Abstract
The invention discloses a harmless disposing method for red mud and ardealite.The method comprises the steps that the red mud and ardealite are mixed to be uniform to be prepared into slurry, or the red mud and ardealite are prepared into slurry and then mixed to be uniform; after mixing is conducted, the PH value of the slurry is neutral, or the PH value ranges from 6.5 to 7.5, and the PH value of diffusate meets the requirement of the grade III water quality or above in Environmental Quality Standards for Surface Water <GB3838-2002>.According to the harmless disposing method for the red mud and ardealite, harmful stockpiling is changed into harmless stockpiling, the stockpiling water environment is greatly protected, the most difficult problems of the aluminum smelting industry and the phosphorus chemical industry are technically solved, and a good foundation is laid for comprehensively utilizing waste materials of the aluminum smelting industry and the phosphorus chemical industry.
Description
Technical field
The invention belongs to field of environment protection, it relates to aluminum smelting technology and phosphorous chemical industry solid waste process and field of comprehensive utilization.
Background technology
Currently, the process of red mud is the technical bottleneck of restriction aluminum smelting technology industry, phosphogypsum process is the technical bottleneck of restriction sulphur dioxide of phosphor chemical industry too, these two kinds of trade wastes are stacked separately, the body of groundwater of locality is caused certain pollution by capital, occur the accident of dam break and water pollutions too numerous to mention, the disaster caused is startling, the process of red mud, phosphogypsum is the work that two relevant industries are extremely urgent, these two kinds of trade wastes can be carried out harmless treatment, just store up at last and also can not cause local groundwater pollution in earth's surface. The first step of the comprehensive regulation has been walked out in the harmless treatment of these two kinds of trade wastes, is a great invention of protection of the environment, turns waste into wealth lay a good foundation for carrying out comprehensive utilization further.
Summary of the invention
The technical problem to be solved in the present invention is: provides a kind of red mud and ardealite innocent method of disposal, solves the big difficult problem of trade waste of aluminum smelting technology and phosphorous chemical industry two industries, solve two kinds of solid waste and store up separately the pollution problem to body of groundwater.
The technical scheme of the present invention is a kind of red mud and ardealite innocent method of disposal, comprises following two schemes specifically:
Scheme one comprises the steps:
1. red mud and phosphogypsum, are made slurry body by step, and namely both be prepared into slurry body state respectively;
Step is 2., according to quality than red mud: phosphogypsum=1:6～1:10 carries out Homogeneous phase mixing, and (1:6～1:10 here is equivalent to red mud: phosphogypsum=1:6～10, namely the scope between 1:6 to 1:10 is comprised, such as 1:7,1:6.5 etc.), by step 1. in preparation red mud and phosphogypsum slurry body carry out Homogeneous phase mixing according to aforementioned proportion, guarantee mixed slurry body PH value in neutral or PH value between 6.5～7.5, and the PH value of its transudate reaches three class water quality in water environment quality standard " GB3838-2002 " and above requirement;
Step 3., store up or for other utilization with storing up by conveying.
Scheme two comprises the steps:
Step 1., by red mud and phosphogypsum according to red mud: phosphogypsum=1:6～1:10(mass ratio) carry out Homogeneous phase mixing (1:6～1:10 here is equivalent to red mud: phosphogypsum=1:6～10, namely comprises the scope between 1:6 to 1:10, such as 1:7,1:6.5 etc.);
Step 2., by step 1. in compound make slurry body, it is ensured that slurry body PH value in neutrality or PH value between 6.5～7.5, and the PH value of its transudate reaches three class water quality in water environment quality standard " GB3838-2002 " and above requirement;
Step 3., store up or for other utilization with storing up by conveying.
The present invention inherently solves red mud, phosphogypsum and stores up separately the pollution to water surrounding, and maximum bright spot is that by chemical property be the method that the phosphogypsum that alkaline red mud and chemical property are acid carries out combination treatment.
Embodiment
Embodiment 1
A kind of red mud and ardealite innocent method of disposal, comprise the following steps:
1. red mud and phosphogypsum, are made slurry body by step respectively;
Step is 2., according to quality than red mud: phosphogypsum=1:6 step 1. in preparation red mud and phosphogypsum slurry body Homogeneous phase mixing, guarantee mixture slurry PH value in neutral or PH value between 6.5～7.5, at the same time it is assured that red mud and phosphogypsum mix the three class water quality requirements that its PH value (potential of hydrogen) of transudate can reach in water environment quality standard " GB3838-2002 ";
Step 3., store up or for other utilization with storing up by conveying.
Embodiment 2
A kind of red mud and ardealite innocent method of disposal, comprise the following steps:
Step 1., by red mud and phosphogypsum according to quality than red mud: phosphogypsum=1:10 Homogeneous phase mixing;
Step is 2., mixture step 1. obtained makes slurry body, guarantee slurry body PH value in neutrality or PH value between 6.5～7.5, at the same time it is assured that red mud and phosphogypsum mix the three class water quality requirements that its PH value (potential of hydrogen) of transudate can reach in water environment quality standard " GB3838-2002 ";
Step 3., store up or for other utilization with storing up by conveying.
According to above-described embodiment 1 or 2 step 1.～3. implement after; red mud and phosphogypsum mix the three class water quality requirements that transudate PH value (potential of hydrogen) can reach in water environment quality standard " GB3838-2002 "; harmful storing up is become harmless storing up; make to store up water surrounding and obtain great protection; solve aluminum smelting technology and a maximum difficult problem for phosphorous chemical industry two industries technically, lay a good foundation for fully utilizing these two kinds of trade wastes.
Claims (4)
1. a red mud and ardealite innocent method of disposal, it is characterized in that: by red mud and phosphogypsum Homogeneous phase mixing, mixed PH value is in neutral or PH value between 6.5～7.5, and the PH value of its transudate reaches three class water quality in water environment quality standard " GB3838-2002 " and above requirement.
