Abstract
The invention discloses a method for treating wastewater. The method comprises the following steps of draining domestic wastewater and workshop wastewater into a primary settling tank, and settling large-particle impurities; draining wastewater into a regulating tank, adding alkaline liquid, and controlling the value of pH (potential of hydrogen) to be 7.5-8.5; conveying the wastewater into a thinning tank by a lifting pump, and adding 10-20L of running water per 100L of wastewater; conveying the obtained wastewater into an anaerobic reactor, and feeding an anaerobic bacteria-loaded filler, wherein the surface area of added filler per 1L of wastewater is 100-200cm<3>, and the reaction time is 24-48h; for the wastewater treated by the anaerobic reactor, enabling the surface liquid to pass through an aerobic reaction tank, and the bottom sludge to pass through a sludge drying tank, pressing the sludge, and discharging, wherein the surface area of added filler per 1L of wastewater in the aerobic tank is 300-500cm<3>, and the reaction time is 24-48h; detecting the water body passing through the aerobic reaction tank, and draining out. Compared with the traditional art, the method has the advantages that the wastewater is acted by combining physical-chemical and biochemical methods, and the national drainage standard is met; the standard water body can be repeatedly used, and the pollution factors are further reduced.
Description
Technical field
The invention belongs to chemical industry environmental protection field, be specifically related to a kind of method that waste water processes.
Background technology
Waste water include sanitary sewage, industrial wastewater and just rain footpath flow into other useless water such as sewer, refer generally to after certain technical finesse can not recycling or one-level pollute after make pure intractability and do not reach the water of certain standard.The COD of combined sewage is high, and containing difficult degradation impurity, relies on single physical chemistry method to be difficult to process up to standard in processing procedure.
Summary of the invention
Goal of the invention: present invention aims to the deficiencies in the prior art, it is provided that a kind of method that waste water processes.
Technical scheme: in order to reach foregoing invention purpose, the present invention is specifically achieved in that a kind of method that waste water processes, and comprises the following steps:
(1) sanitary sewage and workshop sewage are entered preliminary sedimentation tank, carry out large granular impurity sedimentation;
(2) sewage entering regulating reservoir, import alkali liquor, control ph is 7.5 ~ 8.5;
(3) by elevator pump, sewage being imported thinning tank, every 100L sewage adds 10 ~ 20L tap water;
(4) step (3) gained sewage being imported anaerobic reactor, put into the filler of load anaerobe, it is 100 ~ 200cm that every L sewage puts into the surface area of filler3, react 24 ~ 48 hours;
(5) sewage processed through anaerobic reactor, surface liquid thorough fare aerobic reaction pond, base sludge is discharged after being passed through sludge drying pond pressure mud;
(6) every L sewage in aerobic reaction pond puts into the surface area of filler is 300 ~ 500cm3, react 24 ~ 48 hours;
(7) discharged the most afterwards by the water body behind aerobic reaction pond.
Wherein, the filling carrier in described step (4), step (5) is activated carbon or zeolite, toasts molding in 12 ~ 24 hours after sodium hydroxide infiltrates at 400 ~ 500 DEG C.
Wherein, the COD of described sanitary sewage and workshop sewage is 800 ~ 1200mg/L.
Wherein, in described step (2), alkali liquor is sodium hydroxide solution.
Wherein, described step (7) gained water body is passed through in step (3) described thinning tank, replaces tap water.
Beneficial effect: the present invention, compared with conventional art, acts on waste water jointly by the combination of materialization and biochemical method, makes up to discharging standards, and up to standard after the repeatable utilization of water body, further reduce pollution factor.
Detailed description of the invention
Embodiment 1:
