Description
Technical field
The present invention relates to technical field of sewage, and in particular to a kind of energy-conservation energy-conservation work of sewage disposal
Skill flow.
Background technology
Sewage disposal：It is to make sewage reach a certain water body of draining or the water quality requirement for reusing and right
Its process for being purified.Sewage disposal is widely used in building, agricultural, traffic, the energy, stone
The every field such as change, environmental protection, urban landscape, medical treatment, food and drink, also come into ordinary hundred more and more
The daily life of surname.Classify by sewage source, sewage disposal is generally divided into production wastewater treatment and life
Sewage disposal.Production waste is dirty by water including trade effluent, rural sewage and medical sewage etc.
Matter is divided, and the pollution of water has two classes：One class is natural pollution；Another kind of is artificial pollution.It is current right
It is artificial pollution that water body endangers larger.Water pollution can according to pollution impurity difference and being broadly divided into
Learn contact scar, physical pollution and biologic contamination three major types.Pollutant mainly has：(1) it is unprocessed
And the industrial wastewater for discharging；(2) it is unprocessed and discharge sanitary sewage；(3) largely using chemical fertilizer,
The farmland sewage of agricultural chemicals, herbicide；(4) trade waste and house refuse by the river is stacked；(5)
Soil erosion；(6) mine system engineering.
The method for processing sewage is a lot, can typically be summarized as Physical, chemical method and bioanalysis etc..
In the epoch that now grows prosperity in heavy industry, increasing heavy metal, the discharge of toxic material are got over
Come more, without treatment, can seriously exceed national standard, can be lived to the producer, periphery
And whole earth zone carrys out inconceivable trouble, due to the treatment such as waste water, sewage belong to high energy consumption,
A kind of inefficient mode, brings financial burden can thus to many enterprises, but if do not locate
Reason problem is more serious, can thus make the orientation direction vicious circle of enterprise.
The content of the invention
The technical problems to be solved by the invention be overcome existing technological deficiency provide a kind of environmental protection,
Energy-conservation, operating process are simple, a kind of energy-conservation energy-conservation technological process of sewage disposal of obvious processing effect.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of energy-conservation energy-conservation technological process of sewage disposal, it is characterised in that：Including following methods step,
(1) waste water containing heavy metal is collected through piping, into grid canal, by coarse rack, is gone
The larger suspended particulate substance of particle diameter in water removal；
(2) waste water after coarse rack is filtered is put into sump；
(3) supercharging that the waste water in sump is passed through into pump, by waste water lifting to regulating reservoir；
(4) submersible agitator by being installed in regulating reservoir is stirred, and waste water is realized that homogeneous is measured；
(5) waste water stirred in regulating reservoir is entered into PH regulating reservoirs by elevator pump；
(6) in PH regulating reservoirs adding NaOH solution improves the pH value of waste water；
(7) waste water in PH regulating reservoirs is sent into coagulation reaction tank, Fe systems is added in coagulation reaction tank
Flocculant improves the settleability of waste water；
(8) waste water of Fe based flocculating agents will be added to deliver to preliminary sedimentation tank carries out preliminary sedimentation；
(9) supernatant in preliminary sedimentation tank is made to flow to A/0 biochemistry pools certainly；
(10) waste water is in A/0 biochemistry pools, successively anaerobism, it is aerobic under conditions of, by microorganism
Decomposition, degradation go water removal in organic matter；
(11) waste water after decomposition is passed through in second pond, mud-water separation is carried out again；
(12) by the supernatant feeding intermediate pool in the pond after secondary precipitation；
(13) waste water of intermediate pool is lifted in charcoal canister by pump, is made by the absorption of activated carbon
With the heavy metal further gone in water removal；
(14) sterilization pool will be sent into by the waste water after charcoal absorption, is sterilized by sterilization pool, to
Extraneous qualified discharge.
Beneficial effects of the present invention are：The present invention be capable of will regenerate lead bullion, lead bullion, alloy lead,
The road when heavy metal-containing waste water, sanitary sewage, the rainy season that are produced in the production process such as lead oxide and battery
Road rainwater, treatment are clean, reach discharge standard, it is ensured that the reduction of pollution, serve the work of environmental protection
With.Environmental protection of the invention, energy-conservation, operating process are simple, treatment effect is aobvious.
In addition to objects, features and advantages described above, also other purposes of the invention,
Feature and advantage.Below with reference to figure, the present invention is further detailed explanation.
