Description

Pollute the treatment system of building waste
Technical field
The utility model relates to the process of solid-state castoff, especially pollutes the treatment system of building waste.
Background technology
Contaminated site showering (ex-situremediation) technology refers to be excavated by contaminated soil or underground water from the position occurring to pollute or extracts, and carries out the technology of administering after transport again.Implementing contaminated site, in showering process, not only to need to administer contaminated soil and groundwater, also need the building waste to adhering to contaminated soil to clean simultaneously.At present, for the building waste adhering to contaminated soil, main employing is manually carried out sorting and cleaning, and wastes time and energy.
In organic polluted soil and groundwater remediation, oxidant and be widely used with surfactant enhanced remediation technology but, can produce a large amount of surfactant wash liquid containing organic pollution in soil washing repair process, directly discharge may cause secondary pollution to environment.Exploiting economy, Surfactant cleaning solution recycling efficiently, remove the organic matter in cleaning solution, and realize the recovery and reuse technology of surfactant, the secondary pollution of discarded cleaning solution, the simultaneously recycling of surfactant not only can be avoided also effectively can to reduce rehabilitation cost.
Repair on-the-spot operating efficiency and the recycling of surfactant to improve, this is designed a set of screening flushing integration apparatus and replaces manually completing the sorting to contaminated building waste and cleaning.
Summary of the invention
The utility model object is, proposes a kind for the treatment of system polluting building waste.More reasonable structure is reliable, and the secondary pollution of discarded cleaning solution, the simultaneously recycling of surfactant not only can be avoided also effectively can to reduce rehabilitation cost.
The technical solution of the utility model is, pollutes the treatment system of building waste, comprises pulverizing-screening system, roller type conveyer belt, high-pressure washing system, stirring system, comprises preliminary sedimentation tank, the sludge treatment system of second pond and cleaning solution recovery system; High-pressure washing system is provided with above roller type conveyer belt, high-pressure washing system connects cleaning solution pharmacy jar, be provided with reactive tank below roller type conveyer belt, reactive tank connects preliminary sedimentation tank, second pond successively by pipeline, and the precipitating sludge in second pond is delivered to plate and frame type filter-press; Supernatant in the pressing filtering liquid of plate and frame type filter-press and second pond is connected to recovery filtration system through pipeline; Reactive tank is provided with stirring system.
Contaminated building waste is by after pulverizing-screening system, the building waste of Screening Network top greater particle size is to roller band, high-pressure washing system is provided with above roller type conveyer belt, high-pressure washing system connects cleaning solution pharmacy jar, topple over after staying the building waste high pressure washing above roller band to concentrate and stack, be provided with scrub raffinate accumulator tank below roller type conveyer belt, scrub raffinate enters preliminary sedimentation tank by pipeline; Through Screening Network comparatively small particle diameter building waste by conveyer belt, enter grid, after staying the building waste high pressure washing above grid, topple over concentrate stack, the building waste through grid stirs in reactive tank, stir after mud enter preliminary sedimentation tank by pipeline; Complete gravitational settling in preliminary sedimentation tank and discharge rear natural mummification containing the mud of small crushed stone, supernatant enters second pond, and the precipitating sludge in second pond is delivered to plate and frame type filter-press, completes disposal.Supernatant in pressing filtering liquid and second pond reclaims filtration system through pipeline to cleaning solution, pumps in cleaning solution pharmacy jar and re-use after process.
The utility model beneficial effect: the application of cleaning solution pharmacy jar, high-pressure washing system and post precipitation pond, by peristaltic pump, plate and frame type filter-press and cleaning solution are delivered to bottom thickened sludge reclaim supporting the use of the series of processes devices such as filter and avoid the secondary pollution of discarded cleaning solution, the simultaneously recycling of surfactant also effectively can reduce rehabilitation cost.The utility model is a kind of mechanical structure, has higher efficiency and disposal ability, is applicable to process various pollution building waste (comprising contaminated soil) on a large scale.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
See Fig. 1, wherein: 1. building waste (contaminated soil) breaker, 2. building waste (contaminated soil) screening plant, 3. conveyer belt, 4. cleaning solution pharmacy jar, 5. high-pressure washing system, 6. roller type conveyer belt, 7. scrub raffinate accumulator tank, 8. grid, 9. stirring system, 10. reactive tank, 11. preliminary sedimentation tanks, 12. second ponds, 13. plate and frame type filter-presses, 14. cleaning solutions reclaim filter.
The construction waste crushing device (employing disintegrating machine) that the utility model connects successively, conveyer belt are to building waste screening plant (adopting oscillatory type screening plant); Conveyer belt will need material to be processed (building waste of Screening Network top greater particle size) to be sent to roller type conveyer belt again; And be provided with high-pressure washing system above roller type conveyer belt, high-pressure washing system connects the liquid (oxidant adds surfactant) that cleaning solution pharmacy jar provides, material above roller type conveyer belt becomes normal material after removing pollutant, after cleaning solution washing, mixture flows out to below from roller gap and is provided with scrub raffinate accumulator tank and reactive tank, and scrub raffinate accumulator tank connects preliminary sedimentation tank by pipeline; By the comparatively small particle diameter of Screening Network by conveyer belt to grid, after staying the building waste high pressure washing above grid, topple over to concentrate and stack; Building waste through grid fully stirs in reactive tank, by pipeline to preliminary sedimentation tank; In preliminary sedimentation tank, complete gravitational settling discharge rear natural mummification containing the mud of small crushed stone, supernatant enters second pond.Precipitating sludge in second pond transports to plate and frame type filter-press by peristaltic pump, completes disposal.Supernatant in pressing filtering liquid and second pond reclaims filtration system through conveyance conduit to cleaning solution, pumps in cleaning solution pharmacy jar 4 and re-use after process.
