Abstract
The invention provides an environmental protective organic nutrient soil which consists of municipal sludge, phosphorite powder, the chemical raw material containing Fe<3plus> and the chemical raw material of Ca<2plus>. The environmental protective organic nutrient soil is made by the steps of compressing, stirring, pressing for sieving, crushing, mixing etc. The produced organic nutrient soil is used as the nutrient additive and soil improving agent of the garden plants. The invention realizes the effective combination of the sludge treatment and reutilization, which effectively prevents the secondary pollution caused by the sludge and as well as creates certain social value. The whole set of technology occupies small area; the structure is compact; the investment cost is low; the recovery benefit is great; the invention realizes the environmental protection process of changing the waste which pollutes the environment into the valuable product.
Description
Technical field
The invention belongs to field of sludge treatment, be specifically related to a kind ofly make organic mud and preparation technology thereof by mud.
Background technology
Along with the pay attention to day by day of modern society people to water resources, increasing urban wastewater treatment firm builds up in each cities and towns, the whole nation and comes into operation, this water pollution control to China positive effect of having got up.But in the process of sewage disposal, as handling two another source of pollution that become the city of essential active sludge.The water ratio height of active sludge, volume is big, rots easily, gives out stench, so the two urgent problems that become of the processing of mud.At present, the treatment process of mud has following several: soil utilization, landfill, burning, biochemical treatment and topple over and throw sea etc.For landfill, not only need enough big space and necessary environmental protective measure, also need the transport charge of writing simultaneously.In addition, now peri-urban has been difficult to find the space that is fit to landfill mud and place, and the secondary pollution problem that is produced by landfill also is becoming increasingly acute.Same, burning sludge needs a large amount of heat energy, therefore consumes a large amount of fuel, and the investment cost of burning facility is higher, and working cost is also very high, also produces a large amount of dusty gass simultaneously, expended substantial contribution again on to the processing of gas, the expense of handling mud like this is just very expensive.The most important thing is that these methods all can not bring any income to enterprise, is a kind of project of true investment, so the soil utilization just becomes development trend of sludge treatment.Doing fertile cost with making organic mud after the sludge treatment, both having saved, solved the secondary pollution problem of mud again, can also be good treatment method in for enterprise brings income simultaneously.
Summary of the invention
The purpose of this invention is to provide environmental organic nutrient soil a kind of environmental protection, that energy consumption is low and preparation technology and application.
The present invention is achieved in that a kind of environmental organic nutrient soil, it is characterized in that comprising following parts by weight: solid content is 60～80 parts of 5～35% municipal sludges, contains P

The preparation technology who the invention still further relates to a kind of environmental organic nutrient soil may further comprise the steps:
A, to get water ratio be 97～99.8% municipal sludge;
B, process thickner are compressed to 92～97% with the water ratio of mud;
C, interpolation contain Fe
3+Be 30～40% industrial chemicals;
D, stirring reaction;
E, interpolation contain Ca
2+It is 50～80% industrial chemicals;
F, stirring reaction;
G, through plate-and-frame filter press and under less than the pressure of 1.8MPa pressurize to be less than 100min be 55～70% with sludge dewatering to water ratio;
H, enter in the mixing machine broken;
I, in 1: 1 ratio with contain P
2O
5Be that 15～25% ground phosphate rock mixes.
After the described i step, be delivered to air-dry apparatus, stack a small amount of flyash, stacked seven days.
The invention still further relates to a kind of application of environmental organic nutrient soil, organic nutrient soil is as nutritional additive, the soil improvement agent of ornamental plant.
The present invention concentrates by mud earlier the mud of extracting out from sewage work's settling tank, adopt sorption concentrator, its principle of work is adsorbed for the water that adopts sorptive material will add in the mud of PAM (polyacrylamide), make the water ratio of mud that certain decline be arranged, the supernatant liquor of Pai Chuing is got back to the grid of sewage disposal simultaneously, reduce through spissated sludge volume, be convenient to the operation of subsequent technique.Then mud is carried out modifiedly, add when modified and contain 0.5～1.5% Fe
3+And Ca
2+Or any industrial chemicals wherein, mix the back and mud is injected pressure filter by pump, the water ratio of mud is dropped to about 55～70%.Filter cake after pressure filtration is introduced broken mixing machine by travelling belt, broken therein and mix according to certain ratio with nutrients such as ground phosphate rock, KCl, regulate the content of its nutrient and moisture.Mixed mud enters aerobic fermentation in the sludge air drying equipment, and the liberated heat of utilization own will promote its air-dry effect, and its water ratio is further reduced, and last water ratio obtains having the organic nutrient soil of utility value below 20%.At last organic nutrient soil is packed it by the pack module, formed the product of convenient outward transport.Realize that by automatic control module modified, dehydration, blending, the nutrient of mud are regulated, the automatic production of pack process.
The present invention has realized sludge treatment and effective combination of utilizing again, has both prevented the secondary pollution of mud effectively, has also created certain social value.Little, the compact construction of a whole set of technology floor space, investment cost is low, the recovery benefit is big, the refuse of contaminate environment is become the environmental protection process of value product.By the mud that this art breading is crossed, can be used as the ornamental plant organic mud, ornamental plant is cultivated culture bed nutritional additive, soil improvement agent and organic nutrient soil etc.
