Due to the large amount of a£ ©☆quaculture sewage and a lot of suspen™•±↓ded solids, the triangular ↑∏water-cut wedge mesh used✔ ₹ in the inclined screen solid-liquid©$ separator can separate a✘₽nd squeeze most of the sus★ ÷pended solids, and the σ∑★suspended solids in the separat←×₹ed sewage are reduced•λδ , which greatly reduces the investment≠ ® and operating costs of the sewa​♠πge follow-up treatment equipment.

Two, the working principle

The wastewater to be treatedφ≥×☆ is evenly distributedδγ to the inclined screen surfac↓λe through the overflow weir<₹®¥, and is filtered thro£♦ugh the inclined screen surf¥∞σ∞ace for primary filtration. The π∏screen surface gap is s∞≥≠mall and smooth, and the ∞≠ back gap is large, so the drainage i←€s smooth, and the solid  ∞α±is trapped, and the filtered water fl±φows out from the gap o∑∑₹f the screen plate. Und₽≈er the hydraulic actiγ​≠on, the solid is pushed to the lower e↕∏α§nd of the screen plate €<and enters the strainer sc$'reen for secondary filtratiβ♣ on. Then the winch will push the s♥α©olid into the screen ro®₽und filter screen for three-stageγ≈≤ filtration, and finally the winch Ωγ‍will pressure the solid to ope↕★n the blocking device,  ¥✘so as to achieve the®¥ purpose of solid-liquid separat∑'♠ion.  

Three, equipment characteristic₽<δs

1. The volume of the old biogas digσ≥ester originally built by the f≤↑±armers is too small, and the<≤π¶ drainage time of the sewage into th₩©₹∏e pool is too short, res♥♠ulting in the sewage concentratioα§Ω™n being discharged too hi₹₹ ±gh, if the sewage is first treated b←≤≠y the inclined screen solid liquid sep→≥arator before it is submerged i♦δn the pool. It can effectively r♠£educe the content of COD and BOD in se¶Ω∏wage, reduce the operating load of biσ≠∑‌ogas digester, and achieve the re™₽duction and reduction of sewage discha&"≈rge;

2. The sewage separate♠£d by the inclined sieve type∑β solid-liquid separator ent®€ers the biogas digester intermiπ'∑ttently, which can make ✔↕♦the anaerobic pool have a ♣×±βfull digestion time, ∏♣×so that the active bacteria i‍ ≈•n the pool can reproduce more vigo©©rously and the gas product€≥ion is higher;

3. The sewage separated by the iφε∏↑nclined sieve type soli♠>d-liquid separator enters thαφ↔"e biogas digester, which can effe✔"ctively solve the crust phenomeΩ'"non of the biogas digester and eli←★>αminate the work of cleaning the γ® ≈biogas residue;

4. The use of livestock and€γ€• poultry manure solid<$-liquid separator can reduce↑> the construction investment®©♦ of biogas digester.
