Wastewater to be treated is pumped into the dephosphorizing granular activated coke adsorption tower via a water pump, passes through the branch pipelines in the tower body, and enters the bottom of the granular activated coke to be pre-filtered, the pre-filtered wastewater passes through the water distributors which are arranged and combined under the granular activated coke according to the matrix, and uniformly passes through the filter layer, and the filtered water flows out uniformly, so that the purpose of removing total phosphorus in wastewater is realized due to the adsorption function of the granular activated coke, and the requirement of small occupied area can be met under the premise of meeting the special requirement of a large quantity of phosphorus wastewater; the operation is simple; the labor intensity is low; the wastewater treatment cost is low.
Description
Technical field
The invention belongs to biochemical water-treatment technology field, particularly relate to the automation equipment in a kind of water treatment procedure, total phosphorus being removed.
Background technology
In biochemical water treatment field, needing to be removed the total phosphorus in waste water, this process is adsorbed generally by seed activity Jiao and is removed.Prior art is to use the mode manually added to put into water treating pond dephosphorization seed activity Jiao; by adsorption produced by the pore structure that dephosphorization seed activity Jiao is flourishing; reach to remove the purpose of total phosphorus in water, then process technique or the qualified discharge of next stage will be flowed into by the supernatant of filter course.Such operational approach is simple; original; intake uneven; dephosphorization seed activity Jiao can not be adsorbed saturated uniformly during using; the labor intensity that later stage dephosphorization seed activity Jiao changes is big; during water processes, along with dephosphorization seed activity, Jiao is constantly adsorbed and progressivelyes reach saturated state, causes the water quality of water outlet constantly to decline.Simultaneously because underclad portion reaches saturated at first in filter course; upper strata adsorb the most completely saturated under; effluent quality has descended to underproof state; need dephosphorization seed activity Jiao in water treating pond is manually changed; the labor intensity of operating process is big; also part is adsorbed saturated dephosphorization seed activity Jiao the most completely to fall as waste disposal, cause the biggest economic waste, the management at Water purification station brings the biggest difficulty.
Summary of the invention
It is an object of the invention to the feature big for the treatment of Phosphorus Containing Waste Water water yield, it is provided that a kind of effective operation, thermopnore dephosphorization seed activity Jiao's adsorption tower of convenient management.
For this; the technical solution used in the present invention is such that thermopnore dephosphorization seed activity Jiao's adsorption tower; including tower body; it is characterized in that: tower body upper inside wall is provided with water inlet; water inlet connects some branch lines, is provided with some water-locators, described water-locator and branch line one_to_one corresponding in tower body; pending waste water enters tower body by water-locator, and tower body upper inside wall is additionally provided with corresponding outlet；Some water-locators in tower body combine arranged distribution according to matrix, and wherein the water-locator near tower body inwall is smaller in size than the water-locator at tower body center, and the area coverage of described water-locator is not less than the 90% of filter course sectional area；Seed activity it is filled with burnt in tower body；Being additionally provided with seed activity Jiao outside tower body and promote passage, described seed activity Jiao promotes in channel entrance is located at tower body bottom seed activity Jiao loaded, on seed activity Jiao top that outlet is loaded in being located at tower body.
Further, water-locator surface has hole, and pending waste water enters tower body by the hole of water-locator, and the hole of water-locator accounts for the ratio of its surface area and is more than 60%,
Further, described seed activity Jiao promotes passage and connects vacuum pump, utilizes negative pressure burnt to promote seed activity.
Further, present invention additionally comprises back purge system, seed activity Jiao in lifting process is rinsed.
During work; need to be squeezed into by water pump by waste water to be processed; by multiple branch lines in adsorption tower; enter into the bottom that seed activity is burnt; by bottom according to the water-locator of certain specification permutation and combination, waste water is uniformly by filter course, and water outlet is flowed out uniformly; under the adsorption function that seed activity is burnt, reach to remove the purpose of total phosphorus in water.General adsorption tower, one water-locator is only set in tower body, and the present invention is in adsorption tower, multiple water-locator is connected by branch line, described water-locator also combines arranged distribution with matrix, the area coverage making water-locator accounts for the 90% of filter course sectional area, makes the absorbability of adsorption tower be significantly improved, it is possible to meet the absorption demand of the big water-flowing amount of dephosphorization waste water.In adsorption tower, arrange the hoist point that multiple seed activity is burnt, in use for some time; seed activity Jiao of bottom is gradually adsorbed saturated; by seed activity, Jiao promotes passage, and seed activity Jiao of filter course bottom rises to the top of filter course, is circulated up and down by whole filter course and stirs.Seed activity Jiao adsorb saturated after, by seed activity Jiao promote passage by waste material propose.Inlet and outlet water mode of the present invention uses to go out on enterprising, and the bottom in and top out for general type cannot realize in this programme, and the most this water intake mode is the specific Inlet and outlet water scheme proposed for the present invention.The labor intensity that the present invention can not only solve to cause during artificial replacing dephosphorization seed activity Jiao is big, and dephosphorization seed activity Jiao uses insufficient problem, and automaticity is high, it is possible to the highly stable water quality ensureing water outlet.The invention has the beneficial effects as follows in a word, the total phosphorus in waste water can be removed, the sewage treatment plant that the discharge of all total phosphorus is the most up to standard can be docked at, the improvement of urban river water, ensure under the special demands for phosphorus-containing wastewater big yield, moreover it is possible to meet floor space little, simple to operate, hand labor intensity is low, and cost of sewage disposal is low.
