind of pH sonde-type colliery acid waste water treatment unit, comprise equalizing tank, the pH probe, the PLC housing, the neutralization reaction pond, in and the aeration tank, molten alkali device, blower fan, the dosing pump of band volume pump, aerating system, have and establish the pH probe on the equalizing tank of water-in, the pH probe is connected by the dosing pump of PLC housing with the band volume pump, the dosing pump of band volume pump is connected with molten alkali device, molten alkali bottom of device is established settling tank, and be connected with the tap water pipe network, equalizing tank and neutralization reaction pond, in be connected with the aeration tank, in and aeration tank bottom be aerating system, in and the aeration tank connect flocculation tank, blower fan is connected with aerating system.
Compared with the prior art, the utility model is used for colliery acid waste water to be handled, and can automatization control substitute manual operation, the pH probe signal transfers to the PLC housing, during PLC housing control volume pump adds and medicament, improve the dispensing precision, reduce human input.
The utlity model has following characteristics:
(1), at first obtain waste water ph, the pH probe transfers to the PLC housing with signal, sends instruction by the PLC housing again by pH probe, during the control volume pump adds and medicament to regulate waste water ph, guarantee the dispensing precision;
(2), PLC housing control agent that volume pump is offerd medicine is adjusted to waste water ph and is beneficial to carrying out in order of subsequent treatment process between the 7-8;
(3), this device realizes unattended operation fully, labour intensity is low; The operative employee only need guarantee have sufficient medicament to get final product in the drug dissolving tank, has saved the investment and the medicine consumption of owner's manpower greatly;
(4), the native system aeration establishes device, but the ferromanganese ion in the efficient oxidation waste water guarantees the water outlet effect;
(5), easy to maintenance;
(6) no oil consumption, anhydrous consumption, no gas consumption, power consumption is few, and main power consumption point is a dosing pump, and because added amount of chemical is less, generalized case is in 100L, and the dosing pump installed power is less.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model,
