[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The MET composite ecological treatment component includes a housing and, from top to bottom, layers of anthracite, quartz sand, magnetite sand, activated carbon, and an adsorption chamber arranged within the housing. Sliding grooves are provided on the left and right sides of the inner wall of the housing, and sliding strips that slide and engage within the sliding grooves are provided on both sides of the adsorption chamber. An openable side door is also provided on the front of the housing for the adsorption chamber to slide out of the housing. The adsorption chamber includes several concentrically arranged annular drainage zones and annular adsorption zones. The annular drainage zone includes several circumferentially arranged UPVC porous pipes, with the upper end of each UPVC porous pipe connected to the outlet of the inlet hopper and the lower end closed. Several drainage holes are provided on the sidewalls of the UPVC porous pipes. The annular adsorption zone includes several circumferentially arranged lanthanum-loaded resin adsorption columns that adsorb and separate phosphate ions from the wastewater flowing out of the drainage holes.

Example

[0016] Please refer to Figures 1 to 2As shown, this utility model discloses a MET composite ecological treatment component, including a housing 1 and an interception chamber 2, a filtration chamber 3, and an adsorption chamber 4 arranged sequentially from top to bottom and connected within the housing 1. The interception chamber 2 includes several sets of interception grids 21 arranged along the height direction for intercepting large particulate impurities (such as tree branches). The filtration chamber 3 is used to remove suspended solids and colloids. The adsorption chamber 4 includes several annular water distribution zones 41 and annular adsorption zones 42 arranged concentrically and at intervals. A water inlet hopper 5 is provided below the filtration chamber 3. The annular water distribution zones 41 include several circumferentially arranged... A UPVC porous pipe 411 is installed, with its upper end connected to the outlet of the inlet hopper 5 and its lower end closed. The sidewall of the UPVC porous pipe 411 has several drainage holes 4111. The annular adsorption zone 42 includes several circumferentially arranged lanthanum-loaded resin adsorption columns 412 that adsorb and separate phosphate ions from the wastewater flowing out of the drainage holes 4111. The concentric annular drainage zones 41 and annular adsorption zones 42 are arranged alternately to allow the wastewater to diffuse radially, preventing short-circuiting and improving pollutant capture efficiency. A drain hopper 6 is installed below the adsorption chamber 4, with the lower end of the adsorption chamber 4 connected to the inlet of the drain hopper 6.

[0017] The adsorption chamber 4 is provided with an upper mounting plate 43 and a lower mounting plate 44. The upper mounting plate 43 is provided with several upper mounting ports that are connected vertically. The upper end of the UPVC porous pipe 411 is detachably connected to the upper mounting port through a threaded structure, and its upper end pipe opening is connected to the upper mounting port, thereby connecting to the water outlet of the water inlet hopper 5. The top surface of the lower mounting plate 44 is provided with several lower mounting grooves. The bottom end of the lanthanum resin adsorption column 421 is detachably connected to the lower mounting groove. The lower mounting plate 43 is provided with a lower water outlet that is connected vertically below the mounting ports, and the lower water outlet is connected to the water inlet of the drain hopper.

[0018] The lanthanum-loaded resin adsorption column 421 includes a resin skeleton and lanthanum ions loaded on the resin skeleton. A lower mounting head 422 is provided at the bottom end of the resin skeleton. The lower mounting head 422 is detachably inserted into the lower mounting groove through a threaded structure. The lanthanum ions are immobilized by the resin skeleton to achieve highly selective adsorption of phosphate ions without the generation of chemical sludge.

[0019] The inner walls of the housing 1 are provided with sliding grooves 11 on both the left and right sides. The adsorption chamber 4 is provided with sliding strips 45 on both sides that are slidably engaged in the sliding grooves 11. The front of the housing 1 is also provided with an openable side door for the adsorption chamber to slide out of the housing. The outer wall of the adsorption chamber 4 is inlaid with a sealing ring 46 along the circumference and is tightly fitted to the inner wall of the housing 1. The upper and lower ends of the housing 1 are respectively provided with an inlet 12 and an outlet 13.

[0020] The adsorption chamber 4 adopts a cross-sectional structure with an inner circle and an outer square. Its cylindrical inner cavity is open at both ends, and an annular step 47 is provided at each of its upper and lower ends. An upper mounting plate 43 and a lower mounting plate 44 are respectively placed over the upper and lower ends of the adsorption chamber 4 and supported by the annular step 47. Fixing bolts 48 are provided on the upper and lower mounting plates to lock into the annular step 47. The adsorption chamber 4 can be slid out of the housing 1 through the side door, and then the upper mounting plate 43 or the lower mounting plate 44 can be removed. Since the UPVC porous tube 411 and the lanthanum-loaded resin adsorption column 421 are detachably connected to the upper mounting port and lower mounting groove via a threaded structure, quick insertion and removal for maintenance and replacement are facilitated.

[0021] The filter chamber 3 comprises, from top to bottom, a layer of anthracite 31, a layer of quartz sand 32, a layer of magnetite sand 33, and a layer of activated carbon 34. The anthracite layer 31 has the lowest density and relatively coarse particles (e.g., 0.8-1.6 mm), mainly removing larger suspended solids, with strong interception capacity and extending the life of the lower filter media; the quartz sand layer 32 has a medium density and particle size (e.g., 0.5-0.8 mm), removing medium-sized particles; the magnetite sand layer 33 has the highest density and finest particles (e.g., 0.2-0.5 mm), serving as a fine filtration layer to remove fine particles and support the upper filter media; the activated carbon layer 34 is used to effectively adsorb and remove organic matter, residual chlorine, color, odor, etc. from the water.

[0022] There is a first adsorption gap between the annular water distribution zone 41 and the annular adsorption zone 42. There is a second adsorption gap between adjacent UPVC porous tubes 411 in the same group of annular water distribution zones 41. There is a third adsorption gap between adjacent lanthanum-loaded resin adsorption columns 421 in the same group of annular adsorption zones 42. The three sets of adsorption gaps form turbulence, which enhances solid-liquid contact.
